Steel installation for One World Trade Center has reached the 20th floor equivalent level, raising the tower to 200 feet above street level, the Port Authority announced today.

The agency's Commissioners were given an update on the project today at the Board's  World Trade Center meeting.  Commissioners were told that steel has risen to the 20th floor equivalent level.  To reach the 20th floor, the Port Authority's steel contractor, DCM Erectors, has already erected nearly 8,000 tons of structural steel - 700 tons more than the total amount of steel in the entire Eiffel Tower.

Photos of One World Trade Center are available on the Port Authority's Web site - -- and on Flickr.

Currently, ironworkers are installing 16 giant steel nodes on the 20th floor level.  Some of the nodes are as large as 175 tons and as high as three floors.  These giant pieces act as joints between the steel framing for the building's podium and the steel for the remainder of the tower, and represent one of the signature elements of the building's unique design and appearance.

The above-ground height is in addition to the 60 feet, or four floors, of the building below street level, which will contain mechanical space, fuel storage, water tanks, parking, retail and a lobby for the observation deck elevators.

Since construction began, more than 60,000 cubic yards of concrete has been poured for the tower, both above and below ground, almost as much concrete as was used to build the entire Empire State Building.

The initial 20 floors of the tower consist of a lobby and several mechanical floors, which required more complex construction due to security and the configuration of the floors.  The next 69 floors will be standard office floors and will be built at a quicker rate.  The tower is scheduled for completion in 2013.

Port Authority Chairman Anthony R. Coscia said, "The construction progress on One World Trade Center is great news, but we know more challenges lie ahead.  The Port Authority will confront these challenges head-on as we continue with the rebuilding of the site."

Port Authority Executive Director Chris Ward said, "This progress is one more sign that the site is not a pit anymore.  At the same time, we must continue working aggressively each day to keep up the momentum."

At the meeting, the Board also authorized the following World Trade Center-related actions:
