Capital Area Transit Operations and Maintenance Facility

Raleigh, North Carolina

Capital Area Transit (CAT) administration, operations, and maintenance facilities were more than 30 years old and in need of updates, repairs, and expansion, which the current site could not accommodate. The current site, combined with an adjacent lot, held a 90-bus fleet and had inadequate employee parking. Further agency growth was halted until a new facility at a larger location was developed, so time was of the essence. To speed the completion of the project, a design-build approach was used to deliver the facility. MDG assisted a local Design Team and contractor to deliver fast tracked, 60% bridging documents in just three months so construction could start as soon as possible.

The maintenance facility includes eight running repair bays, one repair bay for articulated buses, five PM/inspection bays, a paint booth sized for articulated buses, one body repair bay, one chassis wash bay, a comprehensive service facility (with two lanes that include fare retrieval, expandable to four), diesel fueling, interior cleaning, and a two-bus wash lanes. The design team worked with numerous natural and man-made challenges on the 23-acre site, including wetlands, extreme topography, electrical distribution power lines, limited access, and tree conservation zones.

Project Highlights
• Geothermal wells provide high efficiency heating and cooling.
• Radiant floor heating in the large maintenance building to help maintain optimum thermal conditions.
• Reflective white roofs and concrete rather than asphalt paving that minimizes the heat-island effect, reducing demand on air conditioning systems.
• Natural light through windows and skylights combined with sensors on the light fixtures reduce the amount of energy used for lighting the buildings.
• Water-saving plumbing fixtures and rainwater collection cisterns were utilized to minimize water usage from the municipal system.
• The materials selected for the facility include rapidly-renewable and long-life durable local materials.
