Never, but never question engineer's judgement

This system seems very similar to Bob Holverson's "braced spined" that will enable the Russia tower to reached extreme heights as well.
Maybe the three-winged approach is the way to go when it comes to designing the supertall buildings.
By the way, does anyone know what is the next tallest building?

Amazing what man has done.
RE: Looking pretty tall
The construction tollernces were a big concern, they went to the extremes to make sure they had it truely vertical. A variation on 1/16" to 1/8" per floor could be a disaster, but concrete allowed corrections to minimize the load and eccentricity effects. The Italians in Pisa were the first to discover the effects, but this tower is not built on muck.
If it is anything like the hotel ($2500/night minimum), I am sure the upgrades are really that since they build show pieces for the international business traveler.
I was in the hotel and would love to see the tower when completed. I also would like to see the indoor ski hill with snow making.

Both. The first 130+ floors are concrete while from 600+m onwards it switched to steel construction. Basically there are problems with pumping concrete to such heights so it was designed to be completed with steel-framing. A friend of mine who was in Dubai recently took a photo of the builders kibbling the last of the concrete pour up to a height of 600m.
If you can get a hold of a high quality photo, you will actually notice there is no scaffolding around the floors underconstruction or the plant levels, all part of the Dubai construction practice of building massive buildings on reclaimed land, let's just hope in 10 years time there will enough people to fill all these hotel rooms under construction. Ski resorts in a desert subject 50C (120F) temperatures just doesn't seem sustainable to me, particulary when you consider the water supply relies on desalination.
Now CCTV in Beijing, there is an engineering masterpiece.
Like Mario Salvadori said, who would go and see the straight tower of pisa.

Their leadership is visionary and they are using their wealth to build their country and its future.
Good for them.
