About the Project

The Pentagon is the largest low-rise office building in the world, making the renovation of Wedges 2-5 the largest renovation project in contemporary history. The 4.5 million square foot design-build project included complete demolition and abatement down to the concrete structure; hardening of the exterior envelope; upgrading of all MEP and Life Safety Systems; building flexible office and command center space; restoring numerous historical building features and relocating the Secretary of Defense, the Joint Chiefs of Staff, and the National Military Command Center. The renovations spanned over a decade, during two active wars requiring extreme sensitivity to not impede 24/7 military operations during the massive renovation.
