On November 3, 1998, Fairfax County Virginia voters approved a $99.92 million Public Safety Bond Referendum for new safety projects. Funding for new public safety is based primarily on the residential and commercial growth and training related needs of the county's public safety agencies. The referendum funded the design and construction of The Judicial Center Parking Structure. This structure will accommodate approximately 2,100 vehicles in response to increased traffic from the expansion of the Jennings Judicial Center in Fairfax County.

CEG began work on the $20.6 million dollar precast parking structure in January 2001 after contracting with the Shockey Precast Group of Winchester, Virginia. The structure contains seven levels and 604,000 square feet of parking area. Two of the seven levels of parking are partially below grade. The footprint of the structure is 466 ft. x 183 ft. with two 21 ft. x 15 ft. stair towers. Additionally, the main stair and elevator tower located outside of the structure is triangular in plan and approximately 60 ft. x 52 ft. It includes elevators, stairs, storage rooms and a 30 ft. x 17 ft. planter area on the second level with 400 psf loading. The top level of parking has five planter areas with the largest being 60 ft. x 14 ft. These planter areas are also designed for 400 psf and are supported on double tees with narrow widths. There are over 1,700 precast components including architectural columns, stairs, elevator walls, shear walls, horizontal ramp walls, beams, and spandrels with thin-accent banding. The stair towers alone contain some 300 architectural components including sills, lintels, watercourses, copings, and cornices.

The main stair tower on Page Avenue also features a precast pedestrian bridge to provide sheltered access to the existing parking structure across the street. The pedestrian bridge is 40 ft. high and 128 ft. long with a 70 ft. span over Page Avenue and is constructed of precast moment frames.

The exterior architectural spandrels contain reveals and a 1D2" face brick strip 2'-0" high that was cast integrally with the spandrels in the plant. The grade level panels, stair and elevator towers are completely covered with field laid brick and precast copings. The finished structure showcases the fine details developed by Wisnewski Blair and Associates, Ltd. and the high quality work of The Shockey Precast Group.
