In no event will the Contract Times commence to run later than the sixtieth day after the day of Bid opening or the thirtieth day after the Effective Date of the Agreement, J whichever date is earlier. 2.04 Starting the Work A. CONTRACTOR shall start to perform the Work on the date when the Contract Times commence to run. No Work shall be done at the Site prior to the date on which the Contract Times commence to run. 2.05 Before Starting Construction A. CONTRACTOR's Review of Contract Documents: Before undertaking each part of the Work, CONTRACTOR shall carefully study and compare the Contract Documents and check and verify pertinent figures therein and all applicable field measurements. CONTRACTOR shall promptly report in writing to ENGINEER any conflict, error, ambiguity, or discrepancy which CONTRACTOR may discover and shall obtain a written interpretation or clarification from ENGINEER before proceeding with any Work affectedthereby; however, CONTRACTOR shall not be liable to OWNER or ENGINEER for failure to report any conflict, error, ambiguity, or discrepancy in the. Co~tract Documents unless CONTRACTOR knew or reasonably should have known thereof. B. Preliminary Schedules: Within ten days after the Effective Date of the Agreement (unless otherwise specified 00700 - 9 in the General Requirements), CONTRACTOR shall submit to ENGINEER for its timely review: 1. a preliminary progress schedule indicating the times (numbers of days or dates) for starting and completing the various stages of the Work, including any Milestones specified in the Contract Documents; 2. a .preliminary :schedule of Shop Drawing and Sample submittals which will list each required submittal and the times for submitting, reviewing, and processing such submittal; and 3. a preliminary schedule of values for all of the Work which includes quantities and prices of items which when added together equal the Contract Price and subdi- vides the Work into component parts in sufficient detail to serve as the basis for progress payments during performance of the Work. Such prices. will include an appropri;lte amount of overhead and profit applicable to each item of Work. C. Evidence of Insurance: Before any Work at the Site is started, CONTRACTOR and OWNER shall each deliver to the other, with copies to each additional insured identified in the Supplementary Conditions, certificates of insurance (and other evidence of insurance which either of them or any additional insured may reasonably request) which CONTRACTOR and OWNER respectively are required to purchase and maintain in accordance with Article 5. 2.06 Preconstruction Conference A.

Unless otherwise provided in the Contract Docu- ments, at least ten days before submission of the fIrst Application for Payment a conference attended by CON- TRACTOR, ENGINEER, and others as appropriate will be held to review for acceptability to ENGINEER as provided below the schedules submitted in accordance with paragraph 2.05.B. CONTRACTOR shall have an additional ten days to make corrections and adjustments and to complete and resubmit the schedules. No progress payment shall be made to CONTRACTOR until acceptable schedules are submitted to ENGINEER. 00700 - 10 I 1. The progress schedule will be acceptable to ENGINEER if it provides an orderly progression of the Work to completion within any specified Milestones and the Contract Times. Such acceptance will not impose on ENGINEER responsibility for the progress schedule, for sequencing, scheduling, or progress of the Work nor interfere with or relieve CONTRACTOR from CONTRACTOR's full responsibility therefor. I I I 2. CONTRACTOR's schedule of Shop Drawing and Sample submittals will be acceptable to ENGINEER if it provides a workable arr~gement I f9r reviewing and processing the required submittals. I " 3. CONTRACTOR's schedule of values will be acceptable-ta-ENGINEER as to form and substance if it provides a reasonable allocation of the Contract Price to component parts of the Work.

LANDS; SUBSURFACE AND PHYSICAL CONDITIONS; REFERENCE POINTS 4.01 Availability of Lands A. OWNER.shall furnish the Site. OWNER shall notify CONTRACTOR of any encumbrances or restrictions not of general application but specifically related to use of the Site with which CONTRACTOR must comply in performing the Work. OWNER will obtain in a timely manner and pay for easements for permanent structures or permanent chaIlges in existing facilities. If CONTRACTOR and OWNER are unable to agree on entitlement to or on the amount or extent, if any, of any adjustment in the Contract Price or Contract Times, or both, as a result of any delay in OWNER's furnishing the Site, CONTRACTOR may make a Claim therefor as provided in paragraph 10.05. 00700 - 11 B. Upon reasonable written re"quest, OWNER shall furnish CONTRACTOR with a current statement of record legal title and legal description of the lands upon which the Work is to be performed and OWNER's interest therein as necessary for giving notice of or filing a mechanic f s or construction lien against such lands in accordance with applicable Laws and Regulations. C. CONTRACTOR shall provide for all additional lands and access thereto that may be required for temporary construction facilities or storage of materials and equipment. 4.02 Subsurface and Physical Conditions A. Repons and Drawings: Conditions identify: The Supplementary 1. those reports of explorations and tests of subsurface conditions at or contiguous to the Site that ENGINEER has used in preparing the Contract Docu- ments; and 2. those drawings of physical conditions in or relating to existing surface or subsurface structures at or contiguous to the Site (except Underground Facilities) that ENGINEER has used in preparing the Contract Documents. B. Limited Reliance by CONTRACl'OR on Technical Data Authorized: CONTRACTOR may rely upon the general accuracy of the "technical data" contained in such reports and drawings, but such reports and drawings are not Contract Documents. Such" technical data" is identified in the Supplementary Conditions. Except for such reliance on such "technical data," CONTRACTOR may not rely upon or make any Claim against OWNER, ENGINEER, or any of ENGINEER's Consultants with respect to: 1. the completeness of such reports and drawings for CONTRACTOR's purposes, including, but not limited to, any aspects of the means, methods, techniques, sequences, and procedures of construction to be employed by CONTRACTOR, and safety precautions and programs incident thereto; or 2. other data, interpretations, OplDlOns, and information contained in such reports or shown or indicated in such drawings; or 3. any CONTRACTOR interpretation of or conclusion drawn from any "technical data" or any such other data, interpretations, opinions, or information. 00700 - 12 4.03 Differing Subsurface or Physical Conditions A. Notice: If CONTRACTOR believes that any subsur- face or physical condition at or contiguous to the Site that is uncovered or revealed either: 1. is of such a nature as to establish that any "technical data" on which CONTRACTOR is entitled to rely as provided in paragraph 4.02 is materially inaccurate; or 2. is of such a nature as to require a change in the Contract Documents; or ., 3. differs materially from that shown or indicated in the Contract Documents;. or 4. is of an unusual nature, and differs materially from conditions ordinarily encountered and generally recognized as inherent in work of the character provided for in the Contract Documents; then CONTRACTOR shall, promptly after becoming aWare thereof and before further disturbing the subsurface or physical conditions or performing any Work in connection therewith (except in an emergency as required by paragraph 6.16.A), notify OWNER and ENGINEER in writing about such condition. CONTRACTOR shall not further disturb such condition or perform any Work in connection therewith (except as aforesaid) until receipt of written order to do so. B. . ENGINEER's Review: After receipt of written notice as required by paragraph 4.03.A, ENGINEER will promptly review the pertinent condition, determine the necessity of OWNER's obtaining additional exploration or tests with respect thereto, and advise OWNER in writing (with a copy to CONTRACTOR) of ENGINEER's fmdings and conclusions . C. Possible Price and Times Adjustments 1. The Contract Price or the Contract Times, or both, will be equitably adjusted to the extent that the existence of such differing subsurface or physical condition causes an increase or decrease in CONTRACTOR's cost of, or time required for, perfor- mance of the Work; subject, however, to the following: a. such condition must meet anyone or more of the categories described in paragraph 4.03.A; and b. with respect to Work that is paid for on a Unit Price Basis, any adjustment in Contract Price will be subject to the provisions of paragraphs 9.08 and 11.03. I I I I I I I I I I I I I I I I I I I I I I 2. CONTRACTOR shall not be entitled to any adjustment in the Contract Price or Contract Times if: a. CONTRACTOR knew of the existence of such conditions at the time CONTRACTOR made a fmal commitment to OWNER in respect of Contract Price and Contract Times by the submission of a Bid or becoming bound under a negotiated contract; or I I b. the existence of such condition could reasonably have been discovered or revealed as a result of any examination, investigation, exploration, test, or study of the Site and contiguous areas required. by the Bidding Requirements or Contract Documents to be conducted by or for CON- TRACTOR prior to CONTRACTOR's making such fmal commitment; or I I I c. CONTRACTOR failed to give the written notice within the time and as required by paragraph 4.03.A. I I 3. If OWNER and CONTRACTOR are unable to agree on entitlement to or on the amount or extent, if any, of~ any adjustment in the Contract Price or Contract Times, or both, a Claim may be made therefor as provided in paragraph 10.05. However, OWNER, ENGINEER, and ENGINEER's Consultants shall not be liable to CONTRACTOR for any claims, costs, losses, or damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by CONTRACTOR on or in connection with any other project or anticipated project. I I 4.04 Underground Facilities I I A. Shown or Indicated: The information and data shown or indicated in the Contract Documents. with respect to existing Underground Facilities at or contiguous to the Site is based on information and data furnished to OWNER or ENGINEER by the owners of such Underground Facilities, including OWNER, or by others. Unless it is otherwise expressly provided in the Supplementary Conditions: I I 1. OWNER and ENGINEER shall not be responsible for the accuracy or completeness of any such information or data; and I 2. the cost of all of the following will be included in the Contract Price, and CONTRACTOR shall have full responsibility for: I a. reviewing and checking all such information and data, I 00700 - 13 b. locating all Underground Facilities shown or indicated in the Contract Documents, c. coordination of the W o!k with the owners of such Underground Facilities, including OWNER, during construction, and d. the safety and protection of all such Under- ground Facilities and repairing any damage thereto resulting from the Work. B. Not Shown or Indicated , i' , 1. If an Underground Facility is uncovered or ., revealed at or contiguous to the Site which was not shown or indicated, or not shown or indicated with reasonable accuracy in the Contract Documents, CONTRACTOR shall, promptly after becoming aware thereof and before further disturbing conditions affected thereby or performing any Work in connection therewith (except in an emergency as required by paragraph 6.16.A), identify the owner of such Underground Facility and give written notice to that owner and to OWNER and ENGINEER. ENGINEER will promptly review the Underground Facility and determine the extent, if any, to which a change is required in the Contract Documents to reflect and document the consequences of the existence or location of the Underground Facility. During such time, CONTRACTOR shall be responsible for the safety and protection of such Underground Facility. 2. If ENGINEER concludes that a change in the Contract Documents is required, a Work Change Directive or a Change Order will be issued to reflect and document such consequences. An equitable adjustment shall be made in the Contract Price of Contract Times, or both, to the extent that they are attributable to the existence or location of any Underground Facility that was not shown or indicated or not shown or indicated with reasonable accuracy in the Contract Documents and that CONTRACTOR did not know of and could not reasonably have been expected to be aware of or to have anticipated. If OWNER and CONTRACTOR are unable to agree on entitlement to or on the amount or extent, if . any, of any such adjustment in Contract Price or Contract Times, OWNER or CONTRACTOR may make a Claim therefor as provided in paragraph 10.05. 4.05 Reference Points A. OWNER shall provide engineering surveys to establish reference points for construction which in ENGINEER's judgment are necessary to enable CON- TRACTOR to proceed with the Work.

If CONTRACTOR encounters a Hazardous Environmental Condition or. if CONTRACTOR or anyone for whom CONTRACTOR is responsible creates a Hazardous 00700 - 14 I Environmental Condition, CONTRACTOR shall immedi- ately: (i) secure or otherwise isolate such condition; (ii) stop all Work in connection with such condition and in any area affected thereby (except in an emergency as required by paragraph 6.16); and (iii) notify OWNER and ENGINEER (and promptly thereafter confrrm such notice in writing). OWNER shall promptly consult with ENGINEER concerning the necessity for OWNER to retain a qualified expert to evaluate such condition or take corrective action, if any. I I I E. CONTRACTOR shall not be required to resume Work in connection with such conditiol1l'or in any affected area until after OWNER has obtained any required permits related thereto and delivered to CONTRACTOR written ., notice: (i) specifying that such condition and. any affected area is or has been rendered safe for the resumption of Work; or (ii) specifying any special conditions under which such Work may be resumed safely. If OWNER and CONTRACTOR cannot agree as to entitlement to or on the amount or extent, if any, of any adjustment in Contract Price or Contract Times, or both, as a result of such Work stop- page or such special conditions under which Work is agreed to be resumed by CONTRACTOR, either party may make a Claim therefor as provided in paragraph 10.05. I I I I, I F. If after receipt of such written notice CONTRACTOR does not agree to resume such Work based on a reasonable belief it is unsafe, or does not agree to resume such Work under such special conditions, then OWNER may order the portion of the Work that is in the area affected by such condition to be deleted from the Work. If OWNER and CONTRACTOR cannot agree as to entitlement to or on the amount or extent, if any, of an adjustment in Contract Price or Contract Times as a result of deleting such portion of the Work, then either party may make a Claim therefor as provided in paragraph 10.05. OWNER may have such deleted portion of the Work performed by OWNER's own forces or others in accordance with Article 7. I I I I I I G. To the fullest extent permitted by Laws and Regulations, OWNER shall indemnify and hold harmless CONTRACTOR, Subcontractors, ENGINEER, ENGINEER's Consultants and the officers, directors, partners, employees, agents, other consultants, and subcontractors of each and any of them from and against all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to a Hazardous Environmental Condition, provided that. such Hazardous Environmental Condition: (i) was not shown or indicated in the Drawings or Specifications or identified in the Contract Documents to be included within the scope of the Work, and (ii) was not created by CONTRACTOR or by anyone for whom CONTRACTOR is responsible.

