Why would they need to change booms for this ? Differnt style of crane .... but here is how it is done in Chicago ( 353 N Clark ).

1 loop ( 2x wire for every x of lift )



just couple the 2 pullys together at the bottom, run the trucks together on the top, and you have a block and tackle.
2 loops ( 4x wire for every x of lift )

Last I heard and read about the sairway it that it's supposed to be preserved
and reused for Ground Zero - possibly for the memorial.

There was a rendering somewhere that shows the stairs put next to new ones in the memorial.

Advocates who were fighting for old WTC artifacts to be saved, had won the right to have the stairway saved and be reused for Ground Zero.

Yeah, it's such a shame that most other construction projects got started way before the ones at Ground Zero!

As far as I know - they were supposed to take in entirely and preserve for the future museum as well as other pieces of original WTC (like outside metal parts)

Almost street level, the construction looks nice. I hope we can see the tower growing in the first days of 2008.

The first days of 2008, you'll see the sublevel structures being erected, with the base itself rising in June, and the entire building being topped out in 2010.

Does anyone here know anything detailed about the Freedom Tower's structure besides the fact that it has a concrete core and and a stiff, strong steel moment frame and the other obvious stuff? Will any columns rise at an angle? Will some of them be made out of concrete? Will there be steel cross bracing below grade, like with the old WTC?

If I remember correctly it is going to be a mix of both concrete and steel on the lower and podium floors (forgive me if I'm wrong).

There will be angled giant steel columns around the cercumfrence of the concrete base above street level according to the renderings.

They can be seen just behind the glass panels.

Another thing could be that the demolition of Deustche was said to a major setback the FT and another delay was said to cause the entire site to be put on hold.


So, Captain Obvious, is that your final opinion on the outlook of the Freedom Tower? Or do you have more bad news for us?

The Spokesman for the formers towers and the WTCRM has spoken. That, as always, is NOT true!

The highest occupied floor falls short of the highest one in the Sears Tower, so that means that it can't even be the nation's tallest. Also, I find it rather odd how it can even jump to 1,776 ft when the roof is only 1,368 ft. Wait a minute, it is b/c of that long spire. I don't care what the CTBUH rules says what counts, spires are cheating for height b/c they are nothing but structual elements.


What the freak part of this are you not getting?!!

For the last time, the Freedom Tower with have 82 occupied floors with 20 mech. floors. Over, done, end of story. Kaput.

seriously. If you would have told any of us on april 2006 that 4 months shy of the 2 yr anniversary of the last ground breaking, we'd still be below grade, we'd all be griping. btw, last year at this time was the excitement of those initial steel beams.....hey hey looky looky, they're still there for all to see. those things are probably no good anymore, being exposed for 4 seasons like that. this project draaaags.

The rate of building on projects like this really make you wonder what good all of our modern does us. When we look back at how long it took to build the Empire State Building and the Pentagon with the equipment we had then it's hard to believe it takes us so long to do anything today! Considering all the high tech CAD that's used for the design and all the high Tech Equipment used for construction the only possible source of the slow pace of work has to be the people. It's not beneficial to the politicians nor to the union's to complete projects rapidly! If things had taken this long to complete in the past we would have never won WWII, landed on the Moon nor achieved many other things in America.
