CURED IN PLACE PIPE LINING SYSTEMS

1.0 INTRODUCTION

1.1 INSTALLATION INTRODUCTION

The liner will be impregnated with a thermal setting resin that will completely wet out the soft flexible absorbent tube. Curing is accomplished by circulating air and steam to cross-link the customized resin into a hard impermeable pipe. When cured the hardened liner will extend from manhole to manhole in a continuous tight fitting watertight pipe-within a pipe, chemically resistant to sewage gases and materials.

ONLY MANUFACTURER CERTIFIED CONTRACTORS WILL BE ALLOWED

TO INSTALL CURED IN PLACE LINER PIPE.

1.2 INTENTION

The intent of this lining process is to line pipes which are subject to partial structural deterioration, partial distortion, interior corrosion, settling, misalignment, cracking, exfiltration and infiltration. The liner will withstand long-term external hydrostatic loading.

1.3 PIPES TO BE LINED

The existing pipes to be lined are 6 inch diameter cast iron pipe (C.I.P), which were installed in the mid 1970’s. Portions of the pipes to be lined pass through a wetland, and one of the manholes is located in a wetland. The pipes to be lined extend between manhole #8and Manhole #8A, Manhole #8A and Manhole #4, and between manhole #4 and the collection manhole at the lift station. See attached drawings for locations. The pipe leading to the dump station has a sweep bend at the dump station. The total length of pipe to be lined is approximately 806 feet based on the following dimensions.

Dump Station to Manhole #8 – 108 feet Manhole #8 to Manhole #8A – 97 feet Manhole #8A to Manhole #4 – 301 feet Manhole # 4 to Lift Station – 300 feet SECTION 33 01 90 Page 2

1.4 SITE CHARACTERISTICS

Manhole # 8 – This manhole is located adjacent to the road in a mowed area near the dump station. Access is good.

Manhole # 8A – Location is unknown but is between manhole #4 and manhole #8.

Dimensions from each manhole are listed above.

Manhole # 4 – Is located in a wooded wetland. Access is limited with trees surrounding the manhole. The water is standing on the surface in the low areas. Access to this manhole will be by the nature trail leading from the game area located west of the manhole and north of the campground road leading to the dump station. This may require clearing brush along the edges of the nature trail.

Collection Manhole at Lift station – The collection manhole at the lift station is located in the equipment storage area off of the south end of the COE shop building. Access is good to this location. Service Connections – There are no service connections to the pipes to be lined.

If the surface is sufficiently rough to cause damage to the impregnated liner material a protector shield may be used to cover the manhole opening and the invert throughout the section to be lined. Next, the impregnated LINER shall be inserted into the existing sewer by a cable attached to the liner and then pulled by a winch.

6.2 PULL IN PLACE

The liner may be drawn into the existing sewer by means of winch cable. With the ends of the liner sealed, the liner will be expanded by compressed air or water. However, the pulling tension shall not exceed more than half of the tensile strength of the liner.

6.3 AIR INFLATION

Initially, compressed air is introduced, inflating and forming the liner material against the inner walls of the pipe to be lined.

6.3 STEAM AND AIR CURING

After the inflation steps are completed, the contractor shall begin the curing process of utilizing the LINER approved heat source. The equipment will be capable of delivering steam to the far end of the liner to uniformly raise the temperature required to effectively cure the resin. The temperature maintained during the curing period shall be that recommended by the resin manufacturer and approved by the engineer.

SECTION 33 01 90 Page 8 During the curing process the heat source shall be fitted with pressure gauges and thermocouples to continuously monitoring the temperature of the incoming and outgoing heat medium supply. The water, steam or air temperature during the cure period shall meet the resin manufacturer's requirements as measured at the heat source inflow and outflow return lines. At the engineer's direction, the contractor shall provide standby equipment to maintain the heat source supply throughout the curing process; the contractor shall maintain static head (internal pressure) in the liner greater than the maximum design external water pressure.

The initial cure shall be deemed complete when inspection shows that the exposed liner portions appear hard and sound and the remote temperature sensors indicate that an exothermic has occurred. The cure period shall be of duration recommended by the resin manufacturer as modified to account for length, thickness and diameter of the liner.

The hardened liner has to be cooled to a temperature below 100 degrees F. After reaching the appropriate temperature, the static head in the lined pipe is relieved. This cool-down period shall be used prior to opening the downstream stopper, reconnecting of services and returning normal flow back into the system. If the cured pipe does not fit tightly against the host pipe at its termination point(s), the voids shall be sealed, by filling them with a resin mixture compatible with the CIPP. All internal (dry or non-bonded) inflation tubes that are not bonded to the resin impregnated tube prior to installation of the liner tube shall be completely removed from the finished cured-in place liner pipe.

Wrinkles in the finished liner pipe that cause a backwater, reduce the pipe's hydraulic capacity or structural stability or that create voids between the liner and pipe wall will be unacceptable. All unacceptable sections shall be removed or repaired by a method approved by the engineer at the contractor's expense. Repair methods shall be proposed by the contractor and submitted to the engineer for approval.

6.4 WATER INVERSION

The wet-out tube shall be inserted through an existing manhole or other approved access by means of an inversion process using water with an application of a hydrostatic head sufficient to fully extend it to the next designated manhole or termination point. The tube shall be inserted in the vertical inversion standpipe so that a leak proof seal is created.

The inversion head shall be adjusted to sufficient height to cause the impregnated tube to invert from point of termination and hold the tube tight to the pipe wall, producing dimples at side connections. Care shall be taken during the inversion so as not to overstress the felt fiber.

