No, but the north and south side rarely progress at the same rate, so people have been referring to them as the north core and south core. It's still technically one core though.

3 Questions for Quentin Brathwaite, Port Authority

http://www.lowermanhattan.info/news/...tin_78870.aspx

"The Port Authority is operating several giant cranes inside the WTC site, with one “mega crane” in place -- how does its size benefit construction progress?

Mr. Brathwaite: The largest crane that will be used during the reconstruction of the World Trade Center -- a Manitowoc 18,000 -- is already on site at the western edge of 1 WTC. With an 800-ton capacity and a boom longer than 400 feet, assembly of the 18,000 requires nearly a full week.

It was used to place some of the jumbo steel columns that frame 1 WTC’s perimeter and first three floors of the building. Each individual column is 60 feet long and weighs 70 tons. (To put that in perspective, every 12 inches of steel equals the weight a Honda Civic.) Currently all 24 jumbo perimeter columns have been installed and are clearly visible to passers by. In fact, additional steel has been installed above the columns and structural steel currently tops out over what will be 1 WTC’s fifth floor.

The Port Authority’s contractor responsible for installing WTC Transportation Hub steel will reposition the 18,000 in the East Bathtub in the first quarter of 2010. Cranes of this size are absolutely essential for placing the massive steel members that comprise the structure of 1 WTC and the Transportation Hub. Just as the 18,000 was crucial to placing 1 WTC’s huge perimeter columns, it is needed to install the largest and most complicated steel members required to realize the iconic design of the Hub.

The Port Authority is working closely with its contractor to ensure the crane obtains the necessary approvals and is repositioned on the site in a manner that minimizes impacts on surrounding traffic and the community. While the coordination and planning required to bring immense cranes such as the 18,000 onto the site is considerable, they are essential to completing the WTC redevelopment. Moreover, their presence serves as very tangible evidence of the progress we continue to make in the reconstruction effort."

Don't think of it as losing, think of it as outgrowing.

No more mega steel beams. Are they going to, take it apart just to move it around the corner? On to the next phase. Soon they'll just be tower cranes and that a pretty good sign it's moving up.

Looks like the joint piece for the diagonals will be put directly on top of that new column! It is even slightly higher than the ones of the previous floor. The first quarter of 2010 will be very exciting, if the weather is not too bad. And dont forget the joining corner columns too...

Is that the core steel for the last two mechanical floors?

Edit: It's one floor, and the first steel beam has gone up for it.
