Payments to Contractor and Completion 1. Schedules The schedule of values established as provided in paragraph C.7 will serve as the basis for progress payments and will be incorporated into a form of Application for Payment.

The contractor shall, on the 25th day of each , calendar month, together with a representative of the Engineer, make an estimate of the value of the work performed as of the 15th day of the month in accordance with this Contract since the last preceding estimate was made. The Contractor shall then prepare and submit the estimate to the Engineer on the periodical estimate for partial payment forms, copies of which are bound with these Contract Documents. The number of copies to be submitted will be determined by the Engineer after construction has started. b. Upon presentation of certified copies of purchase 1 bills and freight bills, the Owner will permit inclusion in such monthly estimates payment for ' materials that will eventually be incorporated in the project, providing that such material is suitably stored on the site at the time of submission of the estimate for payment. At the time the next following monthly estimate is submitted, certified copies of receipted purchase and freight bills for the stored materials included in the monthly payment estimate submitted two months previously shall be submitted. If the Contractor fails to submit proof of payment with the monthly payment estimate, those items of stored materials for which no proof of payment has been submitted will be deleted from the current payment estimate. Such materials when so paid for by the Owner will become the property of the Owner and, in case of default on the part of the Contractor, the Owner may use or cause to be used by others these materials in construction of the project. However, the Contractor shall be responsible for safe guarding such materials against loss or damage of any nature whatsoever, and in case of any loss or damage the Contractor shall replace such lost or damaged materials at no cost to the Owner. , General Conditions 68 City of Fayetteville ' Sanitary Sewer Improvements H Paragraph O.2.b continued (1) Except as provided in paragraph O.2.b, the first ' application for payment shall be of the value of the work done and of materials proposed and suitable for permanent incorporation in the work, delivered, and suitably and safely stored at the site of the work since the Contractor shall have begun the performance of this ' Contract; and every subsequent estimate, except the final estimate, shall be of value of the work done and materials delivered and suitably stored at the site of the work since the last ' preceding estimate was made. c. No application for partial payment shall be made when, in the judgement of the Engineer, the total value of the Work done and materials incorporated into the Work under this Contract since the last preceding estimate amount is less than $10,000. 1 d. Applications for payment shall be signed by the Engineer and approved by the Owner, and after such I I I] I I I I I 1l approval, the Owner, subject to the foregoing provisions, will pay or cause to be paid an amount equal to the estimated value of the work performed less a retained amount in accordance with the following schedule: (1) Ten (10) percent until construction is 50 percent complete. (2) Five (5) percent after construction is 50 percent complete, provided that the Contractor is making adequate progress and there is no specific cause for greater withholding. (3) When the project is substantially complete (operational or beneficial use as determined by the Engineer) the retained amount will be reduced to two (2) percent of the value of work which is substantially complete, or two hundred (200) percent of the value of each item as determined by the Engineer to complete said item or items of work, whichever is greater. e. Contractor shall furnish with each application for payment a Contractor's sworn affidavit listing all parties to receive payments on that request. 69 General Conditions City of Fayetteville Sanitary Sewer improvements Paragraph O.2 continued f. If required by the regulatory agencies, the Contractor and his subcontractor shall prepare weekly sworn affidavits with respect to the payment of wages in accordance with the provisions as set forth in the "Anti -Kickback" Act, and submit affidavits with the progress payment requests. 3. Unit Price Items a. Unit price items listed in the Bid form and in the Agreement form may be of two types, "unit price construction items", and "unit price work items ordered by the Engineer during construction". For all unit price items quantities as set forth are the best estimates which can be made during design, since actual quantities cannot be determined until ,;construction is underway. b. The Contractor shall study carefully the Specifications to determine the extent and scope of the work included under lump sum items in the Contract. It may be that work under some unit price items is in addition to similar work to be performed under lump sum items and paid for thereunder. C. Unit Price Construction Items Unit price construction items will be used to pay for work not included under a lump sum item but required by the Contract. d. •Unit Price Work Items Order by the Engineer During Construction These unit price items will be used to pay for designated work, not shown on the Contract Drawings, when ordered by the Engineer in writing during construction.

