Steel seems to be shooting up now, whether it's the FT or the memorial. Thanks for the updates NYguy!
Well, no one can deny that there is any work going on at the WTC site, even with the delays on other towers. All anyone need do is pay a visit to the site to witness just how busy it is these days. But what is shown in these photos is just a drop in the bucket compared to what is to come...

4 WFC, GS, Verizon, and the FT are going to make quite the four corner effect when all is said and done. Looking up at that intersection is going to be amazing.

Its not going to be perimeter steel its part of the core which will be covered with concrete.
I am relatively new to skyscraper construction, and have never heard of such a technique, is this something that has been used many other places, or is it something be used here do to the nature of the structure. Like the concrete and steel design makes it more able to withstand fire and terrorist attacks?
Ive (like everyone else here) followed many projects from first proposal to toping out, but seeing the two memorials bieng outlined and the core and towers start is probably the most exciting thing ive seen so far. These pictures will be historicly valuable one day.

The perimeter structure will be steel so this allows the steel floor beams to attach to the steel under-layer of the core. Aside from openings for the connection the steel you see in the core will be encased in concrete.

I agree with antinimby. I think this steel too thick to be covered. And those little nails only top and the bottom of the steel beams, that's mean is some kind of support to the floors and ceiling.Or the concrete only goes uprightly between the beams.
Here's what it is, according to ZenSteelDude at WNY.

I really wasn't expecting it to go up at this time, I thought the core wasn't quite high enough. As you can see it starts about 35' above the ground floor and well be continued all the way to the roof.
The lower beam defines the 2nd floor, and the upper one the 3rd floor and if you look closely at the pic TheWtusi posted you can see the column closest to the camera is actually hanging in mid-air waiting for the north core.
rofl, seriously. It's hilarious when people are skeptic of what the top engineers and architects in the world are doing. people did the same thing with the burj and wind resistance too.
^ They are all out to get us. "Hmmm, what can we build today to confuse all those skyscraper enthusiasts?" They could play cruel jokes like building frames with wood 2x4's

I think this steel is stable. It looks like any other permanent structural steel.
