I 9.4 - ENGINEERS STATUS I The Engineer shall be the Owner's representative during the construction period. All instructions of the Owner to the Contractor shall be issued through the Engineer. The duties and responsibilities and the limitations of authority of the Engineer as the ~ler's representative during construction are set forth in these General Conditions and shall not be extended without written consent of the Owner and the Engineer. I I The Engineer will make periodic visits to the site to observe the progress and quality of the executed work and to determine, in general, if the work is proceeding in accordance with the Contract Documents. He will not be required to make exhaustivl! or continuous on-site inspections to check the quality or quantity of the work. The Engineer will not be responsible for the construction means, methods, techniques, sequences or procedures, or the saftey precautions incident thereto. I I I GC-9 9.4 ENGINEERS STATUS - CONT. His efforts will be directed toward providing assurance for the Owner that the completed project will conform ~o the requirements of the Contract Documents, but he will not be responsible for the Contractor's failure to perform the work in accordance with the Contract Documents. Based on his on-site observaticn as an experienced and qualified professional, he will keep the Owner informed of the progress of the . work and will endeavor to guard che Owner against defects and deficiencies in the work of Contractors. The Engineer will have the authority to disapprove of or reject work which is defective and does not conform to the requirements of the Contract Documents or does not meet the requirements of any inspection, test or approval referred to in the Documents. He will also have authority to require special inspection or testing of the work whether or not the work is fabricated, installed or completed. If the Owner and the Engineer agree, the Engineer will provid~ one or more full time Resident Project Representati:ves to assist the Engineer in carry~ng out his responsibilities at the site. Neither the Engineer's authority to act under this Section nor any decision made by him in good faith either to exercise or not to exercise such authority shall give rise to any duty or responsibility of the Engineer to the Contractor, any Subcontractor, any of their agents or employees, or any other person performing any of the work. 'The Engineer'or his rep~ese~tative will not be responsible for the acts and omissions of the Contractor, or any Subcontractor, or any of his or their agents or employees, or any persons performing the work. 9.5 ENGINEERS INTERPRETATIONS & DECISIONS The Engineer will be the initial interpreter of the terms and conditions of the Contract Documents and the judge of the performance thereunder.

Claims, disputes and other matters relating to the execution and progress of the work or the interpretation of or performance under the Contract Documents shall be referred initially to the Engineer for decisions, which he shall render in writing within a reasonable time. All such decisions of the Engineer shall be final, except in cases where time and/or financial considerations are involved, which if no agreement in regard thereto is reached, shall be subject to arbitration. GC-IO I I I I I I I I I I I I I I I I I I I I I 9.6 RESIDENT PROJECT REPRESENTATIVE I The Resident Project Representative is a representative of the engineer. He is under the authority and supervision of the Engineer. It is his duty to observe the workmanship and materials of the Contractor for comptiance with the Contract Documentz. He has the same authority as the Engineer except that he may not make changes in either the plans or specifications. He has the authority to stop the work whenever such stoppage is necessary for proper execution of the Contract. He then witl immediately contact the Engineer to get a decision on proceeding. If the Contractor continues to work after being told by the Resident Project Representative to suspend work. he does so at his own risk. and any such work may be ordered redone at the Contractor's expense. I I I 9.7 OBSERVATION AND TESTING I If the Contract Documents. laws. ordinances. rules. regulations or orders of any public authority having jurisdiction require any work to specifically be inspected. tested. or approved by someone other than the Contractor. the Contractor will give the Engineer timely notice of readiness .therefore. The Contractor'will. furnish the Engineer the required certificates of inspecti~n. testing or approval. All SUC~l tests will be in accordance with the methods prescribed by the American Society for Testing and Materials or such other applicable organization as may be required by law or ~he Contract Documents. If any such work required so to be inspected, tested or approved is covered up without written approval or consent of the Engineer, it must, if directed by the Engineer, be uncovered for inspection at the Contractor's expense. The -, c..ost...of .all_ s.uc.b.. .in.sp.ec.t.io.n,s., ..tes.U .and.. ap.provals .shall be,.oorne by che Contractor unless otherwise provided. I I I I Any work which fails to meet the requirements of the Contract Documents shall be considered defective. Such defective work shall be corrected at the Contractor's expense. I I Neither observations by the Engineer nor inspection, tests or approvals by persons other than the Contractor shall relieve the Contractor from his obligations to perform the work in accordance with the requirements of the Contract Documents. I 9.8 NEGLECI'ED WORK I