Construction on One World Trade Center, formerly known as the Freedom Tower, has reached 200 feet above street level.
The Port Authority announced today that steel erection for One World Trade Center has reached the 20th floor, or 200 feet above street level. For this particular project, that means that 8,000 tons of structural steel have been installed by DCM Erectors—700 tons more than all the steel in the Eiffel Tower. Currently, ironworkers are installing 16 giant steel nodes, some as big as 175 tons, which will act as joints between the framing of the podium and the rest of the tower. From here on out construction should move much faster, and completion is expected in 2013. The first 20 floors required very complex framing, whereas the remainder of the erection will be standard office floors. You can view more images of the construction at the Port Authority’s Flickr page.
