Theres great detail in Imre's photos of the cladding fixing.
Its impressive how the fixing channels are pre-cast into the concrete. Explains the speed at which the cladding goes up, half the work is already done

just on the planned observation deck.
most people over past few years have mocked how Burj Dubais ob deck is "only" going to be 442m high on lev124.
but looking at imres pix, yes they are from lev140 which is 508m or 16levels/66m higher then planned ob deck, but gee they look high enough to view Dubai from. Any higher and you will probably start seeing less, due to dust ect.
I think 442m will be perfect.especially out on the open terrace, so you can also view up 400m .

Cul: Two observation decks would be better like the Tokyo Tower has.
What would you see 700m above the ground? You would be above the dust and you could see the mountains.

Ok, thanks CULWULLA.

But you should allow the people to go to the top of the building (no the spire, a 600 meter deck orbeacon could be perfect) paying an extra price like in the CN tower or similar.

I think the main problem people have with the ob deck being at 442m is that it's the only record Burj Dubai needed to break. It seems a little strange to me that this building will be sweeping away all records except ob deck height. I still hope that there will be a smaller ob deck higher up, even if it's only open at certain times, just to see BD break the record.

Sure, I agree, architects do get involved in the contractual and management side of things. But they are also frequently credited with the structural design of buildings and they in fact have no involvement in it. Most architects wouldn't know a bending moment diagram from their left elbow!

Us structural engineers get a little sick of the public giving credit to architects for work that is done by our profession. A tall building stays up because of the work of structural engineers, not the work of architects.

I agree, two would be great. I think some people would love to know what it's like to be 700m in the air while standing on solid ground while being in a city and not on a mountain range nor sitting in an airplane seat. I think some place in the steel section would be ideal with a bar and a restaurant. Just imagine.

I have no doubt that the view from the current obervation deck will be thrilling.... But the view from one at 600 or even 700 metres would be much much much much more thrilling.
The obervation deck now.. yah its high above ground. But still in a scale that people are nearly used to and there are other buildings that reach the same height...

But even now at these about 640.. thats above all imagination people have. These 200 metres more make such a difference.
I think they should have put a more expensive observation deck at the near top... and another one, maybe with a restaurant where it is now. Sth like Windows of the World in former WTC.

thanks for reposting fury. lots of acquired info there.

great seeing 818m mark for pinnacle and then another 1m or so for guardrail. with the hatch to the roof of the world..lol
Any floorplans for the ultimate pinnacle?

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.

I'm not sure if this has been brought up yet, but I'm noticing that with the cladding going on, this building is developing a neat architectural 'layering' effect with all of its tiers, an effect that was not noticeable when it was just the bare concrete structure.

Build on!

Mike
