No plea of ignorance of conditions that exist or that may hereafter exist, or of difficulties that will be encount- ered in the execution of the work herew1der which result from the failure to make necessary examinations and investigations, will be accepted as a sufficient excuse for any failure or omission on the part of the Contractor to fulfill in every detail all the require- ments of this contract, or "lill be accepted as a basis for any claim whatsoever for extra compensation or for an extension of time. No bidder may rely upon any statements or representations of any officer, agent, or employee of the Owner with reference to the conditions of the work or the character of the soil or other hazards which may be encountered in the course of construction. 2. BID SECURITY Each bid shall be accompanied by a bid security in the form and amount as specified in the Advertisement for Bids. Such bid security is a guaranty that the bidder will enter into a contract with the O\~er for the work described in the proposal, and the amount of the bid security of a successful bidder shall be forfeited to the Owner as liquidated damages in the event that such bidder fails to enter into a contract and furnish Contractor's bond. 3. CONTRACT DOCU~~NTS The Contract Documents will consist of the Advertisement for Bids, Instructions to Bidders, General Conditions, Special Provisions, Special Conditions, Proposal Form, Form of Contract and all plans and dravlings. These documents are on file with the O\1ner. 4. Preparation of Proposal The bidder shall submi t his proposal .on the forms provided by the - 1 - IB Engineer without removing them from the bound Contract Documents. He shall also submit a duplicate proposal on the additional un- bound forms provided by the Engineer. The blank spaces in the proposals shall be filled in correctly with ink where indicated for each and every item for which a quantity is given, and the bidder shall state the prices for which he proposes to do each item of the work contemplated.

CONDITIONS IN BIDDER'S PROPOSAL The bidder shall not stipulate in his proposal any conditions not provided for on the proposal form. 6.

DELIVERY OF PROPOSALS All bids shall be placed in a sealed envelope with a statement thereon showing the work covered by the bid, and addressed to the address as stipulated in the Advertisement for Bids.

REJECTION OF PROPOSALS Proposals may be rejected if they show any omission, alteration of form, additions not called for, conditional bids or alternate bids not specified or irregularities of any kind. Proposals in which the prices are obviously unbalanced may be rejected. 9. WITHDRAWAL OF PROPOSALS A bidder may withdraw his proposal without prejudice to himself, provided he files a written request with the Owner before the hour of letting, and such withdrawn proposal may be modified and resubmitted by the bidder at any-time prior to the hour set for the opening of bids. ~- IB 10.

Bidders or their authorized agents are invited to be present. 11. DISQUALIFICATION OF BIDDERS More than one proposal for the same project from an individual firm, partnership or corporation under the same or different names will not be considered. Evidence that any bidder is interested in more than one proposal for the same work will cause rejection of all such proposals. Collusion between the bidders will be considered sufficient cause for the rejection of all bids so affected. Failure on the part of any bidder to carry out previous contracts satisfactorily or his lack of the experience or equipment neces- sary for the satisfactory completion of the work may be deemed sufficient cause for his disqualification. 12. EQUIPMENT wnen requested by the Owner, the bidder shall furnish a complete statement of the make, size, weight (where weight is one of the specified requirements) condition and previous length of service of all equipment to be used in the proposed work. 13.

FAILURE TO EXECUTE CONTRACTS Failure to furnish the contract bond in a sum equal to the amolli~t of the award, or to execute the contract within ten (10) days, as specified, shall be just cause for the annulment of the award, and it shall be understood by the bidder that in the event of the annulment of the award, the amount of the guaranty deposited with the proposal shall be retained by the Owner, not as a penalty, but as Liquidated Damages. - 3 - IB GENERAL CO~~ITIONS TABLE OF CONTENTS Article Page 1.

CHANGES IN THE HORK The O'i'.Jner, to the extent authorized by law, may order extra work or make changes by altering, adding to, or deducting from the work without invalidating the contract, and the contract sum will be adjusted accordingly. No such order for extra work or change shall be valid Q~less authorized by official action of the Owner, and communicated to the Contractor in writing. All such work shall be executed under the conditions of the original contract, except that any claim for extension of time caused thereby shall be adjusted at the time of ordering such change. The value of any authorized extra work or change shall be deter~mined for purpose of compensating the Contract in one or more of the follow- ing "Jays: 1) By unit prices named in the contract wherever such unit prices are applicable to the extra work or change. 2) By an acceptable lump sum proposed from the Contractor. 3) By force account paid for in the following m~~er: a) For all labor and foreman in the direct change of the specific 'Nork, the Contractor will receive the actual wages paid for each and every hour that said labor and foreman are actually engaged in such work, plus the cost of bond, insurance, and taxes allowable to such wage cost, to which cost shall be added 15% of the sum thereof. No charge shall be made by the Contractor for organization or overhead expenses. b) For all materials used the Contractor will receive the actual cost of such materials including freight charges as shown by original receipted bills, to which cost shall be added ten (10%) percent of the sum thereof. 1'mere materials are not specifically purchased for IlForce Account II i'JOrk, but are taken from the Contractor t s stock, the Contractor shall submit an affidavit of the quantity, price and freight on such materials in lieu of original bills, and invoices. Tnis affidavit shall be approved by the Engineer. c) For any machinery, trucks, or equipment including fuel and lubricants, which it may be deemed necessary or desirable to use, the Contractor will receive a reasonable rental price, for each and every hour that said machinery, trucks and equipment are in use on such work, and to which sum no per- centage will be added. Such rental price shall not exceed the rates established by the A.G.C. for this district for com- par.able rentals and shall be subject to the E.71gineers t approval. - 9 - GC d) The compensation as herein provided shall be received by the Contractor as payment in full for work done by "Force Accountll and said fifteen (15%) percent for labor and said ten (10%) percent for materials shall be agreed to cover profit, superintendence, general expense, overhead, bond premiums, insurance and the use of small tools and equipment for which no rental is allowed. e) The Contractor or his representative and the Engineer or his representative shall compare records of work on a "Force Account" basis at the end of each day. Copies of the records shall be made in triplicate on tlForce Accountll forms, pro- vided for this purpose by the Engineer and signed by both parties. To all,such claims for Force ACCOQDt Work, the Contractor shall attach receipted bills for, or affidavits of, materials used and freight receipts covering freight on such materials used, and said claims shall be presented to the Engineer for payment not later than the twentieth (20) day of the month following that in which the work was actually performed and shall include all labor charges and material charges insofar as they can be verified. Should the Contractor refuse or fail to execute the work as directed, or to submit his claim as required, the Owner may with- hold payment of all current estimates QDtil the Contractorfs refusal or failure is eliminated, or after giving the. Contractor dueT notice the Ovmer may make payment for said work ona basis of a rieasonable estimate of the value of the work performed. 