CONTRACTOR shall not be required to resume Work in connection with such condition 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 pazagraph 10.05. 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.

Whenever an item of material or equipment is specified or described in the Contract Documents by using the name of a proprietary item or the name of a particulaz Supplier, the specification or description is intended to establish the type, function, appeazance, 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. Suppliers may be submitted to ENGINEER for review under the circum- stances described below. L "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.OS.A.1, 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 vi the Contract Documents. 2. Substitute Items a. If in ENGINEER'S sole discretion an ip~m of material or equipment proposed by CONTRACTOR does not qualify as an "or-equal" item tinder 00700 - 19 pazagraph 6.OS.A.1, 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.OS.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 application 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 similaz 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, xechnique, sequence, or procedure of construction is shown or indicated in and expressly "~ 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 subpazagraph 6.OS.A.2. C. Engineer's Evaluation: ENGINEER will be allowed. a reasonable time within which to evaluate each proposal or submittal made pursuant to paragraphs 6.OS.A and 6.OS.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. 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. ' E. ENGWEER'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.OS.A.2 and 6.OS.B and in making changes in the Contract Documents (or in the provisions 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. F. C'ONTRACTOR'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 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. B. If the Supplementary Conditions require the identity of certain Subcontractors, Suppliers, or other individuals or 0000 - 20 0 u i~ U ~~ ~! ~~ L 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 arty 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. 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.

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. 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° £ONTRACTOR's legitimate obligations associated with prior Applications for Payment. 3. The amount of retainage with respect to pro- gress payments will. be as stipulated in the Agreement. B. Review of Applications 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. 2. ENGINEER's recommendation of any payment requested in an 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~ 0 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 pazagraph 9.08, and to any other qualifications stated in the recommendation); and 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 final 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 cleaz of any Liens. 5. ENGINEER may refuse to recommend 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 pazagraph 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, ~7 revise or revoke any such payment recommendation OWNER. shall .promptly .pay CONTRACTOR the , previously made, to such extent as may be necessary in ENGINEER'S opinion to protect OWNER fro l amount so withheld, or any adjustment thereto agreed to m oss because: by OWNER and CONTRACTOR, when CONTRAC- TOR corrects to OWNER'S satisfaction the reasons for a. the Work is defective; or completed Work such action.

