Manson Construction Launches Subcontracting Bid for Vallejo Ferry Terminal Project
en.Wedoany.com Reported - On November 10, Manson Construction issued a notice soliciting subcontractors and suppliers to submit bids for the Vallejo Ferry Terminal renovation project (RFP 25-053) of the San Francisco Bay Area Water Emergency Transportation Authority (WETA), seeking quotes from Disadvantaged Business Enterprises (DBEs) and Small Business Enterprises (SBEs). The project involves in-water construction and demolition, new construction and renovation of existing structures, utility extension and relocation, and receipt and final installation of WETA's standard floating dock. The overall bid deadline is November 23 at 4:00 p.m., and subcontractor and supplier quotes must be submitted by November 20 at 4:00 p.m.
The work is located at the existing ferry terminal at 289 Mare Island Way in Vallejo, California. The renovation focuses on demolishing and replacing the existing terminal's passenger floating platform, boarding gangway, and associated pile foundations, extending the new terminal approximately 200 feet (about 61 meters) toward the Napa River. The new floating platform is oriented along the river's current direction and can accommodate two ferries berthing simultaneously with passengers boarding and disembarking. According to WETA's project environmental review documents, relocating the terminal is expected to extend the maintenance dredging frequency from once every 4 years to approximately once every 20 years, reducing long-term maintenance operations.
In-water construction includes demolishing existing steel piles, fixed trestle, boarding gangway, and passenger floating platform, then installing new pile foundations, floating platform, and associated berthing facilities. The preliminary design involves installing approximately 17 to 18 new piles, with new terminal structures and related facilities totaling approximately 9,515 square feet, including approximately 3,735 square feet for the fixed trestle, boarding gangway, and protective structures, and approximately 5,650 square feet for the new floating platform, plus fender facilities. The project also involves upland site improvements, utility line extension and relocation, and relocation of electrical, communication, and security systems.
The subcontracting and supply scope solicited by Manson Construction covers steel pile and composite pile supply, rebar fabrication and installation, ready-mixed concrete supply, cast-in-place concrete pumping and placement, metal components, aluminum walkways, rubber fenders, diving operations, mechanical and piping facilities, electrical and communication systems, security equipment, environmental monitoring, material testing, and transportation. The project requires relevant subcontractors to provide performance bonds and payment bonds, and eligible firms may apply for assistance with project scope, insurance, and bonding.
Ferry service must be maintained during construction. WETA's previous environmental review proposed maintaining operations through a temporary passenger floating platform during demolition of the existing terminal and installation of new facilities. In-water construction must comply with a restricted work window from August 1 to November 30 each year, covering pile demolition, installation, and floating platform placement. The project's environmental permits also require the contractor to control the impact of in-water operations on the river channel and aquatic life.
