Santa Clara Valley Transportation Authority's board last week authorized the first construction contract for the Bay Area Rapid Transit Silicon Valley Phase II project, which when completed will connect the San Francisco transit system to San Jose and Santa Clara, California.
The first contract package for the tunnel, trackwork and design build was awarded to Kiewit Shea Traylor Joint Venture for $235 million. The work's first stage will involve innovations, engineering and design; cost estimates; and work scheduling. It will continue through December 2023 and prepare for major construction in the second stage, which will include boring the tunnel under downtown San Jose.
Kiewit Shea Traylor is a joint venture between Kiewit Infrastructure West Co., J.F. Shea Construction and Traylor Bros. Inc.
Three other future contracts being considered will be for the systems, stations and the Santa Clara Station and Maintenance Yard, authority officials said in a press release.
The project is a 6-mile, four-station extension to bring BART service from Berryessa/North San Jose through downtown San Jose to Santa Clara, including three stations with underground platforms and one ground-level station. A train maintenance and storage facility at Newhall Yard and other facilities are also planned. Five miles of the total 6-mile alignment will be constructed in a large diameter single-bore tunnel.
