B. Bid Due Date/Time REVISION

1. Work Order Offers are Due: no later than 1:30 p.m. local time on Wednesday, March 26, 2025.

C. Questions/Answers

1. Question: The plans are missing Sheet C 12 Seq. 15 of 25. This is the page for Task 9. Can you please provide?

Answer: The sheet is added to the plans by this addendum (Attachment 3)

2. Question: The Supplemental Technical Specification Section 33 01 30.72 for CIPP calls for 3rd party lab testing samples. How many samples you require?

Answer: The specification is modified to specify the sampling frequency (Attachment 4).

3. Question: The Supplemental Technical Specification Section 33 01 30.72 for CIPP - Section 2.2 A.1 Materials - for water or steam cure material requires approved epoxy, epoxy polyester, or epoxy vinyl ester resin. Epoxy resins are used for pressure pipe applications that require NSF61 drink water standards, and this material is very expensive and not necessary for gravity sewer applications. Question: Will the Owner approve a standard polyester resin which is the typical resin used for gravity sewers?

The initial structural properties as noted in the provided table on pdf page 115 can be met with polyester resin.

Answer: Yes, the specification is modified to allow polyester resin (Attachment 4).

– EXECUTION

3.1 EXAMINATION

A. Proceeding with Work specified in this Section shall be interpreted to mean that all conditions, including site conditions, were determined to be acceptable prior to start of Work.

3.2 PREPARATION

A. Complete all pre-approved obstruction removals, pipe cleaning, and point repairs per STS 33

01 30.41. Complete the pre-rehab CCTV inspection including submittal and approval by ENGINEER and OWNER per STS 33 01 30.11. All sewer service connections shall be identified and located prior to liner installation. All sanitary sewer flow control shall be approved by ENGINEER and OWNER and in-place and operational prior to liner installation.

3.3 INSTALLATION:

A. All CIPP installations shall be per manufacture’s written recommendations. Precautions shall be taken to protect the new liner and the existing pipe and manholes from any damage that might result during the insertion process.

B. Water or Steam Cured-In-Place Pipe (CIPP) Liner

1. The outside diameter of the tube being installed shall be sized to allow for expansion so that the CIPP can fit tightly against the existing pipe. CIPP shall be installed in accordance with ASTM F 1216 or ASTM F 1743 and the CONTRACTOR'S recommendations as approved by the ENGINEER. Immediately prior to installation, the CIPP liner tube shall be saturated with resin (on or off the work site) and stored/transported at a cool temperature as recommended by the resin manufacturer.

2. Curing: After tube placement is completed, the CONTRACTOR shall provide a suitable heat source and distribution equipment to distribute or recirculate hot water or steam throughout the installed CIPP liner tube. Temperature shall be maintained during the curing period as recommended by the resin manufacturer and approved by the ENGINEER. After the tube is cured, a cool-down period shall be used prior to opening the downstream end, reinstate service lateral connections, and returning normal flow back into the system.

33 01 30.72 -7

Heat curing of the resin shall occur within the manufacturer's approved recommended period (pot life). The water in the CIPP shall be cooled to below 100°F (38°C) before discharge.

C. Ultra-Violet Glass Reinforced Cured-In-Place Pipe (UV CIPP) Liner

1. Liner installation shall be in accordance with ASTM F2019, Section 6.

2. Resin Impregnation: The liner tube shall be impregnated with resin in accordance with ASTM F2019, Section 6.3.1, with the following requirements:

The fabric tube shall be totally impregnated with resin (wet out) in the manufacturers plant under quality-controlled conditions. The impregnation equipment shall contain devices to secure the proper distribution of the resin (resin bath). Certification documentation concerning date, type of resin, resin volume, mixing ratio, liner thickness, temperature, type of glass fiber, manufacturing date shall be stamped and/or marked on the finished uncured fiberglass liner by the UV CIPP manufacturer