Reporting and Invoicing Cost -of -work I All cost -of -work items shall be reported daily and signed by the Contractor and the Engineer, which daily reports shall thereafter be considered the true record of cost- of- work done. Completely detailed invoices covering the cost -of -work shall be submitted for payment not later than 15, days after the completion of the work. The charges for work performed by the Contractor, by a Subcontractor, and by an employee of a Subcontractor shall be reported separately.

Partial Waiver of Liens Partial waiver of liens shall accompany each payment request to cover the full amount of the previous payment request. The Contractor shall procure from each and every subcontractor and suppliers of material or labor a partial waiver of lien to release the Owner of any claim to a mechanics lien, which they or any of them may have under the mechanics lien laws of the State in which the project is located. Any payments made by the owner without requiring strict compliance to the terms of this paragraph shall not be construed as a waiver by the Owner of the right to insist upon strict compliance with the terms of this approach as a condition of later payments. 6. Contractor's Warranty of Title Contractor warrants and guarantees that title to all work, materials and equipment covered by any Application for Payment, whether incorporated in the project or not, will pass to Owner no later than the time of payment free and clear of all Liens. 7. Review of Progress Payment Requests a. Engineer will, within fifteen (15) days after receipt of each payment request, either indicate in writing a recommendation of payment and present the request to Owner, or return the payment request 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 request. Thirty (30) days after presentation of the Application for Payment with Engineer's recommendation, the amount recommended will (subject to the provisions of paragraph O.7.f) become due and when due will be paid by Owner to Contractor. b. If the Owner fails to make payment thirty (30) days after review by the Engineer, in addition to other remedies available to the Contractor, there may be added to each such payment interest at an annual rate of twelve (12) percent commencing on the first day after said payment is due and continuing until the payment is received by the Contractor. 71 Genera] Conditions City of Fayetteville Sanitary Sewer Improvements Lfl Paragraph 0.7 continued I C. Engineer's recommendation of any payment requested in a payment request will constitute a representation by Engineer to Owner, based on Engineer's on -site observations of the work in progress as an experienced and qualified design professional and on Engineer's review of the payment request and the accompanying data and schedules that the Work has progressed to the point indicated; that, to the best of the Engineer's knowledge, information and belief, the quality of the work is in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon substantial completion, to the results of any subsequent tests called for in the Contract Documents to a final determination of quantities and classifications for Unit Price Work under paragraph 3.8 and to any other qualifications stated in the recommendation); and that Contractor is entitled to payment of the amount recommended. However, by recommending any such payment, Engineer will not thereby be deemed to have represented that exhaustive or continuous on -site observations have been made to check the quality or the quantity of the work, or that the means, methods, techniques, sequences, and procedures of construction have been reviewed or that any examination has been made to ascertain how or for what purpose Contractor has used the moneys paid or to be paid to Contractor on account of the Contract Price, or that title to any work, materials or equipment has passed to Owner free and clear of any Liens. d. Engineer's recommendation of final payment will constitute an additional representation by Engineer to Owner that the conditions precedent to Contractor's being entitled to final payment as set forth in paragraph 0.8.a have been fulfilled. e. Engineer may refuse part of any payment would be incorrect I I I I I I I I I iI I to recommend the whole or any if, in Engineer's opinion, it to make such representations to Owner. Engineer may also refuse to recommend any such payment, or, because of subsequently discovered evidence or the results of subsequent observations or tests, nullify any such payment previously recommended; to such extent as may be necessary to Engineer's opinion to protect Owner from loss because: (1) The Work is defective, or completed work has been damaged requiring correction or replacement. General Conditions 72 City of Fayetteville Sanitary Sewer Improvements I [1 I I IParagraph O.7.e continued (2) The Contract Price has been reduced by Written 'Amendment or Change Order. (3) Owner has been required to correct defective Work or complete the Work in accordance with paragraph N.6.b.

