What's so confusing? My post makes perfect sense, unless you can provide me with a quote from him where he said that the height is definitely not 808.

Hollie, you and I have a simple difference of opinion on how tall BD may get. No intention to call you any names over just a building. With the cynic and comedian thing, just responding to the slug joke. Please don't take it in an offensive way. Take it as a mere funny response to a funny statement.

For me there is much reason to believe that this thing will reach higher than that 808m figure. The truth will be proven conclusively when the the building reaches the final height. The truth of the actual height will then be known to everybody be it 800m or 1000m or anywhere in between.

accually i measured on my screen, theres a difference of 1.1666... so if the shorter render is 700m then the second is 817m. But if the taller render is 808m then the shorter one is 692m. so its close enough to call the short one 700m, and the tall one 808m!

But I do agree that the second render is 750m, but definetely not 808m, im sure just look at the top of the 808m render.

I think the flat roof indicates that it's NOT the 808 render.

I follow this thread with lots of interest.
I hear a lot about pumping concrete to the top of this structure. There I'm not an building engineer I have a question about this.
If you pump concrete to the top (currently 446 mtr) how much concrete is lost every cycle pouring a level. They pump it through a tube with a certain diameter. If you calculate the amount of concrete needed to fill this tube before the first cubic meter is coming out, it is a lot.
So if the level is poured, what are they doing with the concrete in the tubings.
If they are going to dump it, they will spill an enormous amount of concrete when the building is finished.
Who can give me an answer on this.

Thank you in advance

To pump concrete up high levels like in the 400+ meters, you need a lot of pressure to raise the concrete up high. The risk your taking is that Concrete has to be delievered fresh and durable up top, so that means that you have to minimize the time it takes for concrete to be pumped to the top. If the cycle stops, the concrete may stiffen making the pipe extremely difficult to work with; and of course the concrete is not durable.

The concrete has to be continuously maintained in the tubes so that it does not dry, and the concrete type used stiffens quicker than conventional concrete; therefore, the time you need to build the next level and the current level does not affect the quality or durablity of the concrete used. Of course tons and tons of concrete is used to make the Burj. I would assume a very effient hydraulic system must be put in place to make it happen.

I hope it helps.

when tier 11 (level 124) is completed it will hold the second concrete pump from which they will be able to pump it up higher.

Why so much debate over the height? Just wait till it's completed, no matter what it's going to be the tallest.

Concrete sets via a chemical reaction not by drying. I'd also be interested to see what they do with the concrete that simply fills the pipework to the area being poured. I know in the case of small concrete pumps they pump water through to purge the concrete and clean the pipework. They may do a similar thing here.