Without prejudice to any other right or remedy, the other party may elect to obtain equivalent Bonds or insurance to protect such other party t s interests at the expense of the party who was required to provide such coverage, and a Change Order shall be issued to adjust the Contract Price accordingly. I I I 5.10 Partial Utilization, Acknowledgment of Property Insurer '..' I ,A. If OWNER fmds it necessary to occupy or use a ., portion or portions of the Work prior to Substantial Completion of all the Work as provided in paragraph 14.05, no such use or occupancy shall commence before the insurers providing the property insurance pursuant to paragraph 5.06 have acknowledged notice thereof and in writing effected any changes in coverage necessitated thereby. The insurers providing the property insurance shall consent by endorse- ment on the policy or policies, but the property insurance shall not be canceled or permitted to lapse on account of any such partial use or occupancy. I I I I ARTICLE 6 - CONTRACTOR'S RESPONSIBILITIES I 6.01 Supervision and Superintendence I I A. . CONTRACTOR shall supervise, inspect, and direct the Work competently and efficiently, devoting such attention thereto and applying such skills and expertise as may be necessary to perform the Work in accordance with the Contract Documents. CONTRACTOR shall be solely responsible for the means, methods, techniques, sequences, and procedures of construction, but CONTRACTOR shall not be responsible for the negligence of OWNER or ENGINEER in the design or specification of a specific means, method, technique, sequence, or procedure of construction which is shown or indicated in and expressly required by the Contract Documents. CONTRACTOR shall be responsible to see that the completed Work complies accurately with the Contract Documents. I I I B. At .a11 times during the progress of the Work, CONTRACTOR shall assign a competent resident superin- tendent thereto who shall not be replaced withoutl written notice to OWNER and ENGINEER except under extraordinary circumstances. The superintendent will be CONTRACTOR's representative at the Site and shall have authority to act on behalf of CONTRACTOR. All communications given to or received from the superintendent shall be binding on CONTRACTOR. I I I 00700 - 18 I I I 6.02 Labor; Working Hours I A. CONTRACTOR shall provide competent, suitably qualified personnel to survey, layout, and construct the Work as required by the Contract Documents. CON- TRACTOR shall at all times maintain good discipline and order at the Site. I B. Except as otherwise required for the safety or protection of persons or the Work or property at the Site or adjacent thereto, and except as otherwise stated in the Contract Documents, all Work at the Site shall be performed dwing regular working hours, and CONTRACTOR will not permit overtime work or the performance of Work on Saturday, Sunday, or any legal holiday without OWNER's written consent (which will not be unreasonably withheld) given after prior written notice to ENGINEER. I I I 6.03 Services, Materials, and Equipment I A. Unless otherwise specified in the General Re- quirements, CONTRACTOR shall provide and assume full responsibility for all services, materials, equipment, labor, transportation, construction equipment and machinery, tools, appliances, fuel, power, light, heat, telephone, water, sanitary facilities, temporary facilities, and all other facilities and incidentals necessary for the performance, testing, start-up, and completion of the Work. I I I .B. All materials and equipment incorporated into the Work shall be as specified or, if not specified, shall be of good quality and new, except as otherwise provided in the Contract Documents. All warranties and guarantees specifically called for by the Specifications shall expressly run to the benefit of OWNER. If required by ENGINEER, CONTRACTOR shall furnish satisfactory evidence (including reports of required tests) as to the source, kind, and quality of materials and equipment. All materials and equipment shall be stored, applied, installed, connected, erected, protected, used, cleaned, and conditioned in accordance with. instructions of the applicable Supplier, except as otherwise may be provided in the Contract Docu- ments. I I I I 6.04 Progress Schedule I A. CONTRACTOR shall adhere to the progress schedule established in accordance with paragraph 2.07 as it may be adjusted from time to time as provided below. I 1. CONTRACTOR shall submit to ENGINEER for acceptance (to the extent indicated in paragraph 2.07) proposed adjustments in the progress schedule that will not result in changing the Contract Times (or Milestones). Such adjustments will conform generally to the progress schedule then in effect and additionally will comply with I I 00700 - 19 any provisions of the General Requirements applicable thereto. 2. Proposed adjustments in ~e progress schedule that will change the Contract Times (or Milestones) shall be submitted in accordance with the requirements of Article 12. Such adjustments may only be made by a Change Order or Written Amendment in accordance with Article 12. 6.05 Substitutes and "Or-Equals" II A. Whenever an item of material or equipment is spe~ified or described in the Contract Documents by using ., the name of a proprietary item or the name ofa particular Supplier, the specification or description is intended to establish the type, function, appearance, and quality required. Unless the specification or description contains or is followed by words reading that no like, equivalent, or "or-equal" item or no substitution is permitted, other items of material or equipment or material or equipment' of other Supplier~ may be submitted to ENGINEER for review under the circum- stances described below. 1. "Or-Equal" Items.. If in ENGINEER's sole discretion an item of material or equipment proposed by CONTRACTOR is functionally equal to that named and sufficiently similar so that no change in related Work will be required, it may be considered by ENGINEER as an "or-equal" item, in which case review and approval of the proposed item may,.in ENGINEER's sole discretion, be accomplished without compliance with some or all of the requirements for approval of proposed substitute items. For the purposes of this paragraph 6.05.A.l, a proposed item of material or equipment will be considered functionally equal to an item so named if: a. in the exercise of reasonable judgment ENGINEER determines that: (i) it is at least equal in quality, durability, appearance, strength, and design characteristics; (ii) it will reliably perform at least equally well the function imposed. by the design concept of the completed Project as a functioning whole, and; b. CONTRACTOR certifies that: (i) there is no increase in cost to the OWNER; and (ii) it will conform substantially, even with deviations, to the detailed requirements of. the item named in the Contract Documents. 2. Substitute Items a. If in ENGINEER's sole discretion an item of material or equipment proposed by CONTRACTOR does not qualify as an "or-equal" item under paragraph 6.05.A.l, it will be~considered a proposed substitute item. b. CONTRACTOR shall submit sufficient information as provided below to allow ENGINEER to determine that the item of material or equipment proposed is essentially equivalent to that named and an acceptable substitute therefor. Requests for review of proposed substitute items of material or equipment will not be accepted by ENGINEER from anyone other than CONTRACTOR. c. The procedure for review by ENGINEER will be as set forth in paragraph 6.05.A.2.d, as supplemented in the General Requirements and as ENGINEER may decide is appropriate under the circumstances. d. CONTRACTOR shall fIrst make written app!ication to ENGINEER for review of a proposed substitute item of material or equipment that CONTRACTOR seeks to furnish or use. The application shall certify that the proposed substitute item will perform adequately the functions and achieve the results called for by the general design, be similar in substance to that specified, and be suited to the same use as that specified. The application will state the extent, if any, to which the use of the proposed substitute item will prejudice CONTRACTOR's achievement. of Substantial Completion on time, whether or not use of the proposed substitute item in the Work will require a change in any of the Contract Documents (or in the provisions of any other direct contract with OWNER for work on the Project) to adapt the design to the proposed substitute item and whether or not incorporation or use of the proposed substitute item in connection with the Work is subject to payment of any license fee or ~ royaltY. All variations of the pro- posed substitute item from that specified will be identified in the application, and available engineering, sales, maintenance, repair, and replacement services will be indicated. The application will also contain an itemized estimate of all costs or credits that will result directly or indi- rectly from . use of such substitute item, including costs of redesign and claims of other contractors affected by any resulting change, all of which will be considered by ENGINEER in evaluating the proposed substitute item. ENGINEER may require CON- TRACTOR to furnish additional data about the pro- posed substitute item. B. Substitute Construction Methods or Procedures: If a specific means, method, technique, sequence, or procedure of construction is shown or indicated in and expressly 00700 - 20 I required by the Contract Documents, CONTRACTOR may furnish or utilize a substitute means, method, technique, sequence, or procedure of construction approved by ENGI- NEER. CONTRACTOR shall submit sufficient information to allow ENGINEER, in ENGINEER's sole discretion, to determine that the substitute proposed is equivalent to that expressly called for by the Contract Documents. The proce- dure for review by ENGINEER will be similar to that provided in subparagraph 6.05.A.2. I I I I C. Engineer's Evaluation: ENGINEER will be allowed a reasonable time within which to evaluate each proposal or submittal made pursuant to paragraphs 6.05.A and 6.05.B. ENGINEER will be the sole judge of acceptability. No ., "or -equal" or substitute will be ordered, installed or utilized until ENGINEER's review is complete, which will be evidenced by either a Change Order for a substitute or an approved Shop Drawing for an "or equal." . ENGINEER will advise CONTRACTOR in writing of any negative determination. I I I D. Special Guarantee: OWNER may require CON- TRACTOR to furnish at CONTRACTOR's expense a special performance guarantee or other surety with respect to any substitute. I E. ENGINEER's Cost Reimbursement: ENGINEER will record time required by ENGINEER and ENGINEER's Consultants in evaluating substitute proposed or submitted by CONTRACTOR pursuant to paragraphs 6.05.A.2 and 6.05.B and in making changes in the Contract Documents (or in the provisi9ns of any other direct contract with OWNER for work on the Project) occasioned thereby. Whether or not ENGINEER approves a substitute item so proposed or submitted by CONTRACTOR, CONTRACTOR shall reimburse OWNER for the charges of ENGINEER and ENGINEER's Consultants for evaluating each such proposed substitute. I I I I I F. CONrRACFOR's Expense: CONTRACTOR shall provide all data in support of any proposed substitute or "or-equal" at CONTRACTOR's expense. 6.06 Concerning Subcontractors, Suppliers, and Others I A. CONTRACTOR shall not employ any Subcontractor, Supplier, or~. other individual or entity (including those acceptable to OWNER as indicated in paragraph 6.06.B), whether initially or as a replacement, against whom OWNER may have reasonable objection. CONTRACTOR shall not be required to employ any Subcontractor, Supplier, or other individual or entity to furnish or perform any of the Work against whom CONTRACTOR has reasonable objection. I I B. If the Supplementary Conditions require the identity of certain Subcontractors, Suppliers, or other ~dividuals or I I I I entities to be submitted to OWNER in advance for acceptance by OWNER by a specified date prior to the Effective Date of the Agreement, and if CONTRACTOR has submitted a list thereof in accordance with the Supplementary Conditions, OWNER's acceptance (either in writing or by failing to make written objection thereto by the date indicated for acceptance or objection in the Bidding Documents or the Contract Documents) of any such Subcontractor, Supplier, or other individual or entity so identified may be revoked on the basis of reasonable objection after due investigation. CON- TRACTOR shall submit an acceptable replacement for the rejected Subcontractor, Supplier, or other individual or entity, and the Contract Price will be adjusted by the differ- ence in the cost occasioned by such replacement, and an appropriate Change Order will be issued or Written Amendment signed. No acceptance by OWNER of any such Subcontractor, Supplier, or other individual or entity, whether initially or as a replacement, shall constitute a waiver of any. right of OWNER or ENGINEER to reject defective Work. I I I I I I C. CONTRACTOR shall be fully responsible to OWNER and ENGINEER for all acts and omissions of the Subcontractors, Suppliers, and other individuals or entities performing or furnishing any of the Work just as CONTRACTOR is responsible for CONTRACTOR's own acts and omissions. Nothing in the Contract Documents shall create for the benefit of any such Subcontractor, Supplier, or other individual or entity any contractual relationship between OWNER or ENGINEER and any such Subcontractor, Supplier or other individual or entity, nor shall it create any obligation on the part of OWNER or ENGINEER to payor to see to the payment of any moneys due any such Subcon- tractor ~ Supplier, or other individual or entity except as may otherwise be required by Laws and Regulations. I li~ I I I I -. D. CONTRACTOR shall be solely responsible for scheduling and coordinating the Work of Subcontractors, Suppliers, and other individuals or entities performing or ~shing any of the Work under a.direct or indirect contract with CONTRACTOR. I E. CONTRACTOR shall require all Subcontractors, Suppliers, and such other individuals or entities performing or furnishing any of the Work to communicate with ENGI- NEER through CONTRACTOR. I F. The divisions and sections of the Specifications and the identifications of any Drawings shall not control CONTRACTOR in dividing the Work among Subcontractors or Suppliers or delineating the Work to be performed by any specific trade. I I G. All Work performed for CONTRACTOR by a Subcontractor or Supplier will be pursuant to an appropriate agreement between CONTRACTOR and the Subcontractor I or Supplier which specifically binds the Subcontractor or Supplier to the applicable terms and conditions of the Contract Documents for the benefit of OWNER and ENGINEER. Whenever any such agreement is with a Subcontractor or Supplier who is listed as an additional insured on the property insurance provided in paragraph 5.06, the agreement between the CONTRACTOR and the Subcontractor or Supplier will contain provisions whereby the Subcontractor or Supplier waives all rights against OWNER, CONTRACTOR, ENGINEER, ENGINEER's Consultants, and all other individuals or entities identified in the Supplementary Conditions. to be listf!d as insureds or additional insureds (and the officers, directors, partners, emplcyees, agents, and other consultants and subcontractors of each and any of them) for all losses and damages caused by, arising out of, relating to, or resulting from any of the perils or causes of loss covered by such policies and any other property insurance applicable to the Work. If the insurers on any such policies. require separate waiver forms to be signed by any Subcontractor or Supplier,CONTRAC- TOR will obtain the same. 6.07 Patent Fees and Royalties A. CONTRACTOR shall pay all license fees and royalties and assume all costs incident to the use in the performance of the Work or the incorporation in the Work of any invention, design, process, product, or device which is the subject of patent rights or copyrights held by others. If a particular invention, design, process, product, or device is specified in the Contract Documents for use in the performance of the Work and if to the actual knowledge of OWNER or ENGINEER its use is subject to patent rights or copyrights calling for the payment of any license fee or royal ty to others, the existence of such rights shall be disclosed by OWNER in the Contract Documents. To the fullest extent permitted by Laws and Regulations, CONTRACTOR shall indemnify ..and hold harmless OWNER, ENGINEER, ENGINEER's Consultants, and the officers, directors, partners, employees or agents, and other consultants of each and any of them from and against all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to any infringement of patent rights or copyrights incident to the use in the performance of the Work or resulting from the incorporation in the Work of any invention, design, process, product, or device not specified in the Contract Documents. 6.08 Permits A. Unless otherwise provided in the Supplementary Conditions, CONTRACTOR shall obtain and pay for all construction permits and licenses. OWNER shall assist CONTRACTOR, when necessary, in obtaining such permits 00700 - 21 and licenses. CONTRACTOR shall- pay all governmental charges and inspection fees necessary for the prosecution of the Work which are applicable at the time of opening of Bids, or, if there are no Bids, on the Effective Date of the Agreement. CONTRACTOR shall pay all charges of utility owners for connections to the Work, and OWNER shall pay all charges of such utility owners for capital costs related thereto, such as plant investment fees. 6.09 Laws and Regulations A. CONTRACTOR shall give all notices and comply with all Laws and Regulations applicable to the performance of the Work. Except where otherwise expressly required by applicable Laws and Regulations, neither OWNER nor ENGINEER shall be responsible for monitoring CONTRACTOR's compliance with any Laws or Regulations. B. If CONTRACTOR performs any Work knowing or having re~on to know that it is contrary to Laws or Regulations, CONTRACTOR shall bear all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such Work; however, it shall not be CONTRACTOR's primary responsibility to make certain that the Specifications and Drawings are in accordance with Laws and Regulations, but this shall not relieve CONTRACTOR of CONTRACTOR's obligations under paragraph 3.03. C. Changes in Laws or Regulations not known at the time of .opening of Bids (or, on the Effective Date of the Agreement if there were no Bids ) having an effect on the cost or time of performance of the Work may be the subject of an adjustment in Contract Price or Contract Times. If OWNER and CONTRACTOR are unable to agree on entitlement to or on the amo~t or extent, if any, of any such adjustment, a Claim may be made therefor as provided in paragraph 10.05. 6.10 Taxes A. CONTRACTOR shall pay all sales, consumer, use, and other similar taxes required to be paid by CONTRAC- TOR in accordance with the Laws and Regulations of the place of the Project which are applicable during the performance of the Work. 6.11 Use of Site and Other Areas A. Limitation on Use of Site and Other Areas 1. CONTRACTOR shall confme construction equipment, the storage of materials and equipment, and the operations of workers to the Site and other areas permitted by Laws and Regulations, and shall not 00700 - 22 unreasonably encumber the Site and other areas with construction equipment or other materials or equipment. CONTRACTOR shall assume full responsibility for any damage to any such land or are~, or to the owner or occupant thereof, or of any adjacent land or areas resulting from the performance of the Work. 2. Should any claim be made by any such owner or occupant because of the performance of the Work, CONTRACTOR shall promptly settle with such other party by negotiation or otherwise resolve the claim by arbitration or other dispute resolutiQJl proceeding or at law. ., 3. To the fullest extent permitted by Laws and Regulations, CONTRACTOR shall indemnify and hold harmless OWNER, ENGINEER, ENGINEER's Consultant, and the officers, directors, partners, employees, agents, and other consultants of each and any of them from and against all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to any claim or action, legal or equitable, brought by any such owner or occupant against OWNER, ENGINEER, or any other party indemnified hereunder to the extent caused by or based upon CONTRACTOR's performance of the Work. B.

These record documents together with all approved Samples and a counterpart of all approved Shop Drawings will be available to ENGINEER for reference. Upon completion of the Work, these record documents, Samples, and Shop Drawings will be delivered to ENGINEER for OWNER. 6.13 Safety and Protection A. CONTRACTOR shall be solely responsible for initiating, maintaining and supervising all safety precautions and programs in connection with the Work. CONTRACTOR shall take all necessary precautions for the safety of, and shall provide the necessary protection to prevent damage, injury or loss to: 1. all persons on the Site or who may be affected by the Work; 2. all the Work and materials and equipment to be incorporated therein, whether in storage on or off the Site; and 3. other property at the Site or adjacent thereto, including trees, shrubs, lawns, walks, pavements, roadways, structures, utilities ,and Underground Facilities not designated for removal, relocation, or replacement in the course of construction. B.CONTRACTOR shall comply with all applicable Laws and Regulations relating to the safety of-persons or property, or to the protection of persons or property from damage, injury, or loss; and shall erect and maintain all necessary safeguards for such safety and protection.

Losses and damages (~d related expenses) caused by damage to the Work, not compensated by insurance or otherwise, sustained by CONTRACTOR in connection with the perfor- mance of the Work (except losses and damages within the deductible amounts of property insurance established in accordance with paragraph 5.06.0), provided such losses and damages have resulted from causes other than th~., negligence of CONTRACTOR, any Subcontractor, or anyone directly or indirectly employed by any of them or for whose acts any of them may be liable. Such losses shall include settlements made with the written consent and approval of OWNER. No such losses, damages, and expenses shall..be included in the Cost of the Work for the purpose of determining CONTRACTOR's fee. g. The cost of utilities, fuel, and sanitary facilities at the Site. h. Minor expenses such as telegrams, long distance telephone calls, telephone service at the Site, expressage, and similar petty cash items in connection with the Work. i. When the Cost of the Work is used to determine the value of a Change Order or of a Claim, the cost of premiums for additional Bonds and insurance required because of the changes in the Work or caused by the event giving rise to the Claim. j. When all the Work is performed on the basis of cost-plus, the costs of premiums for all Bonds and insurance CONTRACTOR is required by the Contract Documents to purchase and maintain. B. Costs Excluded: The term Cost of the Work shall not include any of the following items: 1. Payroll costs and other compensation of CONTRACTOR's officers, executives, principals (of partners~ips and sole proprietorships), general manag- ers, engineers, architects, estimators, attorneys, audi- tors, accountants, purchasing and contracting ~gents, expediters, timekeepers, clerks, and other personnel employed by CONTRACTOR, whether at the Site or in CONTRACTOR's principal or branch office for general administration of the Work and not specifically included in the agreed upon schedule of job classifications referred to in paragraph 11.01.A.l or specifically covered by paragraph 11.01.A.4, all of which are to be considered administrative costs covered by the CONTRACTOR's fee. 2.

