The floor above this is L126 as the skydeck will be classed as 124-125 and on this side of the picture the construction pinnacle goes up to L129 and they're another level higher on the far side for tomorrows L130 pour!
I see it Skytower, you guys are correct.

How high do you estimate floor level 130 of TRUE GROUND....that is official height of how this building will be measured?

Looking at Fury's picture, they've completed the pour for the first two "small" wings now. You can see now how when they have those small wings on both sides, the pointy bits between the wings will become the new wings, off which they will start taking setbacks (of course we've seen that in renders but it is cool to see it in reality).

Why didn't you nuke my post about you in the UAE section? That's what I would have done if I had been you probably. No one would have ever believed anything I said again.

It's an open forum and people are entitled to freedom of speech, whether I like it or not, it's up to everyone to decide what they believe.
I maybe a forum God, but that doesn't give me the right to act like one!

Pillar diameter is something I've wondered about as well ~ you would think that the pillars at the lower floors would be huge then tapering in size towards the top. Can anybody from Arup explain this one

One thing I do remember seeing is the documentary on the building of the Petronas Twin Towers and how they had to develop a new mix of concrete ~ they ended up with a high silicon mix which was strong enough for the pressures involved.

Interesting stuff !

Well I'm sure at different stages of construction they're using different amounts of rebar and different concrete matrix's, but remember that the base of the tower is wider and at the mech levels there are huge weight transfer beams which distribute loads to different parts of the structure.
The first setback has only 19 stories to support and the 3rd setback has 23, but those levels are slightly shallower at each setback, so the transfer loads remain pretty much the same!
From the foundations up, I would image that when finished, the bearing loads would be evenly distributed accross all support collumns and core sections.
This will have a bearing on how setback/core ratio will be built and electronically confirmed by the numerous strain guages and extensiometers built into the building where they are constantly monitored in the tech section in the basement of the building.

That's why construction slows way down at the mechanical floors. Someone was trying to calculate the average time per floor since the beginning of the year a few pages ago and forgot to take that into account. It's tricky to redistribute the load. On the Trump tower, each setback has taken around 3 weeks or longer to build, so we're lucky that we only have a week or week and a half of delay on this thing

The Race for the Tallest Skyscraper


Source: Business Week
Publication date: May 1, 2007


The race among the world's cities to build the ultimate record-busting, flat-out tallest skyscraper on the planet is fast and furious. And the obsession to build mega-structures in nosebleed territory is particularly acute in much of economically dynamic Asia and the oil-rich Middle East.
The frenzy of high-powered construction projects promises to transform 21st century skyscraper architecture in a big way. Currently, eight of the world's tallest 10 skyscrapers are in the region. And the present reigning champ among skyscrapers globally is Taiwan's Taipei 101, a structure that climbs up 509 meters or 1,671 feet.

Of course, a super-sized building boom is now raging in parts of the Middle East such as Dubai, Abu Dhabi, Kuwait, and Saudi Arabia. In fact, Samsung snagged the construction work for the monstrously high Burj Dubai, a tower complex slated to reach 800 meters [2,624 ft.] in height--which will easily blow by Taipei 101 when it's completed in late 2008. [It was designed by the U.S. architectural firm of Skidmore, Owings & Merrill. The architect was Adrian Smith.]

"Something More Reflective" Even lesser-known regional cities with a burning ambition to make their mark, view big, gutsy, and distinctively designed skyscrapers as potential game-changers--and are willing to offer serious incentives to get them. That's pretty much what city leaders in the South Korean port city of Busan [formerly known as Pusan] hope to accomplish with the planned 560-m. [1,837-ft.] Millennium Tower World Business Center, expected to be completed in 2010 or 2011.

This will be no bland monolith. New York-based Asymptote Architecture, which won an international design competition for the project that will spawn the tallest building in Asia, came up with a concept that features three tapered towers emerging from a powerful base foundation of floors. It offers stunning ocean and mountain views. "They were looking for something bold," says Hani Rashid, a principal architect with Asymptote. "We actually went in and tried to do something more reflective, to reset the game in terms of this tower mania " in Asia.

