South Bay Bus Maintenance Facility Expansion

Limited space at the San Diego Metropolitan Transit System’s South Bay Bus Maintenance Facility made it difficult to maneuver buses and perform required fueling, servicing and operational tasks.

As part of a design-build team for the San Diego Association of Governments (SANDAG) complex, STV provided architectural design and structural, mechanical, electrical and industrial engineering, as well as construction-phase support services and LEED® certification processing.

Now, the transformed facility boasts an expanded, reconfigured footprint, including a 49,000 square-foot high-bay maintenance building, a 12,000 square-foot operations and administration building and a two-bay bus wash building.  Natural daylight, photovoltaic electricity generation and a high-performance building envelope garnered a LEED® Silver certification. Additionally, the spacious facility better accommodates bus service, storage and parking for supervisor and staff vehicles. 

The sustainably designed effort earned the project Engineering Excellence Awards from the American Council of Engineering Companies at both the state and national levels.

Sustainable, expanded bus maintenance facility enhances transit operations for the Southern California region.