I I r~ I 0 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. 14.05 Partial 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. 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 far 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. If ENGINEER considers that part of the Work to be substantially complete, the provisions of paragraph 14.04 will apply with respect to certification of Substantial Completion of that part of the Work. and the division of responsibility in respect thereof and access thereto... 00700 - 39 1. After CONTRACTOR has, in the opinion of ENGINEER, satisfactorily completed all corrections identified during the final inspection and has delivered, in accordance with the Contract Documents, all main- tenance and operating instructions, schedules, guazan- tees, Bonds, certificates. or other evidence of insurance certificates of inspection,. marked-up record documents (as provided in paragraph 6.12), and other documents., CONTRACTOR may make application for final payment following the procedure for progress payments. 2. The final Application for Payment shall be accompanied (except as previously delivered) by: (i) all documentation called for in the Contract Documents, including but not limited to the evidence of insurance required by subparagraph 5.04.B.7; (ii) consent. of the surety, if any,. to final. payment;-and (iii) complete and legally effective releases or waivers (satisfactory to OWNER) of all Lien rights azising out of or Liens filed in connection with the Work. 3. In lieu of the releases or waivers of Liens specified in pazagraph 14.07.A.2 and as approved by OWNER, CONTRACTOR may furnish receipts or releases in full and an affidavit of CONTRACTOR that: (i) the releases and receipts include all labor, services, material, and equipment for which a Lien could be filed; and (ii) all payrolls, material and equipment bills, and other indebtedness connected with the Work for which OWNER or OWNER'S property might in any way be responsible have been paid or otherwise satisfied. If any Subcontractor or Supplier fails to furnish such a release or receipt in full, CONTRACTOR may furnish a Bond or other collateral satisfactory to OWNER to indemnify OWNER against any Lien. 2. No occupancy or separate operation of part of the Work may occur prior to compliance with the requirements of paragraph 5.10 regarding property insurance. 14.06 Finallnspection A. Upon written notice from CONTRACTOR that the entire Work or an agreed portion. thereof is complete, ENGINEER will promptly make a final inspection with OWNER and CONTRACTOR and will notify CON- TRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. CONTRACTOR shall immediately take such measures as aze necessary to complete 'such Work or remedy ..such deficiencies. 14.07 Final Payment A. Application for Payment- B. Review of Application and Acceptance 1. If, on the basis of ENGINEER'S observation of the Work during construction and final inspection, and ENGINEER'S review of the final Application for Payment and accompanying documentation as required by the Contract Documents, ENGINEER is satisfied that the Work has been completed and CONTRACTOR's other obligations under the Contract Documents have been fulfilled, ENGINEER will, within ten days after receipt of the final Application for Payment, indicate in writing ENGINEER'S recommendation of payment and present the Application for Payment to OWNER for pay- ment. At the same time ENGINEER will also give written notice to OWNER and CONTRACTOR that the Work is acceptable subject to the provisions of pazagraph 14.09. Otherwise, ENGINEER will return the Application for Payment to CONTRACTOR, indicating in writing the reasons for refusing to recommend final payment, in which case CON- TRACTOR shall make the necessary corrections and resubmit the Application for Payment. C. Payment Becomes Due 1. 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, final completion of the Work is significantly delayed, and. if ENGINEER so confirms, OWNER shall,. upon receipt of CONTRACTOR'S final 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 .pazagraph 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 final payment, except that it shall not constitute a waiver of Claims. 14.09. Waiver of Claims 1. a waiver of all Claims by OWNER against CONTRACTOR, except Claims azising from unsettled Liens, from defective Work appeazing after final inspection pursuant to pazagraph 14.06, from failure to comply with the Contract Documents or the terms of any special guazantees specified therein, or .from CONTRACTOR'S continuing obligations under the Contract Documents; and 2. a waiver of all Claims by CONTRACTOR against OWNER other than those previously made in writing which are still unsettled. ARTICLE 15 -SUSPENSION OF WORK AND TERMINATION 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 will be 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 pazagraph 10.05. 15.02 OWNER May Terminate for Cause A. The occurrence of any :one 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 pazagraph 2.07 as adjusted.. from time to xime pursuant to pazagraph 6.04); 2. CONTRACTOR's disregard of Laws or Regulations of any public body having jurisdiction; 3. CONTRACTOR'S disregazd of the authority of ENGINEER; or 4. CONTRACTOR'S violation in any substantial way of any provisions of the Contract Documents. A. The making and acceptance of final payment will B. If one or more of the events identified in paragraph constitute: i5.02.A occur, OWNER may, after giving CONTRACTOR (and the surety, if any) seven days written notice, terminate 00700 - 40 0 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 fuush 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 azbitration 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 ~ o~,a~~. ~,a~e~m ~em~~,~.a price for the Work performed. C. Where CONTRACTOR'S services have been so germinated 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. 15.03 OWNER May Terminate For Convenience i~ 0 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;. 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 uncompleted Work, plus fair and reasonable sums for overhead and profit on such expenses; 3. for all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, azchitects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) incurred in settlement of terminated contracts with Subcontractors, Suppliers, and others; 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. 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 finally 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 finally 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 pazagraph 15.04 are not intended to preclude CONTRACTOR from making a Claim under pazagraph 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 ARTICLE 17 -MISCELLANEOUS 17.01 Giving Notice A.

