To the extent possible such requests shall be made before commencement of related construction at the Site. 1. Contractor shall submit sufficient information as provided below to allow Engineer to determine if the item of material or equipment proposed is functionally equivalent to that named and an acceptable substitute therefor. Engineer will not accept requests for review of proposed substitute items of material or equipment from anyone other than Contractor. 2. The requirements for review by Engineer will be as set forth in Paragraph 7.05.B, as supplemented by the Specifications, and as Engineer may decide is appropriate under the circumstances. 3. Contractor shall make written application to Engineer for review of a proposed substitute item of material or equipment that Contractor seeks to furnish or use. The application: a. shall certify that the proposed substitute item will: 1) perform adequately the functions and achieve the results called for by the general design, 2) be similar in substance to that specified,and 3) be suited to the same use as that specified. b. will state: 1) the extent, if any, to which the use of the proposed substitute item will necessitate a change in Contract Times, 2) whether use of the proposed substitute item in the Work will require a change in any of the Contract Documents (or in the provisions of any other direct contract with Owner for other work on the Project)to adapt thedesign to the proposed substitute item,and 3) whether incorporation or use of the proposed substitute item in connection with the Work is subject to payment of any license fee or royalty. c. will identify: 1) all variations of the proposed substitute item from that specified,and (F)28 of 65 2) available engineering,sales, maintenance, repair,and replacement services. d. shall contain an itemized estimate of all costs or credits that will result directly or indirectly from use of such substitute item, including but not limited to changes in Contract Price, shared savings, costs of redesign, and claims of other contractors affected by any resulting change. B. Engineer's Evaluation and Determination: Engineer will be allowed a reasonable time to evaluate each substitute request, and to obtain comments and direction from Owner. Engineer may require Contractor to furnish additional data about the proposed substitute item. Engineer will be the sole judge of acceptability. No substitute will be ordered, furnished, installed, or utilized until Engineer's review is complete and Engineer determines that the proposed item is an acceptable substitute. Engineer's determination will be evidenced by a Field Order or a proposed Change Order accounting for the substitution itself and all related impacts, including changes in Contract Price or Contract Times. Engineer will advise Contractor in writing of any negative determination. C. Special Guarantee: Owner may require Contractor to furnish at Contractor's expense a special performance guarantee or other surety with respect to any substitute. D. Reimbursement of Engineer's Cost: Engineer will record Engineer's costs in evaluating a substitute proposed or submitted by Contractor.

Subsequent to the submittal of Contractor's Bid or final negotiation of the terms of the Contract, Owner may not require Contractor to retain any Subcontractor,Supplier, or other individual or entity to furnish or perform any of the Work against which Contractor has reasonable objection. D. Prior to entry into any binding subcontract or purchase order, Contractor shall submit to Owner the identity of the proposed Subcontractor or Supplier (unless Owner has already deemed such proposed Subcontractor or Supplier acceptable, during the bidding process or otherwise). Such proposed Subcontractor or Supplier shall be deemed acceptable to Owner unless Owner raises a substantive, reasonable objection within five days. (F)29 of 65 E. Owner may require the replacement of any Subcontractor, Supplier, or other individual or entity retained by Contractor to perform any part of the Work. Owner also may require Contractor to retain specific replacements; provided, however,that Owner may not require a replacement to which Contractor has a reasonable objection. If Contractor has submitted the identity of certain Subcontractors, Suppliers, or other individuals or entities for acceptance by Owner, and Owner has accepted it (either in writing or by failing to make written objection thereto),then Owner may subsequently revoke the acceptance of any such Subcontractor, Supplier, or other individual or entity so identified solely on the basisof substantive, reasonable objection after due investigation. Contractor shall submit an acceptable replacement for the rejected Subcontractor, Supplier, or other individual or entity. F. If Owner requires the replacement of any Subcontractor, Supplier, or other individual or entity retained by Contractor to perform any part of the Work, then Contractor shall be entitled to an adjustment in Contract Price or Contract Times, or both, with respect to the replacement; and Contractor shall initiate a Change Proposal for such adjustment within 30 days of Owner's requirement of replacement.

A Change Order also may be used to establish amendments and supplements of the Contract Documents that do not affect the Contract Price or Contract Times. b. Owner and Contractor may amend those terms and conditions of the Contract Documents that do not involve (1) the performance or acceptability of the Work, (2) the design (as set forth in the Drawings, Specifications, or otherwise), or(3) other engineering or technical matters, without the recommendation of the Engineer. Such an amendment shall be set forth in a Change Order. 2. Work Change Directives: A Work Change Directive will not change the Contract Price or the Contract Times but is evidence that the parties expect that the modification ordered or documented by a Work Change Directive will be incorporated in a subsequently issued Change Order,following negotiations by the parties as to the Work Change Directive's effect, if any, on the Contract Price and Contract Times; or, if negotiations are unsuccessful, by a determination under the terms of the Contract Documents governing adjustments, expressly including Paragraph 11.04 regarding change of Contract Price. Contractor must submit any Change Proposal seeking an (F)43 of 65 adjustment of the Contract Price or the Contract Times, or both, no later than 30 days after the completion of the Work set out in the Work Change Directive.

Engineer will advise Owner regarding the Change Proposal, and consider any comments or response from Owner regarding the Change Proposal. 2. Engineer's Action: Engineer will review each Change Proposal and,within 30 days after receipt of the Contractor's supporting data, either deny the Change Proposal in whole, approve it in whole, or deny it in part and approve it in part. Such actions shall be in writing,with a copy provided to Owner and Contractor. If Engineer does not take action on the Change Proposal within 30 days,then either Owner or Contractor may atany time thereafter submit a letter to the other party indicating that as a result of Engineer's inaction the Change Proposal is deemed denied, thereby commencing the time for appeal of the denial under Article 12. 3.

Contractor shall be responsible for arranging, obtaining, and paying for all inspections and tests required: 1. by the Contract Documents, unless the Contract Documents expressly allocate responsibility for a specific inspection or test to Owner; 2. to attain Owner's and Engineer's acceptance of materials or equipment to be incorporated in the Work; 3. by manufacturers of equipment furnished under the Contract Documents; 4. for testing, adjusting, and balancing of mechanical, electrical, and other equipment to be incorporated into the Work; and 5. for acceptance of materials, mix designs, or equipment submitted for approval prior to Contractor's purchase thereof for incorporation in the Work. Such inspections and tests shall be performed by independent inspectors, testing laboratories,or other qualified individuals or entities acceptable to Owner and Engineer. E. If the Contract Documents require the Work (or part thereof) to be approved by Owner, Engineer, or another designated individual or entity, then Contractor shall assume full responsibility for arranging and obtaining such approvals. F. If any Work(or the work of others)that is to be inspected,tested,or approved is covered by Contractor without written concurrence of Engineer, Contractor shall, if requested by Engineer, uncover such Work for observation. Such uncovering shall be at Contractor's expense unless Contractor had given Engineer timely notice of Contractor's intention to (F)52 of 65 cover the same and Engineer had not acted with reasonable promptness in response to such notice. 14.03 Defective Work A. Contractor's Obligation: It is Contractor's obligation to assure that the Work is not defective. B. Engineer's Authority: Engineer has the authority to determine whether Work is defective, and to reject defective Work. C. Notice of Defects:Prompt notice of all defective Work of which Owner or Engineer has actual knowledge will be given to Contractor. D. Correction, or Removal and Replacement: Promptly after receipt of written notice of defective Work, Contractor shall correct all such defective Work,whether or not fabricated, installed, or completed, or, if Engineer has rejected the defective Work, remove it from the Project and replace it with Work that is not defective. E. Preservation of Warranties:When correcting defective Work, Contractor shall take noaction that would void or otherwise impair Owner's special warranty and guarantee, if any, on said Work. F. Costs and Damages: In addition to its correction, removal,and replacement obligations with respect to defective Work, Contractor shall pay all claims, costs, losses, and damages arising out of or relating to defective Work, including but not limited to the cost of the inspection, testing, correction, removal, replacement, or reconstruction of such defective Work, fines levied against Owner by governmental authorities because the Work is defective, and the costs of repair or replacement of work of others resulting from defective Work. Prior to final payment, if Owner and Contractor are unable to agree as to themeasure of such claims, costs, losses, and damages resulting from defective Work, then Owner may impose a reasonable set-off against payments due under Article 15. 14.04 Acceptance of Defective Work A. If, instead of requiring correction or removal and replacement of defective Work, Owner prefers to accept it, Owner may do so (subject, if such acceptance occurs prior to final payment, to Engineer's confirmation that such acceptance is in general accord with the design intent and applicable engineering principles, and will not endanger public safety). Contractor shall pay all claims,costs, losses, and damages attributable to Owner's evaluation of and determination to accept such defective Work(such costs to be approved by Engineer as to reasonableness), and for the diminished value of the Work to the extent not otherwise paid by Contractor. If any such acceptance occurs prior to final payment, the necessary revisions in the Contract Documents with respect to the Work shall be incorporated in a Change Order. If the parties are unable to agree as to the decrease in the Contract Price, reflecting the diminished value of Work so accepted, then Owner may impose a reasonable set-off against payments due under Article 15. If the acceptance of defective Work occurs after final payment, Contractor shall pay an appropriate amount to Owner. 14.05 Uncovering Work A. Engineer has the authority to require additional inspection or testing of the Work, whether or not the Work is fabricated, installed, or completed. (F)53 of 65 B. If any Work is covered contrary to the written request of Engineer, then Contractor shall, if requested by Engineer, uncover such Work for Engineer's observation, and then replace the covering,all at Contractor's expense. C. If Engineer considers it necessary or advisable that covered Work be observed by Engineer or inspected or tested by others, then Contractor, at Engineer's request, shall uncover, expose,or otherwise make available for observation, inspection, or testing as Engineer may require,that portion of the Work in question, and provide all necessary labor, material,and equipment. 