South Bay Bus Maintenance Facility

Construction is complete on the showcase SANDAG / MTS South Bay Bus Maintenance Facility, which has provided MTS with a state-of-the-art expansion of their existing office and maintenance complex in the City of Chula Vista. This project was the first design-build project of this scope administered by SANDAG, and CALTROP provided construction management services with experts in the design / build delivery method. The bus maintenance building is a high-bay, state-of-the-art facility with special systems designed to minimize downtime for the vehicles while maximizing efficiency of maintenance activities for the fleet. The project was LEEDS Silver0 and Cal Green- compliant, and designed to minimize waste in daily operations, and maximize energy and resource efficiencies.

“MTS would gladly work with CALTROP Corporation again on any future projects as they exceeded our expectations for construction management, project management and inspection services.”