If the Contractor should neglect to prosecute the work in accordance with the Contract Documents, including any requirements of the progress schedule, the Owner, after three days written notice to the Contractor may, make good such deficiencies and the cost thereof (including compensation for additional professional services) shall be charged against the Contractor if the Engineer approves such action, in which case a Change Order shall be issued incorporating the necessary revisions in the Contract Documents including an appropriate reduction in the Contract Price. If the payments then or thereafter due the Contractor are not sufficient to Cover such amounc, the Contractor will pay the difference to the Owner. I I I I GC-ll SECTION 10 - WORK COMPLETION AND PAYMENTS 10.1 CHANGES IN THE WORK Without invalidating the Contract, the Owner, through the Engineer, may order changes in, additions to and deductions from the work. Any adjustments in Contract costs or time of completion caused by such changes shall be made at the time of ordering such change. The Engineer may, during the life of the Contract, issue additional instructions necessary to illustrate changes in the work. The Engineer shall hav~ the aur.hority to make minor changes in the work not involving extra cost and not inconsistent with the overall intent of the Contract Documen~s. These may be accomplished by a Field Order. If the Contractor believes that any minor change or alteration authorized by the Engineer entitles him to an increase in the Contract Price, he may ~~ke a claim therefore as provid~d in Section 10.2. Additional work performed by the Contractor without ~l,~horization of a Change Order will not entitle him to an increase in the Contract Price or an extension of the Contract Time, except in the case of an emergency as provided in Section 8. The- Owner will' execute' any appropriate Change'Order prepared by the Engineer covering changes in the work to be performed, work performed in an emergency, and any other claim of the Contractor for a change in the Contract Time or the Contract Price which is approved by the Engineer. It shall be thp.

All duties, responsibilities and obligations assigned to or undertaken by the Contractor shall be at his expense without change in the Contract Price. Should the number of units of completed work of any item included in the Unit Price schedule classified as a major item vary more than 204 from the number of units stated in said schedule, either the Owner or the Contractor may request a revision of the unit price for the item so affected. Under such conditions adjustment of ~he pri~e, if any, shall be made in accordance wit1 chis Section. A major item under the meaning of this provision is defined as any item equal to or greater than 104 of the total price for the entire contract. The Contract Price may only be changed by a Change Order. If the Contractor is p.ntitled by the Contrar.t Documents to make a claim for an increase in the Contract Price, his claim shall be in writing delivered to the Owner and the Engineer within 15 days of the occurence of the event giving rise to the claim. If the Owner and Contractor cannot agree on the amount, all claims for adjust- GC-12 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 10.3 I I I I I 10.2 CHANGE OF CONTRACT PRICE - CON~: ments in the Contract Unit Price shall be determined by the Engineer. Any change in the Cont~act Price resulting from any such claim shall be incorporated in a Change Order. The value of any work covered by any claim for an increase or de- crease in the Contract Price shall be determined in one of the following ways: A. By application of unit prices to the quantities of the items involved. B. By mutual acceptance of a lump sum. C. By cost and a mutually acceptable fixed amount for overhead and profit. If none of the above methods is agreed upon, the value shall be determined by the Engineer on the basis of costs and a percentage for overhead and profit. Costs shall only include labor (payroll, payroll taxes, fringe benefits, workman's compensation, etc.), materials, equipment, and other incidentals directly related to the work involved. The maximum percentage which shall be allowed for Contractor's combined overhead and prrfit,shall be as follows: Work done by his own organization, the Contractor may add up to ten percenr. of his actual net increase in cost, and for work done by Subcontractor may add up to ten percent.: of his actual net increase in costs for combined overhead and profit and the Contracto~ ~y,add "~p '"Coo' five -percent "of the -Subcom:...actor' s total for his combined" overhead and profit; provided that no overhead or profit shall be allowed on costs incurred in connection with premiums for public liability insurance or other special insurance directly related to such work. In such case and also under paragraph C. the Contractor will submit in form prescribed by the Engineer an itemized cost breakdown together with supporting data. CHANGE IN CONTRACT TIME The contract time may be changed only by a change order. If the Contractor is entitled to make a claim for an extension in the contract time based on the contract documents, his claim shall be delivered in writing to the Owner and the Engineer within ten days of the occurrence of the event giving rise to the claim. If the Owner and Contractor cannot agree the claims for adjustment in the contract time shall be determined by the Engineer. The contract time will be extended by the amount equal to time lost due to delays beyond the control of the Contractor if he