No building for that matter is going to be that wide at that height though; not even these proposed monstrosities that are supposed to be a mile high.. The twins were still built pretty strong though considering even its shortcomings....

This is something that they just cant say for sure, but they can speculate a lot on and give educated guesses based on statistics and other figures....
The Pentagon was concrete and it collapsed in the area hit by a smaller 757 so I am sure BD would be a total loss if hit by a wide body 767 at 500mph like the WTC. It's amazing how clueless people are when they think any supertall would take a hit like that without being destroyed. A concrete exit ramp in the San Francisco Bay area collapsed when a tanker truck crashed and burned at 40mph this past year.

Stunning! It seems like yesterday this tower haven't started groundbreaking and now it's almost complete. Really fast

i agree BD would have substantial damage if a plane hit 3/4 way up but it wouldnt collapse like the WTC did. totally dif structure. wtc was external steel frame with floor plates like pancakes.Steel skyscrapers arent one entity like a total concrete skyscraper is.
sorry to harp on a morbid subject. delete if yu want

Well chillers and AHU's can be paced in mechanical floors, but the actual cooling towers have to be outdoors. I don't picture them being on the roof in this particular case, but that's generally where they put them... Wonder if they'll just use the top of their parking decks for the cooling towers.

Gosh I can't even begin to imagine how massive their parking decks are going to be.

Terrorism aside, do you guys know what they're doing as far as life safety systems and evacuation routes? Is it just good ol' stairwells or do they have something more fancy and innovative in mind?

If it is stairwells, I'd hate to be the one trying to coordinate a fire drill. I can imagine the calls I'd get from the tenants...

"Yeah, the alarms are going off on our floor... is this a real emergency?"

"No sir, it's just a fire drill, but we would appreciate your participation."

"Well... we would... but we're on the top floor, I think we'll stay put."

In Chicago we evacuate down 2 floors, practiced once or twice a year (office building). A Fire Dept official rates our evacuation team and gives pointers.

and i've been yapping about sustainability. for once, a sensible point about the intents of these supertalls. how is the heating and cooling to be done? are the lifts to be solar powered? how much power will the building itself generate?

This tower uses district cooling.

Once again: compare the sustainability of this tower with the combined one of 500 separate suburbian-type homes.

This can't be repeated enough. Sure, highrises are expensive to build, but from an environmental standpoint they are MUCH more benign than a huge slough of single dwelling homes. Imagine if someone argued that buses are bad for the environment because they consume more fuel than a car. Sure this is true, but a bus carries 20 cars worth of people. In the same way, a high rise takes more energy, land and resources than one house, but far less than it would for the number of houses it replaces.

Hi all.

Here is a detail print of the top of the tower.



We can see the 1.2 meter dia. tier 30 pinnacle and the 1.5 meter dia. platform on top. We can also see where the lights connect .400 meters above the platform. We can also see the guardrail 1.1 meters above the 818.0 platform. This 1.1 meters probably won't be counted in the official height. Just as the official height will be measured from the ground and not from the slab 15.25 meters below that.

Just imagine how awesome it would be to be standing out on that platform holding on to that guardrail taking in the view !

Awesome.

Enjoy.

Here it is, its old, and low quality, but good enough. I trimed it down, originally an hour long.

Dubai: Pursuit of Happiness

Its a good one, Project manager Greg is in it. Also documents a Pakistanian worker, on topic with the current buzz about them. He does say he makes 16 times more in Dubai.

Yes that is the foundation of Burj Dubai under construction!
