Hi Myster E, no problem! Yes, I was basically surfing the channels as you do and just caught this documentary on ITV4, I believe. I love documentaries like this anyway. It was really good, but unfortunately only this first part showed some computer graphics of Shanghai Tower.

It's amazing what's going on with China right now. It's like everything is all positive there.

I think China could build a building taller then Burj Al khalifa if the economy stays this strong.

Skyscrapers have to do with density and land value. Shanghai has extremely high density, and land values that are skyrocketing. That is why a super tall is being built here. They are simply running out of space, which isn't the case for other cities out there, cough, Dubai, COUGH.

Well, one thing is for sure, many old skyscrapers built in shanghai have spires for some reason, you know what I mean. And almost all of them looks out of style today. But I'm glad to see the new ones are all shining boxes with real height, clean rooves. People in this city prefer the quality to the height now.

Supertalls have less to do with land values. Have to do with ego (and Dubai again )

Once a certain height is surpased, the cost to build higher and higher grow exponentialy... Be sure that with 1,2 Billion USD, the cost of SWFC, you can buy land and build several 250m towers that have more floor space than SWFC have. SWFC, Jin Mao, or Shanghai Tower are built to be a landmark, for city pride, etc (ego again).

Well, i guess it was all planned though. The masterplan for the pudong area was to have three supertalls (really tall ones about 400m). About ego, a little bit. If SWFC was not halted by the Asian crisis in the 1997 period, then its height would have been 460m, and SH would have been shorter.

exactly, its a statement of power, a super tall is as much about ego as office space.

I presume these guys know what they're doing, but can anyone explain to me how something the size of the Shanghai Tower is supposed to stay stable on land that used to be a swamp?

This is how it works .They basically dig a huge whole and fill it with concrete mixture which is very rock hard when it solidifies .Then they puncture it with series of poles which go deep down .Imagine you have a hard ground on which you have bread (bread basically represents the muddy swamp of pudong now Put some hard fried bacon on top of the bread and press it into the bread. (Bacon might represent the concrete) Now take some chopsticks run them through the bacon the bread into the hard ground below very deep. Now these chopsticks serve as load bearers for the building and you build everything around it. Are you clear with this analogy.

They stick a lot of very long piles into the ground, until it reach the bedrock, and if the bedrock is too deep, they let the frictional force to do the job. (not sure if Jin Mao and SWFC stand on bedrock, I'm sure that Burj al Arab stay only by friction force)

To understand better, try to put a long stick into mud. Even if the first part slide easy, the deeper you go, the harder it gets. And when frictional force is stronger than your power, u can't go deeper...

If the piles reaches the bedrock, they actually drills them into that right?

Yes, but from what I remember, bedrock in Pudong is very deep, like hundreds of meters... I can't find a Discovery documentary with the building of Jin Mao (I guess it was removed), there where very good explanings (with animations) of the entire piles system...

They go deeper with more numbers of piles (for SWFC and ST), but the principle is the same.