C. CONTRAcrOR's Fee: When all the Work is performed on the basis of cost-plus, CONTRACTOR's fee shall be determined as set forth in the Agreement. When the value of any Work covered by a Change Order or when a Claim for an adjustment in Contract Price is determined on the basis of Cost of the Work, CONTRACTOR's fee shall be determined as set forth in paragraph 12.01. C. D. Documentation.. Whenever the Cost of the Work for any purpose is to be determined pursuant to paragraphs Il.OI.A and Il.Ol.B, CONTRACTOR will establish and maintain' records thereof in accordance with generally accepted accounting practices and submit in a form acceptable to ENGINEER an itemized cost breakdown together with supportirig data. 11.02 Cash Allowances A. It is understood that CONTRACTOR has included in the Contract Price all allowances so named in the Contract Documents and shall cause the Work so covered to be performed- for such sums as may be acceptable to OWNER and ENGINEER. CONTRACTOR agrees that: 1. the allowances include the cost to CONTRAC- TOR (less any applicable trade discounts) of materials and equipment required by the allowances to be delivered at the Site, and all applicable taxes; and 2. CONTRACTOR's costs for unloading and handling on the Site, labor, installation costs, overhead, profit, and other expenses contemplated for the allow- 00700 - 32 I ances have been included in the Contract Price and not in the allowances, and no demand for additional payment on account of any of the foregoing will be valid. I I B. Prior to fmal payment, an appropriate Change Order will be issued as recommended by ENGINEER to reflect actual amounts due CONTRACTOR on account of Work covered by allowances, and the Contract Price shall be correspondingly adjusted. I 11.03 Unit Price Work I II A. Where the Contract Documents provide that all or p~rt of the Work is to be Unit Price Work, initially the Contract Price will be deemed to include for ~all Unit Price Work an amount equal to the sum of the unit price for each separately identified item of Unit Price Work times the estimated quantity of each item as indicated in the Agree- ment. The estimated quantities of items of Unit Price Work are not guaranteed and are solely for the purpose of comparison of Bids and determining an initial Contract Price. Determinations of the actual quantities and classifications of Unit Price Work performed by CONTRACTOR will be made by ENGINEER subject to the provisions of paragraph 9.08. I I I I B. Each unit price will be deemed to include an amount considered by CONTRACTOR to be adequate to cover CONTRACTOR's overhead and profit for each separately identified item. I <;:. OWNER or CONTRACTOR may make a Claim for an adjustment in the Contract Price in accordance with paragraph 10.05 if: I I 1. the quantity of any item of Unit Price Work performed by CONTRACTOR differs materially and significantly from the estimated quantity of such item indicated in the Agreement; and I I 2. there is no corresponding adjustment with respect any other item of Work; and 3. if CONTRACTOR believes that CONTRACTOR is entitled to an increase in Contract Price as a result of having incurred additional expense or OWNER believes that OWNER is entitled to a decrease in Contract Price and the parties are unable to agree as to the amount of any such increase or decreaseA I I I I I I I ARTICLE 12 - CHANGE.OF CONTRACT PRICE; CHANGE OF CONTRACT TIMES I I 12.01 Change of Contract Price I A. The Contract Price may only be changed by a Change Order or by a Written Amendment. Any Claim for an adjustment in the Contract Price shall be based on written notice submitted by the party making the Claim to the ENGINEER and the other party to the Contract in accor- dance with the provisions of paragraph 10.05. I I B. The value of any Work covered by a Change Order or of any Claim for an adjustment in the Contract Price will be determined as follows: 1. where the Work involved is covered by unit prices contained in the Contract Documents, by applica- tion of such unit prices to the quantities of the items involved (subject to the provisions of paragraph 11.03 ); or I I 2. where the Work involved is not covered by unit prices contained in the Contract Documents, by a mutually agreed lump sum (which may include an allowance for overhead and profit.~ not necessarily in accordance with paragraph 12.01.C.2); or I I 3. where the Work involved is not covered by unit prices contained in the Contract Documents and agree- ment to a lump sum is not reached under paragraph 12.01.B.2, on the basis of the Cost of the Work (determined as provided in paragraph 11.01) plus a CONTRACTOR's fee for overhead and profit (deter- mined as provided in paragraph 12.0l.C). I I I C. CONFRAcrOR's Fee: The CONTRACTOR's fee for overhead and profit shall.be determined as follows: 1. a mutually acceptable fixed fee; or I I I I I 2. if a fiXed fee is not agreed upon, then a fee based on the following percentages of the various portions of the Cost of the Work: a. for costs incurred under paragraphs 11.0I.A.I and 11.0I.A.2, the CONTRACTOR's fee shall be 15 percent; b. for costs incurred under paragraph ll.01.A.3, the CONTRACTOR's fee shall be five percent; c. where one or more tiers. of subcontracts are on the basis of Cost of the Wark plus a fee and no fixed fee is agreed upon, the intent of paragraph 12.01. C. 2. a is that the Subcontractor who actually performs the Work, at whatever ti~r, will be paid a fee of 15 percent of the costs incurred by such Subcontractor under paragraphs 1I.Ol.A.I and 11 .01. A. 2 and that any higher tier Subcontractor and CONTRACTOR will each be paid a fee of five percent of the amount paid to the next lower tier Subcontractor; d. . no fee shall be payable on the basis of'costs itemized under paragraphs 11.01.i.M..4, 11.Ol.A.5, and I1.0l.B; ., e. the amount of credit to be allowed by CONTRACTOR to OWNER for any change which results in a net decrease in cost will be the amount of the actual net decrease in cost plus a. deduction in CONTRACTOR's fee by an amount equal to five percent of such net decrease; and f. when both additions and credits are in- volved in anyone change, the adjustment in CONTRACTOR's fee shall be computed on the basis of the net change in accordance with para- graphs 12.01.C.2.a through 12.0I.C.2.e, inclu- sive. 12.02 Change of Contract Times A. The Contract Times (or Milestones) may only be changed by a Change Order or by a Written Amendment. Any Claim for an adjustment in the Contract Times (or Milestones) shall be based on written notice submitted by the party making the claim to the ENGINEER and the 'other party to the Contract in accordance with the provisions of paragraph 10.05. B. Any adjustment of the Contract Times (or Milestones) covered by a Change Order or of any Claim for an adjustment in the Contract Times (or Milestones) will be determined in accordance with the provisions of this Article 12. 12.03 Delays Beyond CONFRACI'OR's Control A. Where CONTRACTOR is prevented from completing any part of the Work within the Contract Times - (or Milestones) due to delay beyond the control of CONTRACTOR, the Contract Times (or Milestones) will be extended in an amount equal to the time lost due to such delay if a Claim is made therefor as provided in paragraph 12.02.A. Delays beyond the control of CONTRACTOR shall include, but not be limited to, acts or neglect by OWNER, acts or neglect of utility owners or other contractors performing other work as contemplated-by 00700 - 33 Article 7 , fires, floods, epidemics, abnormal weather conditions, or acts of God. 12.04 Delays Within CONTRACTOR's Control A. The Contract Times (or Milestones) will not be extended due to delays within the control of CONTRACTOR. Delays attributable to and within the control of a Subcontractor or Supplier shall be deemed to be delays within the control of CONTRACTOR. 12.05 Delays Beyond OWNER's and CONTRACTOR's Control A. Where CONTRACTOR is prevented from complet- ing any part of the Work within the Contract Times (or Milestones) due to delay beyond the control of both OWNER and CONTRACTOR, an extension of the Contract Times (or Milestones) in an amount equal to the time lost due to such delay shall be CONTRACTOR's sole and exclusive remedy for such delay. 12.06 Delay Damages A. In no event shall OWNER or ENGINEER be liable to CONTRACTOR, any Subcontractor, any Supplier, or any other person or organization, or to any surety for or employee or agent of any of them, for damages arising out of or resulting from: 1. delays caused by or within the control of CON- TRACTOR; or 2. delays beyond the control of both OWNER and CONTRACTOR including but not limited to fires, floods, epidemics, abnormal weather conditions, acts of God, or acts or neglect by utility owners or other contractors performing other work as contemplated by Article 7. B. Nothing in this paragraph 12.06 bars a change in Contract Price pursuant to this Article 12 to compensate CONTRACTOR due to delay, interference, or disruption directly attributable to actions or inactions of OWNER or anyone for whom OWNER is responsible. ARTICLE 13 -TESTS AND INSPECTIONS; CORRECTION, REMOVAL OR ACCEPTANCE OF DEFECTIVE WORK 13.01 Notice of Defects A. Prompt notice of all defective Work of which OWNER or ENGINEER has actual knowledge will be given 00700 - 34 to CONTRACTOR. All defective Work may be rejected, corrected, or accepted as provided in this Article 13. 13.02 Access to Work A. OWNER, ENGINEER, ENGINEER's Consultants, other representatives and personnel of OWNER, independent testing laboratories, and governmental agencies with jurisdictional interests will have access to the Site and the Work at reasonable times for their observation, inspecting, and testing. CONTRACTOR shall provide them proper and safe conditions for such access an4' advise them of CONTRACTOR's Site safety procedures and programs so that they may comply therewith as applicable. ., 13.03 Tests and Inspections A. CONTRACTOR shall give ENGINEER timely notice of readiness of the Work for all required inspections, tests, or approvals and shall cooperate with inspection and testing personnel to facilitate required inspections or tests. B. OWNER shall employ and pay for the services of an independent testing laboratory to perform all inspec~ions, tests, or approvals required by the Contract Documents except: 1. for inspections, tests, or approvals covered by paragraphs 13.03. C and 13.03. D below; 2. that costs incurred in connection with tests or 41spections conducted pursuant to paragraph 13.04.B shall be paid as provided in said paragraph 13.04.B; and 3. as otherwise specifically provided in the Con- tract Documents. C. If Laws. or Regulations of any public body having jurisdiction require any Work (or part thereot) specifically to be inspected, tested, or approved by an employee or other representative of such public body, CONTRACTOR shall assume full responsibility for arranging and obtaining such inspections, tests, or approvals, pay all costs in connection therewith, and furnish ENGINEER the required certificates of inspection or approval. D. CONTRACTOR shall be responsible for arranging and obtaining and shall pay all costs in connection with any inspections, tests, or approvals required for OWNER's and ENGINEER's acceptance of materials or equipment to be incorporated in the Work; or acceptance of materials, mix designs, or equipment submitted for approval prior to CONTRACTOR's purchase thereof for incorporation in the Work. Such inspections, tests, or approvals shall be performed by organizations acceptable to OWNER and ENGINEER. I I I I I I I I I ,I I I I I I I I I I I Ii E. If any Work (or the work of 'others) that is to be inspected, tested, or approved is covered by CONTRACTOR without written concurrence of ENGINEER, it must, if requested by ENGINEER, be uncovered for observation. I F. Uncovering Work as provided in paragraph 13.03.E shall be at CONTRACTOR's expense unless CON- TRACTOR has given ENGINEER timely notice of CONTRACTOR's intention to cover the same and ENGI- NEER has not acted with reasonable promptness in response to such notice. I I 13.04 Uncovering Work I I A. If any Work is covered contrary to the written request of ENGINEER, it must, if requested by ENGINEER, be uncovered for ENGINEER's observation and replaced at CONTRACTOR's expense. I B. If ENGINEER considers it necessary or advisable that covered Work be observed by ENGINEER or inspected or tested by others, CONTRACTOR, at ENGINEER's request, shall uncover, expose, or otherwise make available for observation, inspection, or testing as ENGINEER may require, . that portion of the Work in question, furnishing all necessary labor, material, and' equipment. If it is found that such Work is defective, CONTRACTOR shall pay all Claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such uncovering, exposure, observation, inspection, and testing, and of satisfactory replacement or reconstruction (including but not limited to all costs of repair or replacement of work of others); and OWNER shall be entitled to an appropriate decrease in the Contract Price. If the parties are unable to agree as to the amount thereof, OWNER may make a Claim therefor as provided in paragraph 10.05. If, however, such Work is not found to be defective, CONT~CTOR shall be allowed an increase in the Contract Price or an extension of the Contract Times (or Milestones), or both, directly attribut- able to such uncovering, exposure, observation, inspection, testing, replacement, and reconstruction. If the parties are unable to agree as to the amount or extent thereof, CONTRACTOR may make a Claim therefor as provided in paragraph 10.05. I I~',......./~~ - ./ ......... I I I I I I 13.05 OWNER May Stop the Work I A. If the Work is defective, or CONTRACTOR fails to supply sufficient skilled workers or suitable materials or equipment, or fails to perform the Work in such a way that the completed Work will conform to the Contract Documents, OWNER may order CONTRACTOR to stop the Work, or any portion thereof, until the cause for such order has been eliminated; however, this right'of OWNER to stop I I the Work shall not give rise to any duty on the part of OWNER to exercise this right for the benefit . of CONTRACTOR, any Subcontractor, any Supplier, any other individual or entity, or any surety for, or employee or agent of any of them. 13.06 Correction or Removal of Defective Work A. CONTRACTOR shall correct all defective Work, whether or not fabricated, installed, or completed, or, if the Work has been rejected by ENGINEER, remove it from the Project and replace it with Work that is not defective. CONTRACTOR shall pay all 'Claims, ic~sts, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or removal (including but not limited to all costs of repair or replacement of work of others). 13.07 Correction Period A. If within one year after the date of Substantial Completion or such longer period of time as may be prescribed by Laws or Regulations or by the terms of any applicable special guarantee required by the Contract Documents or by any specific provision of the Contract Documents, any Work is found to be defective, or if the repair of any damages to the land or areas made available for CONTRACTOR's use by OWNER or permitted by Laws and Regulations as contemplated in paragraph 6. 11. A is found to be defective, CONTRACTOR shall promptly, without cost to OWNER and in accordance with OWNER's written instructions: (i) repair such defective land or areas, or (ii) correct such defective Work or, if the defective Work has been rejected by OWNER, remove it from the Project and replace it with Work that is not defective, and (iii) satisfac- torily correct or repair or remove and replace any damage to other Work, to the work of others or other land or areas resulting therefrom. If CONTRACTOR does not promptly comply with the terms of such instructions, or in an emergency where delay would cause serious risk of loss or damage, OWNER may have the defective Work corrected or repaired or may have the rejected Work removed and replaced, and all Claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or repair or such removal and replacement (including but not limited) to all costs of repair or replacement of work of others) will be paid by CONTRACTOR. B. In special circumstances where a particular item of equipment is placed in continuous service before Substantial Completion of all the Work, the correction period for that 00700 - 35 item may start to run from an earlier "date if so provided in the Specifications or by Written Amendment. c. Where defective Work (and damage to other Work resulting therefrom) has been corrected or removed and replaced under this paragraph 13.07, the correction period hereunder with respect to such Work will be extended for an additional period of one ye~ after such correction or removal and replacement has been satisfactorily completed. D. CONTRACTOR's obligations under this paragraph 13.07 are in addition to any other obligation or warranty. The provisions of this paragraph 13.07 shall not be construed as a substitute for or a waiver of the provisions of any applicable statute of limitation or repose. 13.08 Acceptance of Defective Work A. If, instead of requiring correction or removal and replacement of defective Work, OWNER (and, prior to ENGINEER's recommendation of final payment, ENGINEER) prefers to accept it, OWNER may do so. CONTRACTOR shall pay all Claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) attributable to OWNER's evaluation of and determination to accept such defective Work (such costs to be approved by ENGINEER as to reasonableness) and the diminished value of the Work to the extent not otherwise paid by CONTRACTOR pursuant to this sentence. If any such acceptance occurs prior to ENGINEER's recommendation of fmal payment, a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work, and OWNER shall be entitled to an appropriate decrease in the Contract Price, reflecting the diminished . value of Work so accepted. If the parties are unable to agree as to the amount thereof, OWNER may make a Claim therefor as provided in paragraph 10.05. If the acceptance occurs after such recommendation, an appropriate amount will be paid by CONTRACTOR to OWNER. 13.09 OWNER May Correct Defective Work A. If CONTRACTOR fails within a reasonable time after written notice from ENGINEER to correct defective Work or to remove and replace rejected Work as required by ENGINEER in accordance with paragraph 13.06.A, or if CONTRACTOR fails to perform the Work in accordance with the Contract Documents, or if CONTRACTOR fails to comply with any other provision of the Contract Documents, OWNER may, after seven days written notice to CONTRACTOR, correct and remedy any such deficiency. B. In exercising the. rights and remedies under this paragraph, OWNER shall proceed expeditiously. In I connection with such corrective and remedial action, OWNER may exclude CONTRACTOR from all or part of the Site, take possession of all or part of the Work and suspend CONTRACTOR's services . related thereto,. take possession of CONTRACTOR's tools, appliances, con- struction equipment and machinery at the Site, and incorpo- rate in the Work all materials and equipment stored at the Site or for which OWNER has paid CONTRACTOR but which are stored elsewhere. . CONTRACTOR shall allow OWNER, OWNER's representatives, agents and employees, OWNER's other contractors, and ENGINEER and ENGINEER's Consultants access to ,tIfe Site to enable OWNER to exercise the rights and remedies under this parflgraph. I I I I I I c. All Claims, costs, losses, and damages (including but not. limited to. all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) incurred or sustained by OWNER in exercising the rights and remedies under this paragraph 13.09 will be charged against CON- TRACTOR, and a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work; and OWNER shall be entitled to an appropriate decrease in the Contract Price. If the parties are unable to agree as to the amount of the adjustment, OWNER may make a Claim therefor as provided in paragraph 10.05. Such claims, costs, losses and damages will include but not be limited to all costs of repair, or replacement of work of others destroyed or damaged by correction, removal, or replacement of CONTRACTOR's defective Work. I I I I D. CONTRACTOR shall not be allowed an extension of the Contract Times (or Milestones) because of any delay in the performance of the Work attributable to the exercise by OWNER of OWNER's rights and remedies under this - paragraph 13.09. I I I ARTICLE 14 - PAYMENTS TO CONTRACTOR AND COMPLETION 14.01 Schedule of Values I A. The schedule of values established as provided in paragraph 2.07.A will serve as the basis for progress payments and will be incorporated into a form of Application for Payment acceptable to ENGINEER. Progress payments on account of Unit Price Work will be based on the number of units completed. I I I 00700 - 36 I I I 14.02 Progress Payments A. Applications for Payments I 1. At least 20 days before the date established for each progress payment (but not more often than once a month), CONTRACTOR shall submit to ENGINEER for review an Application for Payment filled out and signed by CONTRACTOR covering the Work completed as of the date of the Application and accompanied by such supporting documentation as is required by the Contract Documents. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the Site or at another location agreed to in writing, the Application for Payment shall also be accompanied by a bill of sale, invoice, or other docu- mentation warranting that OWNER has received the materials and equipment free and clear of all Liens and evidence that the materials and equipment are covered by appropriate property insurance or other . arrangements to protect OWNER's interest therein, . all of which must be satisfactory to OWNER. I I I I I I 2. Beginning with the second Application for Payment, each Application shall include an affidavit of CONTRACTOR stating that all previous progress payments received on account. of the Work have been applied on account to discharge CONTRACTOR's legitimate obligations associated with prior Applications for Payment. I I I 3. The amount of retainage with respect to pro- gress payments will be as stipulated in.the Agreement. B. Review of Applications I I 1. ENGINEER will, within 10 days after receipt of each Application for Payment, . either indicate in writing a recommendation of payment and present the Application to OWNER or return the Application to CONTRACTOR indicating in writing ENGINEER's reasons for refusing to recommend payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit. the Application. I I 2. ENGINEER's recommendation of any payment requested in anh~Application for Payment will constitute a representation by ENGINEER to OWNER, based on ENGINEER's observations on the Site of the executed Work as an experienced and qualified design profession- al and on ENGINEER's review of the Application for Payment and the accompanying data and schedules, that to the best of ENGINEER's knowledge, information and belief: I I I 00700 - 37 a. the Work has progressed to the point indicated; b. the quality of the Work is generally in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a fmal determination of quantities and classifications for Unit Price Work under paragraph 9.08, and to any other qualifications stated in the recommendation); and . i' c. the conditions precedent to ., CONTRACTOR's being entitled to such payment appear to have been fulfilled in so far as it is ENGINEER's responsibility to observe the Work. 3. By recommending any such payment ENGI- NEER will not thereby be deemed to have represented that: (i) inspections made to check the quality or the quantity of the Work as it has been performed have been exhaustive, extended to every aspect of the Work in progress, or involved detailed inspections of the Work beyond the responsibilities specifically assigned to ENGINEER in the Contract Documents; or (ii) that there may not be other matters or issues between the parties that might entitle CONTRACTOR to be paid additionally by OWNER or entitle OWNER to withhold payment to CONTRACTOR. 4. Neither ENGINEER's review of CONTRACTOR's Work for the purposes of recom- mending payments nor ENGINEER's recommendation of any payment, including fmal payment, will impose responsibility on ENGINEER to supervise, direct, or control the Work or for the means, methods, techniques, sequences, or procedures of construction, or the safety precautions and programs incident thereto, or for CON- TRACTOR's failure to comply with Laws and Regu- lations applicable to CONTRACTOR's performance of the Work. Additionally, said review or recommendation will not impose responsibility on ENGINEER to make any examination to ascertain how or. for what purposes CONTRACTOR has used the moneys paid on account of the Contract Price, or to determine that title to any of the Work, materials, or equipment has passed to OWNER free and clear of any Liens. 5. ENGINEER may refuse to recommeIid the whole or any part of any payment if, in ENGINEER's opinion, it would be incorrect to make the representa- tions to OWNER referred to in paragraph 14.02.B.2. ENGINEER may also refuse to recommend any such payment or, because of subsequently discovered evidence or the results of subsequent inspections or tests, revise or revoke any such payment recommendation previously made, to such extent as may be necessary in ENGINEER's opinion to protect OWNER from loss because: a. the Work is defective, or completed Work has been damaged, requiring correction or replace- ment; b. the Contract Price has been reduced by Written Amendment or Change Orders; c. OWNER has been required to correct defective Work or complete Work in accordance with paragraph 13.09; or d. ENGINEER has actual knowledge of the occurrence of any of the events enumerated in para- graph 15.02.A. "if C. Payment Becomes Due 1. Ten days after presentation of the Application for Payment to OWNER with ENGINEER's recom- mendation, the amount recommended will (subject to the provisions of paragraph 14.02.D) become due, and when due will be paid by OWNER to CONTRACTOR. D. Reduction in Payment 1. OWNER may refuse to make payment of the full amount recommended by ENGINEER.because: a. claims have been made against OWNER on account of CONTRACTOR's performance or fur- nishing of the Work; b. Liens have been filed in connection with the Work, except where CONTRACTOR has delivered a specific Bond satisfactory to OWNER to secure the satisfaction and discharge of such Liens; c. there are other items entitling OWNER to a set-off against the amount recommended; or d. OWNER has actual knowledge of the occur- rence of any of the events enumerated in paragraphs. 14.02.B~5.a through 14.02.B.5.c or paragraph 15.02.A. 2. If OWNER refuses to make payment of the full amount recommended by ENGINEER, OWNER must give CONTRACTOR immediate written notice (with a copy to ENGINEER) stating the reasons for such action and promptly pay . CONTRACTOR - any amount remaining after deduction of the amount so withheld. OWNER shall promptly pay CONTRACTOR the amount so withheld, or any adjustment thereto agreed to by OWNER and CONTRACTOR, when CONTRAC- TOR corrects to OWNER's satisfaction the reasons for such action. I I I 3. If it is subsequently determined that OWNER's refusal of payment was not justified, the amount wrongfully withheld shall be treated as an amount due as determined by paragraph 14.02. C .1. I I 14.03 CONTRACIOR's Warranty ofTjtle , A. CONTRACTOR warrants and guarantees that title to '~l Work, materials, and equipment covered by any Application for Payment, whether incorporated in the Project or not, will pass to OWNER no later than the time of payment free and clear of all Liens. I I 14.04 Substantial Completion I A. When CONTRACTOR considers the entire Work ready for its intended use CONTRACTOR shall notify OWNER and ENGINEER in writing that the entire Work is substantially complete (except for items specifically listed by CONTRACTOR as incomplete) and request that ENGINEER issue a certificate of Substantial Completion. Promptly thereafter, OWNER CONTRACTOR, and ENGINEER shall make an inspection of the Work to determine the status of completion. If ENGINEER does not consider the Work substantially complete, ENGINEER will notify CONTRACTOR in writing giving the reasons therefor. If ENGINEER considers the Work substantially complete, ENGINEER will prepare and deliver to OWNER a tentative certificate of Substantial Completion which shall fIX the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before fmal payment. OWNER shall have seven days after receipt of the tentative certificate during which to make written objection to ENGINEER as to any provisions of the certificate or attached list. If, after considering such objections, ENGINEER concludes that the Work is not substantially complete, ENGINEER will within 14 days after submission of the tentative certificate to OWNER notify CONTRACTOR in writing, stating the reasons therefor. If, after consideration of OWNER's objections,- ENGINEER considers th~ Work substantially complete, ENGINEER will within said 14 days execute and deliver to OWNER and CONTRACTOR a defInitive certificate of Substantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as ENGINEER believes justified after consideration of any objections from OWNER. At the time of delivery of the tentative certificate of Substantial Comple- tion ENGINEER will deliver to OWNER and CONTRAC- TOR a written recommendation as to division of responsibili- I I I I I I I I I I 00700 - 38 I I I ties pending fmal payment between OWNER and CONTRACTOR with respect to security, operation, safety, and protection of the Work, maintenance, heat, utilities, insurance, and warranties and guarantees. Unless OWNER and CONTRACTOR agree otherwise in writing and so inform ENGINEER in writing prior to ENGINEER's issuing the defInitive certificate of Substantial Completion, ENGINEER's aforesaid recommendation will be binding on OWNER and CONTRACTOR until fmal payment. I I I B. OWNER shall have the right to exclude CONTRACTOR from the Site after the date of Substantial Completion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. I I 14.05 Panial Utilization A. Use by OWNER at OWNER's option of any substantially completed part of the Work which has specifically been identified in the Contract Documents, or which OWNER, ENGINEER, and CONTRACTOR agree constitutes a separately functioning and usable part of the Work that can be used by OWNER for its intended purpose without significant interference with CONTRACTOR's performance of the remainder of the Work, may be accomplished prior to Substantial Completion of all the Work subject to the following conditions. I I I I 1. OWNER at any time may request CON- TRACTOR in writing to permit OWNER to use any such part of the Work which OWNER believes to be ready for its intended use and substantially complete. If CONTRACTOR agrees that such part of the Work is substantially complete, CONTRACTOR will certify to OWNER and ENGINEER that such part of the Work is substantially complete and request ENGINEER to issue a certificate of Substantial Completion for. that part of the Work. CONTRACTOR at any time may notify OWNER and ENGINEER in' writing that CONTRACTOR considers any such part of the Work ready for its intended use and substantially complete and request ENGINEER to issue a certificate of Substantial Completion for that part of the Work. Within a reasonable time ..after either such request, OWNER, CONTRACTOR, and ENGINEER shall make an inspection of that part of the Work to determine its status of completion. If ENGINEER does not consider that part of the Work to be substantially complete, ENGINEER will notify OWNER and CONTRACTOR in writing giving the reasons therefor.

