Thx.
Enlighten us!
These are one of the thickest steel beams I have ever seen. Compare them with the workers on the site. Some beams are 3 or 4 times as wide as a human.

I watched the discovery channel and analysis show they do happen as they have in the past and another major earthquake is certain to strike at one point.

On Topic:

This tower is progressing nicely. I hope we don't see more delays from the Port Authority.

i think that you saw the beams as hollow but in this case, the beams of this tower are solid-steel...and if I am wrong, someone please correct me

I think - because of both: financial problems and technical complexity.

Although the most of Manhattan locates on rocks, this area is artificial and the whole basement here was strengthened when initial WTC complex was built in 60-s. After 9/11 it took a lot of time to check and fix damage to basement walls and to ensure that the walls are able to safely serve new construction.

Also this place is very important transportation and infrastructure junction: many existed subway lines, communication, plumbing and sanitation networks had to be repaired and rebuilt after disaster to allow normal functioning of the whole downtown district before any new construction began. Unlike a lot of the new construction sites you have a huge city around here...

I won't ask you how do you know that...

Anyway, I forgot another possible reason for WTC1 delay:
guess, America itself is a bit more complicated then Taiwan...
(sure I respect them both ).

We also had alot of government stonewalling and community disagreements on the plans. Construction couldnt start untill everyone agreed on a plan to get it done, and since there were so many different interests that wanted different things, the fact its getting built at all is a small miracle

Well, given the fact that you are not an engineer nor an expert, you should trust that the people that are engineers, that are paid for this and who's entire career depends on this building NOT falling down because of some miscalculation, are doing their jobs and know what they are doing.

No, it's not.
The Taipei 101 tower, other than using a completely different kind of structure, whose main support is a series of columns made out 80 mm thick steal plate and hollow, subsequently filled in with reinforced concrete.

Picture of one of the columns used for the Taipei 101 tower:
image hosted on flickr


The WTC 1 tower has a main structure based on a double core of reinforced concrete each of which can stand in case the other part is damaged, that is complimented by a series of steel columns. These columns are made COMPLETELY out of steel, are the biggest columns money can buy: they were especially brought from Belgium, the only place on earth where these kind of columns are made. And in case these columns were to fail to keep the structural load that they were designed for (that is, in case of explosion given a terroristic attack like the one happened on september 11th), the core would still be able to support the load of the superstructure to be able to evacuate the building without the structure collapsing, exactly like it has happened in the past.

Lets just keep the "engineer's" statements out of this forum, or there is a possibility of making a fool of yourself.

I have read before (maybe in NatGeo) that old fault lines are present in the NYC area and a significant earthquake (5+ on the Richter scale) could very well happen in or near Manhattan. Maybe not tomorrow, or even in this century, but the possibilty is there.

Those diagonal beams on the base remind me of construction you see in California. I'm betting siesmic activity was considered by the engineers.

Anyway, special thanks to all the guys (and presumably girls) who keep us updated with pics and news.

I don't comment in this thread often, so I figure I would use this chance to say "Thanks!"