1. If it is found that the uncovered Work is defective, Contractor shall be responsible for all claims, costs, losses, and damages arising out of or relating to such uncovering, exposure, observation, inspection, and testing, and of satisfactory replacement or reconstruction(including but not limited to all costs of repair or replacement of work of others); and pending Contractor's full discharge of this responsibility the Ownershall be entitled to impose a reasonable set-off against payments due under Article 15. 2. If the uncovered Work is not found to be defective, Contractor shall be allowed an increase in the Contract Price or an extension of the Contract Times, or both, directly attributable to such uncovering, exposure, observation, inspection, testing, replacement, and reconstruction. If the parties are unable to agree as to the amount or extent thereof,then Contractor may submit a Change Proposal within 30 days of the determination that the Work is not defective. 14.06 Owner May Stop the Work A. If the Work is defective, or Contractor fails to supply sufficient skilled workers or suitable materials or equipment,or fails to perform the Work in such a way that the completed Work will conform to the Contract Documents,then Owner may order Contractor to stop the Work, or any portion thereof, until the cause for such order has been eliminated; however, this right of Owner to stop the Work shall not give rise to any duty on the part of Owner to exercise this right for the benefit of Contractor, any Subcontractor, any Supplier, any other individual or entity,or any surety for,or employee or agent of any of them. 14.07 Owner May Correct Defective Work A. If Contractor fails within a reasonable time after written notice from Engineer to correct defective Work, or to remove and replace rejected Work as required by Engineer, or if Contractor fails to perform the Work in accordance with the Contract Documents, or if Contractor fails to comply with any other provision of the Contract Documents,then Owner may,after seven days written notice to Contractor, correct or remedy any such deficiency. B. In exercising the rights and remedies under this Paragraph 14.07, Owner shall proceed expeditiously. In connection with such corrective or remedial action, Owner may exclude Contractor from all or part of the Site,take possession of all or part of the Work and suspend Contractor's services related thereto, and incorporate in the Work all materialsand equipment stored at the Site or for which Owner has paid Contractor but which are stored elsewhere. Contractor shall allow Owner, Owner's representatives, agents and employees, Owner's other contractors, and Engineer and Engineer's consultants access to the Site to enable Owner to exercise the rights and remedies under this paragraph. C. All claims,costs, losses,and damages incurred or sustained by Owner in exercising therights and remedies under this Paragraph 14.07 will be charged against Contractor as set- offs against payments due under Article 15. Such claims, costs, losses and damages will (F)54 of 65 { include but not be limited to all costs of repair, or replacement of work of others destroyed or damaged by correction, removal,or replacement of Contractor's defective Work. D. Contractor shall not be allowed an extension of the Contract Times because of any delay in the performance of the Work attributable to the exercise by Owner of Owner's rights and remedies under this Paragraph 14.07. ARTICLE 15—PAYMENTS TO CONTRACTOR;SET-OFFS;COMPLETION;CORRECTION PERIOD 15.01 Progress Payments A. Basis for Progress Payments:The Schedule of Values established as provided in Article 2 will serve as the basis for progress payments and will be incorporated into a form of Application for Payment acceptable to Engineer. Progress payments on account of Unit Price Work will be based on the number of units completed during the pay period, as determined under the provisions of Paragraph 13.03. Progress payments for cost-based Work will be based on Cost of the Work completed by Contractor during the pay period. B. Applications for Payments: 1. At least 20 days before the date established in the Agreement for each progress payment (but not more often than once a month), Contractor shall submit to Engineer for review an Application for Payment filled out and signed by Contractor covering the Work completed as of the date of the Application and accompanied by such supporting documentation as is required by the Contract Documents. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the Site or at another location agreed to in writing,theApplication for Payment shall also be accompanied by a bill of sale, invoice, or other documentation warranting that Owner has received the materials and equipment free and clear of all Liens, and evidence that the materials and equipment are covered by appropriate property insurance, a warehouse bond, or other arrangements to protect Owner's interest therein,all of which must be satisfactory to Owner. 2. Beginning with the second Application for Payment, each Application shall include an affidavit of Contractor stating that all previous progress payments received on account of the Work have been applied on account to discharge Contractor's legitimate obligations associated with prior Applications for Payment. 3. The amount of retainage with respect to progress payments will be as stipulated in the Agreement. C. Review of Applications: 1. Engineer will, within 10 days after receipt of each Application for Payment, including each resubmittal, either indicate in writing a recommendation of payment and present the Application to Owner, or return the Application to Contractor indicating in writing Engineer's reasons for refusing to recommend payment. In the latter case, Contractor may make the necessary corrections and resubmit the Application. 2. Engineer's recommendation of any payment requested in an Application for Payment will constitute a representation by Engineer to Owner,based on Engineer's observations of the executed Work as an experienced and qualified design professional, and on Engineer's review of the Application for Payment and the accompanying data and schedules,that to the best of Engineer's knowledge, information and belief: (F)55of65 a. the Work has progressed to the point indicated; b. the quality of the Work is generally in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, the results of any subsequent tests called for in the Contract Documents,a final determination of quantities and classifications for Unit Price Work under Paragraph 13.03, and any other qualifications stated in the recommendation); and c. the conditions precedent to Contractor's being entitled to such payment appear to have been fulfilled in so far as it is Engineer's responsibility to observe the Work. 3. By recommending any such payment Engineer will not thereby be deemed to have represented that: a. inspections made to check the quality or the quantity of the Work as it has been performed have been exhaustive, extended to every aspect of the Work in progress, or involved detailed inspections of the Work beyond the responsibilities specifically assigned to Engineer in the Contract;or b. there may not be other matters or issues between the parties that might entitle Contractor to be paid additionally by Owner or entitle Owner to withhold payment to Contractor. 4. Neither Engineer's review of Contractor's Work for the purposes of recommending payments nor Engineer's recommendation of any payment,including final payment,will impose responsibility on Engineer: a. to supervise, direct, or control the Work, or b. for the means, methods,techniques, sequences,or procedures of construction,or the safety precautions and programs incident thereto,or c. for Contractor's failure to comply with Laws and Regulations applicable to Contractor's performance of the Work,or d. to make any examination to ascertain how or for what purposes Contractor has used the money paid on account of the Contract Price, or e. to determine that title to any of the Work, materials,or equipment has passed to Owner free and clear of any Liens. 5. Engineer may refuse to recommend the whole or any part of any payment if, in Engineer's opinion, it would be incorrect to make the representations to Owner stated in Paragraph 15.01.C.2. 6. Engineer will recommend reductions in payment (set-offs) necessary in Engineer's opinion to protect Owner from loss because: a. the Work is defective, requiring correction or replacement; b. the Contract Price has been reduced by Change Orders; c. Owner has been required to correct defective Work in accordance with Paragraph 14.07, or has accepted defective Work pursuant to Paragraph 14.04; d. Owner has been required to remove or remediate a Hazardous Environmental Condition for which Contractor is responsible; or (F)56 of 65 e. Engineer has actual knowledge of the occurrence of any of the events that would constitute a default by Contractor and therefore justify termination for cause under the Contract Documents. D. Payment Becomes Due: 1. Ten days after presentation of the Application for Payment to Owner with Engineer's recommendation, the amount recommended (subject to any Owner set-offs) will become due,and when due will be paid by Owner to Contractor. E. Reductions in Payment by Owner: 1. In addition to any reductions in payment (set-offs) recommended by Engineer, Owner is entitled to impose a set-off against payment based on any of the following: a. claims have been made against Owner on account of Contractor's conduct in the performance or furnishing of the Work, or Owner has incurred costs, losses, or damages on account of Contractor's conduct in the performance or furnishing of the Work, including but not limited to claims, costs, losses, or damages from workplace injuries, adjacent property damage, non-compliance with Laws and Regulations,and patent infringement; b. Contractor has failed to take reasonable and customary measures to avoid damage, delay,disruption,and interference with other work at or adjacent to the Site; c. Contractor has failed to provide and maintain required bonds or insurance; d. Owner has been required to remove or remediate a Hazardous Environmental Condition for which Contractor is responsible; e. Owner has incurred extra charges or engineering costs related to submittal reviews,evaluations of proposed substitutes,tests and inspections,or return visits to manufacturing or assembly facilities; f. the Work is defective, requiring correction or replacement; g. Owner has been required to correct defective Work in accordance with Paragraph 14.07,or has accepted defective Work pursuant to Paragraph 14.04; h. the Contract Price has been reduced by Change Orders; i. an event that would constitute a default by Contractor and therefore justify a termination for cause has occurred; j. liquidated damages have accrued as a result of Contractor's failure to achieve Milestones,Substantial Completion,or final completion of the Work; k. Liens have been filed in connection with the Work, except where Contractor has delivered a specific bond satisfactory to Owner to secure the satisfaction and discharge of such Liens; I. there are other items entitling Owner to a set off against the amount recommended. 2. If Owner imposes any set-off against payment, whether based on its own knowledge or on the written recommendations of Engineer,Owner will give Contractorimmediate written notice (with a copy to Engineer) stating the reasons for such action and the specific amount of the reduction, and promptly pay Contractor any amount (F)57 of 65 remaining after deduction of the amount so withheld. Owner shall promptly pay Contractor the amount so withheld,or any adjustment thereto agreed to by Owner and Contractor, if Contractor remedies the reasons for such action. The reduction imposed shall be binding on Contractor unless it duly submits a Change Proposal contesting the reduction. 3. Upon a subsequent determination that Owner's refusal of payment was not justified, the amount wrongfully withheld shall be treated as an amount due as determined by Paragraph 15.01.C.1 and subject to interest as provided in the Agreement. 15.02 Contractor's Warranty of Title A. Contractor warrants and guarantees that title to all Work, materials, and equipment furnished under the Contract will pass to Owner free and clear of(1)all Liens and other title defects, and (2) all patent, licensing, copyright, or royalty obligations, no later than seven days after the time of payment by Owner. 