20. CLAIMS AND PROTESTS If the Contractor claims that a.ny instructions by drmvings or otherwise to be unfair or involve extra cost under this contract for which he would claim extra compensation, he shall give the Engineer written notice thereof within a reasonable time after the receipt of such instructions, and in any event before pro- ceeding to execute the work, except in emergency endangering life or property, and the procedure shall then be as provided for changes in the work. No such claL~ will be valid unless so made. 21. SUPERINTENDENCE AIm SUPERVISION The Contractor shall keep on his work during its progress a compe- tent superintendent and any necessary assistants, all satisfactory to the Engineer. The superintendent shall not be ,changed except with the consent of the Engineer Qnless the superintendent proves unsatisfactory to the Contractor and ceases to be in his employ. The superintendent shall represent the Contractor in his absence, and all directions given to him shall be as binding as if given to the Contractor. Important directions shall be confirmed in writ- ing to the Contractor. Other directions shall be so confirmed on written request in each case. - _10 - GC The Contractor shall give efficient supervision to the work, using his best skill and attention, shall carefully study and compare all dravdngs , specifications and other instructions and shall at once report to the Engineer any error, inconsistency, or omission which he may discover, but he shall not be held responsible for their existence or discovery. The Contractor will be supplied, by the Engineer, copies of the Plans and Specifications. He shall have said Plans and Specifica- tions available on the work, at all times, during the prosecution of the \'lork. He shall give the work his constant attention to facilitate the progress thereof and shall cooperate with the Engineer in setting and preserving stakes, bench marks, etc., and in all other things that are necessary for satisfactory completion of the work contemplated. 22. ENGINEER'S STATUS The Engineer shall have general supervision and direction of the work. He is the agent of the Owner only to the extent provided in the contract documents and as authorized by law. He has authority to stop the work whenever such stoppage may be necessary to insure proper execution of the contract. He is recognized by both parties to the contract as the interpreter of the contract documents. He shall, within a reasonable time, make decisions on all claims of the Owner, or the Contractor, on all matters relating to the execution and progress of the work, or the interpretation of the contract docu..ments. The Engineer shall decide any and all questions as -to quality of material furnished for the \'lork, and shall decide all questions regarding the interpretations of specifications or plans relating to the work, and shall determine the amount and quantity of the several kinds of work performed, ~~d materials furnished, which are to be paid for under the contract. Any work not specifically specified on the plans, but which may be fairly implied, or understood, as included in the contract, shall be done by the Contractor without extra charge, and the Engineer shall be permitted to make such corrections and interpretations as may be deemed necessary for the fulfillment to the extent of the plans and specifications. In the case of any discrepancy occuring between the plans and specifications, the decision of the Engi- neer is final. 23. INSPECTION OF WORK The Engineer and his representatives shall at all times have access to the work wherever it is in preparation or progress, and the Contractor shall provide proper facilities for such access and for inspection. An inspector may be stationed on the work to report to the Engi- neer as to the progress of the work and the m~~ner in which it is performed, also to report when it appears that the materials fur- nished, or the work performed by the Contractor fail to fulfill the requirements of the contract and to call to the attention of - 11 - GC the Contractor any such failure or infringement. In case of any dispute arising between the Contractor and the Inspector as to the material furnished, or the manner of performing the work, the Inspector shall have the authority to reject materials or suspend the work until such matter can be referred to, and decided by the Engineer. No advice which the Inspector may give the Contractor shall be construed as binding upon the Owner nor \'Jill such advice release the Contractor from the fulfillment of the terms of the contract. If the specifications, the Engineer's instructions, laws, ordi- nances, or any public authority require any work to be specially tested or approved, the Contractor shall give the Engineer timely notice of its readiness for the.inspection, and if the inspection is by another authority than the Engineer, of the date fixed for such inspection. Inspections by the Engineer shall be promptly made ~nd where practicable at the source of supply. If any.work shall be covered up without approval or consent of the Engineer, it must, if required by the Engineer, be uncovered for examina- tion at the Contractor's expense. Re-examination of questioned work may be ordered by the Engineer, and if so ordered, the \',wrk must be uncovered by the Contractor. If such vwrk be found in accordance with the contract documents, the OWner shall pay the cost of re-ex~rnination and replacement. If such work be found not in accordance with the contrac.t docu- ments, the Contractor shall pay such cost unless he shall.show that the defect in the \'Jork VIas caused by another Contractor, in which event the OWner shall pay the cost. 24. DELAYS AND EXTENSION OF TIME If the Contractor be delayed at any time in the progress of the \'wrk by any act or neglect of the Q\-'mer or the Engineer or any employee of either, or by any other Contractor employed by the OVmer, or by changes ordered in the work, or by strike, fire Qnusual delay in transportation, unavoidable casualties or other causes beyond the Contractor's control, or by any cause which the Engineer shall decide to justify the delay, then the time of completion shall be extended for such reasonable time as the Oi-'Jner may decide, and the decision of the Owner shall be binding on both parties and shall not be arbitrary or Qnreasonable. No such extension shall be made for delay unless claim therefore is made in writing to the Engineer within seven (7) days after the period of delay shall have cow~enced. The Contractor shall not be entitled to extension of time for each one of several causes of delay operative concurrently, but only for the actual period of delay, nor shall the Contractor be entitled to an extension for causes of delay if one of such causes for which extension is authorized above. The Contractor shall have no claim for damages against the Owner for delay in performance of the contract due to any act or omission of the Oi-'Jners or any of its representatives, and his sole remedy on account thereof shall - 12 - GC be his right to apply to the Engineer for extension of time as provided herein. 25. CORRECTION OF WORK BEFORE FINAL PAU1ENT The Contractor shall promptly remove from the premises all mate- rials condemned by the Engineer as failing to conform to the contract, whether incorporated in the work or not and the Contrac- tor shall promptly replace and re-execute his own work in accord- ance with the contract documents and without expense to the ~~ner and shall bear the expense of making good all work of the other Contractors destroyed or damaged by such removal or replacement. All materials not conforming to the requirements of these specifi- cations shall be considered as defective and all such materials, whether in place or not, will be rejected and shall be removed immedia tely from the right-of-i'JaY, unles s othervlise permitted. No material which has been rejected, the defects of which have been corrected or removed, shall be used until approval has been given. If the Contractor does not remove such condewned work and materials within a reasonable time fixed by written notice, the <ftmer may remove them ~~d may store the material at the expense of the Contractor. If the Contractor does not pay the expense of such removal within ten (10) days thereafter, the Owner may upon ten (10) days written notice sell such materials at auction or at private sale and shall account for the net proceeds thereof, after deducting all the costs and expenses that should have been borne by the Contractor. 