1. Because the mech floors will house heavy equipment and the best practical way of getting it here will be to hoist it in from the outside.


2. Because the mech floors require a different cladding that allows ventilation

It's from AFP, which is a French news agency. But nice try.

Because there's not nearly enough space there for an observation deck.

TIME, that’s the main reason. they have to leave it uncladded so that they can catch up with the delay. By doing this they can go ahead installing cladding above. the mechanical flr cladding system was changed a little bit from the old design. you call it infill panels. So practically they can start installation of typical panels in 4 different levels above MF.

What are infill panels? It’s the cladding you install to fill in between the cladding below and above. Great example is the vision cladding for ICC. They have all the spandrel cladding installed first then followed by closing it up with the infill vision cladding. So practically, for ICC they can install at every other floor if they want.

While it’s true that heavy equipment needs to be lifted from the outside, one can always do that in what you call leave out panels. No need to leave the whole mechanical floor uncladded if that’s the only reason. Intiendes? Just look at mori for example.

NOT QUITE! generally, that is correct. however, for BD it got a an interior louvers and outside its cladded with glass! and SS band alternately. the same glass and ss spandrell you see now. Along these SS spandrel are SS tubes around the building. the ventilation is allowed thru a concealed slit on the horizontal cladding frames. Take note, not all units has these ventilators.

CORRECT! somehow this is correct, maybe they have not started production of mechanical floor cladding yet. they have yet to pass the test for air ventilation (slits on aluminum frames seems inadequate) and acoustic test is other concern. if not properly designed, the slits on the frames would act like a whistler. The other factor are the SS tubes around the mechanical floor cladding. The band that you see in the renders are the tubes. At level 18 for example, the upper and lower tubes serve as the rail for the cleaning equipment while the rest are just architectural features.

As far I know, logically they did not clad the mechanical floors to be able to shift the pumps, heat exchangers, Air handling units, Control Panel and Transfromers from outside the building using the cranes.

These equipment are heavy, big, difficult to be transfered from place to another.

The internal louvers are must but can be installed easily within few days which will never stop them from cladding the mechanical floors at all.

When you look at the building, you can not find any electo-mechanical work at all such as pipes, ducts, pumps, control panel, transformers which mean that they did not start installation and running of the electro-mechanical system yet.

This means that still many equipment are not installed yet and will be shifted from outside for sure inshallah (God willing).

As Burj Dubai breaks record Samsung looks for next job
by Monika Grzesik on Saturday, 15 September 2007
The Burj Dubai is now the tallest tower in the world. According to Kim, there are many other plans to build super-tall towers in the region.


Samsung Engineering & Construction is looking to build a new tower in the region whose height will top the Burj Dubai.

The South Korean construction giant is currently working in collaboration with Belgium's Besix and local firm Arabtec on the Burj Dubai, for which it signed a US $875 million (AED3.2 billion) construction contract with Emaar Properties in December 2004.

It is now in talks with a number of developers across the Middle East over plans to build a skyscraper that will set a new record in tall building.

"We have been approached by a number of clients," said Beejay Kim, senior manager, Samsung Engineering & Construction. "Many have tall building plans, not only Nakheel. Kuwait has a project for a kilometer-tall building, Saudi also has some tall tower plans, so do Bahrain and Qatar - everybody has tall building plans, the difference is whose can materialise quicker."

Samsung is no stranger to the construction of tall towers, having been involved in the construction of three of the world's tallest skyscrapers - Tapei 101, Malaysia's Petronas Towers and now the Burj Dubai, which recently became the world's tallest building when it surpassed the height of Tapei 101 at 508m. The final height of the Burj Dubai is being kept a secret but upon completion in 2008 it will be well over 700m tall.

While the past few years have seen the majority of Samsung's energies ploughed into the Burj project, Kim added that having reached this point in the building's construction, it is now time for the contractor to find it's next big venture.

"Until we reached that critical point, it was our company philosophy to concentrate on the Burj Dubai but now that the Burj has reached the tallest point of any other building in the world, I think it's time to look for another job.

"We have worked on the three top tallest buildings in the world right now, so if somebody is looking to build another building in the world taller than this we would love to go for it."

OBSERVATION HEIGHTS
yes SWFC will have its lev100 skybridge as worlds highest public viewing deck at 472m.
Burj Alam which has recently started not far from burj Dubai will have a view deck on roof at 447m.(same as CN Towers)
Burj Dubais will be 442m BUT will also have outdoor observation which i dont think any of these will have?
