City of Sunny Isles Beach | Invitation to Bid No. 16-04-01 18 15. RESIN IMPREGNATED CURED IN PLACE PIPE (RICIPP) a. The RICIPP shall be fabricated to a size that when installed will fit the internal circumference of the conduit specified. Allowance shall be made for circumferential stretching during insertion. i. The finished RICIPP shall be fabricated from materials which when cured will be chemically resistant to withstand internal exposure to contaminants associated with stormwater. ii. A general purpose, unsaturated polyester or epoxy resin and catalyst system shall be furnished that provides cured physical strengths specified herein. iii. The minimum length shall be what deemed necessary to effectively span the distance- requiring repair. The Contractor shall verify the length in the field before impregnation and his estimate should be based on those lengths. iv. Physical Strength: The cured RICIPP shall conform to the minimum structural standards, as listed below Cured RICIPP Standard Results: Tensile Stress ASTM D-638 3,000 psi Flexural Stress ASTM U-790 4.500 psi Flexural Modulus of Elasticity ASTM N-790 290,000 psi b. RICIPP / INSTALLATION i. The Contractor shall provide for the flow of stormwater around or through the sections or sections of pipe designated for RICIPP. Any bypass shall be made by plugging the line at an existing upstream manhole and pumping the flow into a downstream manhole or adjacent system. The pump and bypass lines shall be of adequate capacity and size to handle the flow. The Contractor shall be responsible for continuity of the stormwater system during the execution of the work of this contract. In event that stormwater backup occurs, the Contractor shall be responsible for cleanup, repair and property damage costs and claims. ii. The method of installation of the RICIPP shall be in accordance with design criteria supplied by the manufacturer and approved by the City’s Project Manager. iii. The RICIPP shall be cured by a circulation of heated water. The water temperature and curing period shall be as recommended by the resin manufacturer. iv. The hardened RICIPP shall be cooled to a temperature below 100 degrees Fahrenheit before relieving the static head in the inversion process of the inflation pressure used by other methods. Care shall be taken in the release of the static head so that a vacuum will not be developed that could damage the installed RICIPP. v. The finished RICIPP shall be continuous over the length of repair and be as free as commercially practicable from visual defects such as foreign inclusions, dry spots, and pinholes.
