I think I'll trust the guy with the plans - Mr. Zen. What doesn't make sense about it? That it'll be incorporated into the concrete structure? You can see all of the protrusions on the steel where it'll be tied into the floors.

It makes sense!

The cranes used jump from floor to floor using the climbing device at the bottom. But if you look at these two huge fellows (WTC 1 will be built by steel, so big and heavy parts) you will see that their bases don't fit in any elevator shaft. Their bases are even that big, that a hole in the floorplates allowing them to climb there would reach from the core to the edge of the building. The third possibility would be to attach them outside to the building but then the overhang would be bigger, which reduces the max. load.

So the best way is to build a steel structure where the crane sits on top and which climbs ahead of the concrete core...

So you are saying the steel structure there will eventually be incorporated into the central core and it is not build on top of the core and raises as the core itself rises, right?

Yes, I would guess the steel will be covered with concrete. Raising the whole steel structure would be a headache.

Maybe structural reasons and the cranes are it's purpose.

Ok, thanks guys. I'm a enthusiast observer and was curious on the method.

BTW it's almost 3 years (wow) since I visited the site, my pics were posted back then on the previous thread.

How much was the helicopter tour? And what was the company? I'm going to be in NYC in a few weeks.

Liberty Helicopter Tours. There's a couple different options for the tour. Like I said I'd recommend them to anyone. I showed up an hour early and we left within 10 minutes of our arrival. I ended up with a window seat, but I wouldn't count on it.

This might help. The erecting steel goes all the way to the top as does the core.
It's there to give the floor beams something to bolt to and also acts as a header above openings in the core walls.

As for construction wise, the FT looks likes like its about to tower up. I guess the basement was the hardest to do, so it took longer. (2yrs)!! T4 looks like its going to be finish before FT. Now if the Chinese or Japanese had control on this project, we would have been seeing the FT from miles away by now.

Not likely. There are some pretty zippy projects going up in China and Japan, but if they were being built in downtown manhattan on the grave of almost 3000 people, they'd probably be at the same point we're at now.

Agree. That picture = the question: "So where's the other one?"

What "fountains" are you talking about? Do you mean the memorial pools? If so, no. Why would they be?
