Enlarge the incoming and outgoing pipe openings, if required, to accommodate the maximum outside diameter size of the insertion equipment. Do not put undue stress on existing structures. In areas where existing manholes are not available, intermediate access pits may be excavated and utilized at no additional cost to the City. Intermediate pipe repair and restoration must be done in accordance with the Drawings at no additional cost to the City.

408.3.09 Installation

Install liner system according to ASTM F1216 Section 7 or ASTM F1743 Section 6, and the manufacturer’s recommendations.

(a) General⸺Where practicable, install liners in continuous runs through manholes where there are two or more continuous host pipe segments requiring lining. If manholes are lined through, remove crown of liner inside manhole flow channel. Provide temporary downstream dams in the pipeline to catch excess resin and construction debris. Contractor to dispose of excess resin per the resin manufacturer’s recommendations.

Do not allow the temperature of water discharged from processing liners to exceed 77 degrees Fahrenheit unless DEQ, upon the request of the City, approves alternate temperature limits not to exceed 125 degrees

Fahrenheit.

Furnish and keep one additional operational robotic cutter assembly train and key spare components on-site on a continuous basis as a “stand-by” unit in the event of primary equipment breakdowns.

01000 - 18 Special Provisions

(b) Pipe Liner End Seal⸺Install a continuous or properly trimmed end seal between the ends of the new pipe liner and the host pipe connection. Insert end seals at each structure opening approximately 3 inches max, 2 inches min from inside of structure wall to the inside edge of the end seal. For bands, butt-up trimmed end seal edges against each other at the crown of the pipe using a miter cut. Seals that have any gap between the ends will be rejected and repaired with an internal joint seal at no additional cost to the

Owner.

(c) Wet Out⸺Impregnate ("wet out") the tube with resin using distribution rollers and vacuum, or other approved method, to thoroughly saturate the tube prior to its dispatch. Transport and store the impregnated liner in a refrigerated truck or container until installation in such a manner that it will not be damaged, exposed to direct sunlight, or result in any public safety hazard.

Use a sufficient quantity of resin to fill air voids, and include additional allowance for polymerization and for any migration of resin into cracks and joints in the host pipe.

The City reserves the right to check, verify, or inspect all phases of production including manufacturing, shipping, wet-out, installation, cure, and/or finished product. Any departure from the submitted procedures may be cause for rejection.

(d) Insertion⸺Prior to insertion mark the exterior of the manufactured tube along its length at regular intervals not to exceed five (5) feet. Use the marks to measure elongation during insertion. The tube will be rejected and replacement required if the overall elongation of a tube reach exceeds five percent (5%), or as otherwise approved.

Maintain the pressure required to hold the flexible tube tight against the host pipe, per the manufacturer’s recommendations, until curing is complete. No other depressurization outside of the range required by the manufacturer for curing is permitted until the tube is fully cured and cooled. Capture and clean up all escaped resin.

(f) Curing⸺Use a suitable source of hot water or steam and a recirculation system capable of delivering the required amount of heat uniformly throughout the segment for a complete cure of the resin.

Fit the heat source with monitors to gauge the temperature of the incoming and outgoing heat supply. Install full-length temperature monitors prior to installing the liner. Additionally, place remote sensing devices

(such as thermocouples) between the impregnated tube and the invert and crown of the host pipe at each manhole to determine the temperatures during the resin cure process.

Modify the curing process if curing temperatures are above or below the resin manufacturer’s recommendations, as approved.

(g) Cool Down⸺Use a controlled cool-down process to cool the hardened pipe to a temperature in accordance with resin manufacturer's recommendation. Obtain the recommended cool temperature before relieving the static head or pressure in the lined pipe and returning normal flow back to the system. Take measures to release the pressure so that a vacuum will not develop and damage the newly installed CIPP system.

(h) Pollutant Control⸺For stormwater installations, process water, condensate, or any other material must not have a styrene concentration greater than 2.5 mg/L for discharge into downstream pipes that are carrying live sanitary flows. No water can be discharged until water chemistry compliance is met.

Contractor can utilize available downstream sewer, prior to live waste streams, for short term (48 hour) storage of water utilized in CIPP installation. Water, condensate, or any other material that exceeds this concentration must be captured or treated prior to discharge into the City’s sanitary sewer system. The use

01000 - 19 Special Provisions of styrene reducing agents will be allowed upon approval by the engineer. Styrene mitigation controls must be approved and fully operational prior to any lining work being completed.

Set up a containment barrier to capture the release of any inversion, cure, steam condensate, cool-down, or flushing water. All inversion, cure, cool down, flush water, and steam condensate that does not meet the requirements listed in the previous paragraph must be treated prior to discharge or contained and shipped off-site for disposal at an approved disposal facility.

Sample process water and submit to a third-party laboratory for analysis of VOCs. Submit all chain-of-custody forms to the Engineer. Analytical results demonstrating compliance with the maximum styrene concentrations must be provided within 24 hours following the initial installation and prior to the discharge of any additional process water.

408.3.10 Reconnection of Existing Service Laterals

Re-instate all service lateral connections after the liner system has been accepted except as directed. Locate and re-establish service laterals according to the manufacturer’s recommendations. Use equipment including, but not limited to, cutter heads, crawlers, CCTV cameras, hydraulic drums, counters, etc. that is suitable for the Work and in good working order. Use an approved internal cutting device and video camera to restore service connections to the full diameter of the service. Use qualified individuals with experience in successful internal lateral reinstatement to perform the work. Provide a permanent connection between lateral and main pipeline that is a water-tight, flush, smooth transition free of loose or abraded material.

Repair overcuts or undercuts, punctures, and ragged edges due to poor cutting of liner material at no additional cost.

Re-instate or correct, without any delay, all missed or faulty reconnections, as well as any sewage spill damage to property owners caused by missed reconnections.

408.3.11 Manhole Restoration and Structure Connections

After the cool-down period is complete, perform final trimming and sealing of the liner at access structures.

Provide watertight pipe and structure seals. Trim the finished ends of the liner to within one inch of access structure wall. Provide a smooth transition between the existing structure channel invert and the liner using a cementitious coating, or other approved material, to prevent settling of sediment or debris, and ponding of standing water. Seal all holes and voids in manhole and structure walls immediately surrounding the new liner with a chemical grout that is compatible with the resin mixture of the liner.

Reinstall manhole cones, slabs, grade rings, frames, covers, inverts, and reconstruct benches and channels after each pipe liner installation. Internal rehabilitation of manholes is not permitted until after the liner is installed and accepted.
