3.2 LINER INSTALLATION

3.2.1Pre Heating Prior to insertion of the liner into the host pipe the Contractor shall pre-heat the liner in the manner proscribed by the manufacturers installation instructions. The heated liner must be pliable enough to be pulled into the host pipe with as little resistance as possible.

3.2.2Pipe Liner Insertion The liner pipe shall be inserted into the sewer through existing manholes, without modification of the manholes. Insertion of the liner into the host pipe will be accomplished by pulling the liner into the host pipe by means of a steel cable strung through the host pipe from a winch located at the downstream manhole. The end of the liner shall be prepared for attachment to the cable in accordance with the manufacturers instructions. The connection between the pulling cable and the prepared end of the liner shall be a swivel device to prevent twisting of the liner as it is pulled through the host pipe. The heated liner coil shall be placed in such a manner as to prevent damage to the liner as it is pulled through the manhole and into the host pipe.

A member of the installation crew at the upstream end shall monitor the speed of the pull;

he must coordinate the speed of the pull with the winch operator at the downstream manhole via two-way radio. The crewmember coordinating the insertion of the liner shall ensure that the liner has the proper amount of slack, to prevent it from being either stretched or kinked.

3.2.3Stress Relief After the liner has been inserted into the host pipe, the Contractor shall relieve any stress imparted to the liner during the insertion in a manner proscribed in the manufacturer’s installation instructions.

3.2.4Processing The Contractor shall supply suitable heat source equipment. The equipment shall be capable of delivering steam through the lining section to uniformly raise the temperature of the PVC material to effect forming of the liner pipe.

Suitable monitors shall be installed to gauge steam temperatures and temperatures at the input and exhaust ends of the liner. Steam monitoring methods and forming period shall be recommended by the liner manufacturer.

After forming the liner shall be cooled using compressed air or a mixture of compressed air and water. Cooling shall be deemed complete when the temperature of the exhaust air or air water mixture has remained constantly below 110ºF for a minimum of 20 minutes.

3.2.5Pipe Liner Trimming After installation the ends of the PVC liner shall be cut off in the maintenance hole. The cuts shall be smooth and parallel with the maintenance hole wall. The finished liner shall not protrude into the maintenance hole over 2 inches.

If the maintenance hole has been lined through, the top half of the liner pipe may be cut off even with the top of the shelf, leaving the channel lined.

Sheet 6

3.2.6Sealing Manhole Connections If a watertight seal is required at the manhole it may be accomplished by troweling a high viscosity epoxy cement or resin around the exposed ends of the liner and the surface of the manhole. The surface of the epoxy cement shall be shaped to smoothly transition the exposed liner to the manhole wall. If specified by the Owner a hydrophilic gasket may be placed between the pipe liner and the host pipe prior to expansion of the liner. In either case the exposed liner in the manhole shall be smoothly transitioned into the wall of the manhole using the epoxy cement.

3.2.7Service Connections The exact number and location of service connections shall be determined from the CCTV inspection done in section 3.1.3.5 of this specification. It shall be the Contractor’s responsibility to accurately locate all existing service connections whether in service or not. The Contractor shall reconnect all potentially active service connections to the pipe liner, including those from unoccupied, abandoned or vacant lots. Capped service connections shall not be reconnected unless otherwise directed by the Owner. The Contractor shall be responsible for restoring/correcting, without delay, all missed service lateral connections. All service connections that are reinstated after lining shall be shown on the “As Built Drawings” with the exact distance from the upstream manhole.

All existing service connections shall be reinstated either by remotely controlled robotic device or by excavation.

Only experienced operators shall make robotic service connection reinstatements.

Should a dimple not form or cannot be clearly ascertained at a given service connection its position must be carefully re-verified using the inspection video from 3.1.3.5.

Service reconnections shall be smooth and circular in nature as observed by a pan and tilt TV camera. The hole shall be a maximum of 105% and a minimum of 90% of the service pipe diameter. The opening shall be smooth and conform to the inside shape and size of the original connection. Trial cuts should be repaired per the pipe liner manufacturer’s recommendations at no cost to the Owner.

3.3 POST INSTALLATION INSPECTION

Upon completion, and before acceptance of the work, the Contractor will inspect the rehabilitated pipeline using a CCTV camera with a pan and tilt head. The inspection shall be recorded on either VHS or DVD. The Operator will stop the camera at each lateral reinstatement and using the pan and tilt feature record and catalog each of the service connection cuts. The Contractor shall submit the post-installation video in either VHS or DVD format to the Owner for acceptance of the work.

3.4 INSPECTION AND TESTING

3.4.1Visual Inspection The pipe liner shall be continuous and joint-less. The pipe liner shall be free of all visual and material defects except those resulting from pre-lined host pipe conditions identified in the pre-lining video.

3.4.2Testing If required, the Contractor shall provide liner field samples to the Owner prior to installation for testing. The Owner will pay all expenses for the testing of liner samples

Sheet 7 to verify that the field samples meet the minimum specified values listed in Table 2.1.3.

The samples shall be tested per the recommendations of the pipe liner manufacturer The Contractor shall pay for the cost of re-tests made necessary by the failure of a sample to meet the minimum specified values listed in table 2.1.3. Field samples shall be collected in accordance with Section 7.3 of ASTM F 1867.

Normally separate leakage testing of the liner is not required, since the liner is under constant pressure during the cool down period. However, if separate leakage testing of the liner is required by the Owner in the specifications it shall be conducted at the time of installation after cool down and before the laterals are cut, in accordance with Section 7 of F 1867.

3.5 DEFECT REPAIR OR REPLACEMENT

Any defects, which in the judgment of the Owner and the pipe liner manufacturer that will affect the integrity or strength of the liner, shall be repaired or the pipe liner replaced at the Contractor’s expense per the pipe liner manufacturers recommendations.. All repairs or replacement of defective work shall be completed to the full satisfaction of the Owner.

3.6 WARRANTY

The Manufacturer shall warrant the product for a period of 10 years from the date of manufacture, against failure as a result of defects in materials or manufacturing, and that when properly installed the product will perform in accordance with the Manufacturer’s specifications, literature and data sheets.
