It should be about the same as Burj Dubai/Khalifa with concrete pumping.

Quote:
Multiple attributes of the Burj Dubai make this project one-of-a-kind:
•Only high compressive strength concrete mixtures are being used on this project.
•Pours are only done at night because of the hot temperatures during the day.
•Concrete is chilled in the concrete plant prior to preparation and part of the water is replaced
with shards of ice, which allows the concrete to be transferred at 82°F (28°C) (night-time temperatures in Dubai usually reach 104°) to the project site.
•Each batch of concrete is monitored and logged in the plant; before transferring the concrete to the pumps, the temperature and flowability are checked regularly; sample cubes of the batches are poured to check pressure.
•Putzmeister engineers developed a unique delivery line system where the line’s wear behavior, its compressive strength and routing throughout the structure was considered.
•The 75,347 ft2 (7,000m2) base plate of the structure was placed by numerous Putzmeister boom pumps. The foundation is supported by 200, 5-ft (1.5m) diameter concrete piles for the core tower and 650 concrete piles for the tower’s wing sections.
•Three of the trailer pump delivery lines were connected to the three MX 28-4 T Putzmeister placing booms, which were secured on platforms of an auto-climbing formwork and stood on 52-foot high (16m) tubular columns for the structure’s wing sections.

Probably a mechanical floor. These are higher than normal floors.

That is level 15 (and either 15M or 16 as well). The section drawing we have shows this and the next are taller (probably) mechanical levels.

The drawing shows that a small part of this level has a level or mezzanine that may or may not be named but is counted to get to level 20 that is labeled.

I see they are putting labels near the middle of the structure as well. We can see levels 6 and 7 above 4M. We can count up to the taller level 15 from there.

actually some strange things sometimes happening during the construction of KT... For example - they wanted to install tower crane many weeks ago, they started, attach few section and put them dawn again. About floor tags a week ago - we could see B1M and L2M tags, then they has been removed... Wtf is this? It isnt paper model in elementary school , its a very complicated engineering structure and all issues should be solved very carefully. But wee see some troubles - dispute among construction management?

Mayby, but i don't mind as far as the construction will continue hopefully with more speed in the next weeks or months. To see this tower on hold would be bad.

I think we are talking about this floor:






That means, the next one should be as high as this one; and I think this is the reason of the delay of the latest floors.

I believe you are all right (Level 15M/16 sounds right )!

This is the thing I have been confusing the lot of you about over the past 3 months, whether level 16 is going to be poured or not at some point.

I believe that they are going to install three floors of panels vertically over these two taller structural floors vertically retrospectively, for aesthetic reasons (i.e. irregular cladding heights on a simple facade - it just will not work!).

Diagram coming soonish, slightly busy ATM.

Kingdom Tower current height = 78.27m / 256.78ft
Kingdom Tower current total height = 85.86m/ 281.68ft
(includes basements)

Casting level 18; rebar preparation for level 19 on the main core concrete structure.
