Crews recently topped out the $640-million Walter Reed National Military Medical Center in Bethesda, Md. The design-build project is being constructed on the site of the existing National Naval Medical Center as part of the Base Realignment and Closure Act of 2005 by a joint venture of Clark Construction Group, Bethesda, and Balfour Beatty Construction, Fairfax, Va. When completed, the building will feature a new 560,000-sq-ft ambulatory care clinic and a 165,000-sq-ft in-patient addition to the existing hospital. The team also is constructing an eight-story, 944-space patient parking garage, a 700-ft-long logistics tunnel and 450,000 sq ft of phased renovations to existing facilities.
