As he already said, it depends on the ground. If you would build a 600 tower in the netherlands it will sink into the ground like standing on a piece of butter Unless the foundation is one enormous block of concrete reaching 30 metres deep or something.

Does this, or jin mao or WFC have direct links to subway stations or do workers have to walk overground still to pudong station?

30 meters deep foundation for a 600 meters tower would be enough only if the tower is build over a solid rocky terrain

Like imagine you are in a wet dough what You do is take a huge hard cubiod shaped bread peice and place it on the wet dough and then puncture this bread peice with poles and use those as the load bearers on which you build the buildings . Incase of pudong it just takes lot more work to get teh foundation right say when compared to a place like shenyang of tianjin so it would take a while before the foundation is done . Lets behonest this si a 630 metre building the foundation has to be insanely strong.
Is that for real? They plan on building a 600m tall building on top of soil with a bearing capacity of 80kPa? Crazy stuff. Does anyone know who the civil, structural & geotechnical engineers are? I would be interested to know the details of this foundation. Is there anything hard below the soft pudong soil?

Here guys, in the past post I explained the foundation construction.

Once they build the wall, they can pump the water out of the hole and start digging.

Yes, The Engineer, I noticed, they removed all China construction movies from youtube. Interestingly construction movies from other regions, like Japan, work fine.

There are no underground links between the Metro station serving this area (Lujiazui, NOT Pudong) and any of the surrounding highrises, and I don't know if there are any plans to connect them directly in the future.

"Connected to Subway Route 14 and the other two skyscrapers [Jin Mao & SWFC], the building [Shanghai Center] will have two levels for commercial activities and three levels for parking. According to the developer, the underground space underneath Huayuan Shiqiao Road and Dongtai Road will be fully developed to connect the Shanghai Center with the Jinmao Building and the World Financial Center, as well as the planned Subway Route 14."

Still slurry wall staff on the edges of the circle. You can also see a lot of slurry wall reinforcement laying on the ground. I thing they couldn't dig yet.

shanghai is on the verge of becoming the best skyline i think... they have a few very definitive structures filled in with some very nice mid to high rises that set the skyline off