26. CORRECTION OF \'lORK AFTER FI:NAL PAYi\1ENT Neither the final certificate, nor payment, nor any provision of the contract docl~ents, shall relieve the Contractor of respon- sibility for faulty material or vlOrkmanship, and unless otherwise specified he shall remedy any defects due thereto and pay for ~DY damage to other work resulting therefrom which shall appear within a period of one year from the date of final approval and acceptance by the Ovmer. ~le ~lner shall give notice of observed defects with reasonable promptness. All questions arising under this article shall be decided by the Engineer. 27. FAILURE TO COMPLETE WORK ON TI~m The Contractor guarantees that he can and will complete the work within the time limit stated in the Agreement, or 'Y'li thin the time as extended as provided elsewhere in the contract docw~ents. Inasmuch as the damage and loss to the Owner which will result from the failure of the Contractor to complete the work within the stipulated time, will be most difficult or impossible of accurate assessment, the damage to the Owner for such delay and failure on the part of the Contractor shall be liquidated at a daily rate in an amount as specified in the Special Provisions for each calendar day, Sundays and holidays included, by which the Contractor shall fail to complete the work or any part thereof in - 13 - GC accordance with the provisions hereof~ and such liquidated damages shall not be considered as a penalty. The ~~ner will deduct and retain out of any money due or become due hereunder the amoQnt of liquidated damages~ and in case those amounts are less than the amount of liquidated damages the Contractor shall be liable to pay the difference upon demand. Permi tting the Contractor to continue and finish the 'Y'lork or any part of it after the time fixed for its completion, or after.. the date to which the time for completion may have been extended, shall in no way operate as a waiver on the part of the ~~ner of any of its rights under the contract. Neither by the taking over of the work by the O'wner, nor by the ter.mination of the contract, shall the O'wner forfeit the right to recover liquidated damages from the Contractor or his Surety for failure to complete the contract. 28. THE RIGHT O'F THE OVJNER TO' DO' THE "TORI\: If the Contractor should neglect to prosecute the work properly, or fail to perform any provision of the contract, the O'wnerafter three (3) day's written notice to the Contractor, may without prejudice to any other remedy the ONner may have, make good such deficiencies and may deduct the cost thereof from the payment then or thereafter due the Contractor, provided, however, ..that the Engineer shall approve both such action and the amount charged to the Contractor. 29. RIGHT O'F THE O'WNER TO' DECLARE CO'NTR4CTO'R IN DEFAULT In addition to those instances specifically referred to in other articles herein, the O'wner shall have the right to declare the Contractor in default of the whole or any part of the work if: 1) The Contractor becomes insolvent; or if 2) The Contractor makes an assignment for the benefit of creditors pursuant to the statutes of the State of Minnesota; or if 3) A voluntary or involQntary petitiori in bankruptcy be filed by or against the Contractor; or if 4) The Contractor fails to commence work when notified to do so by the Engineers; or if 5) The Contractor shall abandon the work; or if 6) The Contractor shall refuse to proceed with the work when and as directed by the Engineer; or if 7) The Contractor shall without just cause reduce his working force to a number \\!hich, if maintained, would be insufficient, in the opinion of the Engineer, to complete the work in accord- ance 'VJi th the approved Progress Schedule ~ and shall fail or - 14 .. GC refuse sufficiently to increase such working force when ordered to do so by the ~1gineer; or if 8) The Contractor shall sublet, assign, transfer, conveyor otherwise dispose of his contract other than as herein specified; or if 9) A receiver or receivers are appointed to take charge of the Contractor's property or affairs; or if 10) The Engineer shall be of the opinion that the Contractor is or has been wilfully or in bad faith violating any of the provisions of this contract; or if 11) The Engineer shall be of the opinion that the Contractor is or has been unnecessarily or unreasonably or wilfully delay- ing the performance and completion of the work, or the award of necessary sub-contracts, or the placing of necessary material and equipment orders; or if ~) The Engineer shall be of the opinion that the work cannot be completed within the time herein provided therefore or within the time to which such completion may have been extended; provided, however, that the impossibility of timely completion is in the Engineer's opinion, attributable to conditions within the Contractors' control; or if 13) The Engineer shall be of the opinion that the Contractor is not or has not been executing the contract in good faith and in accordance with its terms; or if 14) The work is not completed within the time herein provided therefore or within the time to which the Contractor may be entitled to have such completion extended. 15) Before the Owner shall exercise its right to declare the Contractor in default by reason of the conditions set forth in items numbered 1), 4), 5), 6), 7), 10), 11), 12), 13) and 14), he shall give the Contractor an opportunity to be heard, on two days' notice at which hearing the Contractor may have a stenographer present; provided, however, that a copy of such stenographic notes, if any, shall be furnished to the Owner. 30. EXERCISE OF THE RIGHT TO DECT,~~E IN DEFAULT The right to declare in default for ~DY of the grounds specified or referred to in Article 29 hereof, shall be exercised by send- ing the Contractor a notice, signed by the Engineer, setting forth the ground or grolli~ds upon which such default is declared. 31. QUITTING THE SITE Upon receipt of such notice the Contractor shall immediately dis- continue all further operation under this contract and shall - 15 - GC immediately quit the site~ leaving untouched all plant materials~ equipment~ tools and supplies then on the site. 32. COMPLETION OF ~tlE WORK AFTER DEFAULT The OWner~ after declaring the Contractor in default, may then have the work completed by such means and in such manner, by contract with or without public letting, or otherwise, as it may deem advisable, utilizing for such purpose such of the Contrac- tor's plant, materials, equipment, tools and supplies remaining on the site, and also such sub-contractors as it may deem advisable. After such completion, the Rngineer shall make a certificate stat- ing the expense incurred in such completion, which shall. include the cost of reletting and also the total amount of liquidated damages (at the rate provided for in the Specifications) from the date when the work should have been completed by the Contrac- tor in accordance with the terms hereof to the date of actual completion of the work. Such certificate shall be binding and conclusive upon the Contractor, his Sureties, and any person claiming under the Contractor, as to the amount thereof. The expense of such completion, as so certified by the Engineer shall be charged against and deducted out of such monies as would have been payable to the Contractor, if he had completed the work; the balance of such monies, if any, subject to the..other provisions of this contract, to be paid to the Contractor without interest after such completion. Should the expense of such com- pletion, so certified by the Engineer, exceed the total>sum which would have been payable under this contract if the same had been completed by the Contractor, any such excess shall be paid by the Contractor to the (ftmer upon demand. 