I'm not Fury but I think I can answer this one too

All mechanical floors have been left uncladded longer than 'normal' floors; this is because at that floors large equipment will be placed. Some equipment can be placed in an early stage, far before any cladding has been done, but I can imagine some equipment which must be protected against any dust, heat or water, can only be placed in a late stadium. Therefore they will leave an opening through which they are able to transport all the big equipment that still needs to be placed on that specific mechanical floors.

You are very right with that. Only problem is we don't have a technology that would confront a cleaning and maintaining ability for a building this high (or building that is 600+m). Plus, there is always a possibility that the chopper any flying device may get caught in the wind and crashed on the building.

How about a device that act like a car wash but moves vertically (and can reach continually for at least 100 meters?). That may help.

That really wouldn't be a sight.

Here is a shot from 08 07 12. We can see the roof and penthouse of the office annex (on the right side) look finished and cleaned.



Here is a shot from 08 11 26. We can see the penthouse has been partially taken down and there is a bunch of stuff lying around up there in preparation for the new steel levels. Also there is 2 tower cranes erected beside the annex.



Here is a shot from 08 12 19. We can see the penthouse appears to be totally revamped and the start of the (first ?) 3 steel levels being erected.

Hi Fury, I remember posting about 15 months ago that there was a suggestion of a 3 floor revision to that part of the building....after
reading some of the project management notices before I made them publically available.
I don't remember uploading them to the website though, but I do remember posting it here....with many forumers saying
I was full of it.
I'll try and find the original post later on....just for posterity!

I don't know why there's all this discussion about washing windows. They'll wash windows the same way as on other skyscrapers. There will be days that it's too windy, yes, but that's not unique to this building, although they may have more wind days near the top than other buildings.

Height isn't an issue, since any fall from more than 15m is life-threatening. I know it's mundane, but they don't need to reinvent the wheel to wash the windows on this building.

True, but if there would be a invention of a new generation window washing system, it would be invented for Burj Dubai, as this building is the one needing it most. (like the fastest elevator in the world, revolutionary emergency evacuation plans, etc..) But again, washing the windows faster is not as important, so it is completely normal if they are using standard BMUs.

if they can find a cable to reach the ground level from the highest crane, it shouldn't really be a problem for BMUs either...
