I think they are often temporary. I believe they are way thicker than your usual floor slab hence wouldn't fit. That is if they are even aligned with the floors because they may be placed solely based on the required support on certain depths (we usually see them closer to each one as they are deeper). I remember shanghai tower rings weren't aligned with the floors, and at least some of them got blown. The same happen at the Goldin Finance construction site. At least one of these huge concrete grids got destroyed when wasn't needed anymore.

The rings were there probably also for reinforcement?

I'm not an expert but I don't think they are needed when floors are poured. Their main purpose is to support hole's walls from collapsing during construction due to the soft soil. Take the lote tower in seoul. They didn't make any concrete rings there because apparently soil conditions didn't require them.

the SSP diagram is still for the 648m though, just add another 10 meters to the spire and it is more like the reality . i don't mind this to be taller than Shanghai Tower, i love both buildings and probably like Ping'an's overall design even more than Shanghai Tower and the size won't even matter for long anyways, the title for China's tallest will go to Shanghai Tower first and then to Ping'an and then to another building in china, it will jump around in very tiny intervals anyway, so i am okay with Ping'an having the title for 2 years or less even if it was kinda cheated.

A matter of taste. The both will be iconic buildings, but i prefer WUHAN Greenland Center, Goldin Finance 117 and Zhongguo Zun (CITIC Plaza)

If you we speak for clusters from tall buildings, situation is changing.

all of them are unique in their way. there is no chinese building over 400m that i do not like, all of the designs are amazing in their own way

It's about time to jump up the cranes. I wonder how they gonna do that. I can't see any climbing cages installed or laying around. I hope they won't gonna dismantle them, add segments then reassemble.

I think you meant to say without the spire, and you are correct, it has a roof at 740 meters, on the other hand its top floor is at 605 meters.

Only which roof?

This is the top roof of the burj at around 828m (+/- 1m)

btw burj isn't the tallest in all categories it doesn't have the tallest observation deck for instance.

There have been several discussions on this. The current theory amongst some folks on the board is that the concrete forms will jump a few more times until it is almost to the top of the existing steel.

Then tower cranes #2 and #4 will be built and attached to the building in climbing rigs, similar to Shanghai tower. See the orange bracing connected to the Core in the image below. That bracing "leap frogs" up the building and pulls the tower crane up to the next level.



Once cranes #2 and #4 are attached, then they could do a couple of different things. I think they will attach climbing rigs around the existing towers, connected to the concrete core, and disconnect the cranes from the base and just move them upward. It is also possible they will have to take them apart and rebuild them in climbing rigs.

Anyway, Probably will be a few weeks for the core to be poured high enough to begin changing crane configuration.

What do you guys mean by "demolishing" the bottom ring??? Why Would they do that?

Because they built new floors around it to support the weight of the site walls. They're becoming useless now, so they're being demolished.

Rings like those are never permanent.

That is possible, but if I'm correct, the cranes are standing on the basement floor at the moment.
