Tindall Corporation announces the completion of an 11-bay, 5-level, total precast concrete parking structure for the National Geospatial-Intelligence Agency (NGA) at Fort Belvoir, VA. Serving a 2.4-million-sq. ft. office building, the fast-track, large-scale project was procured for NGA by the U.S. Army Corps of Engineers Baltimore District (USACE).
The project was implemented using integrated design-build project delivery. Brought on board early by contractor Clark/Balfour Beatty (Springfield, VA), the Tindall Virginia Division (Petersburg, VA) assisted in a complete redesign of the construction concept from cast-in-place to total precast concrete for the 5,130-space parking garage. Total precast contributed in large part to a $50 million reduction in the overall project cost.
Commencing in March 2009, the structure required only 6 mos. for manufacture and
erection. Comprising the 2920 pieces were 12-ft-wide x 31-in.-tall double tees, 8-in.-thick x 74-in.- tall spandrels, 24-in.-square columns, 8-in.-thick wall panels, 13-ft-wide x 10-in.-thick lite walls, 10- in.-thick shear walls, 40-in.-square inverted tee beams, 8-in.-thick flat slabs and precast stairs and landings. Design features in the RTKL/Kling Stubbins design were 7 stair towers, a center wall supporting stairs, 2 elevator towers and two concrete mix colors
