Thats just quantity, Burj Dubai is quality and it is a engineering marvel.

Recently I have heard of the supertall project of Jeddah- A Mile High Tower and i m worry about the Dubai projects cause it really effecrts the Gliterness of The city.....suddenly there is tower that is twice of the present and half high of the Al Burj ....so in a single shot one will carry the all credit of the height and hype game.....is the game is over or the last hero to come......

I wouldn't worry about it to much, Burj Dubai looks way better than this one. A article on it is accually located in a link on jogiba post which i have quoted just before so take a look.

How have the elevators been designed into this? I take it there is not a single path all the way to the top floor. Will you have to take two or three sepearte elevators? Which floors do they go from / to? Are they of any special design? Also, is there a single stairwell all the way up, or is that staggered too?

not sure about stairwells, but longest lift run is to lev139 or 514m. obviously there is a straight run up lev124 ob deck. there is also lifts from lev139-162. above this is stairwell time.
most elevators will be worlds fastest and double decker.

Any inovations in the elevators like pressurisation or vaccum shafts? Any idea how fast the elevators will ascend / descend or is it too early for these sorts of details?

I both agree and disagree - you could say if it wasn't for the vision of architects, there wouldn't be any work for structural engineers. There are architects who are little more than glorified graphic artists and there are architects - like Foster - who study and understand structure intimately. And then there are those few - like Santiago Calatrava - who are trained in both disciplines. Many of the great architects of classical times were also engineers too.

I studied architecture for a while, before moving on to other things, and I could not understand how you could design a building without understanding the structure. And I sure as hell knew what a bending moment diagram was, and how to calculate it - including graphically! I honestly think most good architects at least can understand structures and make good design decisions accordingly - ideally whilst talking to structural engineers.

Which is not to take away from what engineers do - but at the end of the day what the public *sees* is architecture, not engineering, very often. Which is sad, imo, because I love engineering passionately. Where engineering becomes more visible is in things like bridges which are much more overtly 'structural'. But that's life.

Good comments. Certainly in times prior to the last century or so, an 'architect' was effectively an achitect and structural engineer combined. The two professions have split to allow each to become more specialised and - in theory - to be better at what they do! I agree about bridges being inherently 'engineering' structures. I feel the same way about tall buildings - their design is driven by the structural engineering requirements. The HEIGHT of the Burj is clearly a function of brilliant engineering, rather than brilliant architecture. And it is really the height of the Burj that is its primary characteristic. As for the 'vision' to build it, well that just comes down to economics, rather than anyone's cleverness.

I think the 'desert flower' explanation with the Burj is amusing - the design is clearly to optimise the structure and the idea of it looking like a flower is an afterthought concocted by the architect in order to appear to have some control over it!

I agree about the few architects you've mentioned. Foster's 'Gherkin' in London is my favourite building in the world - it is a perfect blend of architecture and structure. However, in my working life, I have met very few architects who have even the slightest understanding of structural engineering. Maybe 1 in 20 can grasp even the most basic concepts of structure. The few you mention are very special.

The Burj looks fantastic - I think the architect has done a good job of taking a clever structural design and making it look quite stunning.

It's hard to appreciate the enormity of this tower. I mean imagine it in NYC, it's off the scale!

All of a sudden, all skyscrapers and highrises in Manhattan wouldn't look nearly as tall as they do now.

I second that. It would put its size into perspective.

If you look at it vertically, each tier appears to be 'layered' onto the taller one right next to it. That wasn't apparent with the building's structure before the cladding went on.
