SVRT/BART Fremont to SJ

SVRT/BART Fremont to San Jose, Line Segment,
Downtown Tunnel Segment and Stations

Project Dates: 2004 – 2012

Client: VTA-Silicon Valley Rapid Transit, BART

Cost: $750 Million (Phase I)

Project Description: Santa Clara Valley Transportation Authority (VTA) is currently constructing the Silicon Valley Rapid Transit (SVRT) Project. This is a 16.3-mile long extension of the Bay Area Rapid Transit (BART) heavy rail transit system from its planned terminus at the Warms Springs Extension in Fremont, to San Jose. The ultimate project will included 33 structures, underground stations, track-way with retained fill structures (MSE walls), six parking structures, two above ground stations, three pedestrian overcrossing structures, four roadway bridges, parking lots, transit centers, and auxiliary buildings.

Services: PARIKH Consultants, Inc. provided geotechnical engineering services for the SVRT/BART extension along the existing Union Pacific Railroad corridor. The firm was responsible for the preparation of field investigation plans, execution of field and Laboratory testing, conducting engineering analyses, and preparing preliminary geotechnical recommendations for the track way and structures across seven zones. Work included over 200-field exploration, CPT, Seismic CPT tests, and groundwater monitoring wells. The downtown segment included data acquisition and preparation of laboratory test results and log of test borings.

Phase I of the project is from Warmsprings station to Berryessa Station. PARIKH is part of the Design-Build team that provided full geotechnical engineering services. Project included at-grade trackway, tunnel section at Dixon Landing, below-ground station at Milpitas, and an above-grade guideway and station at Berryessa Avenue Terminus. Project challenges included an aggressive schedule, cost-effective design alternatives, below ground structures, Soil Structure Interaction (SSI) analysis, innovative foundation options, and aerial guideways and embankments. PARIKH is providing geotechnical studies for the two station campuses, parking lots, city streets, and design-build parking garages.
