Water System Reliability (Cabrillo Place Waterline)

The City of Pittsburg, California, is soliciting bids for the Water System Reliability project, specifically focusing on the Cabrillo Place Waterline located along Alta Vista Circle. The scope of work includes the decommissioning and removal of existing asbestos-cement water mains, as well as the installation of butterfly valves, valve assemblies with anchor blocks, a combination air release valve assembly, and a fire hydrant assembly. The project also encompasses trench excavation, backfill, pavement and surface restoration, traffic control, and erosion and sediment control. A critical performance requirement is that water main valve installation on Crestview Drive must be completed in three phases, with each water service interruption limited to eight consecutive hours. The entire project must be completed within 120 calendar days from the Notice to Proceed. The contract will be awarded to the responsible bidder who submits the lowest responsive bid. Bidders must provide bid security equal to 10 percent of the maximum bid amount and, upon award, provide performance and payment bonds for 100 percent of the contract price. The project is subject to California prevailing wage requirements and Buy America standards for federal-aid construction. Contractors are expected to adhere to ADA compliance for pedestrian and bicycle routes and are encouraged to award 20 percent of the contract value to local small businesses. Final acceptance by the City requires the completion of all punch list work, submission of as-built drawings and O&M manuals, and successful testing of all systems.