Thirty days after the presentation to OWNER of the Application for Payment and accompanying docu- mentation, the amount recommended by ENGINEER will become due and, when due, will be paid by OWN- ER to CONTRACTOR. 14.08 Final Completion Delayed A. If, through no fault of CONTRACTOR, [mal completion of the Work is significantly delayed, and if ENGINEER so confmns, OWNER shall, upon receipt of CONTRACTOR's fmal Application for Payment and recommendation of ENGINEER, and without terminating the Agreement, make payment of the balance, due for that portion of the Work fully completed and accepted. If the remaining balance to be held by OWNER for Work not fully completed or corrected is less than the retainage stipulated. in the Agreement, and if Bonds have been furnished as required in paragraph 5.01, the written consent of the surety to the payment of the balance due for that portion of the Work fully completed and accepted shall be submitted by CON- TRACTOR to ENGINEER with the Application for such payment. Such payment shall be made under the terms and conditions governing fmal payment, except that it shall not constitute a waiver of Claims. 14.09 Waiver of Claims A. The making and acceptance offmal payment will constitute: 00700 - 40 1. a waiver of all Claims by OWNER against CONTRACTOR, except Claims arising from unsettled Liens, from defective Work appearing after fmal inspection pursuant to paragraph 14.06, from failure to comply with the Contract Docunients or the terms of any special guarantees specified therein, or from CONTRACTOR's continuing obligations under the Contract Documents; and 1 1 1 1 1 1 1 1 2. a waiver of all Claims by CONTRACTOR against OWNER other than those previously made in writing which are still unsettled. j' ~TICLE 15 - SUSPENSION OF WORK AND TERMINA TION 15.01 OWNER May Suspend Work A. At any time and without cause, OWNER may suspend the Work or any portion thereof for a period of not more than 90 consecutive days by notice in writing to CON- TRACTOR and ENGINEER which will fIX the date on which Work willbe resumed. CONTRACTOR shall resume the Work on the date so fIXed. CONTRACTOR shall be allowed an adjustment in the Contract Price or an extension of the Contract .Times, or both, directly attributable to any such suspension if CONTRACTOR makes a Claim therefor as provided in paragraph 10.05. 1 -I 1 1 1 1 1 15.02 OWNER May Terminatefor Cause A. The occurrence of anyone or more of the following events will justify termination for cause: 1. CONTRACTOR's persistent failure to perform the Work in accordance with the . Contract Documents (including,. but not limited to, failure to supply sufficient skilled workers or suitable materials or equipment or failure to adhere to the progress schedule established under paragraph 2.07 as adjusted from time to time pursuant to paragraph 6.04); 2. CONTRACTOR's disregard of Laws or Regulations of any public body having jurisdiction; 3. CONTRACTOR's disregard of the authority of ENGINEER; or 1 1 I I 4. CONTRACTOR's violation in any substantial way of any provisions of the Contract Documents. B. If one or more of.the events identified in paragraph 15.02.A occur, OWNER may, after giving CONTRACTOR (and the surety, if any) seven days written notice, terminate I I the services of CONTRACTOR, exclude CONTRACTOR from the Site, and take possession of the Work and of all CONTRACTOR's tools, appliances, construction equipment, and machinery at the Site, and use the same to the full extent they could be used by CONTRACTOR (without liability to CONTRACTOR for trespass or conversion)" incorporate in the Work all materials and equipment stored at the Site or for which OWNER has paid CONTRACTOR but which are stored elsewhere, and fInish the Work as OWNER may deem expedient. In such case, CONTRACTOR shall not be entitled to receive any further payment until the Work is finished. If the unpaid balance of the Contract Price exceeds all claims ,costs , losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by OWNER arising out of or relating to completing the Work, such excess will be paid to CONTRACTOR. If such claims, costs, losses, and damages exceed such .unpaid balance, CONTRACTOR shall pay the difference to OWNER. Such claims, costs, losses, and damages incurred by OWNER will be reviewed by ENGINEER as to their reasonableness and, when so approved by ENGINEER, incorporated in a Change Order. When exercising any rights or remedies. under this paragraph OWNER shall not be required to obtain the lowest price for the Work performed. I I I I-H- I I I I C. Where CONTRACTOR's services have been so (erminated by OWNER, the termination will not affect any rights or remedies of OWNER against CONTRACTOR then existing or which may thereafter accrue. Any retention or payment of moneys due CONTRACTOR by OWNER will not release CONTRACTOR from liability. I I 15.03 OWNER May Terminate For Convenience I I I A. Upon seven days written notice to CONTRACTOR- and ENGINEER, OWNER may, without cause and without prejudice to any other right or remedy of OWNER, elect to terminate the Contract. In such case, CONTRACTOR shall be paid (without duplication of any items): 1. for completed and acceptable Work executed in accordance with the Contract Documents prior to the effective date of termination, including fair and reasonable sums for overhead and profit on such Work; I 2. for expenses sustained prior to the effective date of termination in performing services and furnishing labor, materials, or equipment as required by the Contract Documents in connection with uncomplete~ Work, plus fair and reasonable sums for overhead and profit on such expenses; I I 3. for all claims, costs, loss~s, and damages (including but not limited to all fees and charges of I engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) incurred in settlement of terminated contracts with Subcontractors, Suppliers, and ~thers; and 4. for reasonable expenses directly attributable to termination. B. CONTRACTOR shall not be paid on account of loss of anticipated profits or revenue or other economic loss arising out of or resulting from such termination. ,i . 15.04 CONTRACTOR May Stop Work or Terminate ., A. If, through no act or fault of CONTRACTOR, the Work is suspended for more than 90 consecutive days by OWNER or under an order of court or other public authority, or ENGINEER fails to act on any Application for Payment within 30 days after it is submitted, or OWNER fails for 30 days to pay CONTRACTOR any sum fmally determined to be due, then CONTRACTOR may, upon seven days written notice to OWNER and ENGINEER, and provided OWNER or ENGINEER do not remedy such suspension or failure within that time, terminate the Contract and recover from OWNER payment on the same terms as provided in paragraph 15.03. In lieu of terminating the Contract and without prejudice to any other right or remedy, if ENGI- NEER has failed to act on an Application for Payment within 30 days after it is submitted, or OWNER has failed for 30 days to pay CONTRACTOR any sum fmally determined to be due, CONTRACTOR may, seven days after written notice to OWNER and ENGINEER, stop the Work until payment is made of all such amounts due CONTRACTOR, including interest thereon. The provisions of this paragraph 15.04 are not intended to preclude CONTRACTOR from making a Claim under paragraph 10.05 for an adjustment in Contract Price or Contract Times or otherwise for expenses or damage directly attributable to CONTRACTOR's stopping the Work as permitted by this paragraph. ARTICLE 16 - DISPUTE RESOLUTION 16.01 Methods and Procedures A. Dispute resolution methods and procedures, if any, shall be as set forth in the Supplementary Conditions. If no method and procedure has been set forth, and subject to the provisions of paragraphs 9.09 and 10.05, OWNER and ,CONTRACTOR may exercise such rights or remedies as either may otherwise have under the Contract Documents or by Laws or Regulations in respect of any dispute. 00700 - 41 17.02 Computation of Times ., I I I I iit I I I I I :-,1 I I I I I I I I I ARTICLE 17 - MISCELLANEOUS 17 .01 Giving Notice A.

Should a separate contractor cause damage to the work or property of Contractor or should the performance of work by any separate contractor at the si te give rise to any other claim, Contractor shall not institute any action, legal or equitable, against Owner, Engineer or the Construction Coordinator or permit any action against any of them to be maintained and continued in its name or for its benefit in any court or before any arbiter which seeks to impose liability on or to recover damages from Owner, Engineer or the Construction Coordinator on account of any such damage or claim. If Contractor is delayed at any time in performing or furnishing work by any act or neglect of a separate contractor and Owner and Contractor are unable to agree as to the extent of any adjustment in contract time attributable thereto, Contractor may make a claim for an extension .of time in accordance wi th Article 12 of the General Conditions. An .extension of the contract time shall be Contrac- tor's exclusive remedy with respect to Owner, Engineer and Construction Coordinator for any delay, disruption, interference or hinderance caused by any separate contractor.

Supp. 5 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 7.0 ENGINEER'S STATUS DURING PERFORMANCE OF THE WORK (GC-9) This section is a supplement to Article 9--Engineer's status During Construction of the General Conditions. A. Owner's Consultant The Engineer, as the design professional, will be the Owner's consultant during the performance of the work. The duties and responsibilities and the limitations of authority of the Engineer as the Owner's consultant during this period are set forth in these Contract Documents and will not be extended without written consent of the Owner and the Engineer. In the event of an extension of the Engineer's duties and responsi- bilities, the Contractor will be provided with written notice of such amendment. B. Role as Interpreter The Engineer will be the initial interpreter of the terms and condi tions of the Contract Documents and the judge of the performance thereunder. All matters re.lating to the execution and progress of the work, or the interpretation of or performance under the Contract Documents, shall be referred initially to the Engineer for decision which will be rendered promptly. The Engineer will issue such written interpretation of the Contract Documents (in the form of drawings or otherwise) as he may determine necessary which will be consistent with or reason,ably inferable from the overall intent of the Contract Documents. C. Communications with Contractor All communications with the Contractor pertaining to perfor- mance of the work will normally be issued through the Engineer. D. Resident Project Inspector The Resident Project Inspector will be either the Engineer or the Engineer's agent, as so designated. The Resident Proj ect Inspector is responsible for assisting the Project Engineer in determining, in general, if the work is completed in accordance with the plans and specifications and Contract Documents. Communications pertaining to compliance submittals, written interpretations, and amendments shall be directed to the Engineer at his home office with copies to the Resident Project Inspector. Communications pertaining to day-to-day operations at the site shall be directed to the Resident Project Inspector. E. Authority to Disapprove or Reject Defective Work All equipment and materials used and all work done with at all times will be subject to the inspection, tests, and approval of the Engineer or his authorized representatives. Supp. 6 The Engineer has the authority to disapprove or reject any work which is "defective". He also has the authority to require special inspection or testing of the work. The Engineer has the authori ty to disapprove or rej ect any defective workmanship, equipment or materials. If the work is defective or the Contractor fails to supply sufficient skilled workmen or suitable equipment or materials, the Engineer may order the Contractor to stop the work or any portion thereof until the' cause for such order has been eliminated; however, this right of the Engineer to stop the work will not give rise to any duty on the part of the EngineeJ. to exercise this right for the benefit of the Contractor or any other party. F. Limitations on Engineer's Responsibilities This article states the limitations on the Engineer's responsi- bility as between the Engineer and the Contractor. Neither Engineer's authority to act under these Contract Documents nor any decision made by him in good faith either to exercise or not exercise such authority will give rise to any duty or responsibility of the Engineer to the Contractor, any Subcontractor, supplier or manufacturer, any of their agents or employees, or any other person performing any of the work. The Engineer is not responsible for construction, safety precautions, and programs incidental thereto. Nei ther is he responsible for the Contractor's failure to perform the work in accordance with the Contract Documents. The Engineer is not responsible for the acts or omissions of any Contractor or any Subcontractor, Contractor's supplier or manufacturer, or any of his or their agents or employees. The presence or absence of the Engineer or his representative will not relieve the Contractor of any responsibility or of any guarantee of his performance. Neither will observation by the Engineer or his representative in any way be understood to relieve the Contractor of any responsibili ty for proper supervision of the work at all times. The review and acceptance of the Contractor's compliance submittals by the Engineer will be understood to be only for conformance wi th the design concept, for compliance wi th the intent of the Contract Documents, and to assist the Contractor in interpreting the Contract Documents, so as to preclude delivery of the equipment or materials not acceptable for the work. The Engineer's acceptance of compliance submittals will not place upon him any responsibility for any deviations from the requirements of the Contract Documents unless the Contrac- tor has in writing called the Engineer' 5 attention to such Supp. 7 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I deviation at the time of the submission and the Engineer has given. written concurrence on the specific deviation. Such deviations will be included in a contract amendment. G. Engineer's Pay Estimates Any Engineer's pay estimate will constitute a representation by the Engineer to the Owner that work has progressed to the extent indicated. To the best of his knowledge, the quality of the work is in accordance with the Contract Documents, and the Contractor is enti tIed to payment of the amount shown in the Engineer's pay estimate. Rendering the Engineer's pay estimate is not an approval of the qual i ty or quanti ty of the work, the means or methods of construction, or the monetary methods used by the Contractor. The Engineer may refuse to render an Engineer's pay estimate for the whole or any part of any payment if, in his opinion, it would be an incorrect representation to the Owner. 8.0 CORRECTION PERIOD (GC-~l..3 ..07) The correction period identified in paragraph 13.12 of the General Conditions is hereby amended to call for a two (2) year correction period, which shall commence after completion and acceptance of all the work identif~ed in the plans and specifications. All other requirements of paragraph 13.12 shall remain in effect. 9.0 UNIT PRICE WORK (GC-11.03) Add the following paragraph: "11 · 9. 4 If the actual quanti tyof a uni t-priced i tern varies more than 15% above or below the estimated quantity, an equitable adjustment in the contract price shall be negotiated upon demand of either the Owner or the Contractor. The equitable adjustment shall be based upon any increase or decrease in costs due solely to the variation above 115% or below 85% of the estimated quantity." 10.0 APPLICATION FOR PROGRESS PAYMENT (GC-14.02) Change the last sentence to read as follows: "The Owner shall retain five (5%) percent of the amount of each payment until final completion and acceptance of all works covered by the Contract Documents." 11. o LIEN WAIVERS (GC- 14.02) The Contractor shall furnish partial or complete lien waivers along with each payment request. The lien waivers shall be submitted by the Contractor, all subcontractors, and all material suppliers on the project. No payment will be authorized unless the lien waivers are received. Supp. 8 12.0 STATE OF MINNESOTA WITHHOLDING REQUIREMENTS (GC-14.07.A2) The Contractor and all subcontractors shall submit state form IC-134, "Wi thholding Affidavi t for Contractors" along with the final payment request. No payment will be authorized unless the IC-134 forms are received. The Contractor shall also be aware of Minnesota statute 290.9705 regarding out-of-state contractors. Forms may be obtained from the Minnesota Department of Revenue, Busines Trust Tax Division. 13.0 ARBITRATION (GC-16) Add the following paragraph: 16.6 "The Contractor will carryon the work and maintain the progress schedule during any arbitration proceedings, unless otherwise mutually agreed in writing." 14.0 FAILURE TO COMPLETE WORK ON TIME (GC-12.04) Should the Contractor fail to complete the work on or before the original date (s) set forth for completion in paragraph 1 of the Special Provisions or on or before the corrected date as granted by extension of time for completion, the Owner may perrni t the Contractor to proceed, and in such case, there shall be deducted from any monies due or that may become due the Contractor, the sum of $250.00 per day for each and every calendar day, exclusive of Sundays and holidays, that the work shall remain uncompleted. This sum shall be considered and treated, not as a penalty, but as the cost of field and office Engineering and Inspections and Liquidated Damages. Permitting the Contractor to continue and finish the work or any part of it after the time fixed for its completion, or after date to which the time of completion may have been extended, shall in no way operate as a waiver on the part of the Owner, or as a waiver of any of his rights under the contract. Nei ther by the taking over of the work by the Owner nor by the termination of the contract shall the Owner forfeit the right to recover liquidated damages from the Contractor or his surety for failure to complete the contract.

T est rolling shall be performed prior to, intermittently during, and after completion of subgrade preparation (2112) or sub grade excavation work (2105) when ordered by the En~ineer. The limits of yielding or rutting portion of this Specification 2111.3 shall apply only to the test roll for final acceptance of the sub grade preparation; earlier test rolling shall be for the purpose of identifying those areas needing sub grade excavation, etc. Later test rolling on the aggregate base course shall be to determine if required stability and density exists. The "required stability" shall be such that when test rolled, the surface shows yielding or rutting of no more than 1 ~" measured from the top of the constructed grade to the bottom of the rut. The "required density" shall be 1000/0 Standard Proctor. I I I In embankment/fill areas, the sub grade may be test rolled at an elevation lower than finished subgrade elevation if the condition of the soils being placed indicate that normal subgrade preparation (2112) cannot be performed and that sub grade excavation (2105) may be necessary; this procedure is to eliminate having to remove materials just previously placed. Test rolling shall also be used in conjunction with the placing of aggregate or bituminous base courses when ordered by the Engineer. The sub grade shall pass the test rolling prior to placement of the aggregate base and the aggregate base shall pass the test rolling prior to placement of the curbing or bituminous base. I I B. The Contractor will furnish a wheel loader (with operator) or other equipment approved by the Engineer for test rolling.

