I wrote it wrong, I was meant to say that 15th floor will begin in no time.

Hi all.

Nice shots as always Imre.

As I said yesterday the column that looks taller at some angles is the middle column of the smaller wing that continues up. Plans being followed - we are at the top of tier 20 - section 2 at 675.3.

looking awesome .thanks for updates imre.
looks sooooo tall now.
dachacon-ive had polls about creating a new section because there are so many supertalls now. i still hate coming into this section after 2 days and finding 2 pages i have to sif through.
i mooted a for a 500m height for a new section. because there are now a few bldgs in this catorgory.

ive created my own thread here> http://www.skyscrapercity.com/showthread.php?t=600142

i think 600m or 2000ft is too much of a jump. thats double. there is only 3 that would be in this cat anyway.

I read in todays 'Melbourne Herald-Sun' Newspaper that Burj Dubai has no lift that goes all the way to the top....I don't mean literal top but to highest lift core floor ? Is this a first ? I know it is common for very tall skyscrapers to have lifts servicing segments of a building with express elevators to sky lobbies yet most I am aware of have at least one going through to the highest floor. Imagine a cable that long would make this difficult in a building this high.

looking at latest pics, it seems that the steel structure has reached the top of the cranes.

What will happen from here? Will the two cranes be further jacked up another few stories, or have they reached their maximum height and will make way to hoist up the smaller crane?

a question for cull: how tall are the mast towers of the cranes at their current height? 110m??

- The sections of the Favco masts are 4.000 m. high. Each section is made up of 2 - 2.000 m. parts. So if you count the sections you can get the exact height.

Here is something I cooked up a while ago. It shows how they are supporting the masts at the top of each tier and how they are putting in a red section near the top of each tier. They can't add a red section at exactly each tier as 5 sections is 20.0 m. and each tier is 19.2 m.

Hope this helps.

Red - I think from all the plans we've seen that the highest singular elevator run is from the lobby or basement levels up to 123F / 124F for the observatory. Fury's and Cul's diagrams I thought equate this to right around 447 meters. I thought there might be an elevator or two that runs 500 meters but even if that is true, there still is no singular elevator you can take from the lobby to 155F. You'll have to switch zones at least once, if not more, to reach your floor.

the longest lift run is indicated in my diagram. its to lev140 or 514m. from above this is 15 levels of boutique offices and few plant services.
so not many people will need to use a second lift.
of course there will be dedicated lifts to lev124 ob deck.
the tower crane starts from about 565m and current height is about 675m, so yeah about 110m long. soon to be longer