makes a claim as provided above. GC-D 10.6 I I 10.4 PROGRESS PAYMENTS Unless otherwise provided, parcial payment documents will be prepared by the Engineer for completed work on the project. Payment documents will be prepared before the first of each month, and will be sub- mitted to the Owner for ...pprovaloefore the 10th of the month. The progress payments will he based on work completed and materials delivered tQ th~ job site on or b~fore the 20th of the preced1ng ~onth. I I I The Contractor warrants ~nd guarantees that the title to all work, materials and equipment covered by a Progress Payment Document, will have passed to the Owner prior to his signing of the Progress Payment Document, free and clear of all liens, claims, security interests and encumbrances (hereafter in these General Conditions referred to as "liens"). I I 10.5 The Owner will, within ten days of presentation to him of an approved Progress Payment Document, pay the Contractor 904 of the amount approved I by the Engineer. FINAL ACCEPTANCE OF WORK Thp. Ja~e of final acceptance of the work shall be the date of formal acceptance by the City or other local government. I if the work is not to be turned over to the City for ownership and maintenance, the date of final acceptance shall be the date of accep~ance by the Engineer as evidenced in writing to the Owner. Such eyidence 'may '..oe"'ei'tnera~ ie'tter'.of'.:rina'l 'acceptance; or in the absence of such a lett~r, a Final Payment Voucher indicating that the Engineer recommends that no funds be retained. I I FINAL PAYMENT I Upon notice from the Contractor that the project i~ complete, t~.e Engineer will make a final inspection with the Owner and the Contractor. Any items found to be defective during the inspection will be noted and the Engineer shall furnish in vriting to the Contractor a list of such items that are defective or unfinished. The Contractor shall immediately make such corrections as are necessary and to the satisfaction of the Engineer. The Contractor may request final payment when all corrective work is completed and all bonds, guarantees, certificates of inspection and other documents have been delivered, all as required by the Contract Documents. If the Engineer is satisfied that the work has been completed and the Contractor has fulfilled all of his obligations under the contract he will, within ten days after receipt of the Contractor's notice of completion and request for final payment, prepare the Final Payment Documents. I I I I In addition to the requirements of section 4.2 "Performance Bond," the Owner may require separate releases of all claims and waivers of all lien~ to be furnished by rhe Contractor before final payment is I I GC-14 I I I I 10.6 FIN~ PAYMENT - CONT.

If any claim or liens remains unsatisfied after all cayments are ~de, the Contractor shall be liable for all costs in satisfying these claims. I 10.7 PAYMENT WITHHELD PRIOR TO FINAL ACCEPTANCE OF WORK I The Owner may. because of subsequently discovered evidence, withhold or nullify the whole or part of any certificate of payment to such extent as may be necessary to protect himself from loss due to: I A. Defective work not remedied; I B. Claims filed or reasonable evidence indicating public filing of claims by other parties against the Contractor; I C. Failure of the Contractor to make payments properly to Subcontractnrs or for materials or labor; D. Damage to another Contractor; I When the above grounds a~e removed or the Contracto~ provides a Surety Bond satisfactory to the Owner in the amount Withheld, payment shall be made for amounts withheld. I 10.8 ERRORS IN PAYMENT I No certificate issued nor payments made nor occupancy of the work by the Owner shall be deemed as acceptance of any part of the work or materials not in accordance with the Contr~r.t. I Where an error is found after payment i~ m~ue, Lbe Owner shall have the right to recover or shall be reimbursed fo~o allover payments to the Contractor. , I 10.9 LIQUIDATED DAMAGES I The Contractor agrees that he can and will complete the work within the time limit stated in the Agreement. Inasmuch as the damages to the Owner from non-completion will be difficult to accurately assess, said damages will be liquidated at a daily rate of $150 for each calendar day beyond the contract completion date. The Owner will deduct and retain the amount of the liquidated damages from any monies due to the Contractor, and in case that those amounts are less than the liquidated damages, the Contractor shall be liable for the difference. Such retained amounts are not to be considered as a penalty but as payment for tangible and intangible damages to the Owner. I I I I r.r_1~ SECTION 11 I I 10.9 LIQUIDATED DAMAGES - CONT. I Permitting the Contractor to continue and finish the ~ork vr any part of it 3fter the time fixed for its completion may have been extended. will in no way be construed as ~ waiver on the part of the Owner of any of his rights under the Contract. I Neither by taking over the work by the Owner, nor by the annulment of the contract, shall the Owner forfeit the right to recover liquidated damages from the Contractor or his surety for failurp. to complete the contract. I I SUSPENSION OF WORK 11.1 SUSPENSION OF WORK BY THE 0~1ER I In the event it should beco~e necessary to stop work for an indefinite period, the Contractor shall store all materials in such a manner that they will not obstruc~ or impede traffic unecessarily nor be damaged in any w.. ~nd he shall take every precaution to protect from damage or detel:i..;,ration all of the work performed.

