:previous: Im impressed how on top of this stuff you guys are......this building is insane......keep up the good work

[M.K.]

I don't know. I see the reality in this pic more a little bit different to the illustration. As illustration and rendering is much more interesting and harmonic mainly in how spread the terraces are, in reality the distances between the terraces like not that constant and different to the Rendering shows. :sly: Something is wrong there by the playmobils in stage. :previous:
BTW it tooks 2 years to go further only with the structure in half high. It is said only more 2 years to finish all completely. Maybe I am dumm in not making good the summe, because if 2 years were taken only to make half the structure, more 2 years should be taken to finish the structure high. And where is the time to make the most lazying phase of a project, the windows, walls finishing and interiors and exterior??? It should be more 2 years. So I think that tower will delay 2 years, finishing not end 2008, but maybe 2010. Am I wrong?

[kenratboy]

The foundation/site prep is probably the most difficult thing. From here on out, it will be pretty routine (well, for building the tallest building in the world).

[malec]

It will probably be done in 2010. Cladding delays and also design changes are the cause of that

One question Skytower or anybody else.....

If Sears has 108 floors above ground, how many floors underground would it contain?

If BD has 109 floors, I assume the above ground floor count is still 106.

That said....Am I correct or am I missing something.

I believe that the official floor count should be floors from finished ground level. We can call the floors from the raft as total structural floors.

[SkyWatcher]

I agree...floors below shouldn't count as above ground levels. That said, meters/feet are better numbers for comparisons with existing buildings since floors can be different heights.

[vanhenrik]

[January 28th 2007 - Level 109 - Height 406.11m - Currently the 7th tallest highrise building in the world!

Truly amazing

my feling is that it is going faster & saster ! per level

[neverdone]

I have read that they will be switching to steel part way up. Why is that? Weight? Ease/speed of construction?

[MikeM]

You can only pump concrete so high (around 500m) with current technology. Secondly the weight/strength ratio starts to favour steel past a certain height.

[Alliance]

I believe that the official floor count should be floors from finished ground level. We can call the floors from the raft as total structural floors.

This gets tricky though. For example, some of the streets in Chicago are elevated, so buildings lose a lot of footage, because they are not "above ground," even though they are.

If anything, we should not count spires in the official height of the building.

[Scruffy]

and we're back onto the number 1 argument with skyscraper afficionados. Counting or discounting spires. haha


Is the structure of the tower going to be built outwards at all or that it. Cause the skeleton as it is looks "ackward" to say the least. Even with the facade up, i'm not too sure about the final product. It definitely doesn't seem to look like all the renders

109 is the above ground floors! BD has 4 floors below ground not counted in this figure.

Sears is 110 floors and 108 above ground levels

BD is 113 floors and 109 above ground levels :tup:

[SteveD]

I know this has been stated 1,000 times before, but the number of tower cranes visible in that first photo above is absolutely mind boggling. Is this the greatest concentration of tower cranes in human history? If so, will it ever be repeated or are we witnessing something that will never again be repeated?

[SkyWatcher]

Did you see the one on the first page of the thread where there are many more in the same area?

Staggering it is.

[2-TOWERS]

the twin towers were 117 floors,they had 7 floors below street level, and even though the BD will shatter records , probably 4 ever, it still will never have that....'' IN YOUR FACE '' that the TWINS TOWERS had.
BOY I MISS THOSE PAIR:(

[arcite]

If so, will it ever be repeated or are we witnessing something that will never again be repeated?

Is this a trick question? Of course it will be repeated. The sky is the limit.

[SteveD]

Is this a trick question? Of course it will be repeated. The sky is the limit.

No, it was not a trick question. How can you be so sure? I was speculating that the unique conditions giving rise to this unparalled construction boom in Dubai might not ever occur again elsewhere. If you are so sure that it will, maybe you could provide your insight for me (and anyone else wondering).

[SkyWatcher]

I have never seen a building boom this big across the board in my lifetime. That said, I can't say that I never will again. For almost 20 years NOTHING much was built in the Dallas area, now there are cranes everywhere you look. While there are not as many as in the 80's, they are getting close.

