HMH Engineers is performing a critical role on the SVBX C700 Design-Build team, performing utility coordination for design, preparing plans and specifications for municipal storm drain, sanitary sewer and water system relocations and topographic surveying.
As a key subconsultant to the design joint-venture, HMH is deeply involved in early utility relocation activities, assisting in coordinating relocations of Chevron petroleum lines, major PG&E gas transmission mains and numerous power, telecommunications and water facilities. We are also responsible for design of four critical early relocations of storm drain, sanitary sewer and water facilities, including a 66-inch and 42-inch welded steel transmission lines operated by Santa Clara Valley Water District.
The BART Berryessa Extension is a 10-mile, two-station extension, beginning in Fremont south of the future BART Warm Springs Station and proceeding in the former Union Pacific Railroad right-of-way through Milpitas, the location of the first station, and then to the Berryessa area north of San Jose, where the second station will be located. This is the first phase of the extension of the existing BART system to Santa Clara County. A second 6-mile phase that includes a 5.1 mile long subway tunnel through downtown San Jose, and ends at grade in Santa Clara near the Caltrain Station will commence as additional funding is secured.