15.03 Substantial Completion A. When Contractor considers the entire Work ready for its intended use Contractor shall notify Owner and Engineer in writing that the entire Work is substantially complete and request that Engineer issue a certificate of Substantial Completion.Contractor shall at the same time submit to Owner and Engineer an initial draft of punch list items to be completed or corrected before final payment. B. Promptly after Contractor's notification, Owner, Contractor, and Engineer shall make an inspection of the Work to determine the status of completion. If Engineer does not consider the Work substantially complete,Engineer will notify Contractor in writing giving the reasons therefor. C. If Engineer considers the Work substantially complete, Engineer will deliver to Owner a preliminary certificate of Substantial Completion which shall fix the date of Substantial Completion. Engineer shall attach to the certificate a punch list of items to be completed or corrected before final payment.Owner shall have seven days after receipt of the preliminary certificate during which to make written objection to Engineer as to any provisions of the certificate or attached punch list. If, after considering the objections to theprovisions of the preliminary certificate, Engineer concludes that the Work is not substantially complete, Engineer will,within 14 days after submission of the preliminary certificate to Owner, notify Contractor in writing that the Work is not substantially complete, stating the reasons therefor. If Owner does not object to the provisions of the certificate, or if despite consideration of Owner's objections Engineer concludes that the Work is substantially complete, then Engineer will, within said 14 days, execute and deliver to Owner and Contractor a final certificate of Substantial Completion (with a revised punch list of items to be completed or corrected) reflecting such changes from the preliminary certificate as Engineer believes justified after consideration of any objections from Owner. D. At the time of receipt of the preliminary certificate of Substantial Completion, Owner and Contractor will confer regarding Owner's use or occupancy of the Work following Substantial Completion, review the builder's risk insurance policy with respect to the end ofthe builder's risk coverage, and confirm the transition to coverage of the Work under a permanent property insurance policy held by Owner. Unless Owner and Contractor agree otherwise in writing, Owner shall bear responsibility for security, operation, protection of the Work, property insurance, maintenance, heat, and utilities upon Owner's use or occupancy of the Work. (F)58 of 65 E. After Substantial Completion the Contractor shall promptly begin work on the punch list of items to be completed or corrected prior to final payment. In appropriate cases Contractor may submit monthly Applications for Payment for completed punch list items,following the progress payment procedures set forth above. F. Owner shall have the right to exclude Contractor from the Site after the date of Substantial Completion subject to allowing Contractor reasonable access to remove its property and complete or correct items on the punch list. 15.04 Partial Use or Occupancy A. Prior to Substantial Completion of all the Work, Owner may use or occupy any substantially completed part of the Work which has specifically been identified in the Contract Documents, or which Owner, Engineer, and Contractor agree constitutes a separately functioning and usable part of the Work that can be used by Owner for its intendedpurpose without significant interference with Contractor's performance of the remainderof the Work,subject to the following conditions: 1. At any time Owner may request in writing that Contractor permit Owner to use or occupy any such part of the Work that Owner believes to be substantially complete. If and when Contractor agrees that such part of the Work is substantially complete, Contractor, Owner, and Engineer will follow the procedures of Paragraph 15.03.A through E for that part of the Work. 2. At any time Contractor may notify Owner and Engineer in writing that Contractor considers any such part of the Work substantially complete and request Engineer to issue a certificate of Substantial Completion for that part of the Work. 3. Within a reasonable time after either such request, Owner, Contractor, and Engineer shall make an inspection of that part of the Work to determine its status of completion. If Engineer does not consider that part of the Work to be substantially complete, Engineer will notify Owner and Contractor in writing giving the reasons therefor. If Engineer considers that part of the Work to be substantially complete,the provisions of Paragraph 15.03 will apply with respect to certification of Substantial Completion of that part of the Work and the division of responsibility in respectthereof and access thereto. 4. No use or occupancy or separate operation of part of the Work may occur prior to compliance with the requirements of Paragraph 6.05 regarding builder's risk or other property insurance. 15.05 Final Inspection A. Upon written notice from Contractor that the entire Work or an agreed portion thereof is complete,Engineer will promptly make a final inspection with Owner and Contractor and will notify Contractor in writing of all particulars in which this inspection reveals that the Work, or agreed portion thereof,is incomplete or defective.Contractor shall immediately take such measures as are necessary to complete such Work or remedy such deficiencies. 15.06 Final Payment A. Application for Payment: 1. After Contractor has, in the opinion of Engineer,satisfactorily completed allcorrections identified during the final inspection and has delivered, in accordance with the Contract Documents, all maintenance and operating instructions,schedules,guarantees, bonds, certificates or other evidence of insurance,certificates of (F)59of65 inspection, annotated record documents (as provided in Paragraph 7.11), and other documents,Contractor may make application for final payment. 2. The final Application for Payment shall be accompanied(except as previously delivered) by: a. all documentation called for in the Contract Documents; b. consent of the surety, if any,to final payment; c. satisfactory evidence that all title issues have been resolved such that title to all Work, materials, and equipment has passed to Owner free and clear of any Liens or other title defects,or will so pass upon final payment. d. a list of all disputes that Contractor believes are unsettled; and e. complete and legally effective releases or waivers(satisfactory to Owner)of all Lien rights arising out of the Work,and of Liens filed in connection with the Work. 3. In lieu of the releases or waivers of Liens specified in Paragraph 15.06.A.2 and as approved by Owner, Contractor may furnish receipts or releases in full and an affidavit of Contractor that: (a) the releases and receipts include all labor, services, material, and equipment for which a Lien could be filed; and (b) all payrolls, material and equipment bills, and other indebtedness connected with the Work for which Owner might in any way be responsible, or which might in any way result in liens or other burdens on Owner's property, have been paid or otherwise satisfied. If any Subcontractor or Supplier fails to furnish such a release or receipt in full,Contractor may furnish a bond or other collateral satisfactory to Owner to indemnify Owner against any Lien, or Owner at its option may issue joint checks payable to Contractor and specified Subcontractors and Suppliers. B. Engineer's Review of Application and Acceptance: 1. If, on the basis of Engineer's observation of the Work during construction and final inspection, and Engineer's review of the final Application for Payment and accompanying documentation as required by the Contract Documents, Engineer is satisfied that the Work has been completed and Contractor's other obligations under the Contract have been fulfilled, Engineer will, within ten days after receipt of the final Application for Payment, indicate in writing Engineer's recommendation of final payment and present the Application for Payment to Owner for payment. Such recommendation shall account for any set-offs against payment that are necessary in Engineer's opinion to protect Owner from loss for the reasons stated above with respect to progress payments.At the same time Engineer will also give written notice to Owner and Contractor that the Work is acceptable, subject to the provisions of Paragraph 15.07. Otherwise, Engineer will return the Application for Payment to Contractor, indicating in writing the reasons for refusing to recommend final payment, in which case Contractor shall make the necessary corrections and resubmit the Application for Payment. C. Completion of Work:The Work is complete(subject to surviving obligations)when it is ready for final payment as established by the Engineer's written recommendation of final payment. D. Payment Becomes Due: Thirty days after the presentation to Owner of the final Application for Payment and accompanying documentation,the amount recommended by Engineer(less any further sum Owner is entitled to set off against Engineer's recommendation, (F)60 of 65 including but not limited to set-offs for liquidated damages and set-offs allowed under the provisions above with respect to progress payments) will become due and shall be paid by Owner to Contractor. 15.07 Waiver of Claims A. The making of final payment will not constitute a waiver by Owner of claims or rights against Contractor. Owner expressly reserves claims and rights arising from unsettled Liens,from defective Work appearing after final inspection pursuant to Paragraph 15.05, from Contractor's failure to comply with the Contract Documents or the terms of any special guarantees specified therein, from outstanding Claims by Owner, or from Contractor's continuing obligations under the Contract Documents. B. The acceptance of final payment by Contractor will constitute a waiver by Contractor of all claims and rights against Owner other than those pending matters that have been duly submitted or appealed under the provisions of Article 17. 15.08 Correction Period A. If within one year after the date of Substantial Completion (or such longer period of time as may be prescribed by the terms of any applicable special guarantee required by the Contract Documents, or by any specific provision of the Contract Documents), any Work is found to be defective, or if the repair of any damages to the Site, adjacent areas that Contractor has arranged to use through construction easements or otherwise, and other adjacent areas used by Contractor as permitted by Laws and Regulations, is found to be defective, then Contractor shall promptly, without cost to Owner and in accordance with Owner's written instructions: 1. correct the defective repairs to the Site or such other adjacent areas; 2. correct such defective Work; 3. if the defective Work has been rejected by Owner, remove it from the Project and replace it with Work that is not defective, and 4. satisfactorily correct or repair or remove and replace any damage to other Work,to the work of others,or to other land or areas resulting therefrom. B. If Contractor does not promptly comply with the terms of Owner's written instructions, or in an emergency where delay would cause serious risk of loss or damage, Owner may have the defective Work corrected or repaired or may have the rejected Work removed and replaced.Contractor shall pay all claims,costs,losses,and damages(including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or repair or such removal and replacement (including but not limited to all costs of repair or replacement of work of others). C. In special circumstances where a particular item of equipment is placed in continuous service before Substantial Completion of all the Work,the correction period for that item may start to run from an earlier date if so provided in the Specifications. D. Where defective Work(and damage to other Work resulting therefrom) has been corrected or removed and replaced under this paragraph,the correction period hereunder withrespect to such Work will be extended for an additional period of one year after such correction or removal and replacement has been