Santa Clara Valley Transportation Authority (VTA) in the US state of California has awarded a Bay Area Rapid Transit (BART) Silicon Valley Phase II Extension Project contract to the joint venture (JV) of Mott McDonald and PGH Wong Engineering (MMW).
The $125m contract encompasses general engineering services for the Phase II extension project.
MMW won the contract through a competitive bidding process, which began in May.
Under the contract, MMW will carry out design and engineering work on the five-mile tunnel, four station areas, two ventilation structures and associated system-wide work.
Overall, the JV will take the BART Phase II Project to a 30% engineering level, helping to determine costs and schedule estimates, as well as support VTA’s management, financial and implementation plans.
The project work will enable VTA to participate in the Federal Transit Administration (FTA) Expedited Project Delivery (EPD) Pilot Program.
VTA is seeking federal funding to implement the project, which is estimated to cost nearly $4.7bn. It submitted the application to enter the EPD Pilot Program for Phase II in November.
Implemented with a phased construction approach, the planned 16-mile long BART Silicon Valley Extension will bolster the existing rapid transit system in Silicon Valley.
Phase I of the extension includes a ten-mile stretch with two stations. Currently under construction, the section is expected to open this year.
Phase II of the extension involves the remaining six-mile four-station section, which extends south into the cities of San José and Santa Clara.
Once completed, BART will operate and maintain the extension.