SECTION 33 01 90 Page 9

6.5 HEATED WATER CURING

If heated water is used to cure liner, provide a suitable head source, and water recirculation, equipment capable of delivering hot water to the far end of the liner. To quickly and uniformly raise the water temperature in the entire inverted liner to the temperature to commence the exothermic reaction of the resin as determined by the catalyst system employed. The heat source shall be fitted with suitable monitors to gauge the temperatures of the incoming and outgoing water supply to determine when uniform temperature is achieved throughout the length of the liner. Water in the liner shall be raised to a temperature as recommended by the resin manufacturer. Initial cure is deemed to be completed when a uniform temperature as recommended by the resin manufacturer as determined by the water temperature monitors on the heat source, is achieved throughout the length of the liner. The post cured period shall then commence with the heat source shut down but recirculation of the water continued to maintain uniform temperature in the liner. Hot water may be bled out of the system and replaced by clean water at ambient water main temperature to control post cure water complete cure. Time required to cure is a function of the pipeline section diameter and length, an shall be determined by the lining manufacturer's instructions. The curing process should be sufficient to hold the liner tight to the pipe wall and produce dimples at side connections.

After curing, open and drain the line in a manner so a vacuum will not be developed which may damage the installed liner.

6.6 AIR INVERSION

Insert the wet-out tube through an existing manhole or other approved access by means of an inversion process using the application of air pressure sufficient to fully extend it to the next designated manhole or termination point. The tube shall be connected by an attachment at the upper end of the guide chute so that a leakproof seal is created and with the impermeable plastic membranes side out. As the tube enters the guide chute, the tube shall be turned inside out. The inversion air pressure shall be adjusted so that sufficient pressure is provided to cause the impregnated tube to invert from point of termination and hold the tube tight to the pipe wall, producing dimples at side connections. Care shall be taken during the inversion so as not to over stress the woven and non-woven materials.

6.7 HOT AIR

If hot air is used to cure the liner, provide suitable heat source and recirculation equipment to uniformly distribute the heat. The temperature and pressure in the line during the cure period shall be as recommended by the resin manufacturer. Hot air generating equipment shall be equipment with a suitable monitor to gauge the temperature of the outgoing steam. The temperature of the resin being cured shall be monitored by placing gauges between the impregnated tube and the existing pipe at both ends during cure. Initial cure will occur during temperature heat-up and deemed complete when exposed portions of the new liner appear to be hard and sound and the remote temperature sensor SECTION 33 01 90 Page 10 indicate that the temperature is of a magnitude to realize an exotherm or cure in the resin.

After initial cure is reached, the temperature shall be raised to the post cure temperature recommended by the resin manufacturer. Post cure temperature shall be held for a period as recommended by the resin manufacturer. During the post cure time the distribution and control of hot air shall be continued to maintain required temperature. The curing process should be sufficient to hold the liner tight to the wall and produce dimples at side connections. Curing of the liner pipe shall take into account the existing pipe material and size, the resin system and ground conditions, which includes temperature, moisture level and thermal conductivity of soil.

6.8 TRIMMING LINER AT MANHOLES

After the liner has been cured, the contractor will trim any excess liner in the manholes.

6.9 TELEVISION INSPECTION AFTER INSTALLATION

A television inspection and video recording of the newly lined pipe including the restored service connections shall be performed immediately after work is completed. The video recording shall be submitted on a DVD. Should the results of this inspection reveal any defects as defined above, the contractor shall be required to repair or replace these defects as ordered by the Contracting Officer, at no cost to the Government, before the work under the Contract will be considered for substantial completion. The contractor shall furnish and maintain in good condition, all equipment necessary for the proper execution and inspection of the work.

7.0 MEASUREMENT AND PAYMENT

Payment of rehabilitation work will be based on the unit price listed in the bid schedule.

This payment shall include full compensation for all labor, equipment, material, tools, and incidentals for successfully completing the work as specified.

7.1 MEASUREMENT

All measurements shall be as specified or made by conventional means with accuracy consistent with field conditions and common practice. Should a discrepancy in measurement exist which is greater than 10%, the item in question shall be re-measured by both the contractor and the Contracting Officer's Representative for verification.

7.2 MEASUREMENT FOR PAYMENT SHALL BE BASED ON THE FOLLOWING

SCHEDULE

MOBILIZATION shall not be measured for payment, and shall be paid for at the lump sum unit price bid.

SECTION 33 01 90 Page 11 PIPELINE CLEANING AND TELEVISION INSPECTION shall be paid for at the unit price bid per linear foot of each size pipe. Measurement of the actual number of feet cleaned shall be made from the center of the manholes. Payment for pipeline cleaning shall include compensation for obstruction removal as described above.

PUMPING AND BYPASSING OF SEWER FLOWS shall not be measured for payment, and shall be paid for at the lump sum unit price bid.

INSTALLATION OF LINER shall be paid for at the unit price bid per foot of liner installed for each size pipe.

POST LINING TV INSPECTION shall be paid for at the unit price bid per linear foot of each size pipe. Measurement of the actual number of feet inspected shall be made from the center of the manholes.

8.0 CLEANUP

After the liner installation has been completed and accepted, the contractor shall clean up the entire project area. The contractor shall dispose of all excess materials and debris not incorporated into the permanent installation in accordance with local laws and regulations.

9.0 GENERAL INFORMATION AND WARRANTY

The contractor shall warrant the liner installation for a period of one year. During the warranty period, any defects that affect the integrity or strength of the pipe shall be repaired at the contractor's expense in a manner mutually agreed upon by the owner and the contractor.
