Why did the Shanghainese reject the height increase? If it was going to be 510m, would it be THE world's tallest?

Here it is from the other thread by 10025:

On the afternoon of 22nd November 2004, a general construction contract signing ceremony of the main body of 101-storey Shanghai World Financial Centre was held at Jinmao Grand Hyatt Shanghai. A Chinese bidding alliance, consisting of China State Construction Engineering Corporation and Shanghai Construction Group, signed the $0.47-billion contract with Japan's Forest Overseas Co., Ltd., a member of the Mori Building Group and chief investor of the project. This ended 7-year preparations for and disputes over the project, a 9-month heated contention for the bid, as well as rumours doing round that the project had been cancelled.
Winning a value share of 70% of the contract, CSCEC became the first Chinese company to win an independent general contracting right of a foreign-funded, world-class skyscraper. CSCEC General Manager Sun Wenjie, who signed the contract, expressed his confidence that the building would be an "elaborate work" of his company. With the signing of the contract, the construction team will move in the building site at any time.
Investments in the skyscraper are reported to have grown from an initial $0.7 billion to $1.1 billion. As for its height, the officially disclosed is 492m. Sources say Japanese investors have proposed that it be raised to 510m so it could surpass Taipei 101's 508m as the world's No. 1, but the Shanghai side has rejected the proposal, saying the city has a limit to building heights and an overall consideration of the skylines on both sides of the Huangpu River.


From that article, it will never be WTB.

shanghainese is getting smart this time, i guess they knew that dubai is definitely building buji dubai. If they keep increasing swfc height (redesign, more funding etc). They will never get swfc going in decades.

I LIKE IT! Okay, so these 400m-500m buildings can keep their "Supertall" category... Burj Dubai and Al Burj are in a league of their own, the "MEGATALL"!!!!!!!

Dubai hasn't redefined anything until they're actually built. I'll believe it when I actually see it. How many supertalls have been seriously proposed in the past century that never came into being?

yup, if they did anything seriously wrong when digging the hole (which obviously is finished by now), the Jin Mao will come down...

when such huge hole exists next to a large building, that hole must be well reinforced (which apparent it did). If not, the water pressure coming from river/sea is strong enough to move the land (the whole area between the sea and the hole) horizontally inward. It would dislocate any building foundation along the way. This force is not strong enough to make the building collapse right away, but rather a slow and long process. Making the tower lean toward one direction due step 1) the water pressure force pushing the parameter reinforcement wall of Jin Mao; step 2) dislocate the absolute position of the whole parameter wall; 3) slowing shifting the flloor slab of the basement floor as the results; 4) additional horizontal force for structural columns around the basement area caused by shifting of floor slab and the whole parameter wall; 5) Possible bending of major structural columns; 6) uneven distribution of downward pressure (coz of the weight of the tower) onto the foundation mat and piling. 7) off-center sinking of foundation due to uneven of pressure. 8) leaning of tower as the result.
The whole process could take months. (all this is assuming the swfc hole is badly reinforced throughout the time of this process)

Good explanation, vincent. Once horizontal beams are in place, the lateral pressure should ease.

True, with the foundation plate completed it should be fine.

Wish I am in Shanghai the whole time to watch the construction. I won't be there for another few months.
