Silverstein Properties, the firm responsible for developing the new WTC, plans to open the 9/11 Memorial in September 2011 and the accompanying museum in 2012.

The new WTC will consist of five skyscrapers (2, 3, 4, 5, and 1 WTC – Freedom Tower), the WTC Transportation Hub, a retail complex and a performing arts center.

7 WTC, which opened in May 2006, incorporates a 52- storey, 1.7-million-square-foot skyscraper, which marks the gateway to the new WTC.

The building is made of 2ft-thick reinforced concrete walls protecting the building’s core for the full height of the tower, including the lobby, exit stairways and elevators.

7 WTC is also equipped with an enhanced evacuation system, the most pronounced being the exit stairs.

Libeskind, who won a competition to become the site’s master planner, focused on the Freedom Tower, with an asymmetrical spire with a similar height of 1,776ft.

In addition, the other code designs include advanced fireproofing material ten times the adhesiveness and twice the thickness required by building codes.
