The core of Rosslyn, Va., is changing with the completion of Central Place, a mixed-use residential, retail and commercial development. When completed in 2017, the office tower will house Virginia's first public observation deck with amazing 360-degree views of the D.C. monuments and landmarks. The 33-story, 750,000-sq-ft structure features post tension and mild steel reinforced slabs with an 18-in.-thick transfer slab observation deck on the 31st floor. The project will use more than 64,000 cu yds of concrete.