33. PARTIAL DEFAULT In case the Owner shall declare the Contractor in default as to a part of the work only~ the Contractor shall discontinue such part, shall continue performing the remainder of the work in strict conformity with the terms of the contract, and shall in no way hinder or interfere with any other Contractors or persons whom the (ftJner may engage to complete the work as to which the Contractor was declared in default. The provisions of the clauses herein relating to declaring the Contractor in default as to the entire work shall be equally applicable to a declaration of partial default, except that the Owner shall be entitled to utilize for completion of the part of the work as to which the Contractor was declared in default only such plant, materials, equipment, tools and supplies as had been previously used by the Contractor on such part. 34. SCOPE OF PA~~ENT The Contractor shall receive and accept'the compensation as herein provided, in full payment for furnishing all materials, labor, tools, equipment, royalties, fees, insurance, permits, - 16 - GC bonds, etc., and for performing all work contemplated and embraced under the Contract, also for all loss or damage aris- ing out of the nature of the work, or from the action of the elements, until its final acceptance by the OWner, and for all risks connected with the prosecution of the work, also for all expenses incurred by, or in consequence of, the suspension or discontinuance of said prosecution of the work as herein speci- fied and for completing all of the work embraced in the Contract. The Contractor shall under this contract price furnish and pay for all material and incidental work, furnish all accessories, and do everything which may be necessary to carry out the contract in good faith, which contemplates everything completed in good working order, of good material ,with accurate worlunanship. 35. APPLICATION FOR PAYMENTS The Contractor shall submit to the Engineer an application for each payment verified as required by law for claims against the ~1ner, and, if required, receipts or other vouchers showing his payments for materials and labor, including payments to sub- contractors. Application for progress payments authorized by the contract shall be submitted at least twenty (20) days before each payment falls due and, if required, the Contractor shall before the first application, submit to the Engineer a schedule of values of the various parts of work, including the quantities aggregating the total sum of the contract divided so as to facilitate payments to sub-contractors, made out in such form, and supported by such evidence as to its correctness as the K~gineer may direct. In applying for pa~~ents the Contractor shall submit a statement based upon this schedule, supported by such evidence as the Engineer may direct, showing his right to payment claimed. Payment claimed on account of materials delivered and suitably stored at the site, but not incorporated in the work, shall, if required by the Engineer, be conditioned upon submission by the Contractor of bills of sale, or such procedure as will establish the title of the ~vner to such material, or otherwise adequately protect the interest of the Owner. The Engineer will examine claims for payment promptly, and his determination of the amo~~t due on progress pa~~ent will be final. 36. PARTIAL PAYMENTS Unless payments are withheld by the Owner for reasons hereinbe- fore stated, payment will be made at least once a month on a basis of ninety (90%) percent of the work done, provided the work is progressing to the satisfaction of the Engineer. Monthly estimates may include the value of acceptable materials required in the construction, which have been delivered on the site of the work or adjacent railway siding, and for i'Jhich acceptable provisions have been made for their preservation and storage. From the total value of the materials so reported, ten (10%) percent will be retained. Such material, when so paid - 17 - GC for by the ~vner, shall become the property of the (WIner, and in the .event of the default on the part of the Contractor, the Owner may use or cause to be used such materials in the construction of the \'wrk provided for in the contract. The amount thus paid by the ~1ner for materials shall go to reduce estimates due the Contractor as the material is used in the 'Work. Vouchers will be passed for payment by the (WIner not later than the tenth (loth) of the following month, unless delayed by require- ments for examination or auditing by other authorities. 37. CERTIFICATES OF PATI4ENT If the Contractor has made application as above, the Engineer shall, not later than the date ~hen each payment falls due, issue to the Contractor a certificate for such amount as he decides to be properly due. No certificate issued nor payment made to the Contractor, not partial, or entire, use, or occupancy of the work by the ~lner, shall be acceptance of the work or materials not in accordance with this contract. 38. PAY14ENTS ~HTHHELD The Owner may withhold, in addition to retained percentages, from payment to the Contractor such an amount or ~mounts as may be necessary to cover: 1) Defective work not remedied. 2) Claims for labor or materials furnished the Contractor or sub-contractor, or reasonable evidence indicating probable filing of such claims. 3) Failure of the Contractor to make payments properly to sub- contractors or for material or labor. 4) A reasonable doubt that the contract can be completed for the balance then unpaid. 5) Evidence of damage alleged to be caused by the Contractor to other persons or property in connection with the work under the contract for which claim has been or will be asserted against the Contractor, the ~1ner or the Engineer. The awner may disburse and shall have the right to act as agent for the Contractor in disbursing such funds as have been with- held pursuant to this paragraph to the party or parties who are entitled to payment therefrom, but the Owner assumes no obligation to make such disbursement. The Owner will render to the Contractor a proper accounting of all such funds dis- bursed. 39. FINAL INSPECTION Tne RDgineer will make final inspection of all work included in - 18 - GC the Contract or any portion thereof, as soon as practicable after notification by the Contractor that such work is nearing comple- tion. If such work is not acceptable to the Engineer at the time of his inspection, he will advise the Contractor in writing as to the particular defects to be remedied before such work can be accepted. If, within a period of ten (10) days after such notification, the Contractor has not taken steps to speedily complete the work as directed, the Engineer may, without further notice and without in any way impairing the contract, make such other arrangements as he may deem necessary to have such work completed in a satisfactory manner. The cost of so completing such work shall be deducted from any monies due, or "Vlhich may become due the Contractor on his contract. 40. FINAL PAYMENT Upon completion of the vvork and its acceptance by the Engineer, the Engineer will prepare a final estimate containing complete quantities of each and every item of work performed by the Contractor, and the value thereof, upon acceptance of said final estimate by the Contractor, the Engineer will certify in writing to the Owner as to the completion and his acceptance of the work, and to the entire amount and value of each and every item of work performed in accordance with the terms of the contract. Unless as herein provided, the Owner will accept the Certificate and Final Estimate for final payment and will notify the Contrac- tor and his Surety or Sureties of the acceptance of the work. T0e action of the OvJner and the Engineer, by which the Contrac- tor is to be bOQnd and the contract concluded according to the terms thereof, shall be evidenced by the aforesaid Certificate and Final Payment. All prior certificates or estimates upon which payments may have been made are merely partial estimates and subject to correction in the final payment. Before final payment is made for the vlOrk on this Project, the Contractor must make a satisfactory showing that he has com- plied with the provisions of Minnesota Statutes Annotated 290.92 requiring the withholding of state income tax for wages paid employees on this Project. Receipt by the Clerk of the ~wner of a Certificate of Compliance from the Comrnissioner of Taxa- tion will satisfy this requirement. The Contractor is advised that before such certificate can be issued, he must first place on file with the Co~nissioner of Taxation an affidavit that he has complied with the provisions of M.S.A. 290.92. The required affidavit form will be supplied by the Co~~issioner of Taxation, Centennial BUilding, st. Paul, Minnesota 55101, on request. Final payment 