satisfactorily completed. (F)61of65 E. Contractor's obligations under this paragraph are in addition to all other obligations and warranties. The provisions of this paragraph shall not be construed as a substitute for, or a waiver of,the provisions of any applicable statute of limitation or repose. ARTICLE 16—SUSPENSION OF WORK AND TERMINATION 16.01 Owner May Suspend Work A. At any time and without cause, Owner may suspend the Work or any portion thereof for a period of not more than 90 consecutive days by written notice to Contractor and Engineer. Such notice will fix the date on which Work will be resumed. Contractor shall resume the Work on the date so fixed. Contractor shall be entitled to an adjustment in the Contract Price or an extension of the Contract Times, or both, directly attributable to any such suspension. Any Change Proposal seeking such adjustments shall be submitted no laterthan 30 days after the date fixed for resumption of Work. 16.02 Owner May Terminate for Cause A. The occurrence of any one or more of the following events will constitute a default by Contractor and justify termination for cause: 1. Contractor's persistent failure to perform the Work in accordance with the Contract Documents (including, but not limited to, failure to supply sufficient skilled workers or suitable materials or equipment or failure to adhere to the Progress Schedule); 2. Failure of Contractor to perform or otherwise to comply with a material term of the Contract Documents; 3. Contractor's disregard of Laws or Regulations of any public body having jurisdiction;or 4. Contractor's repeated disregard of the authority of Owner or Engineer. B. If one or more of the events identified in Paragraph 16.02.A occurs, then after giving Contractor(and any surety)ten days written notice that Owner is considering a declaration that Contractor is in default and termination of the contract, Owner may proceed to: 1. declare Contractor to be in default,and give Contractor(and any surety) notice that the Contract is terminated;and 2. enforce the rights available to Owner under any applicable performance bond. C. Subject to the terms and operation of any applicable performance bond, if Owner has terminated the Contract for cause, Owner may exclude Contractor from the Site, take possession of the Work, incorporate in the Work all materials and equipment stored at the Site or for which Owner has paid Contractor but which are stored elsewhere, and complete the Work as Owner may deem expedient. D. Owner may not proceed with termination of the Contract under Paragraph 16.02.E if Contractor within seven days of receipt of notice of intent to terminate begins to correct its failure to perform and proceeds diligently to cure such failure. E. If Owner proceeds as provided in Paragraph 16.02.B, Contractor shall not be entitled to receive any further payment until the Work is completed. If the unpaid balance of the Contract Price exceeds the cost to complete the Work, including all related claims, costs, losses,and damages(including but not limited to all fees and charges of engineers,architects, attorneys, and other professionals) sustained by Owner, such excess will be paid to Contractor. If the cost to complete the Work including such related claims, costs, losses, (F)62 of 65 and damages exceeds such unpaid balance, Contractor shall pay the difference to Owner. Such claims, costs, losses, and damages incurred by Owner will be reviewed by Engineer as to their reasonableness and,when so approved by Engineer,incorporated in a Change Order. When exercising any rights or remedies under this paragraph, Owner shall not be required to obtain the lowest price for the Work performed. F. Where Contractor's services have been so terminated by Owner, the termination will not affect any rights or remedies of Owner against Contractor then existing or which may thereafter accrue,or any rights or remedies of Owner against Contractor or any surety under any payment bond or performance bond.Any retention or payment of money due Contractor by Owner will not release Contractor from liability. G. If and to the extent that Contractor has provided a performance bond under the provisions of Paragraph 6.01.A,the provisions of that bond shall govern over any inconsistent provisions of Paragraphs 16.02.B and 16.02.D. 16.03 Owner May Terminate For Convenience A. Upon seven days written notice to Contractor and Engineer,Owner may,without cause and without prejudice to any other right or remedy of Owner, terminate the Contract. In such case, Contractor shall be paid for(without duplication of any items): 1. completed and acceptable Work executed in accordance with the Contract Documents prior to the effective date of termination, including fair and reasonable sums for overhead and profit on such Work; 2. expenses sustained prior to the effective date of termination in performing services and furnishing labor, materials, or equipment as required by the Contract Documents in connection with uncompleted Work, plus fair and reasonable sums for overhead and profit on such expenses;and 3. other reasonable expenses directly attributable to termination,including costs incurred to prepare a termination for convenience cost proposal. B. Contractor shall not be paid on account of loss of anticipated overhead, profits,or revenue, or other economic loss arising out of or resulting from such termination. 16.04 Contractor May Stop Work or Terminate A. If, through no act or fault of Contractor, (1) the Work is suspended for more than 90 consecutive days by Owner or under an order of court or other public authority, or (2) Engineer fails to act on any Application for Payment within 30 days after it is submitted, or (3) Owner fails for 30 days to pay Contractor any sum finally determined to be due, then Contractor may,upon seven days written notice to Owner and Engineer,and provided Owner or Engineer do not remedy such suspension or failure within that time, terminate the contract and recover from Owner payment on the same terms as provided in Paragraph 16.03. B. In lieu of terminating the Contract and without prejudice to any other right or remedy, if Engineer has failed to act on an Application for Payment within 30 days after it is submitted, or Owner has failed for 30 days to pay Contractor any sum finally determined to be due, Contractor may,seven days after written notice to Owner and Engineer,stop the Work until payment is made of all such amounts due Contractor, including interest thereon.The provisions of this paragraph are not intended to preclude Contractor from submitting a Change Proposal for an adjustment in Contract Price or Contract Times or otherwise for (F)63of65 expenses or damage directly attributable to Contractor's stopping the Work as permitted by this paragraph. ARTICLE 17—FINAL RESOLUTION OF DISPUTES 17.01 Methods and Procedures A. Disputes Subject to Final Resolution: The following disputed matters are subject to final resolution under the provisions of this Article: 1. A timely appeal of an approval in part and denial in part of a Claim,or of a denial infull; and 2. Disputes between Owner and Contractor concerning the Work or obligations under the Contract Documents,and arising after final payment has been made. B. Final Resolution of Disputes: For any dispute subject to resolution under this Article, Owner or Contractor may: 1. elect in writing to invoke the dispute resolution process provided for in the Supplementary Conditions;or 2. agree with the other party to submit the dispute to another dispute resolution process; or 3. if no dispute resolution process is provided for in the Supplementary Conditions or mutually agreed to, give written notice to the other party of the intent to submit the dispute to a court of competent jurisdiction. ARTICLE 18—MISCELLANEOUS 18.01 Giving Notice A. Whenever any provision of the Contract Documents requires the giving of written notice, it will be deemed to have been validly given if: 1. delivered in person, by a commercial courier service or otherwise, to the individual or to a member of the firm or to an officer of the corporation for which it is intended;or 2. delivered at or sent by registered or certified mail, postage prepaid,to the last business address known to the sender of the notice. 18.02 Computation of Times A. When any period of time is referred to in the Contract by days, it will be computed to exclude the first and include the last day of such period.

E. 1.5 lbs of fiber mesh per cubic yard of concrete, where noted for use on plans,shall be added to the mixer before placement. Fibermesh is required in all sidewalks. F. Average Strength Reduction After sufficient test data become available from the job, methods of "Recommended Practice for Evaluation of Compression Test Results of Concrete (ACI 214-65)" may be used to reduce the amount by which the average strength must exceed f'c 1. Probable frequency of strength tests more than 500 psi below fc will not exceed 1 in 100; 2. Probable frequency of an average of three consecutive strength tests below fc will not exceed 1 in 100, and; 3. Concrete Classification Requirements Table are met. G. Evaluation and Acceptance of Concrete H. Frequency of Testing. Samples for strength tests of each class of concrete placed each day shall be taken not less than once a day, nor less than once for each 150 cubic yard of concrete, nor less than once for each 5000 sq. ft. of surface area for slabs or walls. M8 ITEM 200 - STRUCTURAL CONCRETE On a given project, if total volume of concrete is such that frequency of testing required would provide less than five strength tests for a given class of concrete, tests shall be made from at least five randomly selected batches or from each batch if fewer than five batches are used. When total quantity of a given class of concrete is less than 50 cubic yards, strength tests may be waived by the Engineer if in his judgment adequate evidence of satisfactory strength is provided. Average strength of two cylinders from the same sample, tested at 28 days or the specified earlier age, is required for each strength test. I. Tests of Cured Specimens. Samples for strength tests shall be taken in accordance with "Method of Sampling Fresh Concrete" (ASTM C-172). Cylinders for strength tests shall be molded and laboratory-cured in accordance with"Method of Making and Curing Concrete Test Specimens in the Field" (ASTM C-31) and tested in accordance with "Method of Test for Compressive Strength of Cylindrical Concrete Specimens" (ASTM C-39). Strength level of an individual class of concrete shall be considered satisfactory if both of the following requirements are met: 1. The average of all sets of three consecutive strength tests equal or exceed required f'c. 2. No individual strength test (average of two cylinders) falls below required fc by more than 500 psi. J. Investigation of Low-Strength Test Results. If any strength test of cured cylinders falls below required fc by more than 500 psi or if test indicate deficiencies in protection and curing, steps shall be taken to assure that load-carrying capacity of the structure is not jeopardized. If the likelihood of low-strength concrete is confirmed and computations indicate that load- carrying capacity may have been significantly reduced,tests of cores drilled from the area in question may be required in accordance with "Method of Obtaining and Testing Drilled Cores and Sawed Beams of Concrete" (ASTM C-42). In such case, three cores shall be taken for each strength test more than 500 psi below required f'o. If concrete in the structure will be dry under service conditions, cores shall be air dried (temperature 60•to 80• F, relative humidity less than sixty(60%) percent)for seven (7)days before test and shall be tested dry. If concrete in the structure will be more than superficially wet under service conditions, cores shall be immersed in water for at least 48 hours and be tested wet. Concrete in an area represented by core tests shall be considered structurally adequate if the average of three cores is equal to at least eighty-five(85%) percent of f'c and if no single core is less than seventy-five (75%) percent of fc. To check testing accuracy, locations represented by erratic core strengths may be retested. If criteria above are not met, and if structural adequacy remains in doubt, the Engineer may order load tests for the questionable portion of the structure, or take other action appropriate to the circumstances.

