Comparing the latest photos to this diagram of the structural model I'd say it is still not topped out. But we don't know how accurate or up-to-date this diagram is...

According this diagram, it seems there really is a bit more to the top.

yes, but it shouldn't take longer than 2 weeks until it's really topped out

I have always wondered what those concrete braces/beams are for thet you can see here very nicely.

So far I have only seen them on Chinese skyscraper constructions in the basements. Other countries don't seem to use that kind of construction, so could anybody tell me more?

I'm not 100% certain, but I believe they are using a special reverse-engineering method to excavate and reinforce these holes. At first they cast a layer of this grid structure, which is usually one large circle with many beams reaching from it. The actual shape is unique for each project and I assume the shape is based on static calculations, taking all mechanic forces (earth pressure) and events (heavy rainfall, frost..) into account.
In step two they start to excavate one underground level, then they cast the walls at the edges of the hole, below the grid structure.
They repeat these steps a few times until the hole has the desired depth. Then they can start with piling / foundation works.

I don't know why this technique is used almost exclusively in China though and some enlightenment would be appreciated.

No idea how good or accurate my description is, and I'm certain some people can explain it a milion times better

i know one thing about it, it makes it a lot easier to connect all the buildings below level.

what do they do when they are in a dense grid already, with no room for the excavation.

At least it already makes much sense, your explanation. Thanks a lot!

At first I thought that it would simply be because they are constructing ssomething like parging garages in the basement that simply covers the whole area contrary to the skyscraper that doesn't. But then again for a simple parking garage you don't need that special shape of conrete beams and you wouldn't pour them before even starting to dig the hole.

At first I thought something like that too, but then again I haven't seen that method in projects outside of China. Outside of China there must be many of those kind of lots too, where yo don't have that much space.

Another initial thought by me was that they do it because of soft soils that makes skyscrapers need a more solid foundation, but that only makes sense if they use that method in a few selected regions and not all across China.

Its not top out but its also not 329m either, when SOM did the final design the roof height they give us is 323.3m last time I checked, still its not topped off

the underground bracing is also for earthquake and annual typhoon proofing, which is nationwide. In most regions of the world you wouldn't need so much extra strength, which is why you see it more in China.

Why does it show the Los Angeles skyline in this render? Kinda incongruous...

- the architectural studio is likely not set in shenzhen
- they likely do not have renderings of several angles for the plot that the building will be set in
- filler background just to have any setting at all in the render as the background isn't important
