4.4 POST-INSTALLATION INSPECTION AND TESTING REQUIREMENTS

1. After all liner installation and lateral connection work has been completed, the contractor shall inspect via CCTV all new CCCP within 3 weeks of installation completion. Inspection of pipelines shall be performed by NASSCO PACP certified, experienced personnel, trained in locating breaks, obstacles, and service connections using CCTV inspection techniques. For every segment of CCCP installed, the

2. Contractor shall generate a report that documents the installation including date, time, temperature, curing temperature, curing time, of applied material type and volume. The reports shall be submitted along with the post-installation CCTV inspection to the Engineer prior to acceptance of work and submittal of payment request.

3. There shall be no dry spots, lifts, ridges, splits, cracks, uncured mortar, delaminations or other defects in the CCCP. There shall be no visible infiltration through the liner or from behind the liner at manholes and service connections. Defects in the finished liner that cause backwater, reduce the pipe’s hydraulic capacity or structural stability or that create voids between the liner and pipe wall will be unacceptable.

Defective lining will be repaired to design specifications at no additional cost.

4. Thickness verification can be done with mass balance calculations where you calculate the amount of material that went in over the surface area to get an average depth.

5. Indicator tabs can be attached on the piping to verify the proper thickness is achieved. These are positioned to be just below the specified thickness and are left in place when sprayed over.

6. In addition, the engineer may request at his/her discretion the contractor to remove a test core(s) from the installed liner at specified location(s) at the Contractors’ expense. The Contractor shall mark the core samples with the date that the liner was installed and the date that the core was removed and the location taken. When requested by the engineer, the liner shall be cored at three different clock positions, and the average thickness measured shall be taking as the actual thickness of the liner. If a sample is not within 90% of the specified minimum thickness and or 90% of the 28-day compressive strength, the liner is considered unacceptable. Submit a proposed method of repair or replacement for review and approval by the engineer. Work required to remedy nonconforming work shall be at no additional cost.

7. Installed CCCP that does not meet the specified strength and / or thickness requirements, regardless of the deviation from these specified requirements, shall be corrected by the Contractor in a manner approved by the Engineer. Options for correcting deficient liner installations that will be considered by the Engineer include removal of the existing liner and re-lining the pipe or complete replacement of the storm drainage pipe.

PART 5 - MEASUREMENT

1. The quantity of Centrifugally Cast Pipe Liner to be paid for will be the actual number of linear feet of pipe liner, which has been installed and accepted. Measurement will be made horizontally along the centerline of the installed liner defined as the distance between the upstream and downstream structures using applicable structure inside walls as the beginning and ending point. Measurement from center of structure to center of structure will not be permitted. Measurement will not be made across drainage structures.

2. Invert Mortar Repair will be measured and paid in cubic yards, which has been incorporated into the completed and accepted work in accordance with the special provisions.

PART 6 - WARRANTY

1. Furnish one-year manufacturer's warranty for liner.

PART 4 - CONSTRUCTION METHODS

4.1 SITE PREPARATION

1. The Contractor shall verify site conditions prior to commencing any construction activities. Site conditions include, but are not limited to, inlet and access port accessibility, accessibility to remote locations and encroachment onto private or publicly owned property. Selection of inspection equipment shall be based on the conditions of the storm drainage piping, structures, and inlets at the time the work commences. All dimensions shall be field verified by the Contractor.

2. The Contractor shall clean existing pipes of debris, sedimentation, and mineral deposits with high-velocity cleaner, bucket scraper, root saws, rolling or balling units, or other appropriate means.

3. The Contractor shall conduct a NASSCO PACP compliant color digital television inspection of each length of pipe prior to ordering liner. The purpose of this inspection is to confirm that existing conditions are suitable for the installation of the proposed lining process, to document the location of all service lateral connections and to confirm point repair locations. Digital recordings shall be prepared and retained by the Contractor and submitted with the post-lining inspection recordings prior to request for payment. Where this television inspection reveals conditions that are not suitable for lining, the digital recordings shall be immediately provided to the Engineer for review.

4. The Contractor shall protect the storm drainage system and adjacent properties from damage that might result from construction. Any damage caused by the Contractor’s operations shall be repaired to the complete satisfaction of the Engineer at no additional cost.

5. Protruding lateral connections, if encountered, shall be cut or ground with a robotic cutter flush with the pipe to be lined prior to liner installation. All lateral connections for reconnection after CCCP installation shall be documented. The cutting operation shall be monitored by CCTV equipment to verify proper execution of work.

Equipment specifically designed for cutting roots from storm drainage pipes (such as a chain cutter) shall not be allowed for this purpose.

6. If, in the opinion of the CCCP manufacturer, the rate of infiltration in the storm drainage pipe presents washout risk of the applied material, then the Contractor shall perform measures as required to minimize infiltration prior to lining. Any infiltration gusher identified shall be brought to the attention of the Engineer. The Contractor shall submit for approval to the Engineer the measures to prevent any adverse issues to the installation of the final product. The submittals shall be reviewed and approved prior to installation.

4.2 DELIVERY, HANDLING AND INSTALLATION

1. Normal precautions for “nuisance dust” shall be observed. Consult manufacturer’s Material Safety Data Sheet for details. The Contractor shall install liner in strict accordance with applicable OSHA standards.

The bypass pump(s) shall be setup and ready for immediate operation. Pumps shall be automatically controlled. The Contractor shall properly maintain the bypass pumping system. A responsible operator shall be on site at all times during bypass pumping operations. Drainage flows from existing storm drainage pipes shall not be allowed to enter the rehabilitated facilities until those facilities have been cleaned and CCCP completely installed including curing.

3. Contractor shall reopen all existing lateral connections in each length of pipe following liner installation.

Lateral connections shall be determined from the pre-installation CCTV inspection. The lateral connections shall be reopened from inside the pipe by means of a television camera controlled cutting device appropriate for the liner material and the pipe. All pipe connections shall be completely opened, clean and neatly cut, shall be flush with the lateral pipe and the cut shall be wire polished. The bottom of the opening shall be flush with the bottom of the lateral pipe so that there is not a lip. All liner penetrations shall be watertight. The Contractor shall be fully responsible for all backups and damage caused by unopened or not fully opening lateral connections, including paying all costs associated with repairing damage as required by the Engineer, Owner and/or property owner.

4. Contractor shall, with approval from Fulton County, discharge all water used for cooling, heating, and curing to the existing sanitary sewer system. Contractor may utilize a vacuum truck to remove the water from the site and discharge directly to a wastewater treatment plant. No water used for the installation of the CCCP shall be discharged into the downstream storm drainage system.

4.3 HOT AND COLD WEATHER APPLICATIONS

1. Apply liner material during suitable ambient temperatures per manufacturer’s recommendations. Liner shall be protected in hot (above 80°F and rising) and cold temperatures (below 45°F and falling).
