Tasman Light Rail Corridor Study

HMH was selected by VTA’s predecessor, the Santa Clara County Transit District as Civil Segment Designer for the 4-mile portion of the Tasman Light Rail Project from the Santa Clara Convention Center to near Lockheed in Sunnyvale. Conceptual engineering drawings were prepared in AutoCAD using digital topographic data provided by the County and right-of-way and utility information compiled by HMH under a separate agreement. Submittal of the conceptual engineering documents, preliminary engineering drawings and estimates were made in 1992.

Final design services proceeded as funding was available from until the State Supreme Court overturned the 1992 Measure A sales tax. Design re-started in 1995 after approval of a new funding scenario using Federal Transit Authority (FTA) and state grants. HMH’s segment included four separate construction packages requiring  extensive interface with other designers. The two major packages were completed on time and within budget in early 1997.