M 19 ITEM 400- UNDERGROUND PIPING CONSTRUCTION 400.01 - DESCRIPTION This item shall govern the construction of water mains, sanitary sewers, and under drains, complete in place. This item provides for all clearing and grubbing, excavation, tunnelling, sheeting, bracing, embedment, connecting to new or old work, laying,jointing, excluding water, backfilling, tamping, and removal and replacement of street surfaces; and the furnishing of all materials, equipment, tools, labor, and incidentals for complete line construction. Point repairs to existing water or sewer lines are excluded from work under this item, except insofar as the items providing for point repairs may refer to this item. 400.02 - MATERIALS As specified elsewhere in the Technical Specifications. 400.03 - SEQUENCE OF WORK All gravity sewer lines shall be laid beginning at the downstream connection to existing facilities. When construction involves a main trunk having lateral or tributary lines, the latter shall not be started until the main trunk has been built to the point of their junction unless otherwise approved by the Engineer. All appurtenances shall be constructed as soon as the pipeline they serve is constructed to their location, rather than constructing them in advance or postponing construction. However, if construction reaches a point requiring installation of an appurtenance for which the materials are not immediately available, upon approval of the Engineer, the Contractor shall provide sufficient space for installation at a later time. The open ends of pipe shall be properly sealed and backfilled. The Contractor shall excavate the trench to finish grade fifty (50') feet to one hundred (100') feet ahead of the end of the completed pipeline. No excavation shall be performed farther than three hundred (300')feet beyond the completed pipeline, except for isolated excavations which may be required to locate existing utilities. These limitations shall not apply to tunnel installations. Each tunnel required by the plans and specifications shall be excavated, lined, and back packed for its entire length before laying pipe through the tunnel. For any tunnels constructed at the Contractor's option, the work sequence shall be as approved by the Engineer. 400.04 - PUBLIC CONVENIENCE AND SAFETY Materials stored about the work shall be so placed, and the work shall at all times be so conducted as to cause no greater obstruction to the traveling public than is considered necessary by the Engineer. Sidewalks must not be obstructed except by special permission of the Engineer. The materials excavated and the construction materials or plant used in the construction of the work shall be placed so as not to endanger the work, or prevent free access to all fire hydrants; water and gas valves; manholes for telephone, telegraph, signal, or electric conduits; sanitary or storm sewers; and fire alarm or police call boxes in the vicinity. The Contractor shall make provisions by bridges or otherwise at all cross streets, highways, sidewalks, and private driveways for the free passage of pedestrians and vehicles. Where bridging M 20 ITEM 400 - UNDERGROUND PIPING CONSTRUCTION is impractical or unnecessary in the opinion of the Engineer, the Contractor may make arrangements satisfactory to the Engineer for the diversion of traffic and shall, at his own expense, provide all material and perform all work necessary for the construction and maintenance of roadways and bridges for the diversion of traffic. At no time shall more than two (2) blocks be closed to traffic. Where practical, the Contractor shall leave at least two(2) access routes open to any residential or commercial area. If pipe line construction or construction traffic creates a need for dust control, as along dirt streets, the Contractor shall at his own expense perform all necessary sprinkling as directed by the Engineer. The Owner reserves the right to remedy any neglect on the part of the Contractor regarding public convenience and safety which may come to its attention, after twenty-four (24) hours notice in writing to the Contractor. In cases or emergency, the Owner shall have the right to remedy any neglect without notice. In either case, the cost of such work done by the Owner shall be deducted from monies due or to become due the Contractor. The Contractor shall notify the Engineer and the local street or road department forty-eight (48) hours in advance (excluding Saturdays, Sundays, and holidays) of the closing or obstruction of any street. Where the Contractor is required to construct temporary bridges or make other arrangements for crossings over ditches or streams, his responsibility for accidents shall include the roadway approaches as well as the structures of such crossings. 400.05 - BARRICADES, LIGHTS, AND WATCHMEN Where the work is being performed in or adjacent to any street, alley, or public place, the Contractor shall, at his own cost and expense, furnish and erect such barricades, fences, lights, and danger signals; shall provide such watchmen; and shall take such other precautionary measures for the protection of persons or property and of the work as are necessary. Barricades shall be recently painted in a color that will be visible at night. From sunset to sunrise the Contractor shall furnish and maintain adequate lights at each barricade. A sufficient number of barricades shall be erected to keep vehicles from being driven on or into any work under construction. The Contractor shall furnish watchmen in sufficient numbers to protect the work at all times from vandalism or related instances. The Contractor shall be held responsible for all damage to the work due to failure of barricades, signs, lights, and watchmen to protect it. Whenever evidence is found of such damage, the Engineer may order the damaged portion immediately removed and replaced by the Contractor at the Contractor's cost and expense. The Contractor's responsibility for the maintenance of barricades, signs, and lights, and for providing watchmen, shall not cease until the project has been accepted by the Owner. 400.06 - PROTECTION AND RESTORATION OF PROPERTY The Contractor shall not enter upon private property for any purpose without previously obtaining permission from the property owner. The Contractor shall notify the proper representative of any public utility, corporation, company, or individual not less than forty-eight(48) hours in advance of any work which might damage or interfere with the operation of their facilities along or adjacent to the work. M21 ITEM 400 - UNDERGROUND PIPING CONSTRUCTION The Contractor shall be responsible for the preservation of all public and private property along or adjacent to the work, including trees, shrubbery, plants, lawns, fences, culverts, bridges, pavement, driveways, sidewalks, etc.; drainage facilities; and all underground or above ground utilities. Any pavement or sidewalks which must be removed shall be replaced according to Sections 400.16 and 400.17. The Contractor shall be responsible for all direct or indirect damage to property of any character resulting from any act, omission, or negligence in execution of the work;from non-execution of the work; or from defective work or materials. When any such damage occurs, the Contractor shall restore the affected property to a condition at least equal to its condition prior to the damage, or shall fully compensate the property owner. Such restoration shall be at the Contractor's expense, except for any items specifically designated in the plans and specifications. The Owner may, upon forty-eight (48) hours written notice (or without notice when a nuisance or hazardous condition occurs), proceed to restore any property damage which the Engineer deems necessary. The cost of such restoration will be deducted from any monies due or to become due the Contractor under this contract. If the Contractor discovers that existing utilities present obstructions to construction of lines or appurtenances, he shall immediately notify the Engineer. The Engineer will determine without delay whether existing improvements should be relocated, or whether the grade and/or alignment of the line should be changed. When necessary to move services, poles, guy wires, pipelines, or other obstructions, the Contractor will make necessary arrangements with the owner-operator of utilities. The Owner will not be liable for damages on account of delays due to changes made by owner-operator of privately owned utilities which hinder progress of work. The Owner will not be liable for cost incurred in relocatingutility service poles, services, and appurtenances (unless specifically designated for payment). 400.07 - CLEARING AND GRUBBING All trees, stumps, brush, roots, logs, rubbish, and other objectionable material in the path of the storm sewer,water line or sewer line shall be removed and disposed of in a manner satisfactory to the Engineer, without any extra compensation to the Contractor. 400.08 -TEMPORARY SEWER AND DRAIN CONNECTIONS When existing sewers or drains have to be taken up or removed, the Contractor shall take care of all sewage or drainage from these facilities. For this purpose the Contractor shall provide and maintain, at his own expense, all necessary temporary connections, outlets, diversions, and pumping facilities. The Contractor shall dispose of all drainage and sewage from these facilities until the permanent connections are built and put into use, unless otherwise provided for in these specifications or as directed by the Engineer. All water or sewage shall be disposed of in a satisfactory manner so that no nuisance is created and so that the work under construction will be adequately protected. M 22 ITEM 400- UNDERGROUND PIPING CONSTRUCTION 400.09 -TRENCH EXCAVATION 1. General. The Contractor shall excavate the trench to finish grade at least fifty (50') feet ahead of pipe laying unless physical conditions make this impractical. Bell holes shall be excavated in advance of pipe laying. If a trenching machine (not a backhoe) is used to excavate the trench for a water line, with Engineers approval, selected loose, fine excavated material may be used in lieu of sand embedment around the pipe. 2. Sewers. The ground shall be excavated by the open trench method to the required depth, line, and grade as indicated on the drawings. Excavated material shall not be removed from the site of work until backfilling is completed, except by permission of the Engineer. The sides of the trench shall be vertical to a point not less than twelve(12") inches above the top of the sewer pipe. The sides of the trench shall be between six (6") and eight(8") inches outside the pipe for pipe sizes ten (10") inches or less; and between eight (8") inches and twelve (12") inches outside the pipe for sizes larger than ten (10") inches. The bottom of the trench shall be excavated a minimum of four (4") inches below required grade and refilled to grade with thoroughly compacted select material bedding. 3. Water Mains. Trench requirements for water mains shall be the same as for sewer lines. 4. Other Trench Designs. If the specifications for the type of pipe being used contain special trench requirements, those requirements shall be followed in lieu of Subsection 2 or 3 above. 5. Unstable Soils. If unstable material is encountered at the bottom of the trench, the Contractor shall undercut and stabilize the trench with suitable materials such as shell or cement stabilized sand (one (1) sack cement per ton, or Class I embedment material in accordance with Item 500 and at the direction of the Engineer. 6. Locating Intersecting Pipes. Before laying a segment of line, the Contractor shall attempt to locate all utilities which might interfere with the proposed alignment and grade. He shall locate and excavate in advance all water lines, sewer lines, service lines, and appurtenances to which the proposed line will be connected, so that the Engineer can make any necessary adjustments in alignment or grade. The owners of all utilities crossing or closely paralleling the proposed alignment shall be notified in advance of construction. 