Great read, thanks for the link!

Here's a bit more of the article:
Quote:
The initial scheme was for a building of about 1,800 feet, 317 feet taller than the Petronas Towers. Yet the clients made a request: Overengineer the foundation, just in case we change our minds. Which the clients did. Repeatedly. On trip after trip to Dubai — even after a hole was dug and giant caissons were set 150 feet into the sand, even after the building began to rise, a floor every three days, into the desert haze — the SOM team kept getting the same request: Can you make it taller? They worked the problem in the wind tunnel, adding fins around the perimeter (like dimples on a golf ball) to create surface turbulence and reduce the lateral forces on the building. They worked the problem with concrete specialists, engineering a high-strength mix that could be pumped into the sky, like a giant drip-castle. But one thing needed no tweaking: the buttressed core. It seemed to permit limitless growth.

Does anyone know how many of the small windows there will be for the cladding of the mechanical floors? On the render I have seen it looks as if there are 6 but not sure

"I also heard somewhere they will have self locking doors to the terraces for when the wind is too strong."

Let's hope that noones on the terraces when they lock!

Enjoy.

Hi Harry.

CS is another structure I am watching closely. Not much in the way of info or plans has been released as far as I know. Starting to get lots of pics of the construction thanks to you ( and others ) but I need info to make an analysis. This one is version 3 of the Burj - as new or changed info comes out I revise it and make it as accurate as possible.

That's good. I was looking at the videos that Imre posted, looks like there's a terrace on the top of every tier, there's holes on the cladding at the end of the wings on podium 3, I take it they are for supports to hold up a glass railing of some kind so that nobody falls off lol. I've finished all the floors with cladding on the model I'm making, I'm only unsure about the railings on the terraces and what the mechanical cladding is like (hoping this with be on the real building soon). I'm hoping to finish some renders by the end of the year and they will certainly be the most accurate in terms of size and looks (thanks to you!), will post AutoCAD pics soon followed by the 3D Max ones hopefully....

It Kind of takes you by surprise that almost all Dubai leaders are so effective in expressing themselves in the english language. I remember watching some Saudi royalties that were impressive as well but they were educated in the West. I wonder what was the case with him.

Hi all.

Hey helghast - I don't have any actual tier 22 prints - but ...
Here is the start of tier 23. It shows the terrace or roof of tier 22. So this print is the shape of tier 22 not counting the start which has tier 21 terrace. If you get what I mean - tier 22 has 2 wings. Those wings are approx 6 meters deep and wide and the center circle ( the lower/internal/unseen from the exterior part of the pinnacle ) is 2.1 meters in diameter.
