Pentagon Reconstruction - The Phoenix Project

The Phoenix Project involved rebuilding the section of the Pentagon that suffered structural damage as a result of the September 11 attack. The area of work extended from Corridor 4 to Corridor 5 through the outer three rings of the Pentagon – E, D, and C. The 400,000 square feet of space fell along the dividing line of Wedge 1 and Wedge 2.

The Phoenix Project scope of work included rebuilding the core and shell of Wedge 1 and shell of Wedge 2. In the weeks immediately following the attack, 10,000 tons of debris was hauled from the collapsed area of the building to safely continue the recovery effort. A total of 50,000 tons of debris were moved from the site during demolition.
