Groundwater Recovery Facility Brine Line Improvements Project

The project involves comprehensive improvements to the Groundwater Recovery Facility Brine Line in Dana Point, California, under Contract No. 26-0038, managed by the South Coast Water District. The scope requires full labor, materials, and equipment for installing a 6-inch HDPE RO concentrate bypass pipeline, demolishing and reconstructing the upper portion of the existing concrete air gap structure with new concrete and piping, installing a 6-inch backflow preventer, removing and replacing the existing outfall vault with a larger one, and connecting the new bypass pipeline to the existing brine line and ocean outfall. Additional work includes cleaning scale buildup from the remaining air gap structure and the 18-inch ocean outfall pipeline. All work must comply with the District’s Standard Specifications, Greenbook Standard Specifications, and referenced standards such as AWWA C116 and ASTM B88, with materials required to be new and of specified quality, and substitutions subject to written approval. Packaging and preservation mandates include dual layers of Trenton primer and wax tape with 8-mil V-BIO polyethylene for buried metallic components, coating of bolts and nuts with No-Ox-Id 'A Special' grease, fusion-bonded epoxy on exposed fittings, and installation of 15 lb zinc anodes for cathodic protection. Underground utilities must be marked with 6-inch wide, 4-mil thick identification tape, and stenciled warning signs per SCWD STD DWG S-3 are required. Performance is governed by a fixed-price contract structure, with a target completion of 100 business days from the Notice to Proceed, including a five-day allowance for weather delays. The contract includes a $30,000 allowance for field orders and a $5,000 allowance for permit fee reimbursements, but no firm unit prices or total contract value are provided due to incomplete pricing data in the bid schedule. Bidders must hold a valid Class A contractor’s license, submit proof of $5 million per occurrence and $10 million aggregate liability insurance, and provide workers' compensation coverage. Contractors must identify a qualified construction superintendent through resume submission pre-award and certify non-debarment status, non-collusion, and compliance with California Air Resources Board regulations if operating off-road diesel equipment. The bid must be submitted electronically via PlanetBids by the August 21, 2026 deadline, with no hard copies accepted. Evaluation favors the lowest responsive and responsible bidder whose proposal best