't'lill not be made until the Contractor shall have filed with the Owner evidence in the form of an affidavit and such other evidence as may be required that all claims against him by reasons of the contract have been fully paid or satis- factorily secured. In case such evidence is not furnished, the Ovmer may retain out of any amount due said Contractor SUi'IlS sufficient to cover all claims unpaid. - 19 .n GC 41. NO WAIVER OF LEGAL RIGHTS The Owner, or its Engineer, shall not be precluded or stopped by any measurement, estimate or certificate, made or given by them, or by any of their agents or employees, under any provision or provisions, of the Contract, any time either before or after the completion and acceptance of the work and payment thereof pursuant to any measurements, estimate or certificate, from showing at any time, that any such measurements, estimate or certificate is untrue or incorrectly made in any particular or that the work or materials or any part thereof do not conform in fact to Specifica- tions and Contract, and the Owner shall have the right to reject the whole or any part of the aforesaid work or material, should the said measurement, estimate, certificate or payment be found, or be known to be inconsistent with the terms of the Contract, or otherwise improperly given, and the Olmer shall not be pre- cluded or stopped notwithstanding any such measurement, estimate, certificate and payment in accordance herewith, from demanding and recovering from the Contractor and his Surety such damages as it may sustain by reasons of his failure to comply with the terms of the Specifications and Contract. Neither the acceptance of the Owner or its Engineer or any of their agents or employees, nor any certificates by the Engineer, for payment of money, nor any pa;yment for, nor acceptance,6f the whole or any part of the work by the Owner, or its Engineer, nor any extension of time, nor any possession taken by the O~mer or its employees, shall operate as a waiver of any portion Of the Contract or any power herein reserved by the Owner, or any right to damages herein provided, nor shall any 'waiver of any breach of the Contract be held to be a waiver of any other or subsequent breach. 42. DEFENSE OF CLAIMS OR SUITS The Contractor shall indemnify and save harmless the Owner and all of its officers, agents and employees, from any and all loss, damages, expense, including cost and expense and attorney's fees of litigation arising from all suits, actions, or claims or any character, name and description, brought for, or on account of any injuries or damages received or sustained by any person, or persons or property by or from the said Contractor or by or in consequence of any neglect in safeguarding the work, or through the use of unacceptable materials in constructing the work or by or on account of any act or omission, neglect or misconduct of said Contractor, or by or on account of any claims or amounts recovered for any infringement of patent, trademarks or copy right, or from any claims or amounts arising or recovered under the IlVIorkmen's Compensation La\'lll, or any other la\1, bylaw, ordi- nance, order or decree and so much of the money due the said Contractor under and by virtue of his Contract as shall be con- sidered necessary by the Owner may be retained for the use of said Oi'mer, or in case no money is due his Surety shall be held until such suit or suits, action or actions, claim or claims, for injuries or damages, as aforesaid shall have been settled and suitable evidence to that affect furnished to the Owner. - 20 - GC The unauthorized use by the Contractor of public or private property for any purpose may be considered an injury or damage to the property so used. No monies, payable under the Contract, or any part thereof except the estimate for the first month, or period, shall become due and payable, if the Owner so elects, until the Contractor shall satisfy the said ~lner that he has made a satisfactory settlement for all materials and equipment used in or upon the work and labor done for the preceding month in connection therewith. 43. PATENTED DEVICES, ~~TERIALS ArID PROCESSES If the Contract requires, or the Contractor desires, the use of any design, device, material or process covered by letters, pate~t or copyright, trade mark or trade name, he shall provide for such use by suitable legal agreement with the patentee or Owner and a copy of said agreement shall be filed with the ONner. If no such agreement is made or filed as noted, the Contractor and the Surety shall indemnify and save harmless the ~lner from any and all claims for infringement by reason of the use of any such patented design, device, material or process, or any trade mark or trade name or copyright in connection with the work agreed to be per- formed under the Contract, and shall indemnify the Ovmer for any costs, expenses and damages which it may be obliged to pay, includ- . .:.. expense, and attorney's fees incident to litigation by ~ng cosv, reason of any such infringement, at any time during the prosecu- tion or after the completion of the work. 44. HATERIALS -Unless otherwise specified all materials shall be new, and both workmanship and material shall be of good quality. The Contractor shall, if required, furnish satisfactory evidence as to the kind and quality of materials or tools used by him. The source of supply of the materials to be used shall be approved by the Rngineer before delivery is started. The approval of the source of any material will stand only so long as the material itself conforms to the specifications. Only materials conforming to the requirements of these specifications shall be used in the v-l ork . The source of any material shall not be changed at any time without the written approval of the Engineer. The Contractor may be required at any time to furnish a complete statement of origin, composition and manufacturer of any or all materials required in the work, or to submit samples of the same. Materials shall be stored so as to insure the preservation of their quality and fitness for the work and such materials, even though approved before storage, shall be subject to test and must meet the requirements of these specifications at the time it is proposed to use them in the work. Materials shall be stored in a manner that will facilitate inspection. The portion of the site or right-of-\'lay not required for public travel may, with the consent of the Engineer, be used for storage purposes, and for the placing of the Contractor1s plant and - 21 - GC equipment; but any additional space required, unless otherVlise stipulated, shall be provided by the Contractor at his expense. All materials, supplies, and articles furnished shall, whenever so specified, and otherwise wherever practicable, be the standard stock products of recognized reputable manufacturers. From the commencement of the \'lork until the completion of the saBle, the Contractor shall be solely responsible for the care of the work covered by this contract and for the materials delivered at the site intended to be used in work and all injury or d~nage to the sa~e from whatever cause, shall be made good at his expense before the final estimate is made. He shall provide suitable means of protection for and shall protect all materials intended to be used in the work and all work in progress as well as com- pleted ,'Jerk. He shall take all necessary precautions to prevent injury or damage to the work in progress of construction by flood, freezing or from inclemencies of the weather at any and all times and only approved methods shall be used for this purpose. 1Vben tests of materials are necessary, such tests shall be made by and at the expense of the Contractor unless otherwise provided. The Contractor shall afford such facilities as the Engineer may require for collecting and forwarding samples, and shall not use the materials represented by the samples until tests have been made and the materials have been found to satisfy the requirements of th~se specifications. The Contractor in all cases shall furnish tharequired samples without charge. All materials not conforming to the requirements of these specifi- cations shall be considered as defective ~~d all such materials, \'1hether in place or not, will be rejected and shall be removed i~mediately from the right-of-way, Q~less otherwise permitted.