3. Tube Insertion: A plastic slip-sheet shall be installed in the bottom half of the pipe prior to liner insertion. The slip-sheet is used to protect the outer film from damage during insertion from offset joints, broken pipe, or slightly protruding taps. In addition, it will increase flow characteristics and reduce friction during the pull-in process. Once the slip-sheet is in place, the shipping crate is opened, and the pre-impregnated spiral wound fiberglass liner is prepared for insertion into the host pipe following manufacturer procedures. Care should be taken to protect the ends of the liner from contaminates within the sewer such as moisture. A double capstan, constant tension winch shall be used to pull the spiral wound fiberglass liner into position. The double capstan, constant tension winch must be capable of documenting the amount of tension used to pull the liner into the pipe. Maximum pulling forces established by the manufacturer will not be exceeded. The tube shall be pulled-in through an existing manhole or approved access point and fully extend to the next designated manhole or termination point. During the pull-in process, the liner is manually fed into the pipe by the install technician. Care should be taken during this process not to tear or damage the outer film, thus exposing the liner to contaminates within the pipe. Lubricants used for tube insertion shall be subject to the approval of the OWNER.

4. Curing: Once the liner has been inserted into the host pipe, an end plug or packer is used to cap one end of the liner to prepare for initial pressurizing. The packer should be secured with a strap to prevent it from being expelled due to pressure. The other end of the liner is held closed manually by the technician.

The liner is then pressurized using forced air to the initial pressure of one 1 psi.

The spiral wound fiberglass liner shall be cured with a UV light source (i.e. light train). The UV light train should be assembled according to the manufacturer's specifications for the liner diameter. Once initial air pressure is achieved, the technician shall insert the light train into the open end of the liner. When inserting the light train, care should be taken not to damage the inner film material or the light train. After the light train is inside the liner, a packer is secure, fill liner inflation may begin. The air pressure will be raised at one 1 psi increments and held for approximately ten 10 minutes before increasing the

33 01 30.72 -8 pressure to the next level. Typical optimum inner air pressure is between 6 psi and 8 psi. However, the CONTRACTOR shall follow the manufacturer's recommendation for inner liner pressure according to the actual liner design used for the specific installation. Once optimum inner air pressure is achieved, a visual "pre-curing inspection of the liner will be done using CCTV. Once the "pre-cure" inspection is completed and the OWNER'S representative gives approval, the actual curing of the liner can begin. Curing of the spiral wound fiberglass liner is achieved through exposure to UV lights. The lights are energized in sequence according to the manufacturer specifications. The UV light train shall be capable of curing the fiberglass liner at a curing rate of up to 10-lf (linear feet) per minute

5. Record of Curing: For the liner to achieve the required water tightness and specified mechanical properties, the following parameters must be controlled during the entire curing process, giving the OWNER a record of the curing process over every segment of the entire length of the liner. This demonstrates that the entire liner is cured properly and completely. The recording will include:

a. Curing speed.

b. Light source working and wattage.

c. Inner air pressure.

d. Exothermic (curing) temperatures.

e. Date and time.

f. Length of liner.

6. Record of the curing parameters will be accomplished using a computer and database that are tamper proof. During the curing process, infrared sensors will be used to record exothermic curing temperature data. The parameters for curing speed, inner air pressure and wattage are defined in the Quality Tracker UV curing protocol issued by the manufacturer. The optimal curing speed, or travel speed of the energized UV light train, is determined for each length of liner based on liner diameter, liner thickness, and exothermic reaction temperature. A video will be recorded using CCTV during the curing process. The liner is cured once the energized light train has traveled the entire length of the liner.

7. Post Curing: The outer film that has been manufactured to control resin loss, liner thickness, and contamination of the resin by water or other contaminants as well as a styrene barrier, shall remain in-place after UV curing of the liner has been completed. The inner film will be removed no sooner than 30 minutes after the curing of the liner is complete. Ensure the curing method provides uniform temperature application for effective curing throughout the liner

3.4 END SEALS

A. The finished linear shall be cut smooth and parallel with the manhole wall. The interface between the host pipe and the pipe liner shall be sealed 360 degrees.