Proper drainage shall beprovided at all times so that the subgrade will be kept free of standing water. Any soft spots , developing from poor drainage and standing water shall be completely excavated, backfilled, and compacted with an acceptable dry material at no additional cost to the Owner. 2.03 EXCAVATI_O_ N AND EMBANKMENT (2105) All operations shall be done in accordance with MnDOT Specification No. 2105. All compaction will be done by , D u i~ r i~ u the "Specked Density Method". Density tests shall be taken to evaluate the compaction achieved. The quantity of tests shall be determined by the Engineer in the field. Where density tests aze taken to evaluate the compaction, the fill shall meet the requirements of a minimum of 100% of Standard Proctor Density (AASHTO T-99) in the upper three feet of the embankment and a minimum of 95% of Standard Proctor Density below the upper three feet. At the time of compaction, the moisture content of the backfill material shall be not less than 75%, nor more than 125%, of "optimum", the Engineer may, at his discretion, revise the compaction requirements. The Engineer reserves the right. to reject materials which aze over "optimum" moisture content. ' ~ Subgrade excavation is further defined under Section 2.06 of these specifications. Granulaz borrow and select granular borrow shall meet the requirements of MnDOT Specification No. 3149; maximum particle size to be six inches in diameter. 2.04 TEST ROLLING (2111 MODIFIED) After the above work relative to compaction is completed, the subgrade shall be test-rolled in accordance with MnDOT Specification No. 2111, except as follows: A. Test rolling shall be performed-prior to, intermittently during, and after completion of subgrade preparation (2112) or subgrade excavation work (2105) when ordered by the Engineer. The limits of yielding or rutting portion of this Specification 2111.3 shall apply only to the test roll for final acceptance of the subgrade preparation; earlier test rolling shall be for the purpose of identifying .those areas needing subgrade 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'k".measured from the top of the constructed grade to the bottom of the rut. The "required density" shall be 100% Standard Proctor. In embankment/fill areas,. the subgrade may be test rolled at an elevation lower than finished subgrade elevation if the condition of the soils being placed indicatethat normal subgrade preparation (2112) cannot be performed and that subgrade 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 subgrade 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. B. The Contractor will furnish a wheel loader (with operator) or other equipment approved by the Engineer for test rolling. The wheel loader shall have an approximate bucket size of three cubic yards and shall be fully loaded. Test rolling will be required over the entire length and width of the proposed roadway and one foot outside the back of curb. Test rolling shall be performed as many times as deemed necessary by the Engineer. The costs of the wheel loader and operator and any other costs incurred during test rolling shall be incidental to construction of the subgrade or base and no direct compensation will be made therefore. Test rolling, including re-testing of repaired,. failed sections, shall also be considered as incidental. 2.05 SUBGRADE PREPARATION (2112) The subgrade shall be prepared in accordance with MnDOT Specification 2112, except as follows: The Contractor shall have the option, at his discretion, to choose one of the methods described below for 2 0 subgrade preparation.

' subgrade previously determined satisfactory and now failing due to inclement weather also shall be repaired at no additional compensation. Tests shall be taken at the rate of one test for every 100 feet of subgrade prepared. Testing shall be by an ' independent test lab at the Contractor's. expense. Under no circumstances shall subbase material be hauled until the subgrade has been approved by the Engineer with respect to grade and density. 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 subgrade 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 3 ~ u ' prior to attempting subgrade preparation, subgrade soil removal (top 12"), and test rolling. 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: ' A. Common Excavation Material (2105.2A) 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 zhe 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 commom.borrow material; as .described:below. The excavation and replacement areboth paid through the-: ' unitbid price of the material used for replacement. ~~ 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 subgrade 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. ' 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 subgrade excavation. 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. T.he excavation:-and replacement:~are :both paid through-the unit bid.price of the material used for replacement. ' All materials used for replacement in areas of subgrade excavation shall be compacted in accordance with 2105, as previously mentioned in Section 2.03. Payment for subgrade 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. INCLEMENT WEATHER: Na 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 subgrade preparation by use of 2112, 2105, and/or Section 2.05, the Engineer may require ' the Contractor to prepare the roadways asfollows: - A. Make a core excavation of the subgrade to a depth as directed by the Engineer. ' 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 subgrade 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 subgrade excavation has been made and 0 u the conditions do not allow for compaction, then the bottom of the subgrade 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 ' subgrade before any rolling or compaction begins. All compaction done in this situation shall be by use of static equipment. C. When this procedure for subgrade excavation is used, the Contractor shall be paid for excavating the , unsuitable materials below subgrade elevation and shall be paid for all base materials used above and below subgrade 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 subgrade preparation ' (2112).

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 replaced at 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 in 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 radius of 100 feet or less. Division plates shall be metal. u The fron ' t 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. ' FINISHING ' 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 1/a of the cross section of the concrete. Contraction joints may be sawed, hand-formed, or .made by U8 inch-thick division plates in the 1 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 1/8-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 extruded 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. L! i~ i~ i~ Other Joints Construction joints maybe 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 in 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 detai14.017A. 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 35° 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. ' Backfilline 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. Testm~ -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 abullet- , 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 minimurn laboratory preparation and the best test results. Test 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. All testing shall be done at the Contractor's expense bean approved testing laboratory Test results shall be ' subrrutted once a week to the Engineer.

F2 Granular Material Use Designations Granular materials provided for Foundation, :Bedding, Encasement, or Backfill use as required by the Plans:, Specifications and Special Provisions,. either as part of the pipe item work unit or as a separate Contracts Item, shall be classified as to use in accordance with the following: - 50 - Material Use Designation Zone :Designation ' Granular Foundation -------- placed below the bottom of pipe grade as replacement for unsuit- able or unstable soils, to achieve ' better foundation support. Granular Beddin -'~------____ g 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,. cif 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 limit f s_ o each zone are established to define variable needs for material gradation d ' .an compaction or void content, taking into consideration the sequence o£ con- struction and other conditions. The material use and zon e 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 Piling Piling shall. be constructed in accordance with- rovi- ' . signs of MnDOT Specification 2452. ~ H Insulation Main insulation shall be extruded rigid board material havin a th l g erma conductivity of 0.23 BTU/hour/square foot/de ree F h h g a ren eit/per inch thickness, maximum, at 40°F mean, a compressive strength of 35 psi minimum, a-nd water absorption f 0 o .25 percent by volume maximum.

