The Contractor must provide proof of successful installation of CIPP rehabilitation<br />

projects on line sizes similar to this project in the state of California. In addition the<br />

Contractor & Manufacturer must have experience installing a minimum of 50,000 feet of<br />

cured-in-place product in wastewater collection systems. Installer’s project managers<br />

must have a minimum of 2 years experience of CIPP installation and must be on-site<br />

during the installation of the CIPP products. The person in charge of operating the<br />

remote control cutting operations to reinstate laterals shall have performed a minimum of<br />

fifty (50) successful remote cutting operations on 6-inch pipelines.<br />

MATERIALS<br />

All pipe shall be handled and stored as recommended by the manufacturer to maintain<br />

integrity. The Contractor shall submit the manufacturer’s recommendations to the<br />

Engineer for approval. All materials deemed damaged by the Engineer shall be removed<br />

from the project site and all expensed incurred shall be paid for by the Contractor.<br />

The tube shall be a material compatible with the resin system (designed for use in a<br />

wastewater environment) used to allow the tube to reach its full strength and size<br />

capacity. The tube shall be properly sized to fit tightly against the inner wall of the host<br />

pipe. The resin and pipe shall meet the structural and chemical resistance requirements in<br />

applicable sections of ASTM F1216/F1743.<br />

The finished liner shall meet the following structural requirements:<br />

Required Value<br />

Short Term Long Term<br />

Wall Thickness (TBD by Contractor)<br />

Flexural Strength 4,500 psi<br />

Flex. MOE 8<br />

250,000 psi 150,000 psi<br />

Tensile Strength 3,000 psi<br />

The tube shall be monitored for temperature at the beginning and end of the section being<br />

lined. The Inspector/Engineer shall access to temperature readings at all times during the<br />

curing process.<br />

TESTING<br />

The physical properties of the installed CIPP shall be confirmed by and independent<br />

third party laboratory recommended by the manufacturer and pre-approved by the City.<br />

Testing methods shall conform to ASTM Standards D790, D2122, and D638. One (1) set<br />

of tests will be required for each diameter of CIPP installed.<br />

8 Flexural Modulus of Elasticity<br />
