The contract pertains to the replacement of the fender system and modification of the concrete skirt on the west bay piers (W3, W4, W5, W6) of the San Francisco-Oakland Bay Bridge, with all work to be conducted from marine-based equipment over San Francisco Bay. The project involves demolition of existing fender components—treated wood, plastic lumber, and steel—as well as portions of the concrete skirt, followed by new construction including galvanic anodes, structural concrete with polymer fiber and RSC, precast concrete posts, stainless steel reinforcement, and miscellaneous metals. A new upper fender system will be installed featuring rubber fender units and Fiber Reinforced Polymer (FRP) panels, along with FRP walers and a new FRP drainage system, and stainless steel pipe handrailing. The work must comply with Caltrans Standard Specifications, PIANC performance data for fender systems, and federal regulations including the Clean Water Act and U.S. Army Corps of Engineers Nationwide Permit 15, with environmental protections for marine species and habitat required. All materials, particularly stainless steel and iron products, must be coated in the United States to meet Buy America provisions, and certifications of origin, mill test reports, and compliance documentation for all delivered materials are mandatory. Performance is expected to commence within 55 days of contract approval by the Attorney General, with a baseline Critical Path Method schedule submitted within 14 days of award. The estimated contract value is $110 million, with specific line items including mobilization, dispute resolution board meetings at $7,500 per session, and stainless steel reinforcing steel totaling 576,500 pounds. The Department of Transportation will conduct inspections and accept deliverables based on material test reports, performance verification data for rubber fenders, and submittal of the Stormwater Pollution Prevention Plan and Water Pollution Control Plan. Special requirements include a qualified safety representative with CSP, CIH, CHMM, or OHST certification, an asbestos survey before demolition, coordination with BCDC and USCG, and attendance at a mandatory prebid meeting. All proposals must be submitted via the Department’s Bidders Inquiries portal by the August 27, 2026 deadline, and the work will be performed exclusively at the Oakland, California location on the Bay Bridge’s west piers.