Whether the Millennium Tower in Busan [a city also hoping to host the 2020 Summer Olympic Games] results in a huge economic lift is uncertain. But plenty of cities in Asia are definitely willing to roll the dice, and that's sweet news for international architectural firms and general contractors alike. "The market outlook for ultra-high buildings in the region is pretty bright," says Kang Sun Jong, vice-president in charge of architectural design and consulting at Samsung.

Economy Drivers These super-structures are about more than just civic pride. Well-executed skyscrapers can be a real economic-development driver. Consider the 452-m. [1,483-ft.] Petronas Twin Towers in Kuala Lumpur, built in 1998, which was the world's tallest until it was eclipsed by Taipei 101 just six years later.

The Petronas Towers " may no longer be the tallest building in the world, but it changed Malaysia and the perception of Kuala Lumpur" worldwide, says Goh Tuan Sui, chief executive officer of property consultancy WTW Malaysia. "A world-class building can also raise the bar for other buildings in the city, be it malls, office blocks, or hotels," he adds.

When it comes to sheer scale of tall building construction activity, it's hard to match Shanghai. Since 1990, the city has erected enough high-rises to fill a big chunk of Manhattan [see BusinessWeek.com, 2/8/07, "Shanghai Rising"].

The 88-story Jin Mao Tower, with its distinctive tiered pagoda design, is the tallest building in China, rising to 421 meters, or 1,380 feet, or at least it will be until the 492-m. [1,614-ft.] Shanghai World Financial Center is completed in 2008.

Girding for Materials Shortages So is the current wave of next-generation skyscrapers starting to bump against the limits of modern-day construction engineering and material science? Rashid, with Asymptote Architecture, doesn't think so, given new construction materials coming onstream, advances in computer-aided building design, and the increasing use of robotic technology in building. "There are new materials emerging that could replace steel," he says.

Probably the biggest challenge for general contractors at the moment is getting their hands on needed engineering and construction talent, and even some basic construction materials, in a timely fashion, given the construction boom in Asia and the Middle East. "So many projects are being undertaken at the same time that securing in-time delivery of construction materials has emerged as a challenging task," says Samsung's Kang in reference to the Burj Dubai project.

As long as city planners in Asia and the Middle East have the financial wherewithal and vision to keep pushing the limits of construction engineering, the global "edifice complex" seems sure to continue.

Looking at the pic below, you were right. I'm almost 100% convinced now that they won't go above around 160 floors. The floor plans are already getting small.

This is how they will transfer the loads of that section to the re-enforced transfer beams on the last level of mechanical floors below it. I believe those jagged sections which we're seeing at the moment are not poured, but pre-stressed, pre-assembled sections that tie into the core wall through steel tie bars and are completely self supporting. The outer edges to be extended later will need supporting by the column below it, and will be marginally thinner to save weight. There are many other instances of floorplate weight saving throughout this building's construction on all levels.
Looks like you were wrong.

well on the official website, still has lev124= 442m,.
the emaar sign at the site says lev126 or 2x5m floors= 452m.
so 4 more levels x 4m each lev130=468m?

You should pick up a copy if you can, has some other interesting large projects there.
I donno wich of the height is true but one of them should be !!! personnaly I don't want the 893m version I prefer the 934.5m Popular Mechanics you say haaa
I sow that everybody just flipped by this pretios information that changes the information know until now !!! June edition of Popular Mechanics reveals something more I gues they have some snaggled information behind

Since when has Popular Mechanics been a reputable or reliable source of information!? They have always stood as a commercial publication with a higher add content than prime time free to air television!!

me too! but i found out that they cant start the cladding on the lower floor bcoz the podium contractor ****sup and cant finish the transition details in time...after 2 and half years hehehe. what a pity....

it was said before somewhere in this forum that inorder to catch up the 12mos delayed, the cladding will start at 4 or 5 different levels. and that levels is probably floors above machine roooms. my 2 cents...

THANKS imre for the close up pics of the initial claddings. it was indeed a surprise and show off to shut up detractors.

imre, i think i saw you when youre taking those beautiful pics.

cheers everyone, expect the rush on the 3rd week...


w8 a minute, i believe skytowers 1011m is possible, ive seen it in my dreams... what he forgot to depict is there are 30tiers in the latest model.

Honestly anything below 800m would be an anticlimax with all the speculation going on.
