Would be interesting to view more familiar old super talls around it to see just how small they look compared to this! The tallest free standing structure where I am is only 330m, which here looks massive, but there, would be nothing speciel even next to the average building in Dubai lol.

The Burj Dubai doesn't look as impressive as its official heigh. It is because the building has the shape of a thin stick, with gets thinner and thinner in a exponential way. The ESB transmits mass through its structure. If somebody made an 800 meter tall ESB it would look much more impressive than the Burj Dubai, it also would have about 3 times the floor area of the Burj Dubai. Of course, the burj dubai is the most impressive building in the world, and will have the largest floor area, about 50% more than the Sears.

Can you imagine supertalls around the Burj as tall as the Empire State?? It boggles the mind. Shows how far we've come.

What your saying is correct, only thing is; Abraj Al-Bait in Mecca is going to have the largest floor area of any Tower in the world.

But you must admit that the Abraj Al Bait is more like a complex of towers and not a single tower.

Actually, Burj Dubai have a smaller floor area than Sears

Burj Dubai:
Floor area: 334,000 m˛

Sears Tower:
Floor area: 418,064 m˛

so 20% is less than Sears...

Actually the latest post are quite interesting. Lets see:

Shanghai World Financial Center: 377,300 sq m
Sears Tower: 418,064 sq m
Taipei 101: 412,500 sq m
Guangzhou International Finance Center: 448,000 sq m
World Trade Center : 800,000 sq m (1&2)
Burj Dubai : 334,000 sq m

Also:


Many say that Burj dubai is the masterpiece of modern time, the best building etc etc. I actually agree, its amazing. But, I can't help but think what excacly is that makes it engeneering miracle. I actually believe that Sear Tower or better Shanghai World Financial center, WTC, Taipei, are by far greater construction feats. I mean if you look at the cross sections, at 450m, in the later, you can play soccer on the floor plate, yet at that height Burj has less floor space than my house.

Just think along for a minute, isn't Shanghai World financial Center a taller building than Taipei, yes or not? I mean all those criteria about top floor, architectual top, roof top, spire top, they aren't objective enough, I believe that the notion Tallest Building in the world is getting old. We should just let the building's design speak for it self.

You are the one who keeps bringing this back, disrupting the thread.

Wow, the floor areas are very interesting, are there any reliable sources or complete lists about them?

Floor Plate Comparisons - A Reality Check

What needs to be appreciated about the BurJ Dubai vs. those other supertalls is that its inherent design puts more occupants along the curtain walls with a window access so that more people have those amazing views throughout most floors of the structure.

For many working inside Sears Tower and the other 'form follows function' giant rectangular boxes - when they are in their office spaces, usually cubicles under flourescent lights, they might as well be working in a single story building or even underground.

I've been way up inside the working spaces of many of the mombo skyscrapers in Chicago, like the John Hancock Building, and except for the managers and other higher graded employees most of the worker bees don't have any view at all or see much of an aesthetic benefit from taking that long elevator ride each morning.

In many ways the Burg Dubai is just a brilliant design.

My $0.02 worth this am.

We should just let the building's design speak for it self.
what you have to remember is that the burj dubai main function is not office like SWFC, sears tower, wtc, etc. it's main function is residential and hotel. in the WTB records there's never been a Mixed use "tallest building". so where use to huge office and commercial buildings with huge floor space. also if the burj dubai was going to be used mostly for office the design would be totally different. the burj dubai has many tier's as u can see. which obviously reduces floor space which is another reason why there's not as much floor area. the design concept they came up with is very effective against vortices and other windloads. while they were doing wind studies on the buj dubai in the wind tunnels they discovered that if they could increase the steel setion higher, the vortices decreased dramatically. which also was good news to Adrian Smith because he felt that the top did not fit well with the rest of the building. also what you fail to realize is the burj dubai is doing something thats never been done before in the History of WTB's. if you look at the records. every time a title was broken it was only taken under 300ft. i just compared the sears tower to T101. sears was built in 73. T101 was in 04. that was only a height increase by 220ft. then all of the sudden here comes the burj dubai doing something thats never been done before and beat all of the records by not a 100ft taller not 300ft taller but OVER 1,000ft!!! OR over 300m. which has never been done before. and not only that it beats any structure, tallest freestanding structure and any structure in the HISTORY OF ManKind

like Fury's signature say's....
Burj Dubai - The Greatest Structure of our Time !!

I don't care in the least about the intented function of a building, when I compare with what I see. As far as height increase is conserned, its the most objective comparison you can make. As far as I know, Taipei is 200ft taller than Sears, yet it has lower top floor and roof, yet WTC in Shanghai is heigher in both. I have made models of most famous skyscrapers, and I as far as I can see the disrepances are huge. What I pointed out is what everyone hate to admit, and this counts me too: The Burj is the tallest but its not very big, and its actual volume to height ratio is ludicrously small. Residential or not, it puts far less mass in the air than many other supertalls.

Please don't start the hate coments for this observation, I was just reading about measuring standarts and I got over-phislosophical, maybe I should have kept those thoughts to myself.

i agree with both helghast and reiayanami in that, while its unfortunate that the floorspace is lower than most other WTBs in the past half century, the window to capacity ratio is much higher. so i kind of like the design as far as area and amount of windows go. now the nakheel harbour tower, on the other hand, is a totally different story. im curious as to how they will pull that off.

as for your thoughts, Rei, on the measurement controversies, i think most people on SSC including myself would actually agree with you that its retarded. thats why the burj is so great, it beats everyone at everything!

thanks for the diagrams, i hadnt noticed the differences in area before
