It's a nice change to see the Burj without the formwork, it gives a slightly more representative impression of what the tower will look like upon completion. Without all those bulky forms and scaffolding bulging off the top of the concrete part of the structure the straight lines of the core are easier to distinguish from bottom to top. It looks more graceful now than before, to me anyway.

helghast. theres no setback above lev155 because it hasnt been built yet. as soon as steel framing starts up you will see new setback.

brainic-it does start to get thin at 586m but you cant compare to other talls beacuse theres no other skyscraper within 100m of its height.
at 450m high BurjD is about 45m wide, which is approx width of the massive sears towers top.

Hey Helghast.

The setback is going to be on the side you can,t see in those shots. also it still has the formwork on it. The setback will face approx. 60 degrees and the Dubai mall. The setback is after the levels that are poured now. It will show after the steel begins to rise as I and others have said before.
This screenshot from the Burj Presentation shows it best.



You seem to be quick to try to prove people wrong. While I too hope they change the plan to the taller I don't think they will now with all the plan changes they've made already. Never know though - we will have to wait and see.

Be patient - all will be revealed soon.



LOL - beat me to the punch Cul.
This is such a cool time in the construction of this structure. Now we can see the steel anchor points. The next few days and weeks will be great to see. Hell who's kidding who - the whole thing has been and will be great to watch. With all the great photogs and the net it is like we are all there. Awesome.

Well, looks like we now know where this is gonna come from:








I assume we'll soon see them removing the crane sections beneath the brace. Pretty ingenious if you ask me.

(But then again, it doesn't take a whole lot to impress this guy. )

Yes, the attachment to the core looks similar, FTL Beach Bum. But the existing one you show is at about level 153, whereas the attachment for the new crane should be at level 155mez, according to the render. So I'd think that the crane for the top should be fixed to the third face, so that the cranes don't stand in the way of each other during dismantling/raising. Probably all three cranes could work seperately then for a short time.

Still I don't get how the new crane can carry tons of steel, being only vertically attached. Will there be deep holes in the concrete for this, or do some bolts the job sufficiently?

It appears to me, that, in contrast, the existing cranes always stand on top of a tier wing below or continue downwards, so that their attachments only stabilize the crane.

edit: I just saw construction pics of the Guangzhou TV Tower, where the 2 huge cranes stand on small temporary platforms, which are connected to the core, alike the new crane will be. So as has been prove, a crane can be fixed like that. Maybe it's the same for the recent BD cranes... it's difficult to tell from the pics, because there are almost no detailled downviews on Burj Dubai, or the base of the crane is hidden by scaffolding or nets. On Culwulla's diagrams, the cranes don't continue inside the building all the way down, and this would also disturb the completion process of the lower floors. But I have no idea how the cranes have climbed up the core all the time then. ...Can somebody tell me about it?

I am interested if they will wait for all concrete to be completed before continuing with steel. Its not necessary as crane is mounted to the core wall and not to winglets. Also the last uncompleted tier doesnt have effect on what is going on top. Cant wait to see

Why would they remove the frame before inserting the steel? Isn't the frame there for safety?