33 01 30.72 -9

3.5 REINSTATE SERVICE LATERAL CONNECTION

A. All live services shall be immediately reinstated after the liner installation (pipeline rehabilitation) is complete. Inactive service lines to a vacant lot, vacant building, or to an occupied residence with more than one service line serving the property, shall be defined as a “live” service, and shall be reinstated. It is the CONTRACTOR’S responsibility to locate all live services prior to rehabilitation activities. Each service lateral connection shall be noted by its size, position from a reference manhole, and orientation with respect to the circumference of the pipe. Reinstatement shall be accomplished from the interior of the sewer line by means of a television camera and a remote-controlled cutting device. Holes cut through the rehabilitation liner shall be neat and smooth and shall match the bottom of the reinstated service line. The service opening shall be reinstated to a minimum of 95 percent and a maximum of 100 percent of the service lateral pipe area. Service lateral openings that expand in diameter between the exterior and interior of the pipe wall shall be reinstated by cutting a hole in the liner that is 95 percent to 100 percent of the expanded diameter. The new edge shall be crack free with no loose or abraded material. Reinstated services that do not conform to this section shall be repaired and CCTV video confirmation.

The repair method shall be compatible with the lining system per the lining system manufacturer and as approved by OWNER. No extra payment shall be made for the repair and CCTV video confirmation.

B. The CONTRACTOR shall have a fully operational backup device for reinstating service laterals. If for any reason the remote cutting device fails during the reinstatement of a service lateral, the standby device shall be immediately deployed to complete the work. The backup device shall be fully functional without requiring removal of parts from the primary device. The backup equipment shall be onsite throughout the reinstatement process and will be periodically tested upon request of the ENGINEER. If for any reason the CONTRACTOR is unable to remotely reinstate a service lateral connection, the CONTRACTOR shall reinstate the service lateral connection by open cut.

C. Service lateral reinstatement by open cut includes locating all interfering utilities, existing surface removal, excavation, dewatering, reinstatement of service lateral connection, backfilling, surface restoration, temporary flow bypassing, and sewer dewatering.

Reinstatement of service lateral connection by open cut includes the removal and replacement of the first five (5) feet of service lateral, cutting of liner for the service opening, and installing a pre-fabricated fitting (Inserta-Tee® or equivalent) with the manufacturer’s specifications so that a complete water-tight seal is achieved. The new service line shall be connected to the existing service line with a flexible coupling and stainless-steel bands, as approved by OWNER. The service lateral connection at the pipeline shall be encased in lean fill, a minimum of six inches (6") below and twelve inches (12") above and on the sides of the pipe. The lean fill construction shall be inspected and approved by the OWNER prior to completing the trench backfilling.

2. A defect is identified that impedes any future inspection or cleaning of the pipe (Level 2 Defect);

3. A defect is identified that compromises the structural integrity of the liner system. (Level 2 Defect)

4. A defect is identified that penetrates through the liner system not including an accepted service re-instatement;

Level 1 Defect = Penetration is between the 10 and 2 position and the penetration is less than 3 inches in diameter

Level 2 Defect = Penetration is between the 3 and 9 position OR the penetration is greater than 3 inches in diameter.

5. Service re-instatement does not meet requirements of this specification. (level 1 Defect)

D. A defect that is identified due to a host pipe deficiency including a partially or fully degraded section shall be repaired by the CONTRACTOR but paid for by the OWNER if:

1. The location of the host pipe deficiency was identified in writing to the ENGINEER under STS 33 01 30.41.

2. A CCTV inspection video of the pipe is provided that was performed not more than 12 hours before the pipe liner was installed during no flow or low flow (less than 25% full) conditions showing no existing loose debris.

3. OWNER and ENGINEER recognize that due to the severe degradation of some host pipes, defects caused by host pipe deficiency versus CONTRACTOR error/negligence will be decided on a case by case basis.

3.7 POST-REHABILITATION POINT REPAIR/LINER PATCH

A. This subsection specifies the trenchless liner patch installation or point repair of rehabilitated pipelines to repair a liner defect.

1. TRENCHLESS LINER PATCH: A trenchless liner patch shall be up to 4 linear feet long and be approved by the liner manufacturer. The removal, extraction, and disposal of debris/obstruction in between the host pipe and pipe liner using a remote device shall be completed prior to patch installation.