Owner may refuse to make payment of the full amount recommended by Engineer because claims have been made against owner on account of Contractor's performance or furnishing of the Work or Liens have been filed in connection with the Work or there are other items entitling Owner to a set-off against the amount recommended, but Owner must give Contractor immediate written notice (with a copy to Engineer) stating the reasons for such action. 8. Substantial Completion a. When Contractor considers the entire work ready for its intended use and all final restoration and testing is complete, Contractor shall notify Owner and Engineer in writing the entire Work is Substantially Complete and request that Engineer issue a Statement of Substantial Completion. Within a reasonable time thereafter, Owner, Contractor and Engineer shall make an observation 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 his reasons therefore. If Engineer considers the work substantially complete, Engineer will prepare and deliver to Owner a tentative Statement of Substantial Completion which shall fix the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment. This list shall be called a punch list. Owner shall have fourteen (14) days after receipt of the tentative certificate during which he may make written objection to Engineer as to any provisions of the certificate or attached list. If, after considering such objections, Engineer concludes that the Work is not Substantially Complete, Engineer will within fourteen days after submission of the tentative certificate to Owner notify Contractor in writing, stating his reasons therefore. If, after consideration of Owner's objections, Engineer i3 General Conditions City of Fayetteville Sanitary Sewer Improvements I Paragraph O.8.a continued I considers the Work Substantially Complete, Engineer will within said fourteen (14) days execute and deliver to owner and Contractor a definitive Statement of Substantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as Engineer believes justified after consideration of any objections from Owner. At the time of delivery of the tentative Statement of Substantial Completion Engineer will deliver to owner and Contractor a written recommendation as to division of responsibilities pending final payment between Owner and Contractor with respect to security, operation, safety, maintenance, heat, utilities and insurance and warranties. Unless Owner and Contractor agree otherwise in writing and so inform Engineer prior to Engineer's issuing the definitive Statement of Substantial Completion, Engineer's aforesaid recommendation will be binding on Owner and Contractor until final payment. b. Owner shall have the right to exclude Contractor from the work after the date of Substantial Completion, but Owner shall allow Contractor reasonable access to complete or correct items on the punch list. 9. Partial Utilization , a. Use by Owner of any finished 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 useable part of the Work that can be used by Owner without significant interference with Contractor's performance of the remainder of the work, may be accomplished prior Substantial Completion of all the Work subject to the following: (1) Owner at any time may request Contractor in writing to permit Owner to use any part of the ' work which Owner believes to be ready for its intended use and substantially complete. If Contractor agrees, Contractor will certify to Owner and Engineer that said part of the Work is substantially complete and request Engineer to issue a Statement of Substantial Completion for that part of the Work. Contractor at any time may notify Owner and Engineer in writing that Contractor considers any such part of the Work ready for its intended use and substantially complete and request Engineer to issue a General Conditions 74 ' City of Fayetteville Sanitary Sewer Improvements I H 'J I I I I I I I I I I [1 I I I Paragraph 0.9.a continued Statement of Substantial Completion for that part of the Work. Within a reasonable time after either such request, Owner and Contractor shall observe 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 therefore. If Engineer considers that part of the Work to be substantially complete, the provisions of paragraph 0.8 will apply with respect to Statement of Substantial Completion of that part of the Work and the division of responsibility in respect thereof and access thereto. (2) Owner may at any time request Contractor in writing to permit Owner to take over operation of any such part of the Work although it is not substantially complete. A copy of such request will be sent to Engineer and within a reasonable time thereafter Owner, Contractor, and Engineer shall observe that part of the Work to determine its status of completion and will prepare a list of the items remaining to be completed or corrected thereon before final payment. If Contractor does not object in writing to Owner and Engineer that such part of the Work is not ready for separate operation by Owner, Engineer will finalize the list of items to completed or corrected and will deliver such list to Owner and Contractor together with a written recommendation as to the division of responsibilities pending final payment between Owner and Contractor with respect to security, operation, safety, maintenance, utilities, insurance, warranties and guarantees for that part of the Work which will become binding upon Owner and Contractor at the time when Owner takes over such operation (unless they shall have otherwise agreed in writing and so informed Engineer). During such operation and prior to Substantial Completion of such part of the Work, Owner shall allow Contractor reasonable access to complete or correct items on said list and to complete other related Work.

