Replace bridge fender system and skirt modification.

The contract pertains to the replacement of the bridge fender system and skirt modification on the west span of the San Francisco-Oakland Bay Bridge, specifically between 2.0 miles west of Yerba Buena Tunnel and the tunnel itself, within the City and County of San Francisco. The work involves fabrication, assembly, and installation of an upper fender system comprising rubber fender units of leg type, Fiber Reinforced Polymer (FRP) panels with stainless steel plates and UHMW polyethylene pads, anchors, and hardware to connect these components to pier concrete skirts. The project is governed by Caltrans Standard Specifications with supplemental Special Provisions that align with the main section headings and establish revised requirements for materials, construction methods, and testing. Key deliverables include shop drawings, certificates of compliance, safety data sheets, manufacturer instructions, and performance verification test reports for the rubber fender units, all subject to strict technical compliance. The contract mandates adherence to stringent quality standards, including design verification and witness panel testing for FRP walers, splice plates, and panels, with defined mechanical properties such as ultimate flexural strength, shear strength, tensile and compression modulus, and pin bearing resistance. Rubber fender units must meet minimum deflection and energy absorption thresholds under load testing. Welding must comply with AWS D1.6, and all concrete must conform to specific Caltrans sections, while hot mix asphalt follows Section 39-2. The contract includes Buy America/Build America compliance requirements, with penalties for failure to submit required documentation. Contractors must submit certified payroll records via LCPtracker Pro, adhere to DVBE and small business subcontracting preferences, and provide a qualified safety representative with Cal/OSHA credentials, three years of heavy construction experience, and valid first aid certification.
