Montgomery County Equipment Maintenance & Transit Operations Center

Rockville, MD

Montgomery County needed to replace its existing Equipment Maintenance & Transit Operations Center (EMTOC) to make room for new transit-oriented development adjacent to the WMATA Shady Grove Metro Transit Station. Maintenance Design Group collaborated with a local architecture/engineering team to design a new state-of-the-art facility to house a 200-vehicle transit services depot, two 100-vehicle highway maintenance and operations depots,  and a heavy vehicle maintenance facility responsible for servicing 900 vehicles in the County’s fleet.

Nestled on two adjacent sites separated by an interstate highway, the team used urban planning concepts to create a high-density building footprint, stacking the administration and operations areas above the maintenance bays, and staff parking above heavy vehicle and transit parking. This approach maximized green space and minimized the impact on the surrounding wetlands, also creating a more efficient and effective circulation route for staff to operate within the facility without conflicting with vehicle movements for the heavy vehicle maintenance facility and bus fleet. This compact design provides more safe and efficient operations.

Project Highlights
• Existing sloped topography and dense vegetation used to screen and minimize noise disturbance from the surrounding residential community, providing views of the green roof and administrative facade from the road.
• Space-saving vehicle maintenance system technologies such as vertical lift module, automated stack warehouse systems, and vertical carousel tire storage racks to reduce space while increasing operational efficiency.
• LEED Silver design includes abundance of natural lighting within the maintenance bays and work areas, high efficiency LED lighting, hydronic heated maintenance bay floors, and geothermic heat pumps.