Deflection testing shall be required for polyvinylchloride pipe. Where the new sewer constructed replaces an existing sewer with active service ' connections, only internal inspection during high groundwater conditions shall be required. The Engineer may require individual joints to be pressure tested. If ' all joint test results conform to the specified leakage then the cost of the test will be paid for by the Owner. If any joint test results do not conform to specified leakage, then the cost of the test and repairs required to properly instal the pipe will be paid for by the Contractor and at no additional cost to the Owner. ' D1-9(1) City cf Fayetteville Sewer System Improvements I .Replacement sewers and service laterals that parallel or cross storm drains or ditch sections shall also be tested in accordance with Section D1 -8.C.1 to determine that inflow has been eliminated from the sewer system. ' B. Materials Not specified. C. Execution 1. Alignment and Grade , Check alignment, grade and visible infiltration by methods of visual internal inspection; and by television inspection. Laser equipment is recommended to test the pipe grade and alignment. a. Visual Internal Inspection 1) Clean pipe of excess mortar, joint sealant and other dirt and debris prior to inspection. 2) Inspect sewer by flashing a light between manhole and/or by physical passage where space permits. Determine from illumination and/or physical inspection the presence of any misaligned, displaced, or broken pipe and the presence of visible infiltration or other defects. b. .Internally inspect each line segment utilizing a closed circuit color television camera in the presence of the Engineer. In addition, provide a video tape of the sewer line to the Engineer with tapes to become the property of the Owner following completion of testing. El I 2. Infiltration Conduct infiltration tests on sewers before acceptance by the Owner. For -sewers with a diameter less than twenty-four (24) inches, the infiltration-exfiltration shall not exceed two hundred (200) gallons per day per inch of nominal diameter per mile of sewer line for any section of the system. For sewers with a diameter twenty-four (24) inches or greater, infiltration- exfiltration shall not exceed six thousand (6,000) gallons per day per mile -of pipe. J I City of Fayetteville D1-9(2) Sewer System Improvements I ' Install weirs or other suitable flowrate measuring devices adequate to determine to the satisfaction of the ' Engineer that the specified infiltration limit is not exceeded for the reach of gravity sewer where evidence of infiltration is discovered. Where the specified infiltration limit is exceeded, repair or replace the defective reach of pipeline. Following repair of defective reaches of pipeline, remeasure infiltration flowrates and make additional repairs until an ' acceptable infiltration flowrate is achieved. 3. Low Pressure Air Testing of Gravity Systems ' (Exfiltration) a. Test manholes in accordance with Section D1-7. ' b. Pipelines Test each section of gravity pipeline between ' manholes and/or structures after backfilling, separately with equipment and methods as outlined below.