As far as Dubai goes, that is unprecendented as far as I know, but Panama City and others are not far behind in scale. To say that it won't happen again would be foolhardy. The way population is growing in the world, we might even get to see another huge boom before we cross into the next world.

As far as the world's tallest goes....oh yeah, there'll be another one and it won't be very long. Unfortunately I have little coinfidence that it will occur here in the states.

[vanhenrik]

you can puymp conconkrete to that level it takes it so harden ! i meeen you can pump it to aprox 1500 meeters but you need e cuple of pumping stations a long the way !

[M.K.]

I think the reason of changing in that high to a steel structure is other, not pumping, as you can pump up as high as you want if you have subpump stations in the middle. The reason is the weight/high/wide relation comparing to the high and as the structure is coming too thin now comparing to the base section favourates to a structure in steel completing the rest. Also the structure now should be more flexible according to how high it is, as the wind requires a more dynamic struture than a solide base so it can move according to the side forces on the stress the all complex, avoiding collapse, because constant side strong wind in that level, the base is more inflexible and moves less, then solid concrete in base to support the weight, steel on the top as less heavy it is and faster to mount, because flexibility.

I still find it hard to believe that this building will/can be as high as they say.
I am just commenting on the height to width ratio. I understand that all of the wings haven't yet caught up to their full height yet, but it just baffles my mind. I mean look at the base of the building, although it is wide, i keep trying to visualise that this building is "reportedly" only halfway built. It seems like the renders - the way it tapers near the top - would have a wider base.

[Beyond 1000]

Again, I would like to ask a REFRESH question to all of you in BD land. Given that they might extend the wings to whatever their full height may be, (or higher), in light of Biff's comments above, does anybody here feel that it is plausible that Burj Dubai can reach the 1,011m height level floating around? I mean here, that even with extensions on the wings and a longer spire, can they actually add 2000 more feet or 610 more meters to what you see above or is it really too late for that?

Thanks

[Sky Tower]

:previous: Although I am kinda biased, there are a few diagrams/renders kicking about that highlight how this can be done quite elegantly, utilizing the current setbacks that mimic the 705m version, which lets face it did end a bit abruptly!

Excluding my contacts, I always independently believed that this building would exceed 840m+, just by understanding the nature of how and why this project was approved in the first place.

This is the building that will put Dubai in the minds of many millions of people as it becomes infamous as a WTB, to highlight what Dubai is set to achieve in it's goals as a 'must go' tourist destination.

This is widely regarded as a money no object construction and I believe that anything and everything is not only possible; but essential with the fluid nature of it's design if the only goal is pure height alone.

Unfortunately, I also believe they may sacrifice a beautiful design just for the sake of going higher, just because they can!

The renders of the 808m model look ergonomically spot on to me, but that's just my opinion!
I just hope they don't spoil the aura of the building just to go that bit higher!

No one yet has mentioned why floor level 96 is 4.5m instead of the 4.2m like all of the other levels either side of it. I thought it strange at the time of the update but you can actually make it out in Imre's last photo's. I have no explanation either! :shrug:

[M.K.]

I don't think there is a possibility to grow more than 807m. The structure is already thin and there is no sense in going too high, as 807m is just too much to be the tallest for years.

[Sky Tower]

Well at it's narrowest at the hight it is currently (when the wings catch up to the core) will still be over 64m wide. Wider than each of the WTC Twin Towers were in New York, and they were 413m tall.

Stick that on top of this building as it stands now and you have an 820m tall building with a flat roof, that can sustain a huge spire!

1000m is definitely achievable!

[Downtown Bolivar]

I think the issue is that this building has climbed so high that the scale makes the top of it look freakishly thin!

[Dac150]

How thin the upper floors of this building are going to be is ridiculous. The building is really cheating for this WTB title. Those really upper floors cannot be no more then 10 square feet if that. Honestly, one big wind storm and this thing will snap in half like a twig.

