VTA Board Approves South Bay BART Expansion Contract – NBC Bay Area

BART took a step closer to reaching downtown San Jose and Santa Clara on Thursday when the Santa Clara Valley Transportation Authority’s board of directors unanimously approved the first major contract to build an extension BART in the heart of Silicon Valley.

VTA spokeswoman Bernice Alaniz said on Thursday that the first contract for the tunnel and track works, worth $235 million, had been awarded to Kiewit Shea Traylor, a joint venture. This is an evolving design-build contract.

VTA is building the BART extension to Santa Clara County. The first phase of the expansion brought trains to Milpitas and the Berryessa neighborhood of San Jose in late 2019.

The second phase is a six-mile-long extension from the Berryessa BART station to downtown San Jose and ultimately to Santa Clara.

The contract approved Thursday will be executed in stages, Alaniz said. It will include a survey of innovations, engineering and design, open book cost estimates and schedule of works.

The first stage of activities is expected to begin this month and last until approximately December 2023, paving the way for major construction that includes drilling the tunnel under downtown San Jose.

Three other contracts will be considered in the future for Systems, Stations and Santa Clara Station and Maintenance Yard.

VTA’s BSVII project is a four-station, six-mile extension that will bring BART service from Berryessa/North San Jose through downtown San Jose to the city of Santa Clara, includes three stations with underground platforms (28th Street/Little Portugal, Downtown San Jose and Diridon), a ground station (Santa Clara), a train maintenance and storage facility at Newhall Yard and additional facilities. Five of the six-mile alignments are planned to be constructed in a large-diameter single-hole tunnel, with the one-mile level rail remaining.
