Bid #S26033. Santa Clara Valley Transportation Authority, San Jose, California. VTA is soliciting proposals from qualified and experienced firms to perform a comprehensive assessment of the existing Vasona Corridor signal system and to provide full. Due Jun 23 (9 days left).
VTA is soliciting proposals from qualified and experienced firms to perform a comprehensive assessment of the existing Vasona Corridor signal system and to provide full engineering design services for signal system upgrades. The existing signal system for light rail within the Vasona Corridor currently utilizes the AFTAC II train detection system and Electrocode DC systems with fixed blocks, managed by the Vital Harmon Logic Controller (VHLC) microprocessor system. The VHLC system also coordinates the US&S gate mechanisms for protecting the highway-rail grade crossings on the corridor, shared with Union Pacific Railroad (UPRR) freight trains. This design scope should account for the independent, upcoming signals changes on the rest of the VTA system. In completed designs by others, VTA is upgrading UPRR train predictor systems from obsolete HXP-3R to Alstom XP4 systems on Vasona corridor, and overhauling the VHLC microprocessor system with ElectroLogixs on Guadalupe Southline corridor. VTA is also exploring a new design for its future fleet of cars, which anticipates new onboard technologies for positive train control, and a different car length and braking distance. Assumptions on future car specifications should be documented throughout this assessment and design process. The selected firm will be responsible for preparing complete Plans, Specifications, and Estimates (“PS&E”), and for providing support services during the bidding and construction phases of the Project.

Santa Clara Valley Transportation Authority in San Jose, California is using this solicitation to procure engineering work. Public buyers typically advertise this kind of work as an Invitation for Bids (IFB), Request for Proposals (RFP), or Request for Qualifications (RFQ), depending on whether the selection is price-driven, qualifications-driven, or both. Bidders responding to a engineering solicitation in California are generally expected to provide proof of liability insurance and workers' compensation coverage, hold any state license or trade certification required for the scope of work, and post performance and payment bonds for contracts above the agency's threshold.
Federal-aid funding flowing through programs such as the Federal Highway Administration, FEMA, or the Infrastructure Investment and Jobs Act brings additional compliance requirements on solicitations like this one, including Davis-Bacon prevailing wage, Buy America provisions where applicable, and Disadvantaged Business Enterprise (DBE) participation goals set by the issuing agency. PublicBidSearch indexes this solicitation alongside other open bids in California so contractors and vendors can compare active opportunities by category, agency, or location without monitoring each procurement portal individually.
To submit a bid for this IFB, review the full solicitation documents for Santa Clara Valley Transportation Authority's exact scope of work, submission format, and any mandatory pre-bid meeting or site visit. Responses must be received before the June 23, 2026 deadline — public agencies routinely reject late submissions regardless of cause. Confirm how the agency accepts responses — through an electronic procurement portal, as a sealed hard-copy bid, or by email — because the required method varies by agency and a non-conforming submission can be disqualified. Vendors that have not previously contracted with Santa Clara Valley Transportation Authority should confirm whether registration on the agency's vendor system is required to be eligible for award.
