Cladding looks much better on the bottom left as opposed to the bottom middle part. Dont you think? i think the middle part looks abit cheap.

Yes, it's the same cladding. The key difference being....the one on the left has its white protective film removed...and the other has it's white coating still on. They are peeling it off in sections.

I am now very confused and would really appreciate some clarification on this matter. Who do I believe? The two guys who live in Dubai? Or the two guys with the plans of the tower?
There is conflicting descriptions from old and new sources. Remember that the building went from 705m to 819m and both designs are still being quoted.
The latest design has "provision" for a Tuned Mass or Tunes Sloshing damper...but no mechanical damper like Taipei 101 as the area is not seismically active.

(My speculation)
I think the reaction of the building on wind must be considerably different when the cladding is complete. At the moment, especially in the upper parts the wind can just blow through the floors. You can see on the helicopter pictures that you can look "through" the floors, there are no massive walls that stop the wind.
Once cladding is done, the building must resist to the full force of the wind, so it should swing alot more then.

considering that this is like the 10th thread about the Burj Dubai, and this one already has 230 pages, you can be sure that was asked before.

Apart from being 0.8m taller than the more common 3.2m high levels....nothing!

However, I am surprised that nobody has yet picked up the fact that L154-L156 are taller than shown on any plan.....which is where the heights now mismatch all diagrams shown on this forum, including the latest ones that I supplied.

The revised spire height changes were approved on November 29th 2006.
On June 27th 2007 further design changes altered L154-L156 heights and many of the steel spire and pinnacle sections raising the overall height by an additional 135m.

A total of 3 height increases since November 2006 as per PMI number's 366, 378 & 517, authorized by KJ Kim of Samsung Corporation, on behalf of Greg Sang on 27th June 2007.

Section A of the steel spire section will now take 358 days to complete, an additional 68 days over the 818m version, expected completion of spire section A on 8th March 2009.

Section B of the steel spire section will now take 313 days to complete, an additional 87 days over the 818m version, expected completion of spire section B on 8th November 2009.

Yes, Spandex I am.
I did post all the original documents on my website about 7 months ago.
I have so much info on it that some of it I'm still reading now.
I posted so much info as I was retrieving it directly from the mainframe in real time, hardly anyone really read it....apart from Fury, who was clever enough to back everything up locally.

Just to point out that this is for the 705m version.
The spire erection methodology now requires two cranes to traverse the tower and raise the pinnacle, not one.
Crane 2 (M2-380D) will rise to Tier 20 at 712.5m
Crane 1 (M1-440D) will rise to 822m with a working boom reach up to 856m.

Which is one of the possibilities I considered due to the second crane still being present atop the beast.

Im still sceptical about it though and will wait for the steel structure to change before I rip all my clothes off and run down the street screaming Eureka

That's also not quite accurate.
The total budget for the Burj Dubai complex is over $12 billion USD. The tower itself was proposed at $3.8 billion, which turned into $4.1 billion USD upon re-design.
With unfactored time extensions, rebar and aluminum cost increases and the cladding already being $850 million instead of the proposed $266 million it was budgeted for...the tower alone is expected to cost over $5 billion USD.

Not plans as in diagrams, internal letters I found on the Burj Dubai's project management mainframe server.
I have only read about 3000 of them so far, I've posted about 400 of the most interesting ones on my website over the last year.
They are official memorandums that were entered into a mainframe database that some naughty monkey kept eluding attempts to stop him from downloading everything including live CCTV footage, GPS data, and internal emails.

Thanks Skytower for your fantastic work and info. It would be cool to see BD go for absolute maximum height. Let us know when Dubaimegaprojects is up and running for more detailed information.

Dettol......let me know when you want to rip your clothes off. I'll be running the other way. Actually if BD reaches over 900m I'll run with you yelling Eureka in stereo.

You're most welcome!


I think maybe I've been misunderstood?
The 135m increase is the 3 stage jump from 705m, not from 818m.
I'm saying the final height will be around 840m...not 954m.
I apologize if it sounded misleading.

First jump - 3rd April 2006 - Rose from the initial designed 705m to 808.4m
Second Jump November - 29th 2006 - Revision to mezzanine layer configuration and L162-164 transition pushed it to 818.0m
Third Jump - 27th June 2007 - Height changes to L154-L156, setback configuration and taller pinnacle pushes it to around 840m

Yes, as far as I know. The exterior is about 3 weeks behind and the interior is about 4 months behind. Should be topped out and fully clad by the end of next year.

Samsung presented this week in a conference held in Dubai, a video showing the spire and pinnacle erection technique to be used. A friend of mine was there to see it, and so was Jan.

I'll meet the guy tomorrow and ask.