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 permitted 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 o:r 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, th~~ fire department, municipal bus service, school bus service, and ambulance service. The Contractor shall keep the rE:quired agencies informed 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 Waterman or service -and the bottom of the sanitaryr 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 t-etween the bottom of the sewer and the top of the water~main; 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 - Watermains shall be laid at least l0 feet horizontally from any sanitary 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 tYxe 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 shall 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 assistancemaybe 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 without. approval of the Engineer. _ 53 _ , ' 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 the Contractor to the extent that .separate compensation is not specifically prov~.ded 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 setaing as approved by the Engineer and that nonessential items are ' properly stored for the duration of construction. Upon completion of the underground work, all such items ~~hall be replaced in their proper setting at the sole expense of the ' Contractor. In the event of damage to any surface improvements, either privately or publicly owned, in the absence of. construction necessity the Contra tor ill b , c w e regL~ired to replace or repair the damaged property to the sati~cfaction 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 ' eliminate the conflict or avoid endangering effE~cts 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 ho th fli i w e con ct w ll be ..resolved. Without specific authorization from the Engineaer, 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- b ons in existing facilities will be allowed only to the - extent that service will not be curtailed unavoidably and then only kThsn 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 an~,r 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 - 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. A5 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 with the work. Removal operations shall be coordinated effectively 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 deposited 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. u u u 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, such. . as aggregate, sod, or topsoil shall b e segregated from oth er waste materials and be stockpiled so as to maintain suitabilit and it y perm 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 ofdrop weight breaking operations at any time. _ „_ ~ C~ d A6 Temporary Service Measures While any open excavations are maintained, the (,ontrac- for shall have available a supply. of steel plates >uitable for temporary bridging of open trench sections where either vehicular or pedestrian traffic must be maintained. Use of the plates shal'1 be as directed or approved by the Engineer and where installed they shall be secured against ~~ossible displacement and be replaced with the permanent st`,ructure 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 exX>osed 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 wil l be allowed only where the surface structure can be properly supported and the ~~ackfill .restored to the satisfaction of the Engineer... II i~ 0 The excavating operations shall be conducted s<~ as to carefully expose all inplace underground structures without damage. Wherever the excavation extends under or ap~~roaches so 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 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 - 0 life 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 materials 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 items 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. practicable, 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 - 57 - 0 fl !I ~I it 0 0 D 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 that will cause a minimum of inconvenience to public travel, V•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 materi l n i . a s co s dered unsuitable by the Engineer, for any use on the project, shall be immediately removed from the project and- be ' disposed of as arranged by the Contractor at no extr~~ cost to the Contract. ' B3 Excavation Limitations and Requirements Trench excavating .shall be to a depth that wi 11 ~~ermit ' preparation of the foundation as specified and instal`Lation 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 ro e l and th b f p p r y e ack ill 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 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 remo d . ve as specifiE~d or ordered by the Engineer to produce an acceptable fc>unda- tion. Unless otherwise indicated or directed rock shell be ' , removed to an elevation at least six inches beloiN-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 hori~,ontal dimensions as will provide a minimum clearance o:° six L inches on all sides of appurtenant structures su~~h as valves housin s access t t , g , s ruc ures, etc. Where. no other grade controls are indicated or esta- blished for the pipeline, the excavating and founcation 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 joint hubs. The maximum allowable .width of the trench ' - 58 - 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 allowable 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. ~i 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 with 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. The .Contractor shall assume. full responsibility for proper and adequate placement of sheeting, shoring, and - 59 - ~i n i~ i~ u II II ~I~ ~, I!, 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 working space and so as not to place stress or strain can the nplace structures to any extent that may cause damage.. j 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 shell be left in place:. only as required by the Plans, Specifica- tion 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 and bracing is left in place, the upper portions ..shall be cut and removed. to wn elevation of three feet or more below the established surface grade as the Engineer may direct. A11 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, in the absence of specific requirements. of the Contract to do so, payment will b~~ made for those materials as an 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 ~~ermit 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 0.03 foot of a straight line between pipe joints and to provide bell-hole excavation at each joint as will ~>ermit proper joining of pipe and fittings. In excavations made below grade to remove rock or unstable materials, the backfilling to grade shall bey 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 Extr~i 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 absence 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 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. 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.. ' - 61 - C Installation of Pipe and Fittings C1 Inspection and Handling Proper and adequate implements, tools,. and .facilities satisfactory to the Engineer shall be provided and Lied by the Contractor for 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.

