Iconic symbols of recovery: rebuilding the 9/11 sites

Following the attacks of September 11, 2001, three U.S. sites — the 16-acre World Trade Center, parts of  the Pentagon and the Flight 93 crash grounds — required careful, complex reconstruction. The projects would become American symbols of resilience and recovery.

Challenge
The World Trade Center (WTC) redevelopment called for more than two dozen projects and involved an array of federal, state and local stakeholders as well as public and private financing. The Pentagon site needed two security screening facilities — one at the Metro and another next to the 9/11 Pentagon Memorial. The memorial at the Flight 93 crash site in Shanksville, Pennsylvania, required the study of potential environmental impacts.

Solution
Louis Berger was honored to be chosen to work on all three sites of 9/11 reconstruction. Selected by the Port Authority of New York and New Jersey as program manager of the first phase of the WTC site redevelopment, Louis Berger provided scheduling, cost estimating and construction supervision. Following the 2004 completion of the first phase of restoration, Louis Berger was awarded a second contract to manage the construction of:

  • A new Port Authority Trans-Hudson (PATH) terminal.
  • The National September 11 Memorial and Museum.
  • One World Trade Center, a 3.5-million-square-foot, 1,776-foot-tall, 104-floor building, which is now the tallest skyscraper in the United States.