7. Dewaterinq A. Under no circumstances shall surface water be allowed to flow in the trench. When ground water exists in the trench, the Contractor shall make attempts to drain it away from the pipe laying area or pump it out of the trench. Where necessary in the opinion of the Engineer, the Contractor shall dewater the trench by the well point method. The Contractor may also use well pointing at his option in other locations. If quicksand or water sand conditions appear in the trench bottom, the Contractor shall M 23 ITEM 400- UNDERGROUND PIPING CONSTRUCTION undercut the trench and replace it with Class I embedment as follows: Angular, 1/4 to 1-1/2 inch graded stone including crushed stone, crushed shells, slag, cinders, etc. B. Trench Dewaterinq. Trench dewatering is sufficient removal of groundwater to keep an excavation reasonably dry. This means dry enough to eliminate the need for any special bedding and insure safe installation of the carrier pipe. The groundwater table shall be kept a minimum of two feet(2') below the bottom of the excavation. (1) Well Points. Where well points are used to dewater the trench the maximum allowable spacing shall be six feet (6') center to center. The minimum allowable depth of well points shall be equal to the depth of the excavation plus five feet(5'). Well points shall be set deeper if necessary to draw the groundwater down below the bottom of the excavation. Well points shall have metal well screens a minimum of two inches (2") in diameter and three feet (3') long. The well screens and riser shall be surrounded by filter sand up to the water table and the space above shall be sealed with clay. Two inch (2") diameter piezometers shall be installed at 250 foot centers to establish the extent that dewatering is necessary. At least one volume of water shall be ejected from the piezometer and then allowed to recharge prior to each groundwater measurement taken. (2) Deep Wells. Deep wells may be used as a means of trench dewatering provided the following information is submitted to the Engineer for his approval. (a) A certified well draw down curve prepared by a registered professional geotechnical engineer. Information to be submitted with the draw down curve shall include the type and classification of the soil to be dewatered, permeability of soil, and all information necessary for preparing curve. (b) Proposed well construction details including size of casing, type of pump, depth of well, filter material, screen details, and all other details necessary for well construction. (c) The rate of draw down of the groundwater table. Two inch (2") piezometers shall also be installed in the same manner as for well points to measure the groundwater table. The Engineer will use the draw down curve submitted above along with the groundwater table elevations to determine the maximum allowable spacing of the deep wells. (3) Other Methods. Other methods of trench dewatering may be used provided prior approval has been obtained from the Engineer. C. Dewatering of Tunnels. All tunnels and access pits shall be kept free of groundwater and surface water at all times. Method to be used shall be as approved by Engineer. Any cost incurred for dewatering of tunnels and access pits shall be included in the cost of installing the tunnel liner with no extra compensation. M 24 ITEM 400- UNDERGROUND PIPING CONSTRUCTION D. Settlement. Prior to performing any dewatering,the Contractor shall take all necessary precautions to insure that the dewatering operation does not cause structures near the excavation to settle. 400.10 - SHEETING AND BRACING The Contractor shall provide all sheeting and bracing necessary for the protection of the work, employees, or any existing utilities or structures. No such sheeting shall be removed from below the spring line of the pipe after the pipe has been backfilled to this level. In the event the soil conditions are such that the Contractor should desire to leave such sheeting above the spring line in place, he shall secure the permission of the Engineer to do so. The cost of any necessary sheeting or bracing, whether left in place or removed, shall be included in the unit price of the pipe being laid. 400.11 - LAYING PIPE The Engineer will establish such general reference points and construction stakes as in his judgment will enable the Contractor to proceed with the work. The Contractor will be responsible for the layout of the work from these stakes and will protect and preserve the established reference points and construction stakes and will make no changes or relocations without prior written approval. He will report to the Engineer whenever any reference point or construction stake is lost or destroyed or requires relocation because of necessary changes in grades or locations. The Contractor will replace and accurately relocate all reference points and construction stakes so lost, destroyed, or moved. All pipe lines must be laid in a straight line, unless otherwise shown on the drawings, and with the flow line of the pipe accurately placed to the grade and alignment fixed by the Engineer. A joint shall be located within two (2) pipe diameters (thirty (30") inches maximum) outside the walls of each proposed manhole or junction box, both upstream and downstream. Joints shall also be placed near other rigid connections, or near the ends of pipe casings, when recommended by the manufacturer or by the appropriate ASTM specification. No variation from true and even grade, alignment, and invert will be permitted except to avoid existing underground main service lines of utilities, and then only upon the written permission of the Engineer, signed by him personally, should he find such deviation to be desirable and not detrimental to the pipe line. All pipes shall be laid with the spigot-end or tongue end downstream entering the bell or groove to full depth. Care shall be taken in placing pipe to prevent any earth being dragged into or left in the annular space for sealing of the joints. After the trench has been carefully graded and all bell holes excavated, the trench must receive the approval of the Inspector before any pipe is placed therein. Each piece of pipe shall be examined for defects and cut to the correct lengths. The interior surface and the bell and spigot shall be thoroughly cleaned of all foreign material prior to placing same in the trench in an approved manner. The pipe, valves, fittings, etc., shall be adjusted so as to be at their proper locations and then each spigot properly fitted into position. Each length of pipe shall rest on the bottom of the trench M 25 ITEM 400 - UNDERGROUND PIPING CONSTRUCTION throughout its entire length. Joints shall be as specified in the 500 series material technical specifications as provided herein. Instructions for jointing pipes with special couplings shall be in strict conformity with the Manufacturer's printed instructions. If a defective piece of pipe furnished and placed by the Contractor should collapse,the Contractor shall furnish at his expense all labor and materials required for removing and replacing the defective pipe and restoring the street or other surface to its condition prior to the failure of the pipe. All pressure piping shall have thrust blocks installed as designated on the drawings. 400.12 - PLUGGING ENDS Before leaving the work for the night, or at any time, any openings in the pipeline shall be securely closed with a tight fitting plug. Cost of plugging pipe ends shall be included with the cost of installing the pipe. 400.13 - PROTECTIVE COATINGS All metal, bolts, and nuts shall receive a protective coating with an asphaltic compound acceptableto the Engineer before backfilling. Surface preparation shall be in accordance with the coating manufacturer's recommendations. 400.14 -TIME OF BACKFILLING Backfilling shall begin as soon as the joints have been completed and all protective coating applied.All open trenches shall be completely backfilled before the work day ends, unless otherwise directed by the Engineer. 400.15 - BACKFILLING OF TRENCH 1. Lower Portion of Trench (initial backfill). Care shall be taken to see that no dirt clods or trench sides are allowed to fall and/or rest against the pipe prior to completion of the sand encasement. a. Sewer Lines. Six (6") inches of sand bedding shall be provided in the bottom of the trench (trench having been cut six (6") inches below grade), prior to laying the pipe and making up the joints. After the pipe has been placed, the backfill around and to a point twelve inches (12") above the top of the pipe shall be made in accordance with the installation specifications for the pipe material being installed as outlined in the 500 series material technical specifications provided herein. b. Water Lines. Six (6") inches of sand bedding shall be provided in the bottom of the trench (trench having been cut six (6") inches below grade), prior to laying the pipe and making up the joints. After the pipe has been placed, the backfill around and to a point six inches (6") above the top of the pipe shall be made in accordance with the installation specifications for the pipe material being installed as outlined in the 500 series material technical specifications provided herein. M 26 ITEM 400- UNDERGROUND PIPING CONSTRUCTION 2. Upper Portion of Trench (final backfill). From the six(6")or twelve(12") inches above the top of the pipe upward, the type of backfill for various locations shall be as follows: a. Concrete or Asphalt Pavement. The trench shall be filled to two (2") inches below the bottom of the existing flexible base(or concrete pavement)with a mixture of clean sand and 1-1/2 sacks of cement per cubic yard. This material shall be placed in layers not more than six(6") inches thick and thoroughly tamped by mechanical or hand tamping, as directed by the Engineer. The Contractor may use,with prior approval from the Engineer, select native material in lieu of the sand-cement mixture. The select native material must be compacted to 90% density as measured by the Standard Proctor Density Test. Cost of testing shall be borne by the Owner. No further backfill is required for concrete pavement. Flexible base shall be replaced to the bottom of the pavement with a compacted base material, consisting of crushed limestone, iron ore gravel, or a sand-shell mixture. This requirement shall apply to all trenches running underneath surfaced streets, whether crossing the pavement or running along the street. b. Unsurfaced Streets. The trench shall be backfilled with selected loose, fine excavated material by means of water tamping or power tamping. The Engineer may require power tamping for heavily traveled streets. In using water tamping, the trench shall be filled to ten (10") inches below the surface with the loose fine material in even layers not exceeding eighteen (18") inches in thickness of loose material and immediately flooded to complete saturation and left undisturbed for three(3)days. The trench shall then be refilled and flooded again using poles to insure penetration of water to full depth of the trench. This flooding shall continue until there is no further settlement. Power tamping will be permitted only where the trench and backfill material are dry enough to permit satisfactory compaction. Backfill shall be placed in the trench in layers not exceeding twelve (12") inches in thickness. The top ten (10") inches of the trench shall be backfilled with shell or crushed limestone. On completion of the tamping, all of the excavated material shall be substantially replaced in the trench deducting the space occupied by the pipe, bedding, and shell or limestone. Compaction in all levels from six(6") inches or twelve(12") inches above the top of pipe to ten (10") inches below grade shall be not less than ninety (90%) percent of the maximum density value as determined by the "Standard Laboratory Method for Compaction and Density of Soil, AASHTO Designation T-99". The above procedure for unsurfaced streets shall apply in trenches runn ing in and parallel to and running across the normally maintained portion of the road or street right-of-way. c. Trench Within Right-of-Way, but Outside Pavement. Trenches within the right-of-way ofa surfaced street shall be backfilled according to the procedure for an unsurfaced street, except that the shell or crushed limestone in the top ten (10") inches of the trench shall be placed only in driveway crossings, roadway shoulders, and other areas where there M 27 ITEM 400 - UNDERGROUND PIPING CONSTRUCTION will be light traffic. Where the shell is omitted the ground shall be restored to its original condition by the replacement of grass or any other improvement which existed before the construction or which are shown on the plans to be constructed. d. Trenches Away from Streets. Whenever the trench is not in a street but in an easement or plant area, which is not traveled, the backfill procedure shall be the same as for an unsurfaced street,except that the top ten (10") inches of shell or crushed limestone shall be omitted. 