Under no circumstances shall subbase material be hauled until the subgrade has been approved by the Engineer with respect to grade and density. I 2.06 SUBGRADE EXCAVATION (2105) Subgrade excavation shall consist of all excavations made below the top 12" of the subgrade surface of the road and between the shoulder slopes, which are not made for the purpose of obtaining topsoil, and the materials of which are not classified for payment such as rock excavation. This work shall include the removal and disposal of unsuitable materials in the roadbed and replacing such materials with common excavation, common borrow, granular borrow, or base materials, together with any other work necessary to provide drainage for the excavations. Subgrade excavation shall be made to the depths and location indicated by the Engineer. Areas of sub grade excavation may be required at random locations throughout the roadbed or may be required as a "core-type excavation", wherein the roadbed is excavated for its entire length and width. No subgrade excavation shall be done I I I I 3 I I I prior to attempting subgrade preparation, sub grade soil removal (top 12"), and test rolling. I All excavation shall be by the load and haul method, in an attempt not to disturb the already questionable stability of the virgin soils below the sub-cut. Common excavation, common borrow, granular borrow, or base materials, when used in replacing materials removed through subgrade excavation, shall be as follows: I A. Common Excavation Material (210S.2A) Common excavation material to be used in subgrade excavation must be approved by the Engineer prior to placing. When this material is used, the Contractor shall be paid for both excavation of the unsuitable materials and replacement of the unsuitable materials with common excavation, at the common excavation unit. price, provided the common excavation. material is. furnished from an initial excavation area. If the common excavation material has been moved once initially and stockpiled, then the material will be. paid as common borrow material, as described below. The excavation and replacement~are.both paid through the unit bid price of the material used for replacement. I I I B. Common Borrow Material (2105B) When suitable or ample common excavation material cannot be found within the excavation limits, the common borrow material approved by the Engineer will be used in sub grade excavation. Borrow material will be obtained within the right-of-way if available; it not, it may be obtained off the right-of-way at a location located and negotiated by the Contractor and Engineer. Regardless of the location of the borrow source, only one bid item will apply for furnishing of the borrow. When common borrow is used, the Contractor shall be paid for both excavation of the unsuitable materials and replacement of the unsuitable materials with common borrow, at the common excavation unit price. The excavation and replacement are both paid through the unit bid price of the material used for replacement. I I I C. Granular Borrow Material (3149) When common excavation or common borrow material cannot be obtained by the contractor on or off the right-of-way, the Engineer may direct the Contractor to use granular borrow material for sub grade excavation. I I When granular borrow is used, the contractor shall be paid for both replacement of the unsuitable materials and. excavation of the unsuitable materials. with~ granular borrow at the granular borrow unit price. The excavation and replacement.are both paid through the unit bid price of the material used for replacement. I All materials used for replacement in areas of sub grade excavation shall be compacted in accordance with 2105, as previously mentioned in Section 2.03. I Payment for sub grade excavation shall be by the original in-place cubic yard (c.y.) and shall be compensation for excavation, disposal of the material, and placement of suitable soils at material unit cost. I INCLEMENT ;WEATHER: No subgrade excavation shall be used to correct .conditions caused by inclement weather. In cases. where inclement. weather is continuous and for long periods of time, and does not allow for expeditious completion of sub grade preparation by use of 2112, 2105, and! or Section 2.05, the Engineer may require the Contractor to prepare the roadways as follows: I A. Make a core excavation of the sub grade to a depth as directed by the Engineer. I B. Replace the excavated material below subgrade with the same materials to be used for base material (Class 5 etc.) and then immediately continue to place the loose material in the area above the subgrade elevation. The sub grade excavation and the base course both shall be constructed with base material in a fashion which will contribute to "bridging". In this case, after the sub grade excavation has been made and I I 4 I the conditions do not allow for compaction, then the bottom of the sub grade excavation shall be subcut to a uniform bottom and the base material shall be placed in a fashion to prevent pumping of intrusion of the subgrade into the base material. Generally, the first 12 inches of the material shall be deposited on the sub grade before any rolling or compaction begins. All compaction done in this situation shall be by use of static equipment. I I C. When this procedure for subgrade excavation is used, the Contractor shall be paid for excavating the unsuitable materials below sub grade elevation and shall be paid for all base materials used above and below sub grade elevation, all at contract unit price; the compaction of this base material shall be considered incidental. Also, when this method is used, the Contractor shall not .be paid for sub grade preparation (2112). I I : Base. material used Jorhackfill,as described. above for, "bridging" ,will be paid for. at the same unit · price paid under the applicable base price and unit. I Any over-excavated areas shall be returned to the proper grade and cross-section by the Contractor at no additional cost to the Owner. I 2.07 EXCESS MATERIAL Excess material not used on the project is the property of the Owner and shall~ be disposed of as directed by the Engineer. Disposal of the excess material shall be incidental to the excavation unit price and project.

I I I I I I I I I I I I I I 9 I I I I I I I I I I I I I I I I I I I I CONCRETE SPECIFICA TIONS DESCRIPTION Curb or combined curbs and gutters, sidewalks and driveway aprons, shall consist of air-entrained portland cement concrete constructed on a prepared sub grade in accordance with these specifications. This work shall be in reasonable cost conformity with the lines and grades, thicknesses, and typical cross sections shown on the Plans or established by the Engineer. All work shall be performed in accordance with MnDOT Specifications. All curb not conforming to the design as specified on the Plans is to be removed and replace9, ,t no cost to the Owner. Type B curb is to be placed at all curb returns with a minimum 10' transition to other curb types. ., CONCRETE The air-entrained portland cement concrete shall meet the requirements of MnDOT Specification 2461. The component parts shall be batched by weight, in proportions, to produce a concrete developing a minimum compressive strength of 3900 psi in 28 days. Concrete mix shall be mixture 3A32 for hand placement and 3A22 for machine placement, per MnDOT Specification 2461. A design mix shall be submitted to the Engineer for approval prior to installation. Any addition of excess water, as determined by the Engineer, to the concrete during placement, will result in removal and replacement of affected material. BASE PREPARATION The base shall be a minimum thickness of 6 inches of Class 5 gravel under all curb and gutter and all driveway aprons. A minimum base thickness of 4 inches of pit run sand shall be placed beneath all sidewalks. The base shall be compacted and shall extend a minimum of one foot outside the curb and drives and 0.5 feet outside sidewalk forms. The base shall be reasonably dense, firm, trimmed to a uniform smooth surface and in a moist condition when the concrete is placed. MACHINE PLACEMENT The slipform! extrusion machine approved shall be so designed as to place, spread, consolidate, screed, and finish the concrete in one complete pass ip. such a manner that a minimum of hand finishing will be necessary to provide a dense and homogeneous concrete section. The machine shall shape, vibrate, and! or extrude the concrete for the full width and depth of the concrete section being placed. It shall be operated with as nearly a continuous forward movement as possible. All operations of mixing, delivery, and spreading concrete shall be so coordinated as to provide uniform progress, with stopping and starting of the machine held to a minimum. FORMED METHOD The forms shall be of wood, metal, or other suitable material that is straight and free from warp, having sufficient strength to resist the pressure of the concrete without displacement, and sufficient tightness to prevent the leakage of mortar. Flexible or rigid forms of proper curvature may be used for curves having a radiusj of 100 feet or less. Division plates shall be metal. 1 The front and back forms shall extend for the full depth of the concrete. All of the forms shall be braced and staked so that they remain in both horizontal and vertical alignment until their removal. They shall be cleaned and coated with an approved form-release agent before concrete is placed against them. - The concrete shall be deposited into the forms without segregation and then it shall be tamped and spaded or mechanically vibrated for thorough consolidation. Low roll or mountable curbs may be formed without the use of a face form by using a straightedge and templet to form the curb face. When used, face forms shall be removed as soon as possible to permit finishing. Front and back forms shall be removed without damage to the concrete after it has set. It FINISHING ~I The plastic concrete shall be finished smooth, if necessary, by means of a wood float and then it shall be given a final surface texture using a light broom or burlap drag. Concrete that is adjacent to forms and formed joints shall be edged with a suitable edging tool to the dimension shown on the plans. JOINTING Contraction Joints Transverse, weakened-plane, contraction joints shall be constructed at right angles to the curb line at intervals not exceeding 15 feet in the curb and 5-feet squares in the sidewalk. Joint depth shall average at least 1A of the cross section of the concrete. Contraction joints may be sawed, hand-formed, or made by l/S inch-thick division plates in the formwork. Sawing shall be done early after the concrete has set to prevent the formation of uncontrolled cracking. The joints may be hand-formed either by (1) using a narrow or triangular jointing tool or a thin metal blade to impress a plane or weakness into the plastic concrete, or (2) inserting l/S-inch-thick steel strips into the plastic concrete temporarily. Steel strips shall be withdrawn before final finishing of the concrete. .Where division. plates are used to make contraction joints, the plates shall be removed after the concrete has set and while the forms are still in place. Expansion Joints Expansion joints shall be constructed at right angles to the curb line at 300' maximum intervals, at immovable structures and at points of curvature for short-radius curves. Filler material for expansion joints shall conform to requirements of ASTM D994, D1751, or D1752 and shall be furnished in a single 3/4-inch-thick piece for the full depth and width of the joint. Expansion joints in a slipformed curb or curb and gutter shall be constructed with an appropriate hand tool by raking or sawing through partially set concrete for the full depth and width of the section. The cut shall be only wide enough to permit a snug fit for the joint filler. After the filler is placed, open areas adjacent to the filler shall be filled with concrete and then trowelled and edged. Alternatively, an expansion joint may be installed by removing a short section of freshly extrud€d curb and gutter immediately, installing temporary holding forms, placing the expansion joint filler, and replacing and reconsolidating the concrete that was removed. Contaminated concrete shall be discarded. I I I I I I I I I I I I I I I 2 I I I I I I I I I I I I I I I I I I I I I I I Other Joints Construction joints may be either butt- or expansion-type joints. Curbs or combined curbs and gutters constructed adjacent to existing concrete shall have the same type of joints as in the existing concrete, with similar spacing; however, contraction joint spacing shall not exceed 15 feet. Curbing placed in conjunction with concrete paving shall be jointed according to the type of joint indicated on the Plan and Profile. Reinforcing Steel The Contractor shall install two (2) No.4 steel reinforcing bars, twenty feet in length, across each service trench or any other trench which crosses the curbing. Two (2) No.4 steel reinforcing bars four feet ill length shall be installed at all transitions from machine placed versus hand placed curbing. Reinforcing cages to be installed behind the catch basin castings shall conform to detail 4.017 h. Protection The Contractor shall always have material available to protect the surface of the plastic concrete against rain. These materials shall consist of waterproof paper or plastic sheeting. For slipform construction, materials such as wood planks or forms to protect the edges shall also be required When concrete is being placed in cold weather, and the temperature may be expected to drop below 350 F, suitable protection shall be provided to keep the concrete from freezing until it is at least 10 days old. Concrete injured by frost action shall be removed and replaced at the Contractor's expense. Curing Concrete shall be cured for at least three days after placement to protect it against loss of moisture, rapid temperature change, and mechanical injury. Moist burlap, waterproof paper, white polyethylene sheeting, white liquid membrane compound, or a combination thereof, may be used as the curing material. Membrane curing shall not be permitted in frost-affected areas when the concrete will be exposed to de-icing chemicals within 30 days after completion of the curing period. Backfilling After the concrete has set sufficiently, the spaces in front and back of curbs shall be refilled with suitable material to the required elevations. the fill material shall be thoroughly tamped in layers. It shall be the Contractor's responsibility to protect the curbing during all phases of the backfilling operation. Any curbing damaged during this process shall be removed and replaced at the Contractor's expense. Testing Not less than three test cylinders of standard size and manufacture shall be made for each 50 cubic yards of concrete placed, or for each day's operations unless otherwise directed by the Engineer. One cylinder from each set shall be tested at seven days and one cylinder at 28_days, in accordance with ASTM C-31. The third cylinder shall be retained as.a spare in case problems occur with either of the other two. Air entrainment and slump tests shall be taken on each load prior to placement. 3 To cast the cylinders, fill the molds in three. equal layers and uniformly rod each layer 25 times with a bullet- nosed rod. When rodding the second and third layers, the rod should just break through into the layer beneath. The molds should be filled continuously and without interruption. After rodding the top layer, tap the cylinder lightly to close any voids that might exist, and cover immediately to prevent loss of moisture. Be sure the cylinders are on a level surface during curing and that the tops are smooth and level to ensure minimum laboratory preparation and the best test results. T est results indicating concrete substandard from the above requirements shall be reason for halting concreting operations and investigation of the cause of the deficiency, and removal and replacement of concrete placed during the period represented by the test, if, in the opinion of the Engineer, such action is necessary to protect the structural integrity of the construction. i i All testing shall be done at the Contractor's expense by an' approved testing laboratory. Test results shall be submitted once a week to the Engineer. 4 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I .'

