This case study article describes the new parking garage facility at Shady Grove, Maryland, part of the Washington, D.C. Metro system. The facility, built almost entirely of precast concrete, gives Shady Grove's 13,000 daily commuters an additional 2,050 spaces, bringing the total at the location to 5,467 spaces. The author describes three elements of the project: time of construction, costs (both initial and long-term lifecycle costs), and aesthetics. The garage was designed to echo the design of the Metro stations, which have established a recognizable visual image. The parking garage's four rounded stair towers used curved precast panels to achieve the desired look and enhance the overall appearance. The total-precast design includes components that are typically produced in precast concrete, such as shear walls, inverted tee beams, spandrel beams, and double tees. But precast in this project was also used for elements that often are constructed in steel, glass, and masonry (the stairs, elevator tower, and elevator machine room). The author also notes that precast concrete's ability to resist harsh weather was a key factor in its favor.