400.16 - REMOVAL AND REPLACEMENT OF STREET OR DRIVEWAY SURFACES ORSIDEWALKS AND INSTALLATION OF NEW SIDEWALKS When any portion of a street, driveway, or parking lot surface must be removed for the installation of lines or appurtenances, the Contractor shall remove and replace the pavement as specified below. 1. Concrete Pavement (with or without asphalt overlay). The pavement shall be removed to a distance not less than twelve inches (12") back from a firm bank of the trench excavation. The Contractor shall not use equipment to cut trenches in existing pavements which will strike a heavier blow than is usual with a hand pavement breaker operated from an air compressor. The edges of the cut shall be trimmed so as to leave a vertical face of sound, unfractured pavement. If concrete pavement without overlay is encountered,the top three(3")inches shall be saw cut. Replacement of concrete pavement shall be according to the details in the plans. Unless otherwise specified,concrete pavement shall be replaced to its original depth plus two inches. All replaced pavement shall be finished in a neat and workmanlike manner and protected and cured as its nature may require. Any asphalt overlay shall be replaced with asphaltic concrete so as to make a smooth joint with adjacent pavement. 2. Flexible Base Asphalt Pavement. The pavement and flexible base shall be removed to a distance not less than twelve (12") inches back from a firm bank of the trench excavation. The edges of the cut shall be smooth and vertical.The base shall be replaced to its original depth plus two (2") inches. The surface shall be replaced with asphaltic concrete so as to make a smooth joint with adjacent pavement. 3. Curb and Gutter. If the Contractor removes any curb and gutter in order to install lines or appurtenances, he shall replace it at his own expense. The replacement curb and gutter shall be similar to that removed, and shall be at least equal in quality. 4. Concrete Sidewalks. The Contractor shall replace at his own expense any concrete sidewalk removed or damaged during line construction. The replacement sidewalk shall be of the same width and thickness as that removed, and shall be at least equal in quality. 1 New sidewalks shall be of the same width, thickness and quality as adjacent sections of replacement sidewalk. 1 5. Time of Replacement. The Contractor may replace concrete or asphaltic pavement immediately after completion of trench backfilling,or he may wait until the line has passed an M 28 ITEM 400- UNDERGROUND PIPING CONSTRUCTION exfiltration test. If pavement replacement is not made within seventy-two (72) hours after backfilling, the Contractor shall restore and maintain the roadway at his own expense until the time of replacement. For this purpose he shall provide enough temporary base material and/or surfacing to bring the roadway up to grade. Curbs, gutters, and sidewalks shall be replaced without undue delay. 400.17 - SPECIAL CROSSINGS 1. Major Streets a. General. Crossings of major streets shall be made by the open-cut method. The Contractor shall notify the street superintendent for the Owner at least two (2) days prior to beginning construction of crossings. The Contractor shall maintain all necessary barricades, signs, flares and flagmen for traffic protection, and shall restore the site to its original condition. b. Construction Methods. The Contractor shall saw cut the existing asphalt surface full depth a minimum 12" outside the required trench width of the size pipe being installed prior to excavation. After installation of the proposed line, the contractor shall backfill the trench with cement stabilized sand containing 1 1/2 sacks of cement per cubic yard compacted in place. Replacement of asphalt shall be in accordance with Item 400.17. 2. Stream Beds. Where shown on the plans or designated by the Engineer, the Contractor shall encase the line in quick-set concrete as specified in Item 200 (3000 psi, 2" max. aggregate size). The encasement shall extend a minimum of six (6") inches outside the pipe in all directions. The trench shall be dewatered if necessary, and the trench bottom shall be firm enough to prevent settlement of the concrete. 3. Streams and Ditches. Water and sewer lines which cross streams or ditches above the flow line shall be constructed according to the plans, or as directed by the Engineer. 4. Crossings (or Parallel Construction) of Water and Sewer Lines. All crossings or parallel construction of water and sewer lines shall conform to section 290.44 Water Distribution, of Chapter 290, Rules and Regulations for Public Water Systems as adopted by the Texas Water Commission, effective March 1, 1993. These requirements shall apply whether the water line, the sewer line, or both are new construction. 5. CasingSection. Casings shall be steel pipe, coated on the outside with coal tare epoxy g p p p xy (20 mil minimum thickness). Minimum thickness shall be IA" for I.D. less than 24", 5/16"for I.D. 24" and larger. The diameter (if not specified in plans and specifications) shall be sufficient to allow installation of the carrier pipe (including joints). Any joints in casing shall be welded. Casing may be installed by trenching except where boring is specified. Boring shall be in accordance with the latest Texas State Department of Highways Standard Specifications, unless otherwise specified. 400.18 - EXCESS EXCAVATION M 29 ITEM 400- UNDERGROUND PIPING CONSTRUCTION Excess excavation shall be hauled to and placed on properties designated by the Owner. Once each week the Contractor shall spread the deposited excavation at the site as directed by the Owner. If no site is designated by the Owner,then it shall be the responsibility of the Contractor to dispose of this material in a safe and legal manner. 400.19 - INFILTRATION AND/OR EXFILTRATION AND TESTING Infiltration and/or exfiltration in gravity sanitary sewer lines shall not exceed two hundred (200) gallons per inch of diameter per day per mile of pipe. Sewer lines shall be tested for exfiltration according to Item 450 of these specifications. Water lines shall be sterilized and tested in accordance with applicable specifications. 400.20 - CLEAN-UP The Contractor shall remove from the work site all temporary structures, rubbish, and waste material including all excess excavated materials. The completed clean up shall not be greater than one thousand (1000') feet behind the pipe laying operation. Pipe laying operations will be suspended temporarily if completed clean up is further behind than one thousand (1000')feet. Clean-up requirements shall also apply to any public or private property used by the Contractor for constructing the project, such as temporary storage or field office sites. 400.21 - PAYMENT Pipe will be measured by the linear foot of pipe complete in place. Such measurement will be made between the ends of the pipe barrel along the center axis as installed. The cost of connecting bands or couplings, as in the case of asbestos cement pipe, shall be included in the unit price of pipe. Special fittings, such as tees, bends, etc., which have unit cost set up in the Bid Proposal shall be deducted from the total length of pipe. When pipe is to be paid for according to depth, the depth will be measured from natural ground to the invert of the pipe. Measurements will be taken at 200-foot intervals, or more often if the terrain requires it. Those materials, i.e. sand, 60/40 mix and cement stabilized material used in the bedding and backfill and which are required by Item 400, Item 500 or by the specifications of the pipe manufacturer will not be pay items. The cost of materials and installation will be included in the price bid per linear foot for pipe. All special embedment materials as described in 400.9.7 if ordered by the Engineer shall be paid for at the unit price bid per cubic yard based on quantities taken from truck tickets. Pipe construction will be paid for according to the applicable unit bid prices as follows: Water or sewerline (general) Linear foot of specified size, type and depth or other classification. M 30 ITEM 400- UNDERGROUND PIPING CONSTRUCTION Water or sewerline embedded in concrete Same as general, embedment will be separate pay item. Pipe laid in tunnels and casing Unit price for pipe per linear foot in tunnel or casing. The following items will be paid for at the appropriate unit price,where shown on the bid proposal. Otherwise no separate payment shall be made. Tunnel or casing installation Unit price bid per lineal foot for tunnel or casing. Dewatering of trenches by well point Unit price bid per linear foot of trench if Engineer gives prior approval. No separate payment for other dewatering methods. Replacement of sidewalks, driveway cuts Unit price bid per linear foot. and placement of new sidewalks Replacement of street surfacing Unit price bid per linear foot for type of street.

Access pits for tunnels, shoring of pits, furnishing and installing of liner or casing, backpacking, grouting, lighting, ventilation, and disposal of excavated material. M31 ITEM 405- PIPE BURSTING /CRUSHING 405.01 -GENERAL This specification defines the approved methods and materials for the rehabilitation of existing gravity sewer lines by the Pipe Bursting or Pipe Crushing (Pipe Bursting/Crushing) process. The Pipe bursting process is defined as the reconstruction of gravity sewer pipe by installing an approved pipe material. Essentially the process involves the use of a hydraulic"moling"device or pneumatic hammer, suitable sized to break out the old pipe or using a modified boring "knife" with a flared plug that implodes and crushes the existing sewer pipe. Forward progress of the "mole" or the"knife"may be aided by the use of a hydraulic winch. Pipe bursting by static pull method is also acceptable. The replacement pipe is either pulled or pushed by means of hydraulic force into place, size on size and/or upsizing. 405.02-MATERIAL SPECIFICATIONS A. Solid Wall Polyethylene Pipe(HDPE). 1. The replacement pipe shall be manufactured from a high density high molecular weight polyethylene resin which conforms to ASTM D-1248 and meets the requirements for Type III, Class A, Grade P34, Category 5, and has a PPI rating of PE 3408, when compounded. The pipe produced from this resin shall have a minimum cell classification of 345434D or E (inner wall shall be light in color) under ASTM D3350. Before beginning work, the Contractor shall submit to the Engineer for approval, the vendor's specific technical data with complete physical properties of pipe and pipe dimensions pertinent to this job. A certificate of "Compliance with Specification" shall be furnished for all materials to be supplied. 2.