F Granular Materials Granular materials furnished for foundation, bedding, encasement, backfill, or other purposes as may be specified shall consist of any natural or synthetic mineral aggregate such as sand, gravel, crushed rock, crushed stone, or slag, that shall be so graded as to meet the gradation requirements specified herein for each particular use. Fl Granular Material Gradation Classifications Granular materials furnished for use in Foundation, Bedding, Encasement, or Backfill construction shall conform to the following requirements: Percent Passing Sieve Size 3 Inch 2 Inch 1 Inch 3/4 Inch 3/8 Inch No. 4 No. 10 No. 40 No. 200 Foundation Material Use Designation Bedding Encasement Backfill 100 100 100 85-100 90-100 90-100 30- 60 50- 90 50- 90 0- 10 35-' 80 35- 80 35-100 20- 65 20- 65 20-100 0- 35 0- 35 0- 35 0- 10 a- la a- la 100 NOTE: Granular foundation, bedding and encasement material provi- ded for plastic pipe and fi ttings shall meet the require- ments of ASTM 2321, Class I, II or III materials or the requirements provided above if the Engineer authorized such substitution. F2 Granular Material Use Designations Granular materials provided for Foundation, Bedding, Encasement, or Backfi 11 use as required by the Plans, Specifications and Special Provisions, ei ther as part of the pipe item work unit or as a separate Contract Item, shall be classified as to use in accordance wi th the following: - 50 - Material Use Designation Zone Designation Granular Foundation -------- Placed below the bottom of pipe grade as replacement for unsui t- able or unstable soils, to achieve better foundation support. Granular Bedding ----------- Placed below the pipe midpoint, prior to pipe installation, to facilitate proper shaping and to achieve uniform pipe support. Granular Encasement -------- Placed below an elevation one foot above the top of pipe, after pipe installation, for protection of the pipe and to assure proper filling of voids or thorough consolidation of backfill. Granular Backfill ---------- Placed below the surface base course, ,if any, as the second stage of backfill, to minimize trench settlement and provide support for surface improvements. In each case above, unless otherwise indicated, the lower limits of any particular zone shall be the top surface of the next lower course as constructed. The upper limi ts of each zone are established to define variable needs for material gradation and compaction or void content, taking into consideration the sequence of con- struction and other conditions. The material use and zone designations described above shall only serve to fulfill the objectives and shall not be construed to restrict the use of any particular material in other zones where the gradation requirements are met. G Pi.ling Piling shall be constructed in accordance with provi- sions of MnDOT Specification 2452. H Insulation Main insulation shall be extruded rigid board material having a thermal conductivity of 0.23 BTU/hour/square foot/degree Fahrenheit/per inch thickness, maximum, at 400F mean, a compressive strength of 35 psi minimum, and water absorption of 0.25 percent by volume maximum. Unless otherwise specified in the Plans, Specifications, and Special Provisions, board dimensions shall measure 8' long, 2' or 4' wide, and 1" or It" thick. - 51 - I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 2621.3 CONSTRUCTION REQUIREMENTS A General Provisions Al Maintenance of Traffic Whenever work interferes with the flow of traffic along a roadway, the Gontractor shall provide for traffic control and signing artd public safety in accordance with the provisions of Appendix B of the Minnesota Manual of Uniform Traffic Control devices and MnDOT Specifications 1404 and 1710, and the Special Provisions. Neither road closures nor detours shall be permitted unless specified in the Special Provisions or authorized by the Engineer. Where road closures or detours are permi tted by the Engineer, the Engineer shall determine the appropriate agencies, boards, or departments the Contractor must notify prior to taking the action and the proper advance notice to be provided to each body. Compliance with this requirement shall not be construed to relieve the Contractor from the responsibility of notifying agencies or institutions whose services may be predicated upon a roadway being opened to traffic or whose services would be hindered if a roadway is closed to traffic. Such agencies or institutions shall include, but not be limited to, the police department, the fire department, municipal bus service, school bus service, and ambulance service. The Contractor shall keep the required agencies inf9rmed of changing traffic patterns and detour situations. A2 Establishing Line and Grade. In locations where the sewer is in direct conflict with existing watermain and water services, the watermain and water services shall be lowered to provide at least 18 inches of vertical distance between the top of the watermain or service and the bottom of the sani tary sewer or relocated in accordance with Plans. When local conditions prevent a vertical separation as described, the following construction shall be used: a vertical separation of at least 18 inches between the bottom of the sewer and the top of the watermain; adequate structural support for the sewers to prevent excessive deflection of joints and settling on and breaking of the watermains; that the length of water pipe be centered at the point of crossing so that the joints will be equidistant and as far as possible from the sewer. - 52 - - 53 - I I I I I I I I I I I I I I I I I I I Watermains shall be laid at least 10 feet horizontally from any sani tary sewer, storm sewer or sewer manhole, whenever possible. When local conditions prevent a horizon- tal separation of 10 feet, a watermain may be laid closer to a storm or sanitary sewer provided that: (1) The bottom of the watermain is at least 18 inches above the top of the sewer; (2) Where this vertical separation cannot be obtained, the sewer shall be constructed of materials and with joints that are equivalent to watermain standards of construction and shal~ be pressure tested to assure water tightness prior to backfilling. The primary line and grade will be established by the Engineer. For trench installation, line and grade stakes will be set parallel to the proposed pipeline at an appropriate offset therefrom as will best serve the Contractor's operations wherever practical. For tunnel installation, line and grade stakes will be set directly above the proposed pipeline setting. Grade and line stakes will be set at 25-foot intervals along the pipeline; at each change in line or grade, and as needed for pipeline appurtenances. The Contractor shall arrange operations to avoid unnecessary interference with the establishment of the primary line and grade stakes, and shall render whatever assistance may be required by the Engineer in accomplishing the staking. The Contractor shall' be responsible for preservation of the primary stakes, and, if negligent in providing necessary protection, shall bear the full cost of any restaking. The Contractor shall be solely responsible for the correct transfer of the primary line and grade to all working points and for construction of the work to the prescribed lines and grades as established by the Engineer. Following construction of a work shaft on tunnel installa- tions, the line and grade shall be transferred down the shaft and be projected into and throughout the length of each tunnel heading. A3 Protection of Surface Structures All surface structures and features located outside the permissible excavation limits for underground installa- tions, together with those within the construction areas which are indicated in the Plans as being saved, shall be properly protected against damage and shall not be disturbed or removed wi thout approval of the Engineer. I I I I I I I I I I I I I I I I I I I Within the construction limits, as required, the removal of improvements such as paving, curbing, walks, turf, etc., shall be subject to acceptable replacement after completion of underground work, wi th all expense of removal and replacement being borne by the Contractor to the extent that separate cpmpensation is not specifically provided for in the Contract'~ Obstructions such as street signs, guard posts, small culverts, and other items of prefabricated construction may be temporarily removed during construction, provided that essential service is maintained in a relocated setting as approved by the Engineer and that nonessential i terns are properly stored for the duration of construction. Upon completion of the underground work, all such items shall be replaced in their proper setting at the sole expense of the Contractor. In the event of damage to any surface improvements, ei ther privately or publicly o.wned, in the absence of construction necessity, the Contractor will be required to replace or repair the damaged property to the satisfaction of the Engineer and without cost to the Owner. A4 Interference of Underground structures When any underground structure interferes with the, planned placement of the pipeline or appurtenances to such an extent that alterations in the work are necessary to el iminate the confl ict or avoid endangering effects on either the existing or proposed facilities, the Contractor shall immediately notify the Engineer and the Owner of the affected structure. When any existing facilities are endangered by the Contractor's operations, the Contractor shall cease work at the site and take such precautions as may be necessary to protect the inplace structures until a decision is made as to how the conflict will be resolved. Without specific authorization from the Engineer, no essential utility service shall be disrupted, nor shall any change be made in either the existing structures or the planned installations to overcome the interference. Altera- tions in existing facilities will be allowed only to the extent that service will not be curtailed unavoidably and then only when the encroachment or relocation will satisfy all applicable regulations and conditions. Wherever alterations are required as a result of unforeseen underground interferences not due to any fault or negligence of the Contractor, the Engineer will issue a written order covering any additional or extra work involved and specifying the revised basis of payment, if - 54 - - 55 - I I I I I I I I I I I I I I I I I I I any. Any alterations made strictly for the convenience of the Contractor shall be subject to prior approval and shall be at the Contractor's expense. No extra compensation will be allowed for delays caused by the interfer~nce of underground structures. AS Removal of Surface Improvements Removal of surface improvements in connection with trench excavation shall be limited to actual needs for installation of the pipeline and appurtenances, based on the allowable trench widths and any other controls imposed in connection wi th the work. Removal operations shall be coordinatedeffecti vely with the excavation and installa- tion operations as will cause the least practical disrup- tion of traffic or inconvenience to the public. The debris resulting from removals shall become the property of the Contractor and shall be disposed of by the Contractor. Removed debris shall not be deposi ted at locations that will block access to fire hydrants, private driveways, or other essential service areas, nor obstruct surface drainage. Removal and final disposal of debris shall be accomplished as a single operation wherever possible and, in any event, the debris shall be removed from the site before starting the excavating operations. Removal of concrete or bituminous structures shall be by methods of producing clean-cut breakage to prescored lines as will preserve the remaining structure without damage. Removal equipment shall not be operated in a manner that will cause damage to the remaining structure or adjoining property. Where not removed to an existing joint, concrete structures shall be sawed along the break lines to a minimum depth of one-third of the structure depth. Any reusable materials generated during the work, su.ch as aggregate, sod, or topsoil, shall be segregated from other waste materials and be stockpiled so as to maintain suitability and permit proper reuse. The use of drop weight equipment for breaking pavement will be allowed to the extent that the Contractor shall assume full responsibility for any damages caused thereby. The pavement breaking operations shall not be allowed to become a nuisance to the public or a source of damage to underground or adjacent structures. The Engineer reserves the right to order discontinuance of drop weight breaking operations at any time. I I I I I I I I I I I I I I I I I I I A6 Temporary Service Measures While any open excavations are maintained, the Contrac- tor shall have available a supply of steel plates suitable for temporary bridging of open trench sections where either vehicular or pedestrian traffic must be maintained. Use of the plates sharI be as directed or approved by the Engineer and where installed they shall be secured against possible displacement and be replaced with the permanent structure as soon as possible. B Excavation and Preparation of Trench B1 Operational Limitations and Requirements Excavating operations shall proceed only so far in advance of pipe laying as will satisfy the needs for coordination of work and permit advance verification of unobstructed line and grade as planned. Where interference with existing structures is possible or in any way indicated, and where necessary to establish elevation or direction for connections to inplace structures, the excavating shall be done at those locations in advance of the main operation so actual conditions will be exposed in sufficient time to make adjustments without resorting to extra work or unnecessary delay. All installations shall be accomplished by open trench construction except for short tunnel sections approved by the Engineer and with the exception that boring and jacking or tunnel construction methods shall be employed where so specifically required by the Plans, Specifications, or Special Provisions. Installation of pipe through tunnel excavations will be allowed only where the surface structure can be properly supported and the backfill restored to the satisfaction of the Engineer. The excavating operations shall be conducted so as to carefully expose all inplace underground structures without damage. Wherever the excavation extends under or approaches so close to an existing structure as to endanger it in any w~y, precautions and protective measures shall be taken as -necessary to preserve the st~cture and provide temporary support. Hand methods of excavating shall be utilized to probe for and expose such critical or hazardous installa- tions as gas pipe and power or communication cables. The Engineer shall be notified of any need for blasting to remove materials which cannot be broken up mechanically, and there shall be no blasting operations conducted until the Engineer's approval has been secured. Blasting will be allowed only when proper precautions are taken to protect - 56 - - 57 - I I I I I I I I I I I I I I I I I I I I ife and property, and then shall be restricted as the Engineer directs. The Contractor shall assume full respon- sibility for any damages caused by blasting, regardless of the requirements for notification and approval. The Contractor shall secure any required permits for blasting and shall conduct blasting operations in conformance with all applicable ~'state and local laws, regulations and ordinances. B2 Classification and Disposition of Materials Excavated materials will be classified for payment only to the extent that the removal of ~aterials classified by the Engineer as Rock will be paid for separately from other unclassified materials, either as a separate Contract Item or as an Extra Work Item when no bid price is applicable. No other materials encountered in the excavations, with the exception of i terns classified for payment as structure removals, will be considered as Unclassified Excavation, and unless otherwise specified in the Plans, Specifi- cations, and Special Provisions, no additional compensation shall be provided for their removal. Unclassified materials shall include muck, rubble, wood debris, and boulder stone, masonry or concrete fragments less than one cubic yard in volume, together with other miscellaneous matter that can be removed effectively with power operated excavators without resorting to drilling and blasting. Rock excavation shall be defined to include all hard, solid rock in ledge formation, bedded deposits and unstratified masses ; all natural conglomerate deposits so firmly cemented as to present all the characteristics of solid rock; and any boulder stone, masonry or concrete fragments exceeding one cubic yard in volume. Materials such as shale, hard pan, soft or disintegrated rock which can be dislodged with a hand pick or removed with a power operated excavator will not be classified as Rock Excava- tion. Excavated materials will be classified for reuse as being either Suitable or Unsuitable for backfill or other specified use, subject to selective controls. All suitable materials' shall be reserved for backfill to the extent needed, and any surplus remaining shall be utilized for other construction on the project as may be specified or ordered by the Engineer. To the extent pract_?-cable, granular materials and, topsoil shall be segregated from other materials during the excavating and stockpiling operations so as to permit best use of the available materials at the time of backfilling. Unless otherwise specified in the Plans, Specifications, and Special Provisions, material handling as described above shall be I I I I I I I I I I I I I I I I I I I considered incidental with no additional compensation provided therefor. All excavated materials reserved for backfill or other use on the project shall be stored at locations approved by the Engineer tha~ will cause a minimum of inconvenience to publ ictravel , ~'adj acent properties, and other special interests. The material shall not be deposited so close to the edges of the excavations as would create hazardous conditions, nor shall any material be placed so as to block the access to emergency services. All materials considered un sui table by the Engineer, for any use on the proj ect, shall be immediately removed from the project and be disposed of as arranged by the Contractor at no extra cost to the Contract. B3 Excavation Limitations and Requirements Trench excavating shall be to a depth that will permit preparation of the foundation as specified and installation of the pipeline and appurtenances at the prescribed line and grade, except where alterations are specifically authorized. Trench widths shall be sufficient to permit the pipe to be laid and joined properly and the backfill to be placed and compacted as specified. Extra width shall be provided as necessary to permi t convenient placement of sheeting and shoring and to accommodate placement of appurtenances. Excavations shall be extended .below the bottom of structure as necessary to accommodate any required Granular Foundation material. When rock or unstable foundation materials are encountered at the established grade, additional materials shall be removed as specified or ordered by the Engineer to produce an acceptable founda- tion. Unless otherwise indicated or directed, rock shall be removed to an elevation at least six inches below the bottom surface of the pipe barrel and below the lowest projection of joint hubs. All excavations below grade shall be to a minimum width to the outside pipe diameter plus two feet. Rock shall be removed to such additional horizontal dimensions as will provide a minimum clearance of six inches on all sides of appurtenant structures such as valves, housings, access structures, etc. Where no other grade controls are indicated or esta- blished for the pipeline, the excavating and fouildation preparations shall be such as to provide a minimum cover over the top of the pipe as specified. Trench widths shall allow for at least six inches of clearance on each side of the j oint hubs. The maximum allowable width of the trench - 58 - The proper Contractor shall assume full responsibility and adequate placement of sheeting, shoring, for and I I I I I I I I I I I I I I I I I I I at the top of pipe level shall be the outside diameter of the pipe plus two feet, subject to the considerations for alternate pipe loading set forth below. The width of the trench at the ground surface shall be held to a minimum to prevent unnecessary destruction of the surface structures. ~ The maximum a'llowable trench width at the level of the top of pipe may be exceeded only by approval of the Engineer, after consideration of pipe strength and loading relationships. Any alternate proposals made by the Contrac;.... tor shall be in writing, giving the pertinent soil weight data and proposed pipe strength alternate, at least seven days prior to the desired date of decision. Approval of alternate pipe designs shall be with the understanding that there will be no extra compensation allowed for any increase in material or construction costs. If the trench is excavated to a greater width than that authorized, the Engineer may direct the Contractor to provide a higher class of bedding and/or a higher strength pipe than that required by the Plans, Specifications, and Special Provisions in order to satisfy design requirements, without additional compensation. therefor. B4 Sheeting and Bracing Excavations All excavations shall be sheeted, shored, and braced as will meet all requirements of the applicable safety codes and regulations; comply wi th any specific requirements of the Contract; and prevent disturbance or settlement of adjacent surfaces, foundations, structures, utilities, and other properties. Any damage to. the work under contract or to adjacent structures or property caused by settlement, water or earth pressures, slides, cave-ins, or other causes due to failure or lack of sheeting, shoring, or bracing or through negligence or fault of the Contractor in any manner, shall be repaired at the Contractor's expense and without delay. Where conditions warrant extreme care, the Plans, Specifications, and Special Provisions may require special precautions to protect life or property, or the Engineer may order the installation of sheet piling of the interlocking type or direct that other safety measures be taken as deemed necessary. Failure of the Engineer to order correction of improper or inadequate sheeting, shoring, or bracing shall not relieve the Contractor's responsibilities for protection of life, property, and the work. - 59 - I I I I I I I I I I I I I I I I I I I bracing, wherever and to such depths that soil stabili ty may dictate the need for support to prevent displacement. Bracing shall be so arranged as to provide ample working space and so as not to place stress or strain on the inplace struc~res to ~y extent that may cause damage. ~ Sheeting, shoring and bracing materials shall be removed only when and in such manner as will assure adequate protection of the inplace structures and prevent displace- ment of supported grounds. Sheeting and bracing shall be left in place only as required by the Plans, Specifica- tions, and Special Provisions or ordered by the Engineer. Otherwise, sheeting and bracing may be removed as the backfilling reaches the level of respective support. Wherever sheeting ~d bracing is left in place, the upper portions shall be cut and removed to an elevation of three feet or more below the established surface grade as the Engineer may direct. All costs of ~rnishing, placing, ~d removing sheeting, shoring, and bracing materials, including the value of materials left in place as required by the Contract, shall be included in the prices bid for pipe installation and will not be compensated for separately. When any sheeting, shoring, or bracing materials are left in place by written order of the Engineer, in the absence of specific requirements of the Contract to do so,payrnent will be made for those materials as ~ Extra Work Item, including waste material resulting from upper cut-off requirements. B5 Preparation and Maintenance of Foundations Foundation preparations shall be conducted as necessary to produce a stable foundation and provide continuous and uniform pipe bearing between bell holes. The initial excavating or backfilling operations shall produce a - subgrade level slightly above finished grade as will permit hand shaping to finished grade by trimming of high spots and without the need for filling of low spots to grade. Final subgrade preparations shall be such as to produce a finished grade at the centerline of the pipe that is within O. 03 foot of a straight line between pipe joints and to provide bell hole excavation at each joint as will permit proper joining of pipe and fittings. In excavations made below grade to remove rock or unstable materials, the backfilling to grade shall be made with available suitable materials unless placement of Granular Foundation or Bedding material is specified and provided for or is ordered by the Engineer as an Extra Work Item. Placement of the backfill shall be in relatively - 60 - uniform layers not exceeding 8 inches in loose thickness. Each layer of backfill shall be compacted thoroughly, by means of approved mechanical compaction equipment, as will produce uniform pipe support throughout the full pipe length and facilitate proper shaping of the pipe bed. Where the foundation soil is found to consist of materials that the Engineer considers to be so unstable as to preclude removal and replacement to a reasonable depth to achieve solid support, a suitable foundation shall be constructed as the Engineer directs in the a"bsence of special requirements therefor in the Plans, Specifications, and Special Provisions. The Contractor may be required to furnish and drive piling and construct concrete or timber bearing supports or other work as may be provided for in an Extra Work order. Care shall be taken during final subgrade shaping to prevent any over-excavation. Should any low spots develop, they shall only be filled with approved material, which shall have optimum moisture content and be compacted thoroughly, without additional compensation provided to the Contractor. The finished subgrade shall be maintained free of water and shall not be disturbed d.uring pipe lowering . operations except as necessary to remove pipe slings. The discharge of trench dewatering pumps shall be directed to natural drainage channels or storm water drains. Draining trench water into sanitary sewers or combined sewers will not be permitted. The Contractor shall install and operate a dewatering system of wells or points to maintain pipe trenches free of water wherever necessary or as directed by the engineer to meet the intent of these specifications. Unless otherwise specified in the Plans, Specifications, and Special Provisions, such work shall be considered incidental with no additional compensation provided therefore. All costs of excavating below grade and placing foundation or bedding aggregates as required shall be included in the bid prices for pipe items to the extent that the need for such work is indicated in the Contract provisions and the Proposal does not provide for payment therefor under separate Contract Items. Any excavation below grade and any foundation or bedding aggregates required by order of the Engineer in the absence of Contract requirements therefor will be compensated for separately as Extra Work Items. If examination by the Engineer reveals that the need for placement of foundation aggregates was caused by the Contractor's manipulation of the soils in the presence of excessive moisture or lack of proper dewatering, the cost of the corrective measures shall be borne by the Contractor. - 6"1 - I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I C Installation of Pipe and Fittings Cl Inspection and Handling Proper and adequate implements, tools, and facilities satisfactory to the Engineer shall be provided and used by the Contractor ~or the safe and convenient prosecution of the work. During the process of unloading, all pipe and accessories shall be inspected by the Contractor for damage. The Contractor shall notify the Engineer of all material found to have cracks, flaws or other defects. The Engineer shall inspect the damaged materials and have the right to rej ect any materials found to be unsatisfactory. The Contractor shall promptly remove all rejected material from the site. All materials shall be handled carefully, as will prevent damage to protective coatings, linings, and joint fillings; preclude contamination of interior areas; and avoid jolting contact, dropping, or dumping. All work and materials are subject to tests by the Owner at such frequency as may be determined by the Engineer. Such tests shall be paid for by the Owner. Whi Ie suspended and before being lowered into laying posi tion, each pipe section and appurtenant uni t shall be inspected by the Contractor to detect damage or unsound conditions that may need corrective action or be cause for rejection. The Contractor shall inform the Engineer of any defects discovered and the Engineer will prescribe the required corrective actions or order rejection. Immediately before placement, the joint surfaces of each pipe section and fitting shall be inspected for the presence of foreign matter, coating blisters, rough edges or projections, and any imperfections so detected shall be corrected by cleaning, trimming, or repair as needed. C2 Pipe Laying Operations Trench excavation and bedding preparations shall proceed ahead of pipe placement as wi 11 permit proper laying and joining of the units at the prescribed grade and alignment without unnecessary deviation or hindrance. All foreign matter or dirt shall be removed from the inside of the pipe and fi ttings before they are lowered into position in the trench and they shall be kept clean by approved means during and after laying. The sewer materials shall be carefully lowered into laying position by the use of sui table restraining devices. Under no circumstances shall the pipe be dropped into the trench. - 62 - - 63 - I I I I I I I I I I I I I I I I I I I At the time of pipe placement, the bedding condi tions shall be such as to provide uniform and continuous support for the pipe between bell holes. Bell holes shall be excavated as necessary to make the joint connections, but they shall be no larger than would be adequate to support the pipe throughout its length. No pipe material shall be laid in water nor when the trench or bedding conditions are otherwise unsuitable or improper. When placement or handling precautions prove inadequate, in the Engineer's opinion, the Contractor shall provide and install suitable plugs or caps effectively closing the open ends of each pipe section before it is lowered into laying position, and they shall remain so covered until removal is necessary for connection of an adjoining unit. Unless otherwise permi tted by the Engineer, bell and spigot pipe shall be laid with the bell ends facing upgrade and the 'laying shall start on the downgrade end and proceed upgrade. As each length of bell and spigot pipe is placed in laying position, the spigot end shall be centered in the bell and the pipe forced home and brought to correct line and grade. The pipe shall be secured in place with approved backfill material, which shall be thoroughly compacted by tamping around the pipe to a height of at least 12 inches above the top with hand operated mechanical tamping devices or by hand. The joint areas shall remain exposed and precautions shall be taken to prevent the soil from entering the joint space, until the joint seal is effected. Backfill in the bell area shall be left loose. Connection of pipe to existing lines or previously constructed manholes or catch basins shall be accomplished as shown in the Plans or as otherwise approved by the Engineer. Where necessary to make satisfactory closure or produce the required curvature, grade or alignment deflec- tions at joints shall not exceed that which will assure tight joints and comply with any limitations recommended by the pipe manufacturer. Entrance of foreign matter into pipeline openings shall be prevented at all times to the extent that suitable plugs or covering can be kept in place over the openings without int~rfering with the installation operations. Installation of PVC, ABS, and composite truss pipe shall conform to ASTM D-2321. C3 Connection and Assembly of Joints All pipe and fitting joints shall fit tightly and be' I I I I I I I I I I I I I I I I I I I fully closed. Spigot ends shall be marked as necessary to indicate the point of complete closure. All joints shall be soil tight, as the minimum requirement, and shall be watertight in all sani tary sewer pipe lines and in all storm sewer pipe lines installed wi thin the limi ts of a paved street or highway traffic lanes. Where specified, the joints in cert~in assemblies shall be made structurally integral by being completely encased in concrete to form a rigid watertight unit as indicated in the standard drawings. Where watertight joints are required ,wi thout concrete encasement, the joints shall be sealed as follows, subject to such other approved method as the Engineer may authorize as being an acceptable alternative: (1) Concrete pipe and fitting joints--compression type rubber gasket seals conforming to the requirements of ASTM C-443, ASTM C-361 or AASHTO M-198 for circular pipe, or as otherwise approved by the Engineer in the case of non-circular pipe sections. (2) ABS/PVC Truss pipe, ABS solid wall pipe and fittings- assembled gasket seal joints. (3) Smooth wall and corrugated wall PVC pipe and fittings- assembled push-on gasketed joints shall pass perfor- mance tests as listed in ASTM D-3212 . Solvent welds shall not be permitted. (4 ) Vitrified clay pipe and fi ttings--factory fabricated compression seals or compression type couplings. ( 5) Corrugated steel pipe and fi ttings--sealed wi th approved type compression seals. Where watertight joints are not required, joints in concrete pipe shall be made soil tight by filling wi th mortar as the Engineer directs. Pipe joints encased in concrete will not have to be sealed with gasket type seals, but shall be filled with mortar as directed. C4 Bulkheading Open Pipe Ends All pipe and fi tting ends left open for future connection shall be bulkheaded by approved methods prior to backfilling. Unless otherwise specified or approved, all openings of 24 inches in diameter or less shall b~ closed off wi th prefabricated plugs or caps and all openings larger than 24 inches in diameter shall be closed off with masonry bulkheads. - 64 - - 65 - I I I I I I I I I I I I I I I I I I I Prefabricated plugs and caps shall be of the same material as the pipe material, or an 'approved, al ternate material, and they shall be installed with watertight seal as required for the pipeline joints. Masonry bulkheads shall be constructed with clay or concrete brick to a wall thickness of eigqt inches. Bulkheads installed for temporary service during con- struction may be constructed wi th two-inch timber planking securely fastened together and adequately braced, as an alternate to the masonry construction. C5 Placement of Insulation Rigid insulation board shall be placed within the pipe encasement zone, 6 inches above the pipe. Prior to placement of the insula.tion, encasement material shall be compacted until there is no further visual evidence of increased consolidation or the density of thecornpacted layer conforms to the density requirements specified in the Special Provisions, then leveled and lightly scarified to a depth of t inch. Encasement zone material placed below the insulation shall be free of rock or stone fragments measuring It inches or greater. Insulation boards shall be placed on the scarified material with the long dimension parallel to the centerline of the pipe. Boards placed in a single layer shall be overlapped at least 6 inches on all sides to eliminate continuous joints for the full depth of the insulation. If two or more layers of insulation boards are used, each layer shall be placed to cover, the joints of the layer immediately below with an overlap of at least 6 inches. The Contractor shall exercise precaution to insure that all joints between boards are tight during placement and backfilling with only extruded ends placed end to end or edge to edge. The first layer of material placed over the insulation shall be 6 inches in depth, free of rock or stone fragments measuring It inches or greater. The material shall be placed in such a manner that construction equipment does not operate directly on the insulation and shall be compacted with equipment which exerts a contact pressure of less than 80 psi. The first layer shall be compacted until there is no further visual evidence of increasedconSolida- tion or the density of the compacted layer conforms to the density requirements specified in the Special Provisions. I I I I I I I I I I I I I I I I I I I D Appurtenance Installations Appurtenance items such as aprons, trash guards, gates and castings shall be installed where and as required by the Plans and in accordance wi th such standard detail drawings or supplementary requirements as may be specified. Casting assemblies installed on manhole or catch basin structures shall be set in a full mortar bed and be adjusted to the specified elevation without the use of shims or blocking. Sewer aprons shall be subject to all applicable requirements for installation of pipe. All aprons and outfall end sections shall have the last three sections tied. Two tie bolt fasteners shall be placed in each of the last three joints, one on each side of top center at the 60 degree point (from vertical). Tie bolt diameter shall be: t inch for 12" to and including 21" pipe; 5/8 inch for 24" to and including 36" pipe; 3/4 inch for 42" to and including 54 n pipe; and 1" for 60" and larger pipe. The tie bolts shall be of a design approved by the Engineer. E Sewer Service Installations Main sewer service connections and building service sewer pipe shall be installed as provided for in the Contract and as may be directed by the Engineer. The sewer service connections and pipe lines shall be installed in conformance with all applicable requirements of the main sewer installation and as more specifically provided for herein. The Engineer, wi th the assistance of the Contractor, shall keep accurate records of all service installations as to type, location, elevation, point of connection and termination, etc. This service record shall be maintained jointly by the Contractor and Engineer on forms provided by the Engineer. The service installations shall not be backfilled until all required information has been obtained and recorded. The main sewer service connection shall consist of installing a Branch Tee or Wye section in the main sewer line at designated locations, or of providing an insert type Saddle Tee in a pipe cutout where and as permitted or required in lieu of the built-in fitting. Orienta.tion of service connection fitting shall be as shown in the standard drawings unless otherwise directed by the Engineer. - 66 - -67- I I I I I I I I I I I I I I I I I I I Where the depth of cover over the main sewer invert is greater than 15 feet (or such other maximum as may be indicated), the service connection shall be extended upward by means of a Service Riser Section in accordance with the details shown in the standard drawings. Unless otherwise specified, service pipe shall be installed at right angles to the main sewer and at a straight line grade to the property line. The standard and minimum grades shall be a uniform rise of one inch in four feet for sanitary service lines and one inch in eight feet for storm sewer service lines. These minimum grades may be reduced (by not more than one-half pitch) where the Engineer so approves in the case of restrictive elevation differences. Building service pipe lines shall generally be kept as deep as required to serve the building elevation and maintain the specified minimum pipe grades. Pipe bends shall be provided as necessary to bring the service lines to proper location and grade. Pipe bends shall not exceed 22tdegrees without approval of the Engineer. Unless otherwise indicated, service pipe installation shall terminate at property line or as designated on the Plans, with a gasketed plug placed in the end, at which point the Contractor shall furnish and set a 4 x 4 inch wooden timber 6 feet to 8 feet in length embedded 4 feet below grade, or approved steel post to mark the exact end of pipe. The timber or post shall beset vertically, with the top 2 feet painted green. Wherever service line connections to the main sewer are permitted or required to be made'by the open cut-out method in the absence of a built-in Tee or Wye fitting, the connection shall be made by using an approved type of Saddle Tee fitting. The pipe cut-out shall be made with an approved type coring machine or by other approved methods producing a uniform, smooth circular cut-out as required for proper fi t. The cut-out discs shall be retrieved and shall not be allowed to remain within the main sewer pipe. The Saddle Tee shall be securely fastened to the main sewer pipe by means of epoxy resin or other approved adhesive. The entire connection fitting shall be encased in concrete to a minimum thickness of six inches and as may be shown in the standard drawings. Wherever service line connections to the main sewer are required to be made by means of built-in Branch Tee or Wye fi ttings , the Contractor shall, in the absence of such fitting, remove a section of the main sewer pipe and replace i t wi th the required Branch Tee or Wye section connected by means of an approved sleeve coupling. I I I I I I I I I I I I I I I I I I I Sanitary sewer service lines shall not be connected to a manhole at an elevation more than 24 inches above the crown of the outgoing sewer. Where the elevation difference is greater than 24 inches, the connection shall be made by means of an Outside Drop Connection in accordance with the details shown in~the standard drawings. All pipe and .fitting openings at temporary terminal points .shall be fi tted wi th sui table plugs or shall be bulkheaded as required for the main sewer pipe. F Manhole and Catch Basin structures Manholes, catch basins, and other special access structures shall be constructed at designated locations as required by the Plans and in accordance with any standard detail drawings or special design requirements given therefor. Unles's otherwise specified or approved, manholes and catch basins shall be constructed on a cast-in-place concrete base and the barrel riser sections, cone section and top adjusting rings shall all be of precast concrete. All uni ts shall be properly fi tted and sealed to form a completely watertight structure. Barrel and cone height shall be such as to permit placement of at least three and not more than six standard two-inch precast concrete adjusting rings immediately below the casting assembly which shall be set in a mortar bed. Each adjusting ring shall also be set in mortar. Unless otherwise specified or approved, manholes and catch basins shall have an inside barrel diameter at the bottom of 48 inches minimum and the inside diameter at the top of the cone section and of all adjusting rings shall be of the same size and shape as the casting frame. Casting assemblies shall be as specified in the Plans. Catch basin grate elevation shall be adjusted as necessary to maintain the required dip below normal gutter grade. The concrete cast-in-place base shall be poured on undisturbed or firmly compacted foundation material which shall be trimmed to proper elevation. The bottom riser section shall be set in fresh concrete or mortar and all other riser section joints of the tongue and groove design shall be sealed with rubber gaskets. Wherever special designs so require or permit, and as otherwise may be approved by the Engineer, a precast concrete base may be used or the structure may be constructed wi th solid sewer brick or block uni ts or wi th cast-in-place concrete. Any combination of cast-in-place - 68 - - 69 - I I I I I I I I I I I I I I I I I I I concrete allowed complete sections. and brick or block mortar construction will be and may be required where it is impossible to the construction wi th standard precast manhole All annular ~wall space surrounding the inplace storm sewer pipes shall be completely filled with mortar or concrete, and the inside bottom of each manhole and catch basin shall be shaped with fresh concrete to form free flow through invert troughs as directed. Sanitary sewer main lines shall not be connected to a manhole at an elevation more than 24 inches above the invert of the outgoing sewer. Where the difference is greater than 24 inches, the connections shall be made by means of an Outside Drop Connection in accordance with the detailed drawings in the Plans. The concrete base under the drop connection shall be monolithic with thernanholebase. G Reconnecting Existing Facilities Disposition of abandoned facilities and reconnection of existing facilities shall be as provided for in the Plans, SpecifiGations, and Special Provisions. H Sanitary Sewer Leakage Testing All sanitary sewer lines, including service connections, shall be substantially watertight and shall be tested for excessive leakage upon completion and before connections are made to the service by others. Each test section of the sewer shall be subjected to exfiltration testing, either by hydrostatic or air test method as described below and at the Contractor's option. The requirements set forth for maximum leakage shall be met as a condition for acceptance of the sewer section represented by the test. If the ground water level is greater than three feet above the invert elevation of the upper manhole and the Engineer so approves, infiltration testingrnay be allowed in lieu of the exfiltration testing, in which case the allowable leakage shall be the same as would be allowed for the Hydrostatic Test. All testing shall be performed by the Contractor without any direct compensation being made therefor, and the Contractor shall furnish all necessary equipment and materials, including plugs and standpipes as required. HI Air Test Method The sewer pipe section under test shall be clean at the I I I I I I I I I I I I I I I I I I I time of testing but the pipe may be wetted. Pneumatic balls shall be used to plug the pipe ends at manholes. Low pressure air shall be introduced into the plugged line until the internal air pressure reaches 4.0 psi greater than the average back pressure of any ground water pressure that may submerge the pipe. At least two minutes shall be allowed for the air temperature to stabilize before readings are taken and the timing started. During this time the Contractor shall check all plugs with soap solution to detect plug leakage. If plugs are found to leak, air shall be bled off, the plugs shall be retightened, and the air shall be reintroduced into the line. The sewer section under test will be accepted as having passed the air leakage test if it does not lose air at a rate to cause the pressure to drop from 3.6 to 3.0 psi in less time than one-half minute per inch in diameter of the pipe tested. H2 Hydrostatic Test Method After bulkheading the test section, the pipe shall be subjected to a hydrostatic pressure produced b.ya head of water at a depth of three feet above the invert elevation of the sewer at the manhole of the test section. In areas where ground water exists, this head of water shall be three feet above the existing water table. The water head shall be maintained for a period of one hour during which time it will be presumed that full absorption of the pipe b.ody has taken place, and thereafter for an extended period of one hour the water head shall be maintained as the test period. During the one hour test period, the measured water loss wi thin the test section, including service stubs, shall not exceed the Maximum Allowable Loss (in Gallons Per Hour per 100 Feet of Pipe) given below for the applicable Main Sewer Diameter. Main Sewer Diameter (In Inches) 6 8 IO 12 IS 18 21 24 & Larger Maximum Allowable Loss* (In Gallons Per Hour Per 100 Feet) 0.5 0.6 0.8 1.0 1.2 1.4 1.7 1.9 *Based on 100 Gallons Per Day Per Pipe Diameter Inch Per Mile - 70 - If measurements indicate exfiltration within a section is not greater than the allowable maximum, section will be accepted as passing the test. test the I I I I I I I I I I I I I I I I I I I H3 Test Failure and Remedy In the event. of test failure on any test section, testing shall be continued until all leakage has been detected and corrected to meet the requirements. All repair work shall be subject to approval of the Engineer. Introduction of sealant substances by means of the test water will not be permitted. Unsatisfactory repairs or test results may result in an order to remove and replace pipe as the Engineer considers necessary for test conformance. All repair and replacement work shall be at the Contractor's expense. I Pipeline Backfilling Operations All pipeline excavations shall be backfilled to restore pre-existing condi tions as the minimum requirement, and fulfill all supplementary requirements indicated in the Plans and Specifications, and Special Provisions. The backfilling operations shall be started as soon as conditions will permit on each section of pipeline, so as to provide continuity in subsequent operations and restore normal public service as soon as practicable on a section-by-section basis. All operations shall be pursued diligently, wi th proper and adequate equipment, as will assure acceptable results. The backfilling shall be accomplished wi th the use of Suitable Materials selected from the excavated materials to the extent available and practical. Should the materials available within the trench section be unsuitable or insufficient, without loading and hauling or the employment of unreasonable measures, the required additional materials shall be furnished from outside sources as an Extra Work item in the absence of any Special Provisions requirements. Suitable Material shall be defined as a mineral soil free of foreign materials (rubbish, debris, etc.), frozen clumps, oversize stone, rock, concrete or bituminous chunks, and other unsuitable materials, that may damage the pipe installation, prevent thorough compaction, or increase the risks of after settlement unnecessarily. Material selection shall be such as to make the best and fullest utilization of what is available, taking into consideration particular needs of different backfill zones. Material containing stone, rock, or chunks of any sort shall only be utilized where and to the extent there will be no detrimental effects. - 71 - I I I I I I I I I I I I I I I I I I I Wi thin the pipe bedding and encasement zones described as that portion of the trench which is below an elevation one foot above the top of the pipe, the materials placed shall be limited in particle size to It inches maximum in the case of pipe of 12 inches in diameter or less, and to 2 inches maximum ~.in the case of larger pipe. Above these zones, the placement of material containing stones, boulders, chunks, etc. greater than 8 inches in any dimension shall not be allowed. Compaction of materials placed within the pipe bedding and encasement zones shall be accomplished with portable or hand equipment methods, so as to achieve thorough consoli- dation under and around the pipe and avoid damage to the pipe. Above the cover zone material, the use of heavy roller type compaction equipment shall be limited to safe pipe loading. Backfill materials shall be carefully placed in uniform loose thickness layers of 8 inches spread over the full width and length of the trench section to provide simultaneous support on both sides of the pipeline. Granular backfill may be placed in l2-inch layers above an elevation one foot above the top of the pipe, and with the provision that, by authority and at the discretion of the Engineer in consideration of the demonstrated capability of special type vibrating compactors, the stated maximums may be increased. Each layer of backfill material shall be compacted effectively, by approved mechanical or hand methods, until there is no further visual evidence of increased consoli- dation or the density of the compacted layer conforms to the density requirements specified in the Special Provi- sions. Compaction of the inplace layer shall be completed acceptably before placing material for a succeeding layer thereon. The manner of placement, compaction equipment and procedure effectiveness shall 'be subject to approval of the Engineer. All surplus waste materials remaining after completion' of the backfilling operations shall be disposed of in an acceptable manner within 24 hours after completing the backfill work on each particular pipeline section. Disposal at any location wi thin the proj ect limi ts shall be as specified, or as approved by the Engineer; otherwise, disposal shall be accomplished outside the project limits at the Contractor's discretion. The backfilling and surplus or waste disposal operations shall be a part of the work required under the pipeline installation items, not as work that may be delayed until final cleanup. - 72 - - 73 - I I I I I I I I I I I I I I I I I I I Until expiration of the guarantee period, the Contractor shall assume full responsibility and expense for all backfill settlement and shall refill and restore the work as directed to maintain an acceptable surface condi tion, regardless of location. All additional materials required shall be furnis~ed without additional cost to the Owner. J Restoration of Surface Improvements Wherever any surface improvements such as pavement, curbing, pedestrian walks, fencing, or turfing have been removed, damaged or otherwise disturbed'by the Contractor's operations, they will be repaired- or replaced to the Engineer's satisfaction, as will restore the improvement in kind and structure to the preexisting condition. Each item of restoration work shall be done as soon as practicable after completion of installation and backfilling operations on each section of pipeline. In the absence of specific payment provisions, as separate Contract Items, the restoration work shall be compensated for as part of the work required under those Contr:act Items which necessitated the destruction and replacement or repair, and there will be no separate payment therefor. If separate pay items are provided for restoration work, only that portion of the repair or reconstruction which was necessitated by the Contract work will be measured for payment. Any irnprovementsrernoved or damaged unnecessarily or undermined shall be replaced or repaired at the Contractor's expense. Jl Turf Restoration Turf restoration shall be accomplished by sod placement except where seeding is specifically allowed or required. Topsoil shall be placed to a minimum depth of four inches under all sodding and in all areas seeded. The topsoil material used shall be light friable loam contain- ing a liberal amount of humus, and shall be free of heavy clay, course sand, stones, plants, roots, sticks and other foreign matter. Topsoil meeting these requirements shall be selected from the excavated materials to the extent available and needed. All turf establishment work shall be done in sub.stantial compliance with the provisions of MnDOT Specification 2575. Seed shall be Mixture No. 5 of MnDOT Specification 3876, unless otherwise directed or approved. I I I I I I I I I I I I I I I I I I I J2 Pavement Restoration The inplace pavement structure (including base aggre- gates) shall be restored in kind and depth as previously existed, using base aggregates salvaged from the excavated materials to the extent available and needed, and with new materials beingbrovided for reconstruction of the concrete or bituminous surface courses. If , through no faul t of the Contractor in fail ing to reserve sufficient aggregate materials from the excava- tions, there should be insufficient quanti ty of sui table aggregate to reconstruct the pavement base courses, the- additional materials required will be furnished by the Owner at its expense, or the Contractor will be ordered to furnish the additional materials from outside sources as an Extra Work item in the absence of an appropriate Contract item therefor. Placement of any additional aggregate materials delivered to the si te by the Owner or of any additional materials furnished by the Contractor, shall be an incidental expense, as will also be the disposal of any excess materials resulting therefrom, unless special payment provisions are otherwise agreed upon. Reconstruction of aggregate base courses and concrete or bituminous surface courses shall be in substantial compli- ance with all applicable MnDOT Specifications pertaining to the item being. restored. The materials used shall be comparable to those used in the inplace structure, and the workmanship and finished quality shall be equal to that of new construction to the fullest extent obtainable in consideration of operational re~trictions. Existing concrete and bituminous surfaces at the trench wall shall be sawed or cut with a cutting wheel toforrn a neat edge in a straight line before surfaces are to be restored. Sawing or cutting may be accomplished as a part of the removal or prior to restoration at the option of the Contractor. However, all surface edges will be inspected prior to restoration. J3 Restoration of Miscellaneous Items Wherever any curbing, curb and gutter sections, pedes- trian walks, fencing, driveway surfacing, or other improve- ments are removed or in any way damaged, or undermined, they shall be restored to original condition by repair or replacement as the Engineer considers necessary. Replace- ment of old materials will be acceptable only to the extent that existing quality can be fully achieved, such as in the case of fencing. Otherwise new materials shall be provided - 74 - - 75 - I I I I I I I I I I I I I I I I I I I and placed as the Engineer directs. Workmanship and finished quality shall be equal to that of new construc- tion, where new materials are used, to the extent obtainable in consideration of operational restrictions. A proper foundation shall be prepared before reconstruc- ting concrete or bituminous improvements. Unless otherwise directed, granular material shall be placed to a depth of at least four inches under all concrete and bi tuminous i terns. No direct compensation will be made for furnishing and placing this material even though such course was not part of the original construction. K Maintenance and Final Cleanup All subgrade surfaces shall be maintained acceptably until the start of surfacing construction or restoration work, and until the work has been finally accepted. Additional materials shall be provided and placed as needed to compensate for trench settlement and to serve as temporary construction pending completion of the final surface improvements. Final disposal of debris, waste materials, and other remains or consequences. of construction, shall be accom- plished intermittently as new construction items are completed and shall not be left to await final completion of all work. Cleanup operations shall be considered as being a part of the work covered under the Contract items involved and only that work which cannot be accomplished at any early time shall be considered as final cleanup work not attributable to a specific Contract Item. If disposal operations and other cleanup work are not conducted properly as the construction progresses, the Engineer may withhold partial payments until such work is satisfactorily pursued, or he may deduct the estimated cost of its performance from the partial estimate value. Maintenance of sodded and seeded areas shall include adequate watering for plant growth and the replacement of any dead or damaged sod as may be required for acceptance of the work. L Deflection Test Deflection tests shall be performed on all plastic gravity sewer pipes. The test shall be conducted after the sewer trench has been backfi lIed to the desired finished grade and has been in place for 30 days. I I I I I I I I I I I I I I I I I I I The deflection test shall be performed by pulling a rigid baIlor pointed mandrel through the pipe without the aid of mechanical pulling devices. The baIlor mandrel shall have a minimum diameter equal to 95% of the actual inside diameter of the pipe. The maximum allowable deflection shall not exceed fi ve percent of the pipe's internal diarnet~r. The time of the test, method of testing, and the equipment to be used for the test shall be subject to the approval of the Engineer. All testing shall be performed by the Contractor at his expense wi thout any direct compensation being made there- for, and he shall furnish all necessary equipment and materials required. Ll Test Failure and Remedy In the event of test failure on any test section, the section shall be replaced, with all repair work subject to approval of the Engineer. The replaced section shall be retested for leakage and deflection in conformance with the specifications contained herein. All repairs, replacement, and retesting shall be at the Contractor's expense. M Televising Sewer line televising may be required by the Engineer, at the cost of the Contractor, if visual inspection, leakage testing, or deflection testing, indicate the sewer has not been constructed in accordance with these specifi- cations and the requirements of the Plans, Specifications and Special Provisions. 2621.4 METHOD OF MEASUREMENT All items will be measured separately according to design designation as indicated in the Pay Item name and as may be detailed and defined in the Plans, Specifications, or Special Provisions. Pipe will generally be designated by size (inside diameter or span), strength class, kind or type, and laying condition. Complete-in-place i terns shall include all component parts thereof as described or required to complete the unit, but excluding any excesses covered by separate Pay Items. Linear measurement of piping will include the running length of any special fittings (tees, wyes, elbows, gates, etc.) installed within the line of measure between specified terminal points. A Sewer Pipe Sewer pipe of each design designation will be measured - 76 - - 77 - I I I I I I I I I I I I I I I I I I I by length in linear feet along the line of pipe. Terminal points of measurement will be the pipe end at free outlets; the point of connection with inplace pipe; the center of manholes or catch basins; the point of centerline intersec- tions at branch fi ttings; or the point of juncture wi th other appurtenances or units as defined. Separation of quantities according to "depth zone classification";' when so designated in the Pay Item, will be determined by depth of pipe invert below the ground surface profile. B Manholes Manholes of each design designation will be measured by number of each constructed complete-in-place, including the base and castings as required, but excluding any excess depth greater than 8.0 feet measured from top of manhole cover to invert elevation of lowest pipe.