LAYING OF PIPE Proper implements, tools, and facilities satisfactory to the Engineer shall be provided and used by the Contractor for the safe and convenient prosecution of the work. Pipe and materials shall be unloaded and distributed on the job in a manner approved by the Engineer. In no case shall mater- ials be thrown or dumped from the truck. Before lowering and while suspended, the pipe shall be inspected for defects to detect any cracks. Any defective, damaged or unsound pipe shall be rejected.. All foreign matter or dirt shall be removed from the inside of the pipe before it is lowered into its position in the trench, and shall be kept clean by approved means during and after lay- ing. All openings along the line of the sewer shall be securely closed as directed, and in the suspension of wor~ at any time, suitable stoppers shall be placed to prevent earth or other sub- stances from ent~ring the sewer. Pipes shall be laid to a true line and at uniform rates of grade between manholes as shown on the Plans. Fine grading, to the bottom of the barrel, shall proceed ahead of the pipe laying, and should any over-excavation exceeding two (2) inches be en- .J.. ' the material added shall be moistened and compacted counlJerea, to the satisfaction of the Engineer, or foundation material shall be added at the expense of the Contractor. Holes shall be dug for the pipe bells, and the material placed at the middle of the preceding pipe laid. The pipe shall be supported for the bottom 90 degrees and throughout its length (except for the minimum distance necessary at the bell holes) as shown on the Plans. Bell holes shall be adequate to make the joint, but no larger than necessary so that maximum support on undisturbed ground will be provided for the pipe. The remain- der of the pipe shall be surrounded to a height of at least six (6) inches above its top by granular materials, shovel placed and hand tamped, to fill completely all spaces under and adja- cent to the pipe. Pipe laying shall proceed upgrade with the spigot ends pointed in the direction of flow. No pipe shall be laid in \tlater or \lIhen the trench conditions are urlsui tab Ie for such \twrk, except by written permission of the Engineer. The Contractor shall make all connections of pipe to the manholes \llhich hav'e previously been constructed. He shall recei ve no extra compensation for connection to capped stubs or cutting into present manholes. For completing drop sections for drop manholes, the Contractor shall be paid as per unit price bid. - 11 - SC-SS 12. A. Be 13. Granular material, or other suitable material as determined by the Engineer, free from rocks and boulders, shall be deposited in the trench simultaneously on both sides of the pipe for the full width of the trench to a height at least six (6) inches above the top of the pipe, shovel placed and hand tamped to fill completely all spaces under and adjacent to the Pipe. In the event that natural, suitable, gransular material is not encountered during the normal excavation of the sewer trench, or when the material encountered is detennined unsuitable by the Engineer, for backfilling around the pipe as required above; the Contractor shall provide and place such approved material. The Contractor shall furnish approved material from surplus material obtainable from other excavation on the project, within a haul distance of two (2) miles one way, at no additional com- pensation. If suitable material is not available as stated above, the contractor shall purchase backfill material for backfilling around the pipe. The Contractor shall be uaid for only that backfill material required for filling or backfilling as he may be directed to purchase and place by the Engineer. All quantities of such material used shall be verified by the Engineer. Succeeding layers of backfill may contain coarse materials, but shall be free from pieces of rock, frozen material, concrete !J roots, stumps, tin cans, rubbish and other similar articles whose presence in the backfill, in the opinion of the Engineer, would cause excessive settlement of the trench, or damage to the pipe. \iherever select material, that exists in place in the upper four (4) feet of the finished grade of the paved or traveled portions of the street or roadway, is removed by the trench excavation, the Contractor shall replace said material (or material of equal quality) as backfill in the upper four (4) feet of the finished grade. \'mere select material does not exist in place as des- cribed above, the Contractor shall provide and place sufficient select backfill to stabilize the finisr-;ed grade from surplus material obtainable from other excavatio~-l on the nroject, '\:'JitL:Ln a haul distance of two (2) miles one way at no additional com- pensation. Backfilling shall be done in lifts of uniform layers not to ex- ceed the depth shown in the compaction cfJart and each lift shall be completely compacted over the full width of the excavated area. Compacting shall continue until no more settlement occurs. Three feet of material over the top of tte pipe shall be re- quired before a vibratory or sheepsfoot roller may be used. -13- Sc-ss Plate Plate No waste material or debris In all cases, the Contractor shall blade and compact the road- way after the trench has been backfilled, so that it shall be passable to traffic at all times. The Contractor shall maintain the roadway in a condition acceptable to the Engineer at all times until final acceptance of the entire work by the City. Therefore., the Contractor shall provide one motor grader which shall be available to the project at all times for surface maintenance. If, in the opinion of the Engineer, the Contractor is not maintaining street surfaces sufficiently '\'lith one motor grader, he shall provide additional motor graders. The Contractor shall also blade and maintain all detours and by- passes. All maintenance work shall be done at no additional CO:::l- pensation. In addition to the blading and maintenance requirements specifiej, the Contractor shall provide at least one tank truck with pres- surized spray bars for spraying water on the streets to control the dust. Dust control shall be required, as necessary, on all streets after compaction and grading, and on all detours or by- passes. Payment for dust control shall be as specified in Article 21R. The Contractor shall remedy at his own expense any defects that appear in the backfill for a period of one year following com- pletion. 14. RESTOPATION OF SURFACE Wherever the surface of the ground is removed or disturbed by the Contractor1s operation, the Contractor shall restore, replace or rebu:i.ld all such surfaces to a condition at least equal to its condition at time of removal. Blading and maintaining of streets and roadvfays are covered by Article 13, 'IBackfilling and Grading 11 of these Standard Specificat :Lons. If the ali~Lment of the sewer and its appurtenances, as shown 0:::1 the Plans, is alongside or parallel to a paved roadway, but the proximity of such alignment to the paving does not warrant damage or removal of such paving, the Contractor shall replace O~ repair the paving \'1hich he has removed or damaged at no addi t im:.- al compensation. Hhen the alignment of the sevier and its appur- tenances lies within a paved roadway, the Contractor shall re- place or repair any pavement \'1hich is damaged or removed as spec- ified in the Special Provisions. 15.

All house connections shall be capped by a clay stopper, sealed firmly in place, or by other methods approved by the Engineer, which will effectively prevent water from entering the sewer until the connection is placed in service. The Contractor shall provide all necessary vrges or tees for connecting services to sewer lines at the Contract unit prices. Six (6) inch bends shall be provided to bring services ta proper location and elevation, at no additional compensation. At the end of all house connections, located at the pro- perty line, the Contractor shall furnish and set at no additional compensation, a 2-inch by 2-inch, long wooded stake, set vertically from the service pipe to the ground surface. In undeveloped areas this stake shall extend twelve (12) inches above the ground surface. 17. tffiIfHOLES AND CATCH BASINS Excavation sLall be to a depth and size to provide for construc- tion of the manhole or catch basin as shown in detail on the Plans. Concrete base shall be of size and depth as shown on the Plans. Concrete used shall have a 28-day compressive strength of at least 3,000 pounds per square inch. Material used for this pur- pose shall be subject to the approval of the Engineer. Base shall be poured on undisturbed earth. Walls shall be of a pre- - and shall be neatly grouted cast concrete as shovm on the Plans, to form a completely watertight manhole. Precast concrete bases may be used when approved by the Engineer. Precast base must be placed on a minimum of 6 inches of granular material itihiell has been thoroughly compacted and leveled off across the entire width of the base. Frames and covers shall be set to the designated elevation in a full mortar bed. - 17 - SC-SS In addition to the infiltration test, exfiltration tests will be required on sewer lines which are above the present ground water. The test section shall be bulkheaded and the pipe subjected to a hydrostatic pressure produced by a head of water at a depth of four (4) feet above the bottom invert of the sewer ill1der test at its lower end. This head of water shall be maintained for a period of one hour during which it is presumed that full absorption of the pipe bOdK has taken place, and thereafter for a further period of four ( ) hours for the actual test of leakage. During this four (4) hour period$ the measured loss shall not exceed that specified above for infiltration. The introduction of any substance into the water used for testing with the intent to seal such leaks as may be indicated will not be permitted. Two such exfiltration tests will be required for each type of pipe and for each size of pipe. If the results are satisfactory on the two sections chosen by the Engineer, no further exfiltra- tion tests will be required. If results of the exfiltration test are not satisfactory, add tional tests may be required until the Engineer is satisfied that the leakage requirements are being met. Prior to final acceptance of each section of the sewer line, t~e Contractor shall flush a ball, the full diameter of the sewer, through the line. All dirt and debris shall be prevented from entering the existing sewer system by means of watertight plugs or other suitable methods. Upon completion of the Contract, the Engineer will carefully inspect all sewers and appurtenances. Any cracked or broken pipe shall be removed and replaced with a sound one and the in- vert of the sewer shall be left clean and free from any obstruc- tions throughout the entire line. 19.

