Pentagon
Arlington, VA
The Pentagon is the headquarters of the United States Department of Defense and the largest low rise office building in the world at 6.5 million square feet. Conceptualized in mid-July 1941, the Pentagon’s original parameters were designed to accommodate the increasing number of War Department civilian and military personnel working in the Washington, DC area just before America’s entry into World War II. Construction began on September 11, 1941, and was completed by January 15, 1943. Having never experienced a major renovation, the Defense Authorization Act of Fiscal Year 1991 established funding for such work. The Pentagon Renovation & Construction Program Office (PENREN) was born out of this congressional act, leading to the first renovation activities in 1993. The renovation of the five wedges is scheduled to be completed in October 2011, a full three years ahead of schedule due to the events of September 11, 2001.
The renovation of the Pentagon was a multi-phase project encompassing a period of almost 13 years worth of construction. The work performed by National Fire Protection includes the renovation to the various areas in the Basement and Mezzanine Levels, the renovations to the Wedges (Wedge 1 through 5), the installation of a state of the art fitness area for the use of the Pentagon employees, and the installation of a new entrance for the Metro. The renovations consisted of the entire demolition to the base structure with a completely new architectural, mechanical, and life safety upgrade. The Phoenix Project was the rebuild of the areas destroyed by the 9-11 attacks on the Pentagon. As per the commitments made by then-President George W. Bush, this design-assist project required full completion of the reconstruction for occupancy in a 1 year period. This accomplishment was marked by the rededication of the building on September 11, 2002.
