Why is the steel construction going so blasted slow? Does anyone know?

I think AltinD summed it up very nicely on another forum:

"- difficulties related to the first floors that require a much much higher precision then the upper floors

- more controls and tests related to the materials

- more difficulties to work in such heights.

Anyway the first floors are always slower then the others, even when you are at ground level."

OK, thanks Burj. Appreciate it.

The first steel stage is 157?
I´m not sure. (Look to the written number 154 http://www.burjdubaiskyscraper.com/2008/01January/Burj_Dubai011714.jpg )

They have probably had fit up problems between the steel and the concrete core. That's a complicated steel structure and they have probably had more fit-up problems between steel members to get to where they are now. A steel erection crew is broken down inti two teams , the erectors who climb on the steel and postion/secure the steel in place with a few bolts and the bolting crew that follows to complete all bolting and bolt tightening.In this case , I don't think that the erecting crew can get too far ahead of the bolting crew, for a number of reasons. This steel has to be placed in the exact postion or they will be in deep trouble farther up. In a high rise building say 40 to 50 floors ( 150 m) and simple framing) a steel erecting crew can place 40 to 50 pieces per day. They are presently at 600 m , on a small floor plate and tying to place complicated heavy steel framing .A couple of pieces a day , maybe. This should get interesting .

Has anyone seen or heard something about the window-washing equipment?
According Emaar's website, it should consist of 3 telecoping machines. I assume they will be (were already ?) placed on floor 156.
Does anybody know?

Concerning the speed of steel erection: I agree with Schrodinger's Cat: a complicated construction on a realtively small surface, at a tremendous height, etc. etc.

I'm waiting for the first pictures from up above...

Two new photos by OTR of the steel section, still at second floor (?!):

They are still at the very beginning of the steel structure.
