WTC1 is impressive... even without overstating reality.

WTC1 uses 14000psi concrete. Back in 1988, Seattle's Two Union Square used 19000psi concrete. http://www.cement.org/tech/ctt_timeline.asp

How about them pyramids?

But in all seriousness, has there been a non-biased comparison to some of the still-under-construction Chinese supertalls? They have insanely massive cores and super columns clad in concrete. It would seem that national pride on both sides would lead the press to claim the "strongest" moniker without really delving into it... earthquake resistance, fire resistance, long term concrete stability, etc.

It's a vain debate as about all the mega talls all over the world,design and engineering are Made in USA.
American standards are the highest and most requiring.
That's why one WTC cost is 4 billions.
...And about the origin of skyscrapers we can tell FULLER is their real father as for his Tacoma building in Chicago he created street cages that supported all the building's weight.
That was obviously the greatest contribution(with OTIS and the elevator) to the concept of skyscraper.
...Just wanted to restore the truth.It's not nationalism:i'm french italian!!...

On 1 WTC it's a shame they didn't build two of them.
Two of them would have been very awkward and redundant against the skyline. The diversity with all four towers adds character and charm. I like the new "Crystal City".

Also, it looks like they are working on preparations for the roads!

It cost 4 billion because American construction workers are among the highest paid in the world and they only work 7 hours a day and thus it takes twice as long and costs twice as much to a build a building in USA than in other countries. Some of these construction workers after including overtime make six figure salaries.

Also??...are you jealous!?..i think they deserve their dollars more than the yuppies from wall street!!
That's the honor of someone like Frank Gerhy to refuse any contract in a country where workers are not decently paid.
For the rest,all over the world,made in USA is synonymous of top notch quality.

It is the strongest used on a supertall though. Most people tend to forget that part, however.

Stronger than the concrete used to construct dams

Before everyone starts making these claims that this is stronger than this and that, could you please post links to articles or documents classifying all this because without tangible proof it simply sounds like mere speculation and assertions. It is a fact that 1WTC is a very strong and resilient building, but if you claim that the concrete is stronger than that which is used for dams or what not, could you please link us to something verifying this? I ask respectfully because I am very interested in learning more about this. And I like proof and not biased speculation.

Yeah, **** all those criminals on Wall Street, the construction workers who built Tower One do deserve a large sum, probably more than talk show hosts too.

Agreed. Many Wall Street clowns like John Corzine deserve imprisonment for economic terrorism. The workers at 1WTC have done an incredible job. They deserve all the money the Wall Street cronies get for doing nothing.

This article from 2011 is a good place to start: http://www.rew-online.com/2011/06/01...uper-concrete/

I think people aren't quoting articles because this has been covered pretty extensively since the beginning of construction. That article goes into fairly deep detail about the development of the WTC's concrete, and I'm not nearly well-versed enough in construction to break down some of the specifics, but the gist of it is that it's 14,000 psi steel-reinforced concrete -- where previously anything over 10- or 12,000 psi was considered extremely high strength.

It'd be hard to compare a dam, because the walls are so much thicker, but Hoover Dam, for instance, had (I believe) 5,000 psi concrete.

Some have said that the concrete developed for this project has actually helped jump-start a revolution in super-and-megatall towers that couldn't have been safely built before.

On top of that, there's the design itself, which includes safety features such as the much-maligned "bunker" base and protected stairwells with ultra-thick walls.

My girlfriend works in and studies disasters and emergencies, and she's concluded that in a major earthquake or a bombing of any kind, inside One WTC is just about the safest place in NYC you could be.

I don't think the base will feel as bunker-ish when it is done. I've visited plenty of art museums with no windows and they feel totally fine.

It didn't seem like one at all to me. Rather, it was like a gorgeous, giant mirror.

I am not jealous.

I am just saying that this tower costs 4 Billion doesn't mean that the building materials that are used to build this tower are super expensive its just that the Construction Workers building this tower are very highly paid and don't work long hours and thus it drags out the construction process which escalates costs.

If this building was being built in China or Dubai, it would have been completed in 2 or 3 years.

This building started construction in April 2006 and won't be until January 2014 until the tenants move in. That's 8 years.

Europe and Japan were rebuilt faster after World War II than this building.