Concrete pipe must pass a weir ' test. 2) Furnish facilities required including necessary piping connections, test pumping equipment, pressure gauges, bulkheads, regulator to avoid overpressurization, and miscellaneous items required. a) The pipe plug for introducing air to the sewer line shall be equipped with two taps. ' one tap will be used to introduce air into the line being tested through suitable valves and fittings, so that the input air may be regulated. The second tap will be ' fitted with valves and fittings to accept a pressure test gauge indicating internal pressure in the sewer pipe. Additional ' valve and fitting will be incorporated on the tap used to check internal pressure so that a second test gauge may be attached to the internal pressure tap. The pressure test gauge will also be used to indicate loss of air pressure due to leaks in the sewer line. I ID1-9(3) City of Fayettev-.:ie Sewer Systen Improvements I b) The pressure test gauge shall meet the I following minimum specifications: Size (diameter) 4-1/2 inches Pressure Range 0-15 psi Figure Intervals 1 psi Increments Minor Subdivisions 0.05 psi Pressure Tube Bourdon Tube or diaphragm Accuracy Plus or minus 0.25% of maximum scale reading Dial White coated aluminum with black lettering, 270 degree arc and mirror edge Pipe Connection Low male 1/2 inch N.P.T. Calibration data shall be supplied with all ' pressure test gauges. Certification of pressure test gauge will be required from the gauge manufacturer. This certification and calibration data shall be available to the Engineer whenever air tests are ' performed. 3) Test each reach of sewer pipe between manholes after completion of the installation of pipe and appurtenances and the backfill of sewer trench. 4) Plug ends of line and cap or plug all , connections to withstand internal pressure. One of the plugs provided must have two taps for connecting equipment. After connecting air control equipment to the air hose, monitor air pressure so that internal pressure does not exceed 5.0 psig. After reaching 4.0 psig, throttle the air supply to maintain between 4.0 and 3.5 psig for at least two (2) minutes in order to allow equilibrium between air temperature and pipe walls. During this time, check plugs to detect any leakage. If plugs are found to leak, bleed off air, tighten plugs, and again begin supplying air. After temperature has stabilized, the pressure is allowed to decrease to 3.5 psig. At 3.5 psig, begin timing to determine the time required for pressure to drop to 2.5 psig. If the time, in seconds, for the air pressure to decrease from 3.5 psig to 2.5 psig is greater than that shown in the table below, the pipe shall be presumed free of , defects.

END OF SECTION D2-11 City of Fayetteville D2-11(6) Sewer System Improvements I I I I I I LJ I I I I I I IA 1 1 1 ' B. 1 1 1 1 1 1 1 1 1 D-2-12 CURED -IN -PLACE PIPE (CIPP) General Description The Contractor shall utilize the installation of flexible sewer pipe (CIPP) in accordance with ASTM F1216 to restore the watertight condition of sanitary sewer lines which would otherwise require various point repairs and/or removal of cross connections. Due to existing alignment conditions in the sewers to be lined, only products meeting ASTM F1216 (Installation by Inversion Method) will be accepted. Materials 1. Cured -in -Place Material (CIPP) The flexible tube material shall be a polyester fiber felt tubing lined on one side with polyurethane and fully impregnated with a liquid, thermosetting resin as specified. The polyester felt tubing, including the polyurethane coated felt and the thermosetting resin shall meet manufacturer's standards. The cured pipe shall be a hard impermeable pipe which shall conform to the minimum structural standards applicable including ASTM D-638 for 3,000 psi tensile stress, ASTM D-790 for 4,500 psi for flexural stress, and ASTM D-790 for 400,000 psi for modules of elasticity. The finished liner shall incorporate thermosetting materials which will withstand the corrosive effects of normal sewage. The Contractor shall provide a written guarantee of his compliance with these standards. The tube material shall meet the requirements of ASTM F1216, Section 5.1. The resin system shall meet the requirement of ASTM F1216. The chemical resistance requirements shall conform to ASTM F1216, Appendix 2. 