Silicon Valley Rapid Transit Project/BART
Alternative transit connecting San José to the San Francisco Bay area
Santa Clara Valley Transportation Authority | United States | 2008-2017
16.3 mile extension
Tunneling in a dense urban environment
USD 6 billion in project costs
Challenges
- It was necessary to extend the BART system into downtown San José to provide a transit alternative to the highly congested I-680 and I-880 commuter corridors.
- San José was then able to become connected with the rest of the San Francisco Bay area.
- The extension meant that tunneling was needed through a dense urban environment in soft fluvial soils.
Solutions
- Hatch (in JV) was responsible for designing the tunnel segment: the alignment, tunnel lining and cross passage (CP) design, settlement analysis and mitigation, coordination with BART facilities standards, station interfaces, cost estimating, construction sequencing, and specification of owner-procured tunnel boring machine (TBM) and lining systems.
- We also were responsible for project management support services, project cost control, maintaining a trend log and estimating changes, performing independent cost estimates of proposed changes, and schedule controls for the entire Silicon Valley Rapid Transit project.
- Extensive geotechnical investigations included 101 borings, 179 cone-penetrometer tests, and six pumping tests.
Highlights
- The BART extension will provide alternate transit options.
- It will reduce traffic congestion and eliminate approximately 16,000 tons of greenhouse gases in a year.
- It will also provide support for development along the length of the corridor.
- Overall cost and schedule-control management were seamlessly provided for a highly complex transit project.
