DUBAI | Burj Khalifah (Burj Dubai) | 828 M / 2,716.5 FT - Pinnacle | 162 FLOORS

[Northwest]

So the uppermost floors are uninhabited, but are still clad with the same curtain wall. Its going to look odd at night, when the random pattern of lights in the windows suddenly stops at level 160, but the appearance of more levels continues up. Or is there some lighting scheme for the empty space up there?

[MapleLeaf]

Interesting queston. This hasn´t come to my mind so far.

[nickkoto]

How will they get the cranes down?

As I understand it, under normal circumstances, some kind of a smaller "special crane" (for my lack of a better term) is usually brought up to the roof, used to disassemble and lower the bigger cranes in pieces, and then what makes that "special crane" special is that it can easily be disassembled in pieces small enough to fit inside an elevator.

But since there aren't any elevators in the top 5th of the Burj, are they going to make some poor schmucks haul that down 40 or 50 flights of stairs to get to the top elevator or have they figured something else out? I imagine that no matter how small a crane can be broken down, there still has to be a tremendous amount of weight involved to handle those bigger cranes.

If nothing else, they may use a helicopter to haul it down piece by piece, but even that would be tricky when flying so close to a structure like that.

[JACKinBeantown]

They could wait until the wind is blowing in the proper direction and toss it off the roof. The sand will cushion the fall.

There is no sand anymore around the Burj Dubai. So your idea FAILS.

Those cranes must probably be extra durable to withstand the winds at that high altitude.

[Aleks]

I think they install a temporary elevator on the side of the facade to bring the small crane down.

[guyinthesky]

As the height of this building is the tallest in the world, and no crane has obviously been removed from these heights before...If I had to guess, I would assume a "crane" helicopter will be used to remove the Tower Cranes as the easiest least time consuming method...I've known to be wrong a time or two though so you never know!

Hi all.

Crane dismantling plan.

The plan is (was) to have 1 crane up top and the 1 that is there now at L99.

Set up a small recovery crane up top - probably on the platform at L159 that has been there for a while now.

Self lower the main crane to the bottom of its mast.

Dismantle and lower the main crane with the recovery crane to L99 - use the crane at L99 to lower to the ground.

Dismantle the recovery crane by hand and take it down to L99 in internal elevators (one goes up to L160) - set it up there.

Dismantle the crane at L99 and lower it to the ground with the recovery crane.

Dismantle the recovery crane by hand and take it to the ground in internal elevators.

There is no plans to use helicopters for any part of the construction of this structure.

Anyone know what the bars / pipes are for ?

[Dequal]

Just decoration I guess. Or for protection of I don't know what.

[Jonovision]

Could they maybe be window shades?

[Lt. Washburn]

Maybe it's some kind of heat exchanger?

[Dequal]

It's possible but I don't think they would do that. Filling those pipes to get hot water? I don't think so :p

[drewmandan]

To me it looks like part of the eventual window cleaning apparatus.

[Aleks]

Most likely there is no other purpose than to decorate the crown of each setback.

Well i heard the crane will actually be built into the building!
The internal maintenance stairwell for the top floors will use the components.

The cranes are on the outside of the structure. The plans and prints I have show the stairwells and they are not remnants of the cranes.

The cranes will be disassembled and taken down. See my post a page or two back for the planned proceedure.

There's going to be a Chinese laundry on the 165th floor (cheap rent since there's no elevator and thinner air up there) - they walk down to the setback and hang the laundry to dry on those pipes - it's an effort to use natural resources, save energy and reduce global warming...:tup:

Hi all.

Here is a shot of a detail print showing the construction sequence for sections 22A and 22B - the second and third section of tier 22.

http://i34.tinypic.com/2s1ocvr.jpg

We can see that the plan is to erect tiers 21 and 22 before they start the jacking proceedure. So 4 more sections after the one they are working on now - unless they have changed the plan of course.

Should be interesting.

Burj Dubai, the tallest building in world, now even taller

DAILY NEWS STAFF
Wednesday, September 3rd 2008, 4:44 PM

DUBAI - The tallest building in the world got taller - and it's still growing. The Burj Dubai (http://www.nydailynews.com/topics/Burj+Dubai)tower in Dubai (http://www.nydailynews.com/topics/Dubai)is now 2,257 feet tall, developer Emaar announced Tuesday. The highest skyscraper in the world now has 160 stories.

PHOTO GALLERY: WORLD'S TALLEST BUILDINGS (http://www.nydailynews.com/money/galleries/worlds_tallest_buildings/worlds_tallest_buildings.html)

Burj Dubai is still under construction. It was started in 2004 and is scheduled to be finished in September 2009.

In April 2007, Burj Dubai reached 1,553 feet, moving it past Taiwan's Taipei 101 (http://www.nydailynews.com/topics/Taipei+101) tower to become the tallest building in the world.
In April 2008, Burj Dubai became the tallest man-made structure on Earth when Emaar announced that it was higher than the 2,063-foot KVLY-TV mast in North Dakota.

Burj Dubai was supposed to be completed by the end of 2008, but in June, Emaar said that "finishing touches" had delayed finishing the project until next year.

Many of Dubai's building projects are facing delays because all the construction going on there has resulted in shortages of skilled labor and building materials.

Emaar is keeping Burj Dubai's eventual height a closely-guarded secret, but speculation is that it will end up at 900 meters, which is equivalent to 2,953 feet.

