The Commonwealth of Virginia Department of General Services contracted Commonwealth Architects, along with design-build partner S.B. Ballard Construction Company, to design and construct a 1,000-car parking deck in downtown Richmond. The 357,000 SF deck is located adjacent to the Main Street Centre high-rise and provides parking for Commonwealth of Virginia employees. The parking structure, which is 11-levels high, is rectangular in nature, containing two bays of double loaded parking aisles. Each bay consists of a ramp, which ascends one parking level, and a flat landing at each end. This allows for two levels of vertical travel for each full revolution of horizontal travel.