The Contractor shall select one of these procedures for each new line, according to ground water conditions, subject to the approval of the Engineer. (Air testing is required for vitrified clay sewer lines). Leakage testing is not required for partial replacement of existing manhole segments. All new manholes shall be tested, as described in Item 450.08 below. 450.03 -GROUND WATER LEVEL Before conducting an air, exfiltration, or infiltration test on one or more adjacent line segments(the test section), the Contractor shall determine the ground water level at 400 foot intervals within thetest section. Each interval shall have a two (2") inch vertical pipe set in the ground it for this purpose. Some existing manholes may have this device or another device previously installed forthis purpose. Before testing the sewer lines, the Contractor shall insert a small rod into each two (2") inch pipe along the test section to determine the level of ground water in the pipe. If an existing manhole along the test section contains a nipple or other device for this purpose, the Contractor shall determine the ground water level by means of this device if practical. All ground water measurements shall be converted to depth of ground water above the pipe invert of the test section. The ground water depth for the test section shall be taken as the greatest depth so calculated. If no reliable measurement can be made,the ground water depth shall be taken as the greatest line depth along the test section. 450.04 -AIR TEST(PIPE OTHER THAN VCP) (Allowed for Lines Smaller Than 36" Only) When air testing is selected (for sewers other than vitrified clay), the Contractor shall conduct the test as follows. A. Conduct the test between two (2) consecutive manholes, as directed by the Engineer. B. Plug the test section at each end. One of the plugs used at the manhole shall be tapped and equipped for the air inlet connection for filling the line from an air compressor. C. Make sure that all plugs are properly braced against the internal pressure to prevent air leakage by slippage and blowouts. D. Connect air hose to tapped plug selected for the air inlet. Then connect the other end of the air hose to the portable air control equipment which consists of valves and pressure gauges used (a) to control the air entry rate to the test section, and (b)to monitor the air pressure in the pipe line. M 45 ITEM 450-TESTING SANITARY SEWER LINES More specifically, the air control equipment shall include a shut-off valve, a pressure regulating valve, a pressure reduction valve, and a monitoring pressure gauge having a pressure range from zero(0)to fifteen (15)psi. The gauge shall have a minimum division of 0.10 psi and an accuracy of+ 0.04 psi. E. Connect another air hose between the air compressor and the air control equipment. F. Supply air to the test section slowly, filling the pipe line to a constant pressure of 3.5 psig plus 0.433 psi for each foot of ground water depth above the invert of the pipe. The air pressure must be regulated to prevent the pressure inside the pipe from exceeding 15.0 psig. G. When constant pressure of 3.5 psig plus ground water pressure adjustment (GWP) is reached, throttle the air supply to maintain the internal pressure above 3.0 psig plus GWP for at least five(5) minutes. If leakage is detected at any cap or plug, release the pressure in the line and tighten or repair the faulty plug. A new five (5) minute interval must be allowed afterthe pipe line has been refilled. H. After the stabilization period, adjust the air pressure to 3.75 psig plus GWP and shut off or disconnect the air supply. Commence timing when the air pressure reaches 3.5 psig + GWP with a stopwatch which is allowed to run until the line pressure drops to 2.5 psig plus GWP, at which time the stopwatch is stopped. The time required, as shown on the stopwatch, for a pressure loss from 3.5 psig to 2.5 psig is used to compute the air loss. I. If the time, in minutes and seconds, for the air pressure to drop 0.5 psig is greater than that calculated using the equation below, the test section shall have passed. J. If the time is less than calculated using the equation below, the test section shall not have passed and adequate repairs must be made.

Conduct the test between two(2) or more adjacent manholes, as directed by the Engineer. M 46 ITEM 450-TESTING SANITARY SEWER LINES B. The length of the test section shall be determined by field measurement by the Engineer. C. Plug all inlets and outlets at upstream manhole except the one for the line being tested. D. Cap or plug all service laterals, stubs, and fittings into the test section, so as to prevent ground water from coming in at these connections. E. When the test section consists of more than one manhole sections, plug all connecting sewer lines from intermediate manholes (unless the tributary lines are part of the test section). F. Place V-notch weir into the upstream pipe in the downstream manhole where the measurement will be recorded.The weir shall be installed so as to maintain a watertight seal between the weir and the interior surface of the pipe to prevent water bypassing the V-notch weir. G. V-notch weirs shall be constructed to a high degree of accuracy to avoid erroneous measurements. All weirs used for testing shall be approved by the Engineer. H. After V-notch weir has been installed, allow sufficient time for the infiltrating water to build up and level off behind the weir, until a steady, uniform flow passes over the V-notch weir. I. Measurements can be taken after steady flow occurs over the V-notch weir. Leakage shall be determined from the readings, either directly or by converting the readings of the flow into terms of gallons/(inch diam.--mile--day). Caution shall be taken in recording the readings due to possible variations in flow resulting from local conditions. All weir readings shall be made under the direction of the Engineer's representative. J. Repair and retest any test section exceeding the infiltration limits prescribed in Item 450.10 below. 450.07 -EXFILTRATION TEST PROCEDURES (SEWER LINES) When exfiltration testing is selected,the Contractor shall conduct the test as follows: A. Conduct the test between two(2) or more adjacent manholes, as directed by the Engineer. B. The length of the test section shall be determined by the Engineer. C. All service laterals, stubs, and fittings into the sewer line being tested shall be properly capped or plugged, and carefully braced to resist the thrust actions developed by the internal water pressure. D. Insert and tighten a tapped plug in each of the following locations: 1. Inlet pipe of downstream manhole, for connecting the water supply for filling the sewer. 2. Outlet pipe of upstream manhole, for connection to standpipe. M 47 ITEM 450-TESTING SANITARY SEWER LINES E. Place the standpipe in the upper manhole and connect it to the tapped plug. The standpipe shall be capable of handling from ten (10') feet to twenty-five (25') feet of water head to determine the tightness and soundness of the sewer line, as specified and directed by the Engineer. F. Introduce water into the line through the downstream manhole until the standpipe in the upstream manhole has been completely filled. G. Allow the line to stand for several hours after filling with water, before beginning the test. During this time some water absorption into the manhole structures and sewer pipe will take place. After the water absorption has stabilized, check the water level in the standpipe and add water if necessary. H. The test is now ready to begin. Measure and record the drop in the standpipe over a fifteen (15) minute period. To verify the first results, conduct a second fifteen (15) minute test. I. Convert the measured drops in the standpipe to leakage in terms of gallons/(inch diameter-- mile--day). J. Repair and retest any test section exceeding the infiltration limits prescribed in Item 450.10 below. 450.08 -TEST PROCEDURES (MANHOLES) The Contractor shall test each new manhole by an exfiltration test, as required by the following TCEQ Regulations. A. Hydrostatic Testing. Manholes shall be tested for leakage separately and independently of the wastewater lines by hydrostatic exfiltration testing, vacuum testing, or other methods acceptable to the commission. If a manhole fails a leakage test, the manhole must be made water tight and retested. The maximum leakage for hydrostatic testing shall be 0.025 gallons per foot diameter per foot of manhole depth per hour. Alternative test methods must ensure compliance with the above allowable leakage. Hydrostatic exfiltration testing shall be performed as follows: all wastewater lines coming into the manhole shall be sealed with an internal pipe plug, then the manhole shall be filled with water and maintained full for at least one hour. For concrete manholes a wetting period of 24 hours may be used prior to testing in order to allow saturation of the concrete. B. Vacuum Testing. To perform a vacuum test, on the owner shall plug all lift holes and exterior joints with a non-shrink grout and plug all pipes entering the manhole. No grout must be placed in horizontal joints before testing. Stub-outs, manhole boots, and pipe plugs must be secured to prevent movement while the vacuum is drawn. The owner shall use a minimum 60-inch/Ib torque wrench to tighten the external clamps that secure the test cover to the top of the manhole. The test head must be placed at the inside of the top of the cone section, and the seal inflated in accordance with the manufacturer's recommendations. There must be a vacuum of 10 inches (4.912 psi) of mercury inside the manhole to perform a valid test. The test does not begin until after the vacuum pump is off. The manhole passes the test if after 2 minutes and with all valves closed, the vacuum is at least 9 inches (4.421 psi) of mercury. 450.09 -TEST RESULTS M 48 ITEM 450-TESTING SANITARY SEWER LINES The Contractor shall furnish the test results in triplicate following the format of the form at the end of this section. Testing shall be performed as soon as practical after completing a section of sewer line. No more than 3000 feet of sewer may be laid without testing having been completed up to and including the last manhole in the line. 450.10 - INFILTRATION/EXFILTRATION LIMITS The maximum allowable infiltration/exfiltration rate shall be fifty (50) gallons/(inch diameter--mile-- day). 450.11 -DEFLECTION TESTING Deflection test shall be performed on all flexible and semi-rigid pipe. The test shall be conducted after the final backfill has been in place at least thirty (30) days. No pipe shall exceed a deflection of five percent (5%). If the deflection test is to be run using a rigid ball or mandrel, it shall have a diameter equal to ninety-five percent (95%) of the inside diameter of the pipe. The test shall be performed without mechanical pulling devices. 450.12 - PAYMENT No separate payment shall be made for testing of sewer lines and manholes. This work shall be included in the unit prices bid for the lines and manholes.
