San Pablo Dam Road 24" ACP -CIPP Trunk Line Rehabilitation

The West County Wastewater District is soliciting informal bids under solicitation 26-NIIB-052 for the rehabilitation of a 24-inch ACP Class 5000 pipeline on San Pablo Dam Road. Following a CCTV assessment that identified failures in the existing liner and poor overall pipeline condition, the project requires the installation of approximately 420 linear feet of 24-inch CIPP liner between manholes MHM17105 and MHM17106. To minimize impact on traffic and sewage flows, construction must be performed during nighttime hours. The project must be completed within 30 to 45 calendar days of the Notice to Proceed, with final acceptance contingent upon WCW inspection and post-work CCTV assessment. The contract will be awarded to the lowest responsible bidder who meets specific qualification requirements, including holding a valid General A, C-34, or C-42 license and maintaining registration with the Department of Industrial Relations. Bidders must submit a comprehensive package via the OpenGov portal by November 13, 2026, including a bid form, a 5 percent bid security, a statement of qualifications, a non-collusion declaration, and a CARB certification for off-road diesel-fueled fleets. Required personnel include a Project Manager, an On-Site Superintendent, and a Safety Representative. For projects exceeding 25,000 dollars, notarized payment and performance bonds are mandatory.