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.. While suspended and before .being lowered into laying position each pipe section and t ,. appur enant unit shill 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. prescrit~e 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 dete t d ll c e she be corrected by cleaning, trimming, or repair as needed. ' C2 Pi L i pe. ay ng Operations Trench excavation and bedding preparations shall p:^oceed ahead of pipe placement as will permit proper laying and joining of the units at the prescribed grade and ali~~nment without unnecessary deviation or hindrance. ' All for i tt e gn ma er or dirt shall be .removed from the inside of the pipe and fittings before they are lowered into position in the trench and .they shall be kept clean by approved means during and after Pa i Th y ng. e sewer materials shall be carefully lowered into laying. position by the use of suitable restraining devices. Under no circumsi,ances ' shall the pipe be dropped into the trench. ' - 62 - At the time of pipe placement, the bedding conditions shall b e such as to provide uniform and continuous support for th i e p pe between bell holes.. Bell .holes shall be . excavated as necessary to make .the joint connections,-but they hall b l ' e no arger than would be adequate to support the pipe throughout its length No i m . p pe aterial shall be laid in water nor when the trench or bedding conditions e ' ar 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 permitted 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 b ll e . and the-pipe forced home and brought to correct line a d n grade. The pipe shall be secured in place with approved backfill material which shall b ' , e thoroughly, compacted by tamping around the pipe to a height of at least 12 inches above the top with hand operated mechanical tamping devices b or y hand. The joint areas .shall remain exposed and precautions. shall be taken t o prevent the soil from entering the joint space, until the joint seal i s effected. Backfill in the bell. area shall be left loose. ' Connection of pipe. to existin lines g or previously constructed manholes or catch basins shall be accomplished as shown in the Plans or as otherwise approved by the .Engineer Where 1 . necessary to make satisfactory closure or produce the required curvature rade li m , g or a gn ent deflec- tions at joints shall not exceed that which will :a sure s tight joints and comply with any limitations recommended by - th i -~ e p pe manufacturer.

Where the elevation difference is greater than 24 inches the connection h ll b , s a e m~ide by means of an Outside Drop Connection in accordance with the details. shown in~the standard drawings. ' l A l pipe and fitting openings at .temporary te:^minal • points .shall be fitted with suitable plugs or shall be ' bulkheaded as required for the main sewer pipe. ' F Manhole and Catch Basin Structures M h l h t an o es, ca c basins, and other special ~~ccess structures shall be constructed at designated locati~~ns as ' required by the Plans and in accordance with any standard .detail drawings or special design requirements given therefor. ' Unless otherwise specified or approved, manholes and catch basins shall be constructed on a cast-in•-place concrete base and the barrel riser sections, cone sE~ction ' and top adjusting rings shall all be of precast cone=rete. All units shall be properly fitted 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 as:~embly which shall be set in a mortar bed. Each adjustir~c 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 pit the top of the cone section and of all adjusting rings shill be of the same size and- shape as the casting frame.

