Transit Maintenance Facility
City of Mesa, Arizona

GLHN provided professional mechanical and electrical design services to RNL Design, Inc. of Denver for the $14 million facility. The facility was designed to be entirely Compressed Natural Gas (CNG); no liquid fuels were to be dispensed. Mechanical design included HVAC and plumbing design for five buildings, as well as all-outside-air systems for the vehicle maintenance bays coupled with an open-path compressed natural gas detection system designed to open bay doors and activate building purge fans to vent lighter-than-air fuels out of the building. Electrical design for the project included interior and exterior lighting systems in compliance with local lighting ordinances, and power systems design for all buildings, as well as 12.47kV service and distribution for building systems as well as the electrically-powered natural gas compressors for the fueling facility.