Yes, the floors will probably be tiny (again, a small condo spanning 2-3 floors would be awesome!) - no, I have faith that this will be a very strong building and we need not worry about it falling over.

That last pic oughta 'splain to the doubters how this thing will get that high and be stable. I have no doubts, personally. That statement about the wings pretty much says it all.

Dubai has a lot more orcs than that working on this project and when completed will be only a tad bit more evil.

[AZheat]

According to some Tolkien experts, this would be one mile tall and would take an army of Orcs some 600 years or so to build.

That's because the Orcs rip each other to pieces whenever there's a disagreement and it slows down the project.

Just a thought about how slender it looks. When The Burj was just a few stories high I thought the base looked extremely small. As it's grown taller the area with the wings now looks quite large. I think some of this is a sort of optical illusion probably the result of photos from various angles. I think it will appear much thicker as the height increases and the wings start to catch up. By the way, Vanhenrik, that first rendition is excellent.

Watched it myself last night. It's amazing how the project has progressed with all of the issues that have come up. Between the glass issues, the fact that no one there knew how to build a concrete block wall properly, and that the 16th floor plate was set with a two inch deviation... you would think they would only be at the 20th floor by now.

Current estimates put the finished height at around 940m.
The building’s foundations have even been dug to an extra deep level to enable the addition of further storeys as construction progresses. The tower will feature a luxury hotel, private residential apartments, commercial space and a viewing platform 124 floors up. The tower will be so high that the air on the building’s upper floors will be thinner than the air on the ground.
Construction is moving fast - one floor per week is currently being constructed and the Burj Dubai is slated to open for business in 2008. The desert conditions mean that building techniques have had to be customised. For example, builders mix ice with any concrete they use to make the concrete set to strength in the hot desert temperatures.
The Burj Dubai is concrete on its lower levels with a shining steel structure on top. It’s been designed without any horizontal surfaces, to prevent desert sand from settling on the building and weighing it down. It also has a twisting, continually changing shape to counter the effects of the strong desert winds.

It will also show Saturday morning at 10 am central and several times after that. I have the DVR set to record it.

Amazing that the project could go over 1000m! Sure am glad I decided to search the world's tallest building recently or I would never have known about this until it was finished. Now I gotta find out about that Kuwait project.

[mightygoose]

as i said three pages ago....


yes but considering the mubarak tower(1001m) in kuwait, and the noida tower (1000m) india are now approved andundergoing final planning and construction begins on nakheels bigger penis entry (the al burj) very soon,

a 900ft rabbit might be exactly what we get...

[John Hinds]

The chances of Burj Dubai being upped to 1000m at this stage are zero. The company that built the foundations said it couldn't hold anything higher than 900m.

[ZZ-II]

1000m Noida tower?? have thought the project is dead!

[SkyWatcher]

Then I guess they won't hold the title very long will they?

I also just read where the Noida tower is called a flawed project because of the soil and the lack of water services and that they might not ever build it.

Can't find a thing on the Mubarek Tower as far as pics go...anyone have a link?

Officials finally admitted that Burj Dubai is at least months off schedule:
Gulfnews: "Dubai: The world's tallest tower, the $900 million Burj Dubai, is months off schedule after its cladding work timetable was thrown into disarray last year, officials admitted."
Bloomberg: "Burj Dubai, the world's tallest skyscraper, is facing construction delays of at least a year after a leading contractor on the project went bankrupt, leaving the tower without any external walls."

[SkyWatcher]

Wow, that's a cool looking tower as well...so this one is approved? What else has to happen before the dirt starts flying?

[M.K.]

I don`t know. I see this bldg quite thin on the middle already, not 64m wide at all, it seems less. Maybe some Viagra for the playmobils should be necessary to make that thing growing up faster :haha: , as it not seems like the renderings at all. Also they are not such confident about the structure, as they even not started putting cladding or windows in exterior. What are they expecting for? the structure is already in middle and nothing is made as finishing, it has only concrete. Maybe they will complete these concrete with steel to make it wider and higher and equally to the renderings. The renderings show more convicted appearance than this construction. :sly:

^^ Read this thread and you'll find the answer to your questions

[kenratboy]

It's getting so...tall!