All annular ;wall space surrounding the inplace storm e sew r 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 the manhole base. G Reconnecting Existing Facilities ' Disposition of abandoned facilities and reconnection of existing. facilities shall be as provided for in the Plans , Specifications, 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 testing .may be al owed ' 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. H1 Air Test Method The sewer. pipe section under test shall be clean at the , - 69 - ' 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 by a 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 existingwater 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 body 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 within 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 Maximum Allowable Loss* (In Inches) (In Gallons Per Hour Per 100 Feet) 6 0.5 8 _.. 0.6 10 _ 0.8 12 1.0 15 1.2 18 1.4 - 21 1.7 24 & Larger 1.9 *Based on 100 Gallons. Per Day Per Pipe Diameter Inch Per Mile - 70 - If measurements indicate exfiltration within a test , section is not greater than the allowable maximum,. the section will be accepted. as passing the test. 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 replac e m e nt _ _ _ _ _ __ _ __ work shall be at the Contractor's expense. - _ _---- I Pipeline Backfilling.Operations All pipeline excavations shall be backfilled to restore ' pre-existing conditions 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, with proper and adequate equipment, as will ' assure acceptable results.. The backfilling shall. be accomplished: with 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 emplvyment ' ,_ _ of unreasonable measixres, 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~ u _~ i n 0 0 within 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 12 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 S 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 12-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 within the project. limits 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. f! ' - 72 - D 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 condition,. regardless of location. All additional materials required. shall be furnished 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 Contract 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 improvements removed or damaged unnecessarily or undermined shall be replaced or repaired at the Contractor's expense. J1 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 .substantial compliance with the provisions of MnDOT Specification 2575. Seed shall be Mixture No. 5 of MnDOT Specification 3876, unless. otherwise directed or approved. fl - 73 - D i D II 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 being provided for reconstruction-of.the concrete or bituminous surface courses. If, th-rough no fault of the Contractor in failing to reserve sufficient aggregate materials from the excava- tions, there. should be insufficient quantity of suitable 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 site 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. restrictions.: Existing concrete and bituminous surfaces at the trench. wall shall be sawed or cut with a cutting wheel to form- a neat edge in a straight line before surfaces are to be restored. Sawing or cutting may be accomplished as apart. 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 7 li 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 - 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- Ling concrete or bituminous improvements. Unless otherwise ' directed, granular material shall be placed to a depth of at least four inches under all .concrete and bituminous items. No direct compensation will be made for furni hing ' and placing this material even though such course was not part of the original. construction. g 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. Fi l , na 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 nat 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 Defl ti t s ' ec on e ts shall be performed on all plastic gravity sewer pipes. .The test shall be conducted after the sewer trench has been backfilled to the desired finished grade and has been in place for 30 days. ' - 75 - ' - ' The deflection : test shall be performed by pulling a rigid ball or pointed mandrel through the pipe without the aid of mechanical pulling devices. The ball or mandrel shall have a minimum diameter equal to 95% of the. actual inside diameter of the pipe. The maximum allowable deflection .shall not exceed five percent of the pipe's ' internal diameter. and the equipment The time of the test, method to be used for the test shall of testing, be subject to the approval of the Engineer. ' All testing shall be performed by the Contractor at his expense without any direct compensation being made there- for, and he shall furnish all. necessary equipment. and materials. required. ' L1 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 MEASUREN~NT ii 1 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. items shall .include all. component parts thereof as described or required to complete the unit, but excluding any excesses covered by separate Pay Items.

Till the area to be seeded to prepare a seedbed and control early spring weeds. 2. Harrow and .pack the area to be seeded. This will create an adequate seedbed for final seeding. Packing will be considered adequate when only a slight footprint is left in the soil after walking across the area. 3. .Proceed with seeding in late May to mid June with 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. 1f 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 tall 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 herbicide to eliminate undesirable weeds may be required. 3 1 J ' 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 25% Indian Grass 10 Canada Wild Rye 30 Prairie Cordgrass 5 Little Bluestem 5 Prairie Dropseed 1 ' Giant Manna Grass 7 Softstem Bulrush 2 Dark Green Bulrush 2 River Bulrush 2 Canada Bluejoint 2 Bottlebrush Sedge 2 ' Wooly Bulrush 4 Giant Burreed 2 Fox Sedge 1 R The grass mixture should be seeded at approximately 10 pounds {Pure Live Seed basis) per acre. ' Wildflower mixture Culvers root 0.5% Tall Meadow Rue 9.5 ' Purple Prairie Clover 5.0 White Prairie Clover 7.0 Bottle Gentian 0.5 Marsh Blazing Star 0.5 St. Johns Wort 1.0 Maximillion Sunflower 5.0 Boneset 3.0 Golden Alexander 7.0 , Pale Gentian 0.5 Prairie Blazing Star 5.0 Blackeyed Susan 4.0 False Sunflower 12.0 Blue Vervain 4.0 Marsh Milkweed 3.0 , Wild Bergamont 4.0 False Indigo 3.0 Ftattopped Aster 3.0 Cupplant 2.0 New England Aster 3.0 Blue Flag Iris. 7.0 ' Red Stemmed Aster 1.0 Mud Plantain 2.0 Marsh Betony 0.5 Joepye Weed 3.0 ronweed 4.0 , The wildflower mixture should be seeded at approximately 3 pounds (PLS) per acre. We recommend that ashort-lived cover crop of Regreen (10 pounds per acre) be seeded with this mixture , to help crowd out weeds and minimize risk of soil erosion.
