DBB Prima Zone 4 Phase A Main Gas Line Project

The DBB Prima Zone 4 Phase A Main Gas Line Project is a solicitation issued by OC Waste & Recycling for the design, permitting, and construction of a Landfill Gas Collection and Control System header installation at the Prima Deshecha Landfill. The scope of work includes trenching, the installation of 20, 24, and 36 inch HDPE SDR-17 piping, the placement of butterfly header valves, and the construction of traffic-rated concrete valve vaults. Additional requirements involve the excavation of approximately 200,000 cubic yards of breccia stockpile, the construction of gravel and asphalt roads, and the restoration of disturbed areas. The project is estimated at 9,120,900 dollars and must be completed within 210 calendar days from the notice to proceed, with liquidated damages set at 8,500 dollars per day for delays. The contract will be awarded to the lowest responsive and responsible bidder among a pre-qualified list of contractors holding a Class A General Engineering license. Bidders must provide a 10 percent bid security and commit to subcontracting at least 3 percent of the total contract value to certified OCLSB or DVBE firms. Compliance requirements include adhering to general prevailing wage rates, submitting certified payroll, and following the County's Safety and Loss Prevention Policy. Technical specifications mandate the use of 3 inch wide detectable foil marker tape and specific LFG identification on vault covers. The successful contractor is required to provide a baseline schedule within 30 days of the notice to proceed and submit weekly and monthly progress updates.
