Hell, they'll need the platform to hold the electric cable if they're going to heat up those beasts. A hundred tons of three inch thick steel makes a pretty good heat sink. It will probably take two or three hair dryers at least.

Getting an early start today. Hopefully they can put up another two before the end of the day if the weather cooperates.

I think they will just finish the first corner of the building today. The Corner columns seem to be shorter, so they will also have to add some connection beams on top of it, to connect them to the bigger ones.

Looks like they are pouring more concrete on the west side of WTC1. Hard to tell exactly where, though.