[Starsky]

The Dubai tower is really skinny at the top, but still very impressive. Also. 2900+ feet, how tall is that without the spire?

[Complex01]

Wow just amazing. To see it in person would be something else. A sight to be seen thats for sure...

:yes:

[Fury]

Hi all.

The BD will be 818.0 m. high - NOT 900.

When completed the CTBUH may measure it at 825.1 m. The plans say 818 but the handrail on top and the Concourse level may be included.

The spire starts at 700.9 m. in the plans. This is the start of tier 22 and we are on section 21A right now.

In a few days (or less) when the first column of section 21B goes up we will break the 700 meter mark - another milestone for this amazing structure.

:cheers:

[Cypherus]

The fact that this tower has 450 feet to go is still mind boggling.

[Nicko999]

This thing is getting ridiculuosly tall! But I like it:tup:

[CGII]

This thing totally doesn't soar like I thought it would. Now before you all jump down my throat, I'd like to state that I love this building and everything, but it just doesn't have the mass that really makes me stare up at it and go 'damn!' like a shorter, but bulkier Sears Tower does. But it's still a fucking impressive structure.

[jbettcher]

Well I think you'd have to see it in person before you could really back that claim up, but I know what you mean tall and massive buildings really do have an important presence. But just looking at pics probably doesn't sum up the presence this building has.

[ady26]

Hard to watch, but nice!

[[SP]Neo]

great pictures imre. the railings of the setbacks are looking very nice.

[2-TOWERS]

it is a great and very tall structure , but it isn't in your face like the once mighty TWIN TOWERS were . and it is a shame to have 40 floors of empty space.

[Lecom]

Neo;3750009']yes, but you don't have elevators to the highest fake floors. and i think not many tourists would pay for climbing up thousands of stairs...

Well, the obs deck isn't even close to the highest occupied floor. Sure the 125th (or whatever) level is spacious enough to accomodate a decent-size obs deck, but they could've easily made the 162nd level as the additional smaller deck that would accomodate far less people and come at an extra charge, a la the Skydeck at CN Tower and the ESB's 102nd floor.

[Cypherus]

One reason why it doesn't look extremely tall staring up from the base, is the fact that no building is adjacent to the Burj Dubai which gives a sense of relative height. On the other hand, a multitude of buildings are beside the Sears tower and former WTC, which gives relative sense of comparative height.

[zagreb]

next steel section has started, the buildings height has passed 700 meters.

CNN Report on Quake
http://newsimg.bbc.co.uk/media/images/45004000/gif/_45004466_iranquake_abbas.gif


(CNN) -- A strong earthquake measuring 6.1 in magnitude struck southern Iran on Wednesday, according to a preliminary report from the U.S. Geological Survey.

The epicenter was located about 55 km (35 miles) west-southwest of Bandar e-Abbas, Iran -- which is just across the narrow Strait of Hormuz from Oman.

The tremor could also be felt in Dubai, where CNN staff members said they felt the building they were in shake for about 15 to 20 seconds.

"From my office window at the Dubai Media City where all foreign media are located, I can see that a lot of offices have evacuated buildings," CNN Dubai Bureau Chief Samson Desta said.

"I can see up to perhaps 200 people who have taken refuge out in the streets, causing somewhat of a traffic jam."

There are concerns in Dubai, where there are a lot of high-rise buildings.

[NYC4Life]

Someday, the Burj Dubai will be put under a bigger test.

[malec]

Fury, what's the roof height?

[Fury]

Hi Malec.

Tiers 19 to 22 are named roof 1 to 4 respectively.

The top of each of those :

tier 19 - 662.5 m.

tier 20 - 681.7 m.

tier 21 - 700.9 m.

tier 22 - 720.1 m.

So I would say officially by the plans 720.1 m. but;

- The highest level people will actually work in (boutique office) is level 154 and its "roof" is 579.3 m.

- The highest named level is 160 mezz. 3 and its "roof" is 630.5 m.

Good find.

[AltinD]

808? I thought it was just 705 meters tall ...

[Dequal]

And I thought it was 815m? But whatever, these heights are pure speculation. Nothing is official, so we'll have to wait it until official topped out.

[jbettcher]

808? I thought it was just 705 meters tall ...

I hope that's sarcastic lol. Cause they'd have to cap it right now being that the most recent floor added brings it just over 700m tall.

[Lt. Washburn]

How does one know if they lie? I'm not saying they would. But if someone built a big tower and said it was 1000m tall...how could you check that? Lasers? Hold a 1000m stick next to it?

[Fabb]

Compare the size of its shadow to that of another building ?

[Cypherus]

Then parallax becomes an issue.

[AltinD]

I hope that's sarcastic lol. Cause they'd have to cap it right now being that the most recent floor added brings it just over 700m tall.

Yeah I was being sarcastic (and any regular SSC poster would had have no doubts about) because design plans that a number of us have got the chance to see, have clearly stated an architecture height of 818 meters on top of pinnacle.

Not only that but the plans also state that the height figures mentioned, are calculated from 11.5 meters above the Dubai Municipality Datum, which basically shows what's officially considered the ground level at the site. Then there's the guardrail and the light beacon on top that ads 1.1 meters to the final height, figure recognisable also by CTBHU. And then we have the from-time-to-time talk by EMAAR about height increase (the 818 meter figure is from summer 2006 plans).

Well, you get the idea ...

[Bergenser]

^Do you think it's possible that it will end up over 850m?

[br.reese]

How tall is the spire by itsef?
