DRS was responsible for providing architectural and engineering services for the renovation and expansion of two bus garages for the Port Authority Transit of Allegheny County.  The garages contain a combined total of more than 25 full-service maintenance bays.  There also are paint booths at each garage.  In addition, service lanes for both garages include 10 fueling islands and four bus wash lanes and indoor parking to accommodate 550 buses. 

Additional spaces include administration areas, training rooms, driver areas, locker rooms, parts storage and toolbox storage.  Another part of the project was to provide fuel and supporting lubricant tanks with a capacity to serve the fleet of buses.