The concrete thrust blocking shall be cast-in-place concrete (concrete blocks or wood blocking is prohibited). Where restrained joints are required and the pipe is in a casing near the fitting to be restrained, the length of pipe in the casing shall not be included in the length of pipe necessary to develop sufficient soil friction to overcome thrust. Standard Detail Specifications Water Main Systems Albertville, MN 04/00 Page W-9 All hydrants, valves, services, stubs and extensions, blind flanges, plugs, and all things retaining water pressures must be tied with 'Megalug" joint restraints or accepted equal as a pressure restraint. 3. HYDROSTATIC TESTING After the pipe has been laid including fittings, services, valves and hydrants, and the line has been backfilled in accordance with these Specifications, all newly laid pipe, or any valved section thereof including building services unless otherwise directed by the Engineer, shall be subjected to a hydrostatic pressure test. Each valved section of pipe shall be slowly filled with water. The specified test pressure, measured at the highest point of elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. The pump, pipe connection, gauges, and all necessary apparatus shall be furnished by the Contractor. Before applying the specified test pressure, all air shall be expelled from the pipe. To accomplish this, taps shall be made if necessary at points of highest elevation and afterward tightly plugged. The test pressure shall be brought to 150 psi. Thereafter, the test shall be considered satisfactory if without additional water, the pressure remains constant for a period of 2 hours. A passing test will not lose more than 2 psi. 4. ELECTRICAL CONDUCTIVITY TEST After the hydrostatic test has been successfully completed, a conductivity test shall be conducted in accordance with the following specification: 4.1 Test Procedure The system (pipeline and hydrants) shall be tested for electrical continuity and current capacity. Backfilling shall have been completed. The line may be tested in sections of convenient length as accepted by the Engineer. Direct current of 350 amperes, :i: 10 percent, shall be passed through the pipe line for 5 minutes. Current flow through the pipe shall be measured continuously on a suitable ammeter and shall remain steady without interruption or excessive fluctuation throughout the5 minute test period. Insufficient current or intermittent current or arcing, indicated by large fluctuation of the ammeter needle, shall be evidence of defective electrical contact in the pipeline. The cause shall be isolated and corrected. Thereafter, the section in which the defective test occurred shall be retested as a unit and shall meet the requirements. 4.2 Notes on Test Procedure I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 04/00 Page W-10 Standard Detail Specifications Water Main Systems Albertville, MN Sources of D.C. current for these tests may be motor generators, batteries, arc welding machines, etc.; D.C. arc welding machines will probably be the usual source. These machines are available in adequate capacity for these tests and are equipped with controls for regulating the current output. Cables from the power source to the section of the system under test should be of sufficient size to carry the test current without overheating or excessive voltagedrop. Usable sizes will probably be in the range of 2/0 to 4/0 AW.G. Connections for the test shall be made at hydrants. The hydrants shall be in the open position with the caps on during the test. The cable shall be clamped to the top operating nut. Note: After the test, the hydrant shall be shut off and a cap loosened to allow hydrant drainage. Tighten cap after drainage. A hook-on type D.C. ammeter placed on one of the cables leading to the hydrant is a convenient method of measuring current. In using arc welding machines, the current control should be set at a minimum before starting. After starting the machine, advance the control until the current indicated on the ammeter is at the desired test value. Caution: In case of open circuits at joints or connections, the voltage across the defective joint or connection will be in the order of 50-100 volts. 5. DISINFECTION OF WATER MAINS 5.1 General All pipelines installed shall be disinfected with a strong chlorine solution. Disinfecting may be done concurrently with pressure and leakage testing or after pressure and leakage testing at the option of the Contractor. Each section line that is repaired shall be disinfected after such repairs are made. All necessary disinfection equipment and materials shall be provided by the Contractor. 