The City of Pittsburg, California is soliciting sealed bids for the Cabrillo Place Waterline water system reliability project in Contra Costa County, with a non-mandatory pre-bid meeting on November 17, 2026 at 11:00 a.m. at Woodland Hills Park near the project site and bids due December 2, 2026 at 2:00 p.m. at City Hall, 65 Civic Avenue. The contract is a prevailing wage public works project subject to California Labor Code requirements. Bidders must hold a valid California contractor's license in either Class A General Engineering or C-34 Pipeline Contractor classification and be registered with the California Department of Industrial Relations to perform public work.

The scope abandons, removes, and decommissions existing water facilities, including an asbestos-cement water main, and constructs approximately 1,680 linear feet of 12-inch PVC water main (DR-14, C900) within the public right-of-way along Alta Vista Circle, with tie-ins at Crestview Drive. Work includes butterfly valves, valve assemblies with anchor blocks, a combination air release valve assembly, a fire hydrant assembly, trench excavation and backfill, pavement and surface restoration, traffic control, and erosion and sediment control. Along Crestview Drive, valve installation proceeds in three phases, each limited to eight consecutive hours of water service interruption.

The estimated construction cost is $1.50 million. The project must be completed within 120 calendar days of the Notice to Proceed, with an anticipated start date of January 11, 2027. Bid security equals ten percent of the maximum bid amount, submitted as a cashier's check, certified check, or bid bond. The successful bidder must furnish performance and payment bonds, each for 100 percent of the contract price. Liquidated damages are $1,500 per day for each day of unexcused delay. The prime contractor must perform at least 50 percent of the work with its own forces, and subcontractors performing work exceeding one-half of one percent of the total bid price must also be registered with the Department of Industrial Relations.

The City will award the contract within 60 days after bid opening to the responsible bidder submitting the lowest responsive bid.
