Steel Trusses Used In Post-9/11 Pentagon Reconstruction

摘要

On September 11, 2001, the first of five Pentagon building sections targeted for renovation was underway. That morning, a hijacked Boeing 757 went through a corner of that wedge. More than 2,600 workers were in the disaster area, but there were only 125 casualties, thanks in large part to just-completed structural renovations. In all, a million-square-foot area was damaged as a result of the crash. About 400,000 sq. ft. of space ultimately had to be demolished. Now, almost ten months later, like the fabled phoenix bird that rose from the ashes of its destruction, the Pentagon is rising stronger and safer from the destruction of 9-11. Contractors working on Project Phoenix, as the rebuild of the terrorist-damaged section was named, are working at an extraordinary pace to meet a September 11, 2002, deadline to have the damaged wedge of the outer "E" ring of offices rebuilt and ready for occupancy.