5.2 Flushing The pipeline shall be flushed at a velocity of at least 2.5 feet per second immediately prior to disinfection. A 24-hour notice is required to the City Water Department for pipeline flushing. 5.3 Disinfectants Disinfection shall be performed using either chlorine gas or calcium hypochlorite solution. Chlorine gas shall conform to AWWA 8301 and shall be handled under pressure as an aqueous solution. Calcium hypochlorite shall conform to AWWA 8300 and shall be granules with 70 percent available chlorine. Standard Detail Specifications Water Main Systems Albertville, MN 04/00 Page W-11 5.4 Feeding Chlorine gas shall be used only as a solution. Introduction of chlorine gas into the pipeline directly will not be permitted. When chlorine is used, a chlorinator and booster pump with injector shall be provided. Calcium hypochlorite shall be made into a solution and pumped into the pipeline with a suitable chemical feed pump. 5.5 Application Pipelines shall be disinfected by either the continuous feed method or the slug method. In using the continuous feed method, chlorine feed shall be proportional to the rate of flow into the pipe so the entering water contains at least 50 mg/l of available chlorine. Chlorine application shall be continuous until the entire pipeline is filled with the chlorine solution. The treated water shall be retained in the pipeline for at least 24 hours and the chlorine residual at the end of the period shall be at least 25 mg/l. In using the slug method, chlorine shall be fed at a rate that will produce at least 300 mg/l in the water entering the pipeline and a sufficient quantity of water shall be chlorinated so all parts of the pipeline will be exposed to chlorine concentration of 300 mgll for at least 3 hours. During disinfection all valves and hydrants shall be operated to ensure all appurtenances are disinfected. 5.6 Bacteriological Tests The chlorine solution shall be flushed out of the line and samples shall be collected and tested for bacteriological quality after the line has set for a minimum of 24 hours. Thesamples shall be collected by the City Water Department personnel and the cost of these tests paid for by the Contractor. A 24-hour notice is required to the City Water Department for pipeline flushing. 5.7 Repeat Testing If initial disinfection fails to produce satisfactory bacteriological samples, the disinfection shall be repeated until satisfactory bacteriological samples are obtained. Costs for additional disinfection shall be borne by the Contractor. 5.8 Inspection The above operation shall be supervised by a qualified Inspector furnished by the Consultant. If a qualified Inspector cannot be supplied, the City shall furnish an Inspector. The City shall I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 04/00 Page W-12 Standard Detail Specifications Water Main Systems Albertville, MN have a least a 24-hour notice for said inspection. 6. WATER MAINS CROSSING SEWERS Water mains crossing sanitary sewers, storm sewers, or house sewers shall be laid to provide a separation of at least 18 inches between the bottom of the water main and the top of the sewer. When local conditions prevent a vertical separation as described, the following shall be used: 1. Sewers passing over or under water main shall be constructed of materials equal to water main standards of construction. 2. Water mains passing under sewers shall, in addition, be protected by providing: 1. A vertical separation of at least 18 inches between the bottom of the sewer and the top of the water main. 2. Adequate structural support for the sewers to prevent excessive deflection of joints and settling on and breaking the water mains. 3. The length of water pipe be centered at the point of crossing so joints will be equidistant and as far as possible from the sewer. Water mains shall be laid at least 10 feet horizontally from any sanitary sewer, storm sewer or sewer manhole whenever possible. When local conditions prevent a horizontal separation of 10 feet, a water main may be laid closer to a storm or sanitary sewer provided that: 1. The bottom of the main is a 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 water main standards of construction and shall be pressure tested to assure water tightness prior to backfilling. 7. MAINTAINING WATER SERVICE While construction is underway, the Contractor shall maintain water service to existing users on a continuous basis until service from the newly installed mains can be restored. The means and methods used are subject to the acceptance of the Engineer. Overland service lines connected to a hydrant via a common header is recommended. All service lines, headers, connections, and appurtenances shall be disinfected in accordance with Minnesota Health Department and AWWA rules and regulations.