I bet the view from the top is pretty good right now.

Its amazing, if you went to Dubai 50 years ago and told the city leaders that they would one day have the worlds tallest skyscraper someday, it would be blown off as a joke. Truly amazing.

[Sky Tower]

About 15 years ago, 95% of what is there now wasn't there!

Only that far back it would have been laughed at!

[kenratboy]

Its amazing. Think about cities like London, San Francisco, Tokyo, etc. that have just gradually 'grown-up' - Dubai has simply EXPLODED.

‘History rising’, but when is it arriving?


In downtown Dubai, the iconic Burj Dubai creeps further into the sky day by day. When the tower is complete it will be the tallest building in the world by some distance, capturing that honour from Taiwan’s 509-metre Taipei 101 skyscraper.
The tower is scheduled for completion by December 31, 2008 and to top out at around 808 metres.
But with builder Emaar this week admitting that construction is now running two months late, both the final height and completion date are in jeopardy.
While Emaar admits the project is “two months” behind schedule, it claims there is enough time to get the project back on track and ensure prompt delivery by the last day of next year. Others are not so sure. 7DAYS spoke to a construction engineer who has worked on numerous projects throughout the UAE - including at one point on the Burj Dubai project - who told us: “The original company - Schmidlin - which was part of a joint venture to provide the glass cladding for the project is no longer involved as its design failed water leak tests. A new company, Far East Aluminium (FEA) is now in a joint venture (JV) with Arabian Aluminium (AA) and it says it can provide glass on site from May of this year. However, AA-FEA will have to design and submit a new proposal. This has to then be approved by the consultant on both looks and functionality then tested on the prototype before full-scale production can start. As we can see, the tower (which is already the seventh-tallest building on Earth) is 100 storeys high, but without a single floor having been clad.
“The JV also has to now manufacture the tooling required to make the glass panels,” he said.
With all this in mind, 7DAYS asked the engineer if, in his opinion, the Burj Dubai would be completed on schedule? “No” was the answer.
The final height of the tower is also the subject of much conjecture. Late last year 7DAYS saw a confidential document relating to the project in which Emaar recognised that they would have to scale back their ambitious 808-metre target height for the tower to just over 700 metres. The reasons for this downward reversion came from a combination of time constraints and the aforementioned construction difficulties.
Emaar originally envisaged the Burj Dubai topping out at somewhere in the 700-metre range. As the project progressed, though, so did the scale of the builders’ ambition and a final height figure of 808 metres was posited by the tower’s designers and accepted as the ‘touchstone’. In the document seen by 7DAYS - circulated to subcontractors integral to the completion of the project - Emaar inserted a couple of lines stating: “The main contractor has revised the completion height to the original figure” - just over 700 metres. Unsurprisingly, there was little fanfare surrounding this downward revision, and just before the turn of the year, another document was circulated which reset the 808-metre figure as the target height.
Why did Emaar scale back the Burj Dubai from the 808-metre target, and then reinstate it? 7DAYS spoke to another engineer working on the project who said: “The project was scaled back to its original 700-metre target due to time, or the lack if it. Emaar simply can’t afford for the project to run past its scheduled completion date of December 2008 for a number of reasons.