2. Sizing of the CIPP The CIPP diameter, length and wall thickness shall be appropriate for each designated location. The Contractor shall verify the actual sewer lengths and diameters in the field prior to cutting the tube to length and sizing the diameter. D2-12 (1) City of Fayetteville Sewer System Improvements I a. The tube shall be fabricated to a size that when installed will neatly fit the internal circumference of the sewer designated for CIPP. Allowance for circumferential stretching during insertion shall be made as per manufacturer's standards. b. The length of the CIPP shall be that deemed necessary by the Contractor to effectively carry out the insertion and seal at the inlet and outlet points. When cured, the CIPP should extend from end to end of the sewer segment being lined in a continuous tight fitting watertight pipe -within -a - pipe. c. The CIPP shall be 3.5 mm thickness for pipe 6 inches in diameter, 4.5 mm thickness for pipe 8 inches in diameter and 6 mm thickness for pipe 10 inches in diameter, unless otherwise specified on the Drawings. C. Execution I I I I G I 1. General , CIPP installation shall be accomplished by inverting the resin impregnated tube into the existing sanitary sewer pipeline utilizing an inversion standpipe and .hydrostatic head. Curing of the CIPP shall be accomplished by circulating hot water/steam to cure the thermosetting resin into a hard impermeable pipe. 2. Preliminary Cleaning and Inspection a. Prior to CIPP installation of designated sanitary sewer line segments the Contractor shall remove internal deposits as necessary to assure proper liner, installation. b. Inspection of pipelines shall be performed by experienced personnel trained in locating breaks, obstacles, and service connections by closed circuit television. The interior of the pipeline shall be carefully inspected to determine the location and extent of any structural failures, which may prevent proper installation of lining materials into the pipelines and location of service laterals. City of Fayetteville D2-12 (2) Sewer System Improvements I C C I I I I I IC. It shall be the responsibility of the Contractor to clear the line of obstructions such as solids, roots, dropped joints, protruding branch connections or broken pipe that will prevent the insertion of the liner. If inspection reveals an obstruction not indicated in these specifications, ' that cannot be removed by conventional cleaning equipment, then the Contractor shall notify the Engineer. The Engineer may authorize an excavation ' in order to remove such obstruction. 3. Documentation ' Video tapes and a suitable log shall be provided by the Contractor which shall document, to the satisfaction of the Engineer, the condition of the sewer line segment both immediately before and after lining has been installed. The video tapes (VHS) and log shall become the property of the Owner. The Contractor shall review the existing condition of the line and justify to the ' satisfaction of the Engineer any and all point repairs prior to any construction. ' 4. Flow Bypassing The Contractor, when required, shall provide for the ' transfer of flow around the section or sections of pipe that are to be lined. The bypass shall be made by diversion of the flow at an existing upstream access point and pumping the flow into a downstream access ' point or adjacent system. The pump and bypass lines shall be of adequate capacity and size to handle the flow. The proposed bypassing system shall be approved ' in advance by the Owner. 5. Notification of the Public The Contractor shall notify all property owners affected by the CIPP installation work at least 48 hours prior to commencement of the work which will temporarily plug the ' sanitary services of the property owners connected to the sewer line segment being lined. I IJ I [I 6. CIPP Installation a. The Contractor shall designate a location where the uncured resin in the original containers and the unimpregnated liner will be vacuum impregnated prior to installation. The Contractor shall allow the Owner to inspect the material and 'wet out' procedure. A resin and catalyst compatible with D2-12 (3) City of Fayetteville Sewer System Improvements I the requirement of this method shall be used. The quantities of the liquid thermosetting materials shall be in accordance with the manufacturer's standards to provide the lining thickness specified. b. The wet out tube shall be inserted through an existing manhole or other approved access by means I of an inversion process and the application of a hydrostatic head sufficient to fully extend the lining to the next designated access point. The impregnated tube shall be inserted into the inversion standpipe with the impermeable plastic membrane side out. At the lower end of the inversion standpipe, the tube shall be turned inside out .and attached to the inversion standpipe so that a leak proof seal is created. The inversion head will be adjusted to be of sufficient height to invert the liner to the next access point designated and to hold the liner snug to pipe wall and to produce dimples at side connections and flared ends at the entrance and exit access points. The use of a lubricant is recommended and if used such lubricant shall be approved by manufacturer's ' standards. The manufacturer's standards shall be closely followed during the elevated temperature process curing so as not to over stress the felt fiber and cause damage or failure of the liner prior to cure. In certain cases, the Contractor may elect to use a Top Inversion. In this method the tube