C Catch Basins Catch basins of each design designation will be measured by number of each constructed cornplete-in-place, incl~ding the base and castings as required, but excluding any excess depth greater than 5.0 feet measured from top of grate (low point) to invert elevation of lowest outlet pipe. Excess catch basin depth of .each design designation will be measured by the linear foot difference in depth between the 5.0 feet allowed as standard and the actual increased depth as constructed. D Outside Drop Connection Outside drop connections of each design will be measured by number of each constructed cornplete-in-place,including granular encasement, fittings, and any special piping details as required, including two holes into existing manholes for the drop connection, but excluding any excess vertical drop greater than 2.0 feet measured between invert of high pipe inlet and invert of low pipe outlet. Excess drop connection depth will be measured by the linear foot difference in vertical drop between the 2.0 feet allowed as standard and the actual increased vertical drop as constructed. I I I I I I I I I I I I I I I I I I I E Service Connection Service Connections of each design will be measured by number of each constructed complete-in-place as specified. F Service Pipe Service pipe of each design will be measured separately by length in linear feet, horizontally along the line of installation, between the service end and the point of juncture with the main pipe connection fitting. G Special Pipe Fittings Special pipe fittings (wyes, tees, bends, etc.) of each design designation will be measured by number of each installedcomplete-in-place as specified, but excluding any such fittings required to be installed as a component part of any other Work Unit. H Appurtenant Items Appurtenant i terns such as aprons, trash guards, gates and other prefabricated units or assemblies as identified by Pay Item name will be measured separately by number of each installed complete-in-place as specified. I Granular Materials Granular materials furnished and placed as special foundation, bedding, encaserne~t, or backfill construction will be measured by weight or volume of material furnished by the Contractor from outside sources and placed wi thin the limits defined. Unless otherwise specified, volume will be determined by vehicular measure (loosevolurne) at the point of delivery. Measurements will not include any materials required to be placed as a component part of any other Work Unit. J Piling Piling shall be measured according to the Provisions of MnDOT Specification 2452. Jl Pile Bents Pile bents shall be measured as a unit and shall include all materials and labor .required, except the pile. - 78 - - 79 - I I I I I I I I I I I I I I I I I I I K Insulation Rigid board insulation shall be measured on a square foot basis installed to the specified thickness noted on the Plans, Specifications, and Special Provisions and shall include all materials and labor required for placement. 2621.5 BASIS OF PAYMENT Payment for sewer. pipe and service pipe items at the Contract prices per linear foot of pipe of each design shall be compensation in full for all costs of providing a complete-in- place pipeline, including_ excavation, foundation preparation, backfilling, leakage testing, restoration of surface improve- ments, disposal of surplus or waste materials, final cleanup, and such other work as may be specified, but excluding the construction of other structures or special sections and the placement of special fittings, appurtenances or materials specifically designated for payment under other Contract Items. Payment for manhole, catch basin, outside drop connection, service connection, and other structures as specified, at the Contract prices per structure, shall be compensation in full for all costs of constructing each unit complete-in-place as specified, including all required castings, special fittings ,. base or encasement, and appurtenant materials as specified for the complete structure or section, but excluding such additional work as may be designated for payment under other Contract Items. VJhere.the specifiedstandardrnanhole, catch basin, or outside drop connection depths are exceeded, the excess depth of each design will be paid for separately .as linear footage i terns and payment at the Contract prices therefor shall be compensation in full for all costs of providing the extra depth. Special pipe fi ttings such as wyes, tees and bends will be paid for as separate Contract Items to the extent they are required to be installed in the sewer pipe and service pipe lines and not as a component part of a complete-in-place structure (outside drop connections,service connections, etc.) Appurtenant i terns such as aprons, trash guards, drainage gates, and other prefabricated units or assemblies and specials as designated will be paid for as separate Contract Items to the extent they are not included as a component part of any complete-in-place structure.