TALLEST BY SOME DISTANCE
“It is established that even at 700 metres high, the Burj Dubai will be 40 per cent taller than the Taipei 101 and thus the world’s tallest building by some distance. The taller the tower gets, however, the higher the construction cranes which supply material to the summit need to be, and even in such a benevolent climate, wind speeds at heights of 700-plus metres can get quite severe and cause ‘winding off’ of crane work. As such, the cranes would only be able to safely operate for about 100 days a year between the altitudes of 700 and 800 metres. That’s not to say 800-plus metres could not be done at the Burj Dubai, it most certainly could be, but not if Emaar wants to complete by end 2008. The money for construction is not an issue, there just isn’t enough time for Emaar to go higher than about 700 metres,” he said.
The point is, Emaar has changed its target height for the tower on at least three occasions. If time is tight, it is entirely conceivable that it will do so again and so it remains that no-one is entirely sure just how tall the structure will be, and Emaar is being very cagey about going public with a definitive figure.
That Emaar wants to deliver on time is admirable, given that many projects in Dubai seem to finish ‘whenever they are finished’, but there are two good reasons behind Emaar’s desire for punctuality. Firstly, a number of commercial contracts have been signed between Emaar and prospective tenants of the completed tower, not least of which is the flagship ‘Armani Hotel’. If the tower is not completed on time, financial penalties could be levied against the developer depending on how late it is. Emaar would then find itself in a similar situation to that being experienced by Airbus, which is seeing its profits being severely eroded through penalty clauses for lateness being triggered by the two-year delay to its A380 super-jumbo.
Secondly, in true Dubai style, the issue of image is paramount in Emaar’s desire to get the tower completed on time. Our Burj Dubai engineer commented: “There is a great deal of prestige attached to having constructed the tallest building in the world. In the same way as the Burj al-Arab pitched itself as being the world’s only ‘seven star hotel’ (there is actually no such thing, five stars is the highest recognised hotel accolade), the Burj Dubai will doubtless trumpet its ‘world’s tallest’ credentials at every opportunity.”
But Emaar knows that the Burj Dubai’s time at the ‘top of the tree’ might well be brief. Within Dubai, rival developer Nakheel is set to construct the ‘Al Burj’ tower at Dubai Waterfront. The height of the Al Burj is also a secret but some reports suggest a projected height of 1,000 metres - which is not at all fanciful - meaning that the chances of Nakheel not trumping Emaar’s Burj Dubai seem remote.
“There are two proposed developments for towers in and around Kuwait City, and another in Australia, all with projected heights of 1,000 metres plus, but these are at least ten years away in terms of completion. The Al Burj is likely to begin construction imminently and this is the present danger for the Burj Dubai in terms of remaining the world’s tallest building,” our engineer said.
“The advertising tag for the Burj Dubai is ‘history rising’. Emaar wants to get the project completed to maximise the time it occupies the slot of being the world’s tallest. The building is some way off being complete and already its place in history is under threat. When the Al Burj and other buildings are completed, Emaar will learn, just as the builders of Taipei 101 will, that records are made to be broken,” he concluded.
That the Burj Dubai will be the world’s tallest building when complete is not in doubt. In the minds of two engineers working on the project, however, it will not be finished by the target date of December 31, 2008, nor is there any real indication of exactly how tall it will be. Seven hundred metres? Eight hundred metres? Who knows? Money is not an issue in the final height of the project but time, or the lack of it, most certainly will be.
Emaar did not respond to 7DAYS’ requests for comment this week.

[M.K.]

:previous: Well, I read the book above and my oppinion is everything too different and big challenge to conquire represent some delay and big expectations. All new things with complete new engineering and not common all over the world like A380, The tallest one, new inventions require some time enough to make sure in our atmosphere. Money is not the problem, but time is. Everything is possible, but depends on time and the way in doing it.
Let`s see. I would love riding either in A380 either climbing this tower when both are ready. Who knows. Nobody knows the future... :shrug:

it geting taller end taller ! yes yes yes ! so fun ! :cheers: :cheers: :cheers: :cheers: :cheers: :cheers: :cheers: :cheers: :cheers:






i wonder how athentik this skediual render is http://www.burjdubaiskyscraper.com/progressbar.gif


now on http://www.burjdubaiskyscraper.com/ they haw change the top hight from 808 meters to 950 meters http://www.burjdubaiskyscraper.com/right2.jpg


i hope 1001 meeters

[Fabb]

I'm glad that it passed the 400m threshold.

[malec]

Has nobody read the article I posted? They claim they've reduced the height back to 700m

Why did Emaar scale back the Burj Dubai from the 808-metre target, and then reinstate it?