is pre -inverted to a distance that corresponds to the minimum inversion head and instead of attaching to an elbow at the base of the inversion tube, the liner is attached to a top ring. , c. After inversion is completed the Contractor shall supply a suitable heat source and water recirculation equipment. The equipment shall be capable of delivering hot water to the far end of the liner through a hose, which has been perforated per manufacturer's recommendations, to uniformly raise the water temperature in the entire liner above the temperature required to effect a cure of the resin. This temperature shall be determined by the resin/catalyst system employed. The heat source shall be fitted with suitable monitors to gauge the temperature of the incoming and outgoing heat exchanger circulating water. Thermocouples shall be placed between the tube and the invert at near and far access to determine the temperature of the tube and time of exotherm. Water temperature in the line during the cure period shall not be i City of Fayetteville D2-12 (4) Sewer System Improvements I ' less than 150°F as measured at the heat exchanger return line. Initial cure shall be deemed to be completed when inspection of the exposed portions of the liner appear to be hard and sound and the thermocouples indicate that an exotherm has occurred. The cure period shall be of a duration ' recommended by the resin manufacturer, as modified for the Insituform process, during which time the recirculation of the water and cycling of the heat exchanger to maintain the temperature in the tube shall be continuous. d. The Contractor shall cool the hardened CIPP to a temperature below 100°F before relieving the static head in the inversion standpipe. Cool -down may be accomplished by the introduction of cool water into ' the inversion tube to replace water being drained from a small hole made in the end of the CIPP at the downstream end. Care shall be taken in the release of the static head such that a vacuum will ' not be developed that could damage the newly installed CIPP. ' e. The finished CIPP shall be continuous over the entire length of an insertion run and be as free from visual defects such as foreign inclusions, dry spots, pinholes, and delamination. The CIPP shall be impervious and free of any leakage from the pipe to the surrounding ground or from the ground to the inside of the CIPP. Any defects which will affect, ' in the foreseeable future, or warranty period, the integrity or strength of the CIPP, shall be repaired at the Contractor's expense, in a manner ' mutually agreed by the Owner and the Contractor. 7. Completion of CIPP a. If due to broken or misaligned pipe at the access point, the CIPP fails to make a tight seal, the Contractor shall apply a seal at that point. The seals shall be of a resin mixture compatible with the CIPP. ' b. After the CIPP has been cured, the Contractor shall reconnect the existing active service connections. Reconnection of service connections shall be accomplished by external excavation unless ' otherwise allowed by the Engineer. Any bypass pumping that is required shall be provided at no additional cost for sewer lines where lining is ' being performed. Service interruptions to any homes tributary to this sewer line shall not exceed 18 hours. D2-12 (5) City cf Fayetteville Sewer System Improvements I C. The watertightness of the CIPP shall be gauged while the tube is curing, and under a positive head. After the work is completed, the Contractor will provide the Owner with a video tape showing both the before and after CIPP conditions including the restored connections. Upon completion of the installation work after required testing indicates the CIPP is acceptable, the Contractor shall reinstate the project area affected by his operation and perform any surface restoration in accordance with these Specifications. d. Service connections in CIPP lines shall be reinstated with a saddle unless otherwise directed by the Engineer. Contractor shall remove the appropriate amount of ,carrier pipe to allow the saddle to be directly connected to the outside wall _of the CIPP. An epoxy, meeting the manufacturers recommendation, shall be applied to the saddle to assure a water tight seal between the saddle and insituform liner. The saddle shall be secured with stainless steel bands. After the epoxy has set, the Contractor shall completely encase the saddle and exposed CIPP in concrete. Care shall be used not to damage the CIPP, if damage occurs as a result of the Contractor's operations, the ' Contractor shall assume all cost associated with the repair of the CIPP. , 8. Manhole Connections All cracked or deteriorated material shall be removed I from the area to be sealed. Thoroughly plug the annular space between the liner and the host pipe with resin used to impregnate the liner. Finish grout smooth and flush with the interior manhole wall surface and make watertight with non -shrink grout. 9.
