How come they dont use drywall and 2 by 4's for all the intertior walls? It looks like they use cement blocks which must be very heavy, no? Here in the USA most walls are with this drywall material, held together with wooden stringers.

You have to remember that Dubai is a hot country so cement is preffered to keep the place cool. In Northern US, the affect is opposite where they want to keep the place warm.

That could be true, but still seems kind of overkill given the efficiency of modern air conditioning. I think in Texas and California they also use drywall for walls. I would guestimate that 5-10% of the weight of this tower is just in all those cement blocks!

California and Texas are not that hot compared to Dubai and Middle East.

i don't know but for me the interior walls look like they're made out off ytong-stones

I'm guessing the walls help support the structure. Maybe I'm wrong about this if anyone would like to correct me.

UK TV Footage

Hey guys, I think you should look at the youtube video here:

http://www.youtube.com/watch?v=RSbK_118YEI

This is part of a promotional segment from a UK channel (Channel 4), that has run a fantastic series of computer generated effects that show a varied selection of scenes that eventually, when angled in a certain way, shape the logo of the channel (a stylised number '4'). The most recent addition to this series is from the Burj Dubai site, in which a helicopter revolves around the surrounding construction sites.

Watch it to the end to see the special shape. ;-)

Channel 4 in the UK do a lot of things like that.

Its the 1st time i've seen that 1 thought. I had to watch it twice to see the number 4 properly.

sorry but i haven't read the whole 150 pages of this thread if its answered more than a thousand times
well the original official height a couple of years ago was 705m. Its since gone up to between 750-800m. Then we come across plans showing height of 808m and recently more plans show pinnacle height of 818m.Also there has been speculation of 900m and up to 1000m.
The 818m height s is what we seem to be going with currently. that doesnt mean it will be eventual height.could go up or down again.
current height is lev135/488m. The core will rise another 30 or so floors to approx 600m where concrete should top out.This in turn will give us a good indication what height the Burj Dubai may be built to.

I would venture a guess that the only place they are using cement block walls are in places they need shear walls. A shear wall is a wall that resists shear forces on the building as a whole. Wind loads are a primary cause of shear forces, and shear wall stiffen the structure to resist those. You want the building to be flexible, but not sway in the wind like a flagpole.

For the majority of interior walls they will most certainly use drywall, and probably steel studs. Most commercial applications these days have gone to steel studs, especially when dead load is an issue.

I would guess you are right about that one. Cement block walls everywhere would be way to heavy I'd think.

BTW, it's not much coooler here in Dallas when you factor in humidity & the heat index that results. Being originally from NM and having experienced the desert's dry heat, I know it's much easier to stand than the humid variety.

That the 1st time i've seen figures for 1039m and certainly 700m of concrete. So evidence please or are you just hoping?
Oh come on, we've already had this debate, and concluded we really do not know what the height will be. It could be 700m, could be 808, or even 1011.

I'm hoping for that 1km+ level though!

^ i agree. 818m is pushing its already proportionate frame. hate to say it but if it goes to 900m/1000m it will look like its been extended, so it could reach that high instead of being designed properly and in proportion, like original design.

drywall is cardboard and is complete rubbish, I fell through a wall made of drywall once -_-, imagine that on the 101st floor......
