I ask respectfully because I am very interested in learning more about this. And I like proof and not biased speculation.

I wouldn't make that up, it's been a long known fact on this forum. Here's a link bud

[QUOTE=Mercenary;106209385]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?







If i well understand you make the apology of countries where workers get paid $200 a month and about Dubai where they live at ten peoples in a one bedroom and get their passport confiscated.
You are right: Europe and Japan where rebuilt very fast...because of the american help(we learn that at school in France(Marshall plan))
One wtc is a very specific project where many financial,POLITICAL,emotional(and so one)parameters where involved.
What is weird is that despite the cost of labour in New York developers are lining up to build on every single piece of land!!
Either as an ignorant or as a troll you make stupid statments you seem to be very proud of!
Construction workers are the blood of NY:they will never get paid enough!!

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.
That article is interesting, It also says that widespread use of even stronger concrete will become common. Perhaps that has already become true given how long it has been since this tower was started.

None of the discussion in this thread has gone beyond patriotic chest thumping, like people incorrectly stating it has the highest psi concrete ever used. That isn't to say this building isn't strong or isn't one of the strongest in the world. But there has been absolutely no evidence or even discussion of if it is the strongest against an earthquake, or has superior durability in the long term, as in centuries from now.

Just making this observation will probably set off some reactionary pro-WTC or nationalistic bluster. Keep in mind that i'm not insulting the tower or saying that it is weak.

Instead, this is merely pointing out that we really don't know how it compares in overall strength. It has an explosive resistant bunker of a lobby, but does that equate to overall strength? Some of the other supertalls in the world may be using slightly less strong concrete but might over compensate with shear volume in the core and tubular super columns clad in concrete.

Has anyone else discovered that you can track northern podium cladding progress by using tower 1 base earthcam?
You can just about see by looking at the reflection on 7WTC's facade!

Too bad they just replaced the yellow "sticks" and also the netting is back

Went to the site today, base cladding has finally started on the north side.

Don't have the time to post the pics I took, sadly.

I have been registered on this site for a while now, checking for updates every day. I consider it an honor that I get to walk by this site every day. I hate that I'm using my first to defend people that have degrees in economics and finance, but I can see its necessary.

Those "criminals" you speak of do what they do and get paid what they do because few understand those kind of things. Possessing a high level degree in finance leads to a rewarding career with a high salary and bonuses. Imagine how empty and useless the new trading floors in these buildings would be without economists and financiers to utilize them.

As far as the brave people who work at the WTC site, their wages, like everyone else's, are determined by supply and demand for providers of a given service, in this case, highly skilled construction workers.

I believe they (construction personnel) deserve the money they earn, it's even higher once you add their benefits to it as well, they deserve the benefits too. Their wages are high because their job is dangerous and they have a union behind them.

They are building all of us a new state of the art set of buildings. I'm thankful they are doing so and hope to bring my business there in the future once things get opened up.

I'm a born and raised New Yorker and an economist, I look forward to reading all of the great info about this great building and site in the future.

^Struck a nerve? Hilarious how you can always tell when someone was born with a silver spoon in their mouth and has the self-entitlement to show for it.

I agree. Some forumers are just very adolescent in their remarks.
NY would be a lot more empty without its financial sector.

Does anyone know if the "inside" elevators at 1WTC are operational and WHEN will the exterior ones be removed?

Plus, I would like to know HOW will they take down the crane on the top, will they use an helicopter?

Thanks.

Just a thing about the concrete...I looked at the concrete used in the Colosseum in Rome. It is 2000 years old and solid as a rock...It seems all the concrete reinforced with steel self destructs over time. A lot sooner than 2000 years but then who builds anything thinking about 2000 years ?

In an attempt to get this thread back on track, the jacking system has been added to the tower crane. Disassembly is imminent.
