uaarkson answered your question and I have no further info on when.

If I do not respond to a specific question it usually because I consider that question already answered, intelligently, by another member.

I thought that 16 office floors had to be up before cladding was to start. Then october.

I was wondering which building is and was structurely stronger, like which building could withstand more punishment, Original Tower1 or Tower 1V2.

Steel Fabrication 101
 

Thanks Dchan and Zensteeldude foe the engineering tutorial.

Now I'm ready to design my first bridge! :cool:

Slider Crane Update
 

Not sure if this has been covered, but I met up with a friend who is a steel worker on the trade center this weekend and got details about the slider crane on the north east corner:

1. It will run all the way up to the 80th floor
2. Is designed to carry the rebar used in the concrete floors

(He had never seen this technique used before).

Amazing job, this one actually looks real!:tup:

Other than 7WTC somehow completely got lost in translation. :haha:

You're right! I think it's just the angle though because in the far-off shot you can see it

Yeah, no. I don't know who started that rumor but I don't see any evidence of that either. I mean we already have the (supposed) glass, its look vastly different.

Haha, that's not actually 7 WTC in the shot, it's a rendering of it far from accurate.

The glass on the Freedom Tower is supposed to be more "whitish", if that makes any sense. Also, there is a mockup posted here. Silverstein initially said all of his towers would have the same glass, but I believe that has changed, particularly with Tower 4.

I realized today that although I kept referring to "thermal stresses" in my last post, I actually meant "residual stresses". Sorry about that - it's been a while since my last steel design class. :)
