Indeed, it looks like the wing edges are going vertical now.
We have to wait a little longer before we can say for sure.
I can not imagine that it is a dis-formation caused by the camera lens...

CORRECTION:
This image consists of 2 photo shorts, with slightly different perspective.
You van see that by the yellow crane mast, which has a discontinuity at the same height where the wing inclination changes !!!

Great tower but location looks absolutely surreal.

What with the sewers and powerlines and all of this kind of stuff. Is it already in the ground or will it be developed later?

They have roughly 100 floors left to pour, so it would be a quite simple calculation. Each floor requires four formwork jumps (one of the core and one for each of the three wings), making for some 400 jumps in total. If they do two per week, which seems to be the current pace, concrete works will take another four years. Then there would be the construction of the spire, cladding the building, and all the building interior works, which would probably take a couple of years as well. Some of it could be done in parallel with the concrete pouring, however.

So roughly six years at the current pace. Maybe they could get it down to half that if they speed up.

I can not imagine that the mentioned 55 football fields of glass are on the tower itself.
My calculation comes to a little more than half of that:

I assume the base of the tower approx. 120 m, including the curved shape.
So one side has a surface of:
(120x1000)/2= 60.000 m2
(division by 2 because it is a triangle).

The 3 sides thus have a surface of 3x60.000=180.000 m2.

I assume the blind edges of the tower 20 m wide, and average 800 m high:
The 3 edges have a total surface of:
20x800x3=48.000 m2.

The total surface of glass on the tower is then:
180.000+48.000=228.000 m2.

An official football field (soccer) has a surface of:
68x105=7.140 m2.

The amount of football fields of glass on the tower is then:
228.000/7.140=32 football fields.

Off course the above is only a rough calculation, but in no way I get to reach 55 football fields on the tower itself.
I assume the remaining amount will be in the surrounding structures.
But in total, it is indeed enormous !!!

*snip*.

But wouldn't this be doubled because we're not talking about one flat plane? Each side of the tower has two triangular halves. So it should be 6x 60,000 or 360,000 instead. Coupled with the other measurements brings us to 408,000 / 7,140 That makes it to about 57 football fields. More or less on target. The loss we gain from a true triangle above 800 meters is probably offset by the flat areas of the core on each side in the center.

I agree it's still a LOT of glass!

According to the floor directory on Wikipedia, the last core jump brought the tower to a sky lobby at floor 65/66.

He is asking about the infrastructure, basic services like electricity, storm drain, water lines and sewer system, if there's already something done about that.

I think he meant the current height of the tower

The tower must be 258m or 262m now, but i‘m not 100% sure.
