The top part steel supplying contract was won by Arcelor/Mital but since they don't produce in their factories the kind of sections needed for Burj Dubai, they subcontracted the job to Eversendai in Germany which will cut the sections as for the specification from the steel plates and tubes produced by their South Korean subsidiary.

I just wanted to specify that the Swiss company, which supplied also the cladding for London's Swiss Re building, did went bancrupt before the cladding test failed (some local investors saved the Schmidt operation in UAE), so the two things are not related however I'm sure if Schmidt would have been standing (financially) after the failed test, Emaar would have given them another chance.

Its probably going to be quite a bit less. Since i expect them to instal a hybrid mass damper which is a smaller fraction of the weight of a tuned mass damper, such as used in taipee 101.

hybrid mass dampers are highly suitable to reduce a wide spectrum of induced vibrations, like wind gusts.

if you are interested search for this paper explaining somethings on the subject.

hmmmnnn... looks like the cladding is the center of attention for now. just some thoughts:

1. while it's true that the swiss company was bankrupt even before the start of the job for bd. they have a joint venture with Arabian Aluminum a subsidiary of Al Ghurair which is practically own by EMAAR. So money is not a problem, However, the old JV under bidded the job. the JV are losing 40million DHS in the beginning.

2. So many chances were given to that Swiss Co for your info. 8 times failures in 2 1/2 years. Thats a lot of time wasted. and its going nowhere.

3. The chinese company did it in 2 1/2 months. started the design in Jan 2007 and succesfully passed the 4 combined mockup test in middle of march.

4. The swiss supporters claimed that china aint the same as condition in dubai, so after the initial 10 units were installed, another full mockup test was conducted in Dubai, the same facility where the old cladding design was tested (it was shown in discovery channel). ALAS! detractors were shut up. not a tear drop of water was found inside! NEVER in History of cladding testing.

5. Cladding cost now 2x the old price. even more. so its not the money after all its the PRIDE of the owners that matters. Since they were the joke of the town. "The tallest naked blg"

6. it was once mentioned here that cladding could start at 5 different levels. the cladding was redesigned sush that they can practically start above the 5 mechanical floors. So this means they can be 5x faster than what others think.

7. Since the start of cladding installation last June, we can assume that the chinese have mastered the learning curve so that means they can install even faster as time passes by. But the biggest problem now is that those trained workers cant just bear the heat, so half of them went home to china already. So expect the slow down every 3 months.

8. it was asked before why did they start at 19F? there was a contractual battle since the old JV claimed that they passed the 1st mock up test (shown in the DC). so they insist to install the cladding from 5-17F pending succesful test again in Europe to be done simultaneously while the chinese is doing a test in china. Nothing was heard... maybe the obvious happens.

if you noticed the old steel brackets was intalled already and infact was adopted by the new JV. Anyway for the upper floors it's gonna be aluminium as structural problems occurs for the high spots (higher winloads zones and bigger units)

9. For the record the swiss company was used to be a JV of al abbar when they do the 7 star hotel Burj Al Arab. They were kicked off in the middle of the job.. tsk tsk tsk.

10. The podium cladding works for BD is subcontracted by Al Abbar the biggest cladding contractor in the ME UAE. They were recommended by PM to be be kicked off BD and be replaced by the chinese. But due to face saving issues, they are still on board.... What can you do AL ABBAR is AL ABBAR... as in the chairman.

Thanks! Im now working for the New Doha Airport and Eversendai is making the steel for the NDIA in their Sharjah plant. Funny how in the end a South Korean plant is going to manufacture the steel segments. Maybe a big Korean lobby around?! hehe

It's just speculation at this point ... even that there will be one to begin with.

Good progress on the cladding. Doesn't need to be any faster than 100/day as it'll still be on schuedule. By the way, does anybody know any Burj Dubai apartments are availabe somewhere in the second hand market?

Also, could anybody care to write in short how a hybrid mass damper works?

Yes, mine was 612,000 when first released in August 2006, I bought mine from the reseller 2 months ago for 767,400.

I've seen a slightly smaller apartment 4 floors below me now going for 1,240,000.

I'm guessing mine will at least treble again before the building is completed.

I was wondering that as well. I don't remember another time when so many skyscrapers have been going up at once.

Then you obviously aren't 80-90 years old and from New York.