Within the construction limits, as required, the removal of improvements such as paving, curbing, walks, turf, etc., shall be subject to acceptable replacement after completion of underground work, with all expense of removal and replacement being borne by othe Contractor unless separate compensation is specifically provided for in the Contract. Obstructions such as street signs, mailboxes, guard posts, culverts, and other items of prefabricated construction may be temporarily removed during construction provided essential service is maintained in a relocated setting as approved by the Engineer and nonessential items are properly stored for the duration of construction. Upon completion of the underground work, all such items shall be replaced in their proper setting by and at the sole expense of the Contractor. In the event of damage to any surface improvements, either privately or publicly owned, the Contractor will be required to replace or repair the damaged property to the satisfaction of the Engineer and by the Contractor at his expense. E. Interference of Underground Structures When any underground structure interferes with the planned placement of pipe or appurtenances and requires alterations in the work to eliminate the conflict or avoid endangering effects on either the existing or proposed facilities, the Contractor shall immediately notify the Engineer and the Owner of the affected structures. When any existing facilities are endangered by the Contractor's operations, he shall cease his operations at the site and take such precautions as may be necessary to o protect the inplace structures until a decision is made as to how the conflict will be resolved. Without specific authorization from the utility owner, no essential utility service shall be disrupted, nor shall any change be made in either the existing structures or the planned installations to overcome the interference. Alterations to existing facilities will be allowed only when that service will not be curtailed unavoidably and then only when the encroachment or relocation will satisfy all applicable regulations and conditions. 3 - 12 745000m /6 F. SPEC-745.000 Wherever alterations are required as a result of unforeseen underground interference's not due to any fault or negligence of the Contractor, the Engineer will issue a written change order covering any additional or extra work involved and specifying the revised basis of payment, if any. Any alterations made strictly for the convenience of the Contractor shall be subject to prior approval and shall be at the Contractor's expense. No extra compensation will be allowed for delays caused by the interference of underground structures unless approved by the Engineer and included in a change order. Removal"" of Surface Improvements Removal of surface improvements in connection with trench excavation shall be limited to actual needs for installation of the pipeline and appurtenances. Removal operations shall be coordinated effectively with the excavation and install~tion operations as will cause the least practical disruption of traffic or inconvenience to the public. Removed debris shall not be deposited at locations that will restrict access to fire hydrants, 'private driveways, or other essential servic~ areas. Removal and final disposal of debris shall be accomplished as a single operation wherever possible and the debris shall be removed from the site before starting the excavating operations. Remov"al of concrete or bituminous structures shall be by methods producing clean-cut breakage that will preserve the remaining structure without damage. Concrete or bituminous paving shall be removed so when the trench is excavated there will be a six inch wide minimum undisturbed subgrade and aggregate base course lip. Removal equipment shall not be operated in a manner that will cause damage to the remaining or adjoining property. Where not removed to an existing joint, concrete structures shall be sawed along the break lines to a minimum depth of one-third of the structure depth. .

G. Excavation and Trench Preparation Excavating operations shall proceed only so far in advance of pipe laying as will satisfy the needs for construction of work and permit advance verification of unobstructed line and grade as planned. Where interference with existing structures is possible or in any \vay indicated, and \vhere necessary to establish 3 - 13 745000m I I I I I I I I I I I I I I I I I I I It, I I I I I I I I I I I I I I I I I I I SPEC-745.000 elevation or direction for connections to inplace structures, the excavating shall be done at those locations in advance of the main operation so actual conditions will be exposed in sufficient time to make adjustments without resorting to extra work or unnecessary delay. All installations shall be accomplished by open trench construction except where boring and jacking or tunnel construction methods shall be employed as specifically required by the Plans or approved by the Engineer. Surface structures must be properly supported and the backfill restored to the satisfaction of the Engineer. The excavation operations shall be conducted to carefully expose all inplace underground structures without damage. Wherever the excavation extends under "or approaches close to an existing structure as to endanger it in any way, precautions and protective measures shall be taken as necessary to preserve the structure and provide temporary support. Hand methods of excavating shall be utilized to probe for and expose such critical or hazardous installations as gas pipe and power or telephone cables. G.1 Classification and""Disposition of Materials: All materials encountered in the excavations, with the exception of items classified for payment as structure removals, will be considered as Unclassified Excavation. Unclassified materials shall include muck, rubble, wood debris, boulder stone, masonry or concrete fragments less than one (1) cubic yard in volume, together with other miscellaneous matter that can be removed effectively with power operated excavators. Excavated materials will be classified for reuse as being either Suitable or Unsuitable for backfill or other specified use, subject to selective controls. All suitable materials shall be reserved for backfill to the extent needed, and any surplus remaining shall be utilized for other construction on the project as may be specified or ordered by" the Engineer. To the extent practical, granular materials and topsoil shall be segregated from other materials during the excavating and stockpiling operations so as to permit best use of the available materials at the time of backfilling. All excavated materials reserved for backfill or other use on the project shall be stored at locations approved by the Engineer that will cause a minimum of nuisance or inconvenience to public travel, adjacent properties, and other special interests. The material shall not be deposited so close to the edges of the excavations as would create hazardous conditions, nor shall any material be placed so as to block the access to emergency services. All materials considered unsuitable by the Engineer, for any use on the project, shall be immediately removed from the project and be disposed of as arranged for by the Contractor. 3 - 14 745000m 1/ SPEC-745.000 G.2 G.3 Excavation Limitations and Requirements: Trench excavating shall be to a depth that will permit preparation of the foundation, as specified, and installation of the pipeline and appurtenances at the prescribed line and grade except where alterations are specifically authorized. Trench widths shall be sufficient to permit the pipe to be laid and joined properly and the backfill to be placed and compacted as specified. Extra width shall be provided as necessary to permit convenient placement of sheeting and shoring and to accommodate placement of appurtenances. Excavations shall be extended below the bottom of structure grade as necessary to accommodate any required Granular Bedding material. When unstable foundation materials are encountered at the established grade, additional materials shall be removed as specified or ordered ~ by the Engineer to produce an acceptable foundation. All excavations below grade shall be to a minimum width equal to the outside pipe diameter plus two (2) feet. Where no other grade controls are indicated or established for the pipeline, the excavating and foundation preparations shall provide a minimum cover over the top of the pipe of 7.5 feet to the proposed final grade as indicated on the plans. Trench widths shall allow for at least six inches of clearance on each side of the joint hubs. The maximum allowable width of the trench at the top of pipe level shall be the outside diameter of the pipe plus two (2) feet, subject to the considerations for alternate pipe loading set forth below. The width of the trench at the ground surface shall be held to a minimum to prevent unnecessary destruction of the surface structures while maintaining safe working conditions. The maximum allowable trench width at the level of the top of pipe may be exceeded only by approval of the Engineer, after coonsideration of pipe strength and loading relationships. Any alternate proposals made by the Contractor shall be in writing, giving the pertinent soil weight data and proposed pipe strength alternate, and shall be madoe in a timely manner so as not to delay the project. Approval of alternate pipe designs shall be with the understanding that there will be no extra compensation will be allowed for any increase in material or construction costs. Sheeting and Bracing Excavations: All excavations shall be sheeted, shored, and braced as will meet all requirements of the applicable safety codes and regulations; comply with any specific requirements of the Contract; and prevent disturbance or settlement of adjacent surfaces, foundations, structures, utilities, and other properties.

Where conditions warrant extreme care, the Contractor shall exercise special precautions to protect life or property. This may include the installation of sheet piling of the interlocking type or shall include other safety measures be taken as the Contractor deems necessary. The Contractor shall at all times be responsible for protection of life, property, and the work on the project. The Contractor shall assume full responsibility for proper and adequate placement of sheeting, shoring, and bracing, wherever and to such depths that soil stability may dictate the need for support to prevent displacement. Bracing shall be so arranged as to provide ample wo~king space and so as not to place stress or strain on the inplace structures to any extent that may cause damage. Sheeting, shoring and bracing materials shall be removed only when and in such manner as will assure adequate protection of the inplace structures and prevent displacement of supported grounds. Sheeting and bracing shall be left in place only as required by the Contract. Otherwise, sheeting and bracing may be removed as the backfilling reaches the level of respective support. Wherever sheeting and bracing is left in place, the upper portions shall be cut and removed to an elevation of three (3) feet or more below the established surface grade or as the Engineer may direct. All costs of furnishing, . placing and removing sheeting, shoring and bracing materials, including the value of materials left in place as required by the Contract, shall be included in the prices bid for pipe installation and will not be compensated for separately. When any sheeting, shoring, or bracing materials are left in place by written order of the Engineer, payment may be made for those materials as an extra work item, including waste material resulting from upper cut-off requirements. Preparation and Maintenance of Foundations: Foundation preparations shall be conducted to produce a stable foundation and provide continuous and uniform pipe bearing between bell holes. Where -Class C bedding is specified, the initial excavating or backfilling operations shall produce a subgrade level slightly above finished grade to permit hand shaping to finished grade by trimming of high spots and without the need for filling of low spots to grade. 3 - 16 745000m 11 In excavations made below grade to remove unstable materials, the backfilling to grade shall be made with Granular Foundation material. Placement of the backfill shall be in relatively uniform layers not exceeding eight (8) inches in loose thickness. Each layer of backfill shall be compacted thoroughly, by means of approved mechanical compaction equipment, to produce uniform pipe support throughout the full pipe length and facilitate proper shaping of the pipe bed. Where the foundation soil is found to consist of materials that the Engineer considers to be so unstable as to preclude removal and replacement to a reasonable depth to achieve solid support, a suitable foundation shall be constructed as the Engineer directs in the absence of special requirements therefore in the Contract. The Contractor shall be required to furnish and drive piling and construct concrete or timber bearing supports or other work as provided for in an extra work order. Care shall be taken during final subgrade shaping to prevent any over-excavation. ~hould any low spots develop, they shall only be filled with Granular Foundation material, which shall be compacted thoroughly, without additional compensation provided to the Contractor. The finished subgrade shall be maintained free of water and shall not be disturbed during pipe lowering operations except as necessary to remove pipe slings. The discharge of trench dewatering pumps shall be directed to natural drainage channels or storm water drains in a manner which does not cause damage to private or public property. Any debris left by dewatering operations shall be cleaned up immediately by the Contractor. Draining trench water into sanitary sewers or combined sewers will not be permitted. The Contractor shall install and operate a dewatering system of wells or points to maintain pipe trenches free of water wherever necessary or as directed by the Engineer to meet the intent of these specifications. Unless otherwise specified in the Plans, Specifications, or Specific Requirements, such work shall be considered incidental with no additional compensation provided therefore. All costs of excavating below grade and placing. foundation or bedding aggregates as required shall be included in the bid prices for pipe items to the extent that the need for such work is indicated in the Contract provisions and the BID does not provide for payment therefore under separate BID items. If examination by the Engineer reveals the need for placement of foundation aggregates was caused by the Contractor's manipulation of the soils in the presence of excessive moisture or lack of proper dewatering, the cost of the corrective measures shall be borne by the Contractor.

Where concrete reaction blocking is placed, the water main shall not be subjected to- hydrostatic pressure until at least 5 days have elapsed after the concrete placement, with the exception that this period may be reduced to 2 days where high early strength concrete is used. At the option of the Engineer, the pressure and leakage tests may be conducted simultaneously. Any defective joints, pipe, fittings, valves, or hydrants, revealed during the testing or before fmal acceptance of the work shall be satisfactorily corrected and the tests shall be repeated until the specified requirements have been met. B.l Pressure Test: The section being tested shall be slowly filled with water and the specified test pressure shall be applied after all air has been expelled from the pipe. A hydrostatic pressure of 150 pounds per square inch, gauge pressure, measured at the lowest point of elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. . I The gauge pressure shall be checked after a minimum of two (2) hours. A pressure drop of 1 psi or less will be cause to accept the test section. Several attempts must be made to satisfy the Engineer the pressure test will not be successful. If the drop is more than 2 psi after these attempts, the Engineer may authorize the leakage test in writing for acceptance. Service Pipe may be te~ted at the time of the foregoing test, if installed, at the Contractor's option. However, testing of service pipes may be completed as a separate operation from main testing, and if so, the test pressure shall be 100 p.s.i. Service pipe testing, if done separately, shall be done with the corporation stop open. 3 - 35 745COOm I I I I I I I I I I I I I I I I I I 8~ I, I I I I I I I I I I I I I I I I I I SPEC-745.000 B.2 Leakage Test: After an unsatisfactory pressure test, and if authorized in writing by the Engineer a leakage test shall be performed on each valved section of water main to determine the quantity of water that must be supplied into the section to maintain a test pressure of 150 pounds per square inch, after the air in the pipeline has been expelled and the pipe has been filled with water. The water added shall be recorded to the nearest fluid ounce. After filling the pipe with water and expelling all air in the line, a pressure of 150 psi shall be applied in the same manner as prescribed for the pressure test, and sufficient water shall be measured and supplied into the pipe section to maintain the pressure for a test duration of two (2) hours. Each pipe section tested will be accepted if the leakage does not exceed the quantity determined by the formula as shown in the table below, based on an allowable leakage of 11. 65 gpd/mile/nominal diameter inch at 150 psi.

Proceed with seeding in late May to mid June witK the selected native seed mixture and appropriate cover crop. If the area to be seeded is small or irregular in shape, broadcasting seed with hand broadcasting equipment is adequate. Equipment must be capable of broadcasting chaffy and light seed without plugging or settling in the holding chamber. If the area to be seeded is large and regular in shape, seeding should be completed with a specially designed native seed drill. . 4. If the seed is broadcast, the area should be harrowed and packed again. This will provide the best soil to seed contact and maximize the certainty of seedling establishment. 5. Clean native grass mulch should be applied in moderate thickness. Mulch is adequately applied when approximately 50% of the soil is visible after application. 6. The seeding site should be mowed at least one time during the seeding year and 2 times in the first year after seeding. Mowing should be completed when weeds are no more than three feet ta II. Mowing height should be approximately six inches. If the mowed mulch is heavy it should be removed to prevent "smothering" the new seedlings. 7. Spot treatment with a he~bicide to eliminate undesirable weeds may be required. 3 Seed Mixture for Wet Areas A seed mixture should be selected from local seed sources. This will be best suited for the environmental conditions of the seeding area. Our suggestion for a seed mixture of appropriate grass and wildflower seeds for a marginally wet area would include the following species in the approximate percentages listed: Grass mixture Big bluestem Canada Wild Rye Little Bluestem GiantManna Grass Dark Green Bulrush Canada Bluejoint Wooly Bulrush Fox Sedge 250/0 30 5 7 2 2 4 1 Indian Grass Prairie Cordgrass Prairie Dropseed Softstem Bulrush River Bulrush .Bottlebrush Sedge Giant Burreed 10 5 1 2 2 2 2 it The grass mixture should be seeded at approximately 10 pounds (Pure Live Seed basis) per acre.
