When it was attacked on 9-11, the Pentagon was in the midst of one of the most complex renovation projects in contemporary history. The Pentagon Renovation Program (PenRen) was designed to build a new vision of the Pentagon, one that would keep the historic structure while enabling it to meet the needs of the future. Six years after the project began in 1992, however, serious budget and schedule overruns endangered the entire project. As Wedge 1 of the Pentagon was nearing completion, Flight 77 hurtled into the Pentagon on September 11, 2001. After the attack, the Phoenix project was born, with intent to rebuild the damaged area before the one-year anniversary of the attack. 28 days before that anniversary, the Phoenix Project was complete — $194 million under budget. The contract’s schedule was accelerated by four years, and if not for the nimble nature of the design-build contract, this challenge would have been nearly impossible to overcome. After ten years of design and construction, PenRen was complete, meeting its design mandate and staying true to the Pentagon’s historic past while also embracing the future by building for anticipation of future needs. PenRen was named the Best Overall Project at the 2011 National Design-Build Awards.
