www.burjdubai.com looks pretty but thats about all the use it has. It is well known the information on it acts more like a PR and Marketing campaign than a source of facts. Sometimes the info is accurate but the SSC community tends to know better.

It might be that the eventual aim is to have a floor built every 7 days, but at this stage we cannot form our own conclusion from direct observation as they have barely started the second steel floor and so the best answer to the original question is 'We dont know'.

Awesome photos Imre, I can't wait until the building is finished.
Off topic here but I was wondering the other day what kind of insects are out there in Dubai, like huge ones, deadly ones, etc.

What a random question ... the deadliest ones might be red-back spiders (Australian unwanted refugees).

Youi'll not find them on Burj Dubai though.

I hope someone can help me. I am trying to understand the size of the Burj Dubai. What is the diameter of the circle below? Thank you.

Roughly 100m LoverofDubai. Thats considering each tier streches 50m from the centre of the core.

Thanks Shamilo for the info and I understand Dettol's reaction to that figure: "wtf??" lol it was the same reaction i had. where did you get that figure from and how accurate is it?? i mean, that 'floor per day' rate is even longer than that of the construction of a concrete floor.

However, i thought id put that figure to the test and i did some simple number crunching and came up with this:

Current Date: 11/1/08 - 2nd week of the year
total number of weeks in a year = 52

current floor of Burj Dubai = 156
total no. of levels = 205, hence, no. of levels to go = 49
taking into account that each floor takes approx 7 days (and i know this may be sped up to 5 or even 4 days), then:

49 more weeks til Burj Dubai T/O? - appox 2nd last week of december 08 - the scheduled completion/top off date?

so even though 7 days per floor may seem like a way-off figure, it technically fits into the buildings construction schedule. I'm no architect or engineer, but i hope i am right here and if not, maybe Fury or Cullawulla can shed some light on this.
Thanks

The plain and simple fact is that the rate each floor is built has varied for the entire construction of the building, and will continue to vary until it tops out. There was a time when the concrete core was rising a level every 3 days, but there were also times when it didn't rise for several weeks. The only times you can really say the tower is rising at a specific pace is when the construction crew hits a stride in between mechanical floors and knows exactly what they are doing, but that pace will only last as long as they are building the same floor over and over. As soon as it changes, things slow down. This steel structure is a completely different animal from the concrete structure below it, and it's going to take some time before the people who are building it get used to what they are doing. It's going to go a little slow right now, but soon it will hit a steady pace and frankly, we don't know what that pace is going to be. So all we can do is wait and see.

Actually, that red circled area is the foundation mat for just the central core column and is around 74m in diameter. To give you an idea, the building reveals this first setback at this diameter at L19 up to L43 for the first 3 sebacks.

The 3 tiered podium section extends well beyond this foundation mat by a shallower foundation extended beyond what you see in the photograph and extends to 91m in diameter.

Again, the 3 buildings situated on the outskirts of the podium section extend to a base diameter of over 127m with the underground carpark sections extending much further out again filling the whole dugout area that takes up that photograph.

I am sorry, but I did not understand anything you said. It is too technical for me.

I will rephrase my question. If I were to draw a red circle around the current footprint of the Burj Dubai, what would be the diameter of that circle (this circle only goes around the tower, not around the buildings and the underground areas)?

I ask for the diameter because I am trying to find the area of that circle. But I would also be interested to know what the area of the base of the tower is; if anyone knows that.

Thank you.

Seems like cities near coast don't care, but in a near future, great cities will have to deal with it.
Historically during warmer climate periods the sea level doesnt really rise that much. But im sure they would be able to handle it. Just like many other older cities have already had to do through history.

Hey LoverOfDubai,

Im sorry I didnt paste this link up when I initially responded. Its not official but a lot of time has been spent explaining the "Tier Methodology" as it puts it. You will find the first tier, that which encompasses the raft foundation in your picture, is stated as being 51m from the central core.

You will also find figures for the podiums below the first tier, which Sky Tower touches upon in some way in his response above. I hope this information answers your question but feel free to PM me if you need anything further.

Cheers for your input Sky Tower.

Thank you to Bikes site www.burjdubaiskyscraper.com from where I am sourcing it.

i think as Burj Dubai rises the steel sections will be constructed quicker. they end up real tiny compared to current sections so maybe the upper levels will be hoisted up as one section and simply bolted on. the pinnacle will be also hoisted up and telescoped into position as the steel structure is built around it. i think it will top out within next 6 months.

I don't know if they're going to do it with prefabricated sections wich are hoisted up in one time. Measurement of steel constructions is very precise compared to concrete constructions. Maybe they do hoist up big sections, but the fitting and fine-tuning of the construction will take the most time. Especially at that height they're must be very careful with constructing. And besides they're going to uplift a great pinnacle wich has never been done before at such scale and such height! The more I think about it the more interesting it becomes! We'll see it the next half year!

Thank you.

The diameter of a circle around the current footprint of the Burj Dubai (at ground level which is the base of podium 1) is approx. 184.6m, according to my model. That figure may be slightly off by a tiny bit but it's very close. The area of podium 1 (base of tower) is approx. 6713m squared. Hope this helps

6 months? sounds very optimistic ....but i think they'll do it.
