If you want to see a stunning contrast go take a look at the thread for the London Shard. They're putting very very little rebar in the support columns and overall it looks so much weaker than this building. This is surprising considering it will be the signature building of London and they have always been the target of terrorist attacks.

Some day the workers will be able to look "down" on WTC 7...

Since they installed the 60' beams,
the excitement for this project, has returned for me.

Well Zen said on another forum that most of what we've seen so far with all of the rebar and steel is not because of 9/11, but updated New York City building codes. The building must survive a magnitude 5.0 earthquake or higher, and a category 5 hurricane.

Dont be too euphoric about the recent progress, there is still a lot to do. I think we wont see any significant heigth changes until all the lobby columns are put up and plaza level is done. But I could be mistaken.

All fine and good but WTC1 is built significantly stronger than any other building ever has been in NYC including WTC4 and that is certainly built to the same codes.

1WTC is also quite a bit taller....

They have rebar laid for pretty much the entire rest of the memorial plaza today. Looks like they're really moving so it will be ready on Friday for the families of the victims on the eighth anniversary.

I cant wait for these to be done! I love our democratic, capitalistic society, our freedom and constitition. On 9/11, terrorists tried to destroy the soul of America. They failed. For the land of the free, and the home of the brave!!!!!!!!!

This is probably correct. It will most likely be winter before the base is completed. There was a press release at one point stating it will rise about 1 floor a week at that point. But there is a lot to do until then. At this point next year it should be 15-20 floors above the base and really starting to pick up steam.

I'm pretty skeptical of "1 floor a week" talk. It's been taking 6 months to do one sub-level. I know we've all heard and discussed the difficulties of building in tight places like lower manhattan, PATH tracks, logistics, etc. But it's ridiculous watching cement trucks line up a couple times a week over at 4WTC, and 1WTC gets maybe a cement pouring once a week or every two weeks at best.

It's easy to sit here and monday morning quarterback, but I really wish NY had just shut down the PATH tracks from the beginning and focused entirely on building everything to grade. Forget about grandiose perimeter columns, and core steel (height). Just get everything to plaza level, then restore the PATH line service, and then build up.

I always thought the "one floor a week" was BS. The core can't rise that fast and the core steel can only go so high before being encased in the core cement.

The sequence would go something like this 1) core columns 2) Perimeter columns 3) 170+ floor and spandrel beams 4) decking 5) temporary shoring installed 6)about 2,000 shear studs welded to the floor beams through the decking 7) re-bar placed 8) slab poured

The higher they go the more time it takes to get everything up there.

I'm thinking more like 2 weeks per floor.

PS: I do this for a living and I am living well.

One floor in 2 weeks would still be faster than the current (already fast) progress. The tower would be finished in 2 years then. but it looks like the rebar will take most of the time...

I was just looking at the picture and got to wondering how they'll get the 400' spire up. Will they use something like gin poles to build it like they would a radio tower?

The plan was to use one tower crane to hoist the 20 foot high sections into place. I doubt a redesign of the spire would alter that.