Hydrants must maintain their position and must not be knocked out of plwnb during backfilling. D. Val'ves ., Boxe s , Hanholes, Vaults and Fittings Val ves and fittings shall be placed i'ihere shoVln m the plans or as designated by the Engineer. Jointing shall be done as previously specified hereino Unless otherwise specified or shoi'm on the drawings, cast iron valve boxes shall be installed with all gate valves 12 inches or smaller and all butterfly valves and ball valves. Valve boxes shall be firmly supported to maintain -17- SC-H centered and plumb alig~ment over the wrench nut of the valve, with box cover flush with the surface of the finisned pavement or at such other level as may be directed by the Engineer. All geared valves and such other valves as may be designated shall be set in masonry valve manholes or vaults with the wrench nuts readily accessible for operation through the man- hole openings. Manholes shall be constructed in a manner that will permit minor valve repairs and to afford protection to the pipe from impact where it passes through the manhole or vault "TalIs. E. Building Services Curb stops and boxes shall be installed as shown on the detail plates in the Appendix. The curb stop and box shall be located on the property line, unless specified otherwise. Corporation stops shall be tapped into the main only when full of water under pressure. No taps shall be made into a dry pipe. Corporation stops shall be turned into the pipe until tight and shall not be turned back to facilitate having the operating nut on the top. Tne copper service lines as placed between the water mains and the curb boxes shall have a minimQm of 7.5 feet of cover; therefore service lines must be placed (incidental to the project) beneath any obstruction which would prohibit the required cover if the service line was placed on top of said obstruction. The method of tunneling under an obstruction shall be approved by the Engineer. 17. BACKFILLING AND GRA~ING All excavation in trenches shall be backfilled to the original ground surface or to such grades as specified or shOi-'ln on the draviings. The backfill shall begin as soon as practical after the pipe has been placed and shall thereafter be carried on as rapidly as the protection of the balance of the work will permit. Complete cleanup shall proceed directly behind the backfilling to accommodate the return to normal conditions. Should the Contractor, in the Engineer's opinion, fail to diligently pursue the backfilling and cleanup, the amount of work on which complete cleanup has not been accomplished shall be limited to 1,000 lineal feet for the entire job. Tne Contractor shall have sufficient equipment on the job to assure timely backfill and cleanup at all times. -18- SC-H Backfilling and compacting shall be done as thoroughly as pos- sible so as to prevent after settlement. Depositing of the backfill shall be done so the shock of falling material will not injure the pipe or structures. Grading over and around all parts of the work shall be done as directed by the Engineer. Granular material, or other suitable material as determined by the Engineer, free from rocks and boulders, shall be deposited in the trench simultaneously on both sides of the pipe for the full width of the trench to a height at least six (6) inches above the top of the pipe, shovel placed and hand tamped to fill completely all spaces under and adjacent to the pipe. In the event that natural, suitable, granular material is not encountered during the normal excavation of the trench~ or when the material encountered is determined unsuitable by the RDgineer, for backfilling around the pipe as required above; the Contractor shall provide and place such approved material. The Contractor shall furnish approved material from surplus material obtainable from other excavation on the project, within a haul distance to two (2) miles one way, at no additional com- pensation. If suitable material is not available as stated above, the Contractor shall purchase suitable pit run material for backfilling around the pipe. The Contractor shall be paid for only that select material re- quired for filling or backfilling as he may be directed to pur- chase and place by the Engineer. All quantities of such material used shall be verified by the Engineer. Succeeding layers of backfill may contain coarse materials, but shall be free from pieces of rock, frozen material, concrete, roots, stumps, tin cans, rubbish and other similar articles whose presence in the backfill, in the opinion of the Engineer, would cause excessive settlement of the trench, or damage to the pipe. vmerever select material, that exists in place in the upper four (4) feet of the finished grade of the paved or traveled portions of the street or roadway, is removed by the trench excavation, the Contractor shall replace said material (or material of equal quality) as backfill in the upper four (4) feet of the finished grade. ~fuere select material does not exist in place as des- cribed above, the Contractor shall provide and place sufficient select backfill to stabilize the finished grade from surplus material obtainable from other excavation on the project, within a haul distance of two (2) miles one way at no additional com- pensation. -19- Sc-w Backfilling shall be done in lifts of uniform layers not to ex- ceed the depth shown in the compaction chart and each lift shall be completely compacted over the full width of the excavated area. Compacting shall continue until no more settlement occurs. Three feet of material over the top of the pipe shall be re- quired before a vibratory or sheepsfoot roller may be used. COMPACTION CFART Maximum Loose Soil Lift Height (Ft. ) Compactor Type Sands Plastic Soil Vibratory Roller (Vibro-Plus CK-ll) or equal 4.0 Not allowed Sheepsfoot (150 PSI Minimum) Not allowed 2.0 Button Head PneQmatic 0.5 0.5 Plate Tamper 1.0 1.0 Plate Vibrator 1.0 Not allowed Special compaction shall be done around all manholes, catch basins, valve boxes, curb boxes) and other structures) and utilities by the use of pneumatic tampers) plate tampers) or plate vibrators with lifts not to exceed that shown in the COMPACTION Ca~RT. Hydrant leads and water service trenches must be compacted in the same manner as the water main trenches. They shall not be left open overnight. Dl areas where curb and gutter exists) sufficient curbing shall be removed to allow this compaction over the entire disturbed area. All deficiencies in the quantity of material for backfilling the trenches or for filling depressions caused by settlement shall be supplied by the Contractor. Any excess suitable material shall be hauled away and deposited and leveled where directed by the Engineer at no additional compensation. The haul limit shall not exceed two (2) miles one way. No waste material or debris shall be deposited on any public or private property within the limits of the municipality without the written permission of the Engineer. Waste material and debris shall include) but not be limited to, trees, stumps, pieces of pipe, pieces of concrete, pieces of asphaltic concrete, tin cans, or other waste material from the construction opera- tions. All disposal areas shall be leveled off and the area shall have approximately one (1) foot of clean fill area on the top) all at no additional compensation. -20- SC-W vmen the trench excavation for the water main and appurtenant work is within the right-of-ways of state or County Highways, the backfilling of the trench, compaction of materials, sub- grade preparation and surfacing shall be done in strict accord- ance with the requirements and specifications of the state or County Highway Department at no additional compensation. In all cases, the Contractor shall blade and compact the road- way after the trench has been backfilled, so that it shall be passable to traffic at all times. Tne Contractor shall main- tain the roadway in a condition acceptable to the Engineer at all times until final acceptance of the entire work by the ~1ner. Therefore, the Contractor shall provide one motor grader which shall be available to the project at all times for surface maintenance. If, in the opinion of the Engineer, the Contractor is not maintaining street surfaces sufficiently with one motor grader, he shall provide additional motor graders. The Contractor shall also blade and maintain all detours and by- passes. All maintenance work shall be done at no additional compensation. In addition to the blading and mainten8~nce requirements speci- fied, the Contractor shall provide at least one tank truck with presurized spray bars for spraying water on the streets to control the dust. Dust control shall be required, as necesary, on all streets after compaction and grading, and on all detours or by-passes. Payment for dust control shall be as specified in Article 22, Paragraph P. The Contractor shall remedy at his own expense any defects that appear in the backfill for a period of one year following com- pletion. 