Tara Hills Force Main Assessment Project

The Tara Hills Force Main Assessment Project (No. 21EG301) is a solicitation by the West County Wastewater District for construction services in Richmond and unincorporated Contra Costa County, California. The project scope focuses on assessing the force main through the installation of smart-pig launching and receiving assemblies at the Tara Hills Pump Station, the replacement of an 18-inch plug valve with a resilient seated gate valve at Rachel Road, and potholing at up to 20 sites. Comprehensive site work is required, including demolition, excavation, sheeting and shoring, bedding, backfill, surface restoration, and the installation of asphalt concrete paving, curbs, gutters, and sidewalks. The engineer's estimate for the project is 1,361,000.00 dollars, and any awarded bid exceeding 1 million dollars will be subject to the Project Stabilization Labor Agreement. Bids must be submitted via the OpenGov portal by 2:00 p.m. on September 25, 2026, and must include a detailed construction phasing schedule and proposal security of at least 10 percent of the proposal total. The award process emphasizes strict conformity to contract documents, with the District evaluating bidders based on technical organization, professional experience, and financial resources. Key contractual requirements include the provision of performance and payment bonds equal to 100 percent of the contract price, adherence to California prevailing wage laws, and a liquidated damages penalty of 500 dollars for each calendar day of delay. Work is deemed to start five calendar days after the Notice to Proceed is issued, provided a reasonable construction schedule has been submitted.
