So no further increase since your previous pic earlier in the day. Still at 770 meters then.

Yes, it sounds or looks better to say over 200 floors, but there are not really. lol

Seriously, once they got above the point where the floors were inhabitable who cares how many there are? It's all ego and window dressing above the point where it serves some purpose other than broadcasting TV signals. Some are way too focused on numbers IMO.

I have a question about floor counting. I know Empire State Building has 102 floors, but a dozen or so are above the observation deck and into the thick base of the spire, which spire it self was a later addition. Are those floors inhabitable, and if not, why are they included in the count? Does this apply here?

Also in Burj Dubai, what is considered to be roof height?

This tower has now surpassed the 2500 ft mark.

New Dubai imagery in Google Earth

Dubai has been updated in Google Earth, showing Burj progress to maybe a few months ago.

The fins (or 'strakes' as they are called in the engineering world) need to spiral to create the required dampening effect.

Yes they look a bit ordinary, but as has been said, they won't really be visible from the ground.

Like the spiral formations around bridges' cables that serve the same purpose, this time against parallel water flow on them, which might cause resonation with the wind (see Rio-Antirio bridge)

Incredible, absolutely incredible. I think this could be one of the new 7 Wonders of the World. Truly one of mankind's greatest achievements, getting this high and striving for something even taller.

Sorry if I missed anything but how tall is the tower now to the tip of the spire?

Is there any info on how fast the spire gets pushed up? like how many cms per hour.

Awesome picture update OTR. The little boxes on top of the spire are probably the beacons, right?

Correct, and as the tallest point now maybe they should be switched on.

After watching this building grow for the last three years, I can't believe I'm actually seeing the spire go up. Truly remarkable.

Waking up to this news... priceless!

Can I request a 'long shot' of the tower?