18. TESTING AtID DISINFECTING MAINS After the pipe has been laid including fittings, valves, and hydrants and the line has been backfilled in accordance with these specifications, all newly laid pipe, or any valved section thereof, unless otherwise directed by the ~~gineer, shall be subjected to hydrostatic pressure of 150 pounds per square inch. The duration of each such test shall be at least two hours. Water added to maintain the pressure shall not exceed the voll~e per 100 lineal feet of pipe being tested during the two hour test as specified in the following table: -21 SC-W Maximum Allowable Leakage in Pipe Size Gallons/lOO ft. of Pipe/2 Hour Test 611 0.2 gallon 811 and lOll 0.25 gallon 1211 0.35 gallon 16" O~50 gallon Larger than 16'1 .03 gallons/inch of diao Each valved section of pipe shall be slowly filled with water and the specified test pressure, measured at the lowest point of elevation, shall be applied by means of a p~mp connected to the pipe in a satisfactory manner. The pump, pipe connection, gauges and all necessary apparatus shall be furnished by the Contractor. Gauges and measuring devices must meet with the approval of the Engineer and the necessary pipe taps made as directed. 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 elevations, and afterward tightly plugged. ~DY cracked or defective pipes, fittings, valves or hydrants discovered in consequence of the pressure test shall be removed and replaced by the Contractor with sound material in the maD~er provided and the test shall be repeated until satisfactory to the Engineer. Each house service with the corporation cock open, shall be tested hydrostatically with a pressure of 150 pounds per square inch in the water main and service prior to backfilling the excavation. A visual inspection will be made of each service at the corporation cock and at the curb stop while the service is under hydrostatic test. Testing of individual services with the corporation cock closed will not be allo'Vled. All house service-installations shall be completed by 4:00 P.M. each day to permit testing and backfilling of service connections. Testing of house services shall be done with a constant pressure pump to maintain 150 p.s.i. throughout the test. After the installation has been tested, the Contractor shall follow the disinfection procedures as described in paragraphs Nos. 1227 and No. 1228 of Section XII, lIManual of Hater Supply Sanitationll, of the Minnesota Department of Health. The Con- tractor shall become thoroughly informed on the requirements of the above mentioned manual and shall maintain a sufficient n~~ber of copies of smne on the job site. -22- SC-vJ Unless facilities are available for the introduction of either chlorine or heavily chlorinated water directly into the mains on their completion, chlorine disinfectant should be placed at each joint prior to jointing. The following table indicates the amount of calcium hypochlorite (65% available chlorine) that shall be added to each 20 foot length of pipe to furnish a solution containing the minllilum amount of free chlorine. Pipe Size Calcium HJ~ochlorite 65% available chlorine b1i o. oz. 81t 0.8 oz. 12 It 1.5 oZo 16" 2.8 oz. 18 It 4.0 oz. 24" 603 OZo 301t 8.3 oz. 36" 15.0 oz. Only fresh disinfectants shall be used and the main filled with water and flushed not later than one week after the disinfectant has been added. The 1'mter (containing chlorine) shall be left in the pipe, being disinfected, for a minimum of twenty-four (24) hours. An electrical conductivity test shall be in accordance with the follovling procecure. A. Testing Procedure ao The system (pipeline and hydrants) shall be testad for electrical continuity and current capacity. The electrical test shall be made after the hydrostatic pressure':-test and while the line is at normal operating pressure. Backfilling shall have been completed. The line may be tested in sec- tions of convenient length as approved by the Engineer. b. Direct current of 350 amperes, +10%, shall be passed through the pipe line for 5 minutes. Current flow through the pipe shall be measured continuously on a suitable aTILl11ete r and shall remain steady without interruption or excessive fluctuation throughout the 5 minute test period. c. Insufficient current or intermittent current or arcing, indicated by large fluctuation of the ammeter needle, shall be evidence of defective electrical contact in the pipe line. 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. -23- SC-vl B. Notes on Test Procedure a. Sources of D. C. current for these tests may be mdor 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. b. 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 voltage drop. Usuable sizes will probably be in the range of 2/0 to ~ /0 A. vI . G. c. 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. d. A hook-on type D.C. amrneter placed on one of the cables leading to the hydrant is a convenient method of measuring cu rrent. eo In using arc welding machines, the current control should be set at minimum before starting. After starting the machine, advance the control until the current indicated on the aw~eter 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. 19. RESTOR4TION OF GROUND A1ID ROAD SURFACES vfuerever the surface of the ground is removed or disturbed by the Contractor's operation the Contractor shall restore, replace or rebuild all such surfaces to a condition at least equal to its condition at time of removal. Blading and maintaining of streets and roadways are covered hereinbefore in these provisions. If the alignment of the water main and its appurtenances, as shovm on the plans, is alongside or parallel to a paved roadway, but the proximity of such alignnlent to the paving does not warrant any damage or removal of such paving, the Contractor shall replace or repair the paving which he has removed or damaged at no additional compensation. -24- SC- vI 20. RESTORATION OF SOD, TREES, DRIVEWAYS, CURBS AND SIDEWALK Any and all curb and gutter or sidewalk disturbed by the Con- tractor during construction shall be replaced with new curb and gutter or sidewalk in conformance with the municipality's standards and with no additional compensation. The replace- ment shall include the obtaining of line and grade on exist- ing curb and gutter or sidewalk and setting of line and grade at tline of replacement. Any trees tvhich \.'lill lie vIithin the limits of the excavation shall be removed by the Contractor only with the express written permission of the Engineer. There shall be no additional com- pensation for the removal of such trees, but the Contractor will not be required to replace any tree so removedo Any concrete, blacktop, or crushed rock or other tJ~e of drive- way disturbed by the Contractor during construction shall be re- placed or rebuilt to a condition at least equal to its condition at time of removal. There will be no additional compensation allowed for this item. Any sod which is disturbed during the installation of water lines or appurtenances shall be replaced, including the necessary black dirt. The Contractor will be reimbursed for sodding up to a max:i.mum of a strip ten (10) feet in Nidth, measured five (5) feet on each side of the water pipe or service as installed 0 Any sod requiring replacement outside the ten (10) foot maxL~um shall be replaced by the Contractor at no additional compensation. Black dirt shall be replaced to a thickness equal to that removed tip to a maximum of one (1) foot. No sod shall be laid on less than four (4) inches of blacl-c dirt 0 Black dirt shall be light friable loam containing a liberal amount of hlliuus and shall be free from heavy clay, coarse sand, stones, plants, roots, sticks, and other foreign materials. Sod shall be rolled within 24 hours after its placement with a roller that leaves the sod smooth and the joints properly closedo The new sod shall be trimmed to neatly match old sod, curbs, and vialks.
