Ooops... there are at least 2 of them... Found another one, which is located at the NE section of the tower. Seems like I was wrong and there will be indeed 4 columns, each located at the NE, SE, SW, NW areas respectively, each connecting one perimeter column to a corner of the core. Apologies for the guessing, but drawings are a bit outdated.

Wouldn't it be 2?
The steel that they raise in place fits one or two floors?

You're confused! Still 4 jumps to reach the roof.