So, the truth is : we don't know for sure...

[ZZ-II]

the tower will be at least 800m!

[nezzybaby]

all the article does proove is that the 1011m version is sheer bollox like we all realised, the 808m version looks better finished to me, but 705m is fine, and the useable floor space was always gonna be the same.

[M.K.]

:notacrook: I think 807,7m is quite a big Mark to be reached and a great challenge. So, I don`t immagine going neither more upto 1000m neither less 750m. 807,7m is fine.:tup:

[SkyWatcher]

Yeah, the article really shed no light on CURRENT target height other than to say the original 808m had been reinstated at last check.

I doubt anyone will know the actual height until the tree goes up top.

now that is a more accurate pic .,the bottom pic , also looks like it is finally getting fatter, due to the wings catching up

[vanhenrik]

Burj Dubai is not only behind schedule, but might face a rescale back to the original 705 m height. This is due to time difficulties and the failed water leak tests of Schmidlin claddings.
7days: "Late last year 7DAYS saw a confidential document relating to the project in which Emaar recognised that they would have to scale back their ambitious 808-metre target height for the tower to just over 700 metres.

[Dac150]

That's a shame, hopefully they can make the 808m work somehow.

[SkyWatcher]

The quote he posted isn't the last word on it. The range listed on their website is 705m-950m.

I am watching the show on Megabuilders right now [on tape]. Very cool show. They are talking about the extra weight on the foundation to add height right now.

[ZZ-II]

i'm sure it'll become 800m. would be very happy with 800....and when it's going to be taller it's also great.

[malec]

That's not exactly what the article says :


I didn't mean it that way. I was just surprised nobody had replied. In fact I heard about this article a few months back. Someone tried to edit the burj article on wikipedia to 705m and they argued saying an article will be released in the 7days newspaper

IMO that's pure bullcrap. You've all heard stories that the Burj Dubai will be 800 meters (In fact, it was nearly confirmed!), then 950 meters, then more recently 1011 meters, and now 700? :koko:
I think that would be very improbable. :yes:

[Pandemonious]

It took an entire team of architects working at SOM to do all the drawings for this building. I worked there last year, and less then about 5 months ago, after the huge team was dismantled to work on other projects, the final sections/elevations/construction documents that I saw all said 808 m to the pinnacle. That will be the height of this building. Even if it was changed to go to 1,000 m (which is pretty much a chance in hell at this point IMO just given the logistics of it, and the problems they are already having with the tower (curtainwall fails wind tests and can't even be installed)), it would likely be just a much taller spire which would completely unbalance the design in my opinion. The way this building's setbacks taper up to the top was carefully thought about, and many of the lower setbacks have already been constructed. Do you ACTUALLY think they would change the height now? I am not saying it is impossible, just that it would really affect the overall design of the tower in a negative way IMO, and seems HIGHLY unlikely to ever happen.

If they do scale it down, that would also be a shame, as the setbacks have been designed to taper to a much taller pinnacle...

[innov8]

I was watching that program also, they have had so many
set back with this tower. The curtainwall failing the wind
tests, like Pandemonious said, is something I would have
thought they would have figured out way before
construction started.

I was shocked to learn from the program that the builder
has had one hell of a time having glass made that lies flat
and does not distort reflections when looking into it. :rolleyes:

[SkyWatcher]

It was also a shocker that it took over 5 months to teach the crews how to lay blocks correctly. Makes you wonder how they are going to make the deadline.

you're absolutely right

[Beyond 1000]

you're absolutely right


I agree ZZ and pandemonious.

I do not believe the 705m number at all unless Emaar announces it and even then they may be ploying.

I have BD at least 800m but possibly with a taller spire it will reach between 830m and 860m. That is my feeling and I'm sticking to it.

So to those of you who still are feeling that BD will be 705m, :yuck: to you.


Unless we get absolute solid information of a lower than 800m height, then we are turning this thread into a :banaride:
