I remember seeing a documentary on them building the place and it was insane how they did it. Burj Kalifa or something is the name of the building. They had a concrete pump pipe built into the center of the structure that they could hook up to on any given floor to pour the floors.
The concrete was a specially designed mix that is something like 10000 psi and can resist cracking. The top of the building moves something like 25 or 30 feet either way on any given day.
I was wrong, just looked it up and it was only 5 feet of sway at the top. still could make you sick as hell.
ETA: also. 60000 tons of rebar in it, 431000 yards of concrete and 22 million man hours.

If you're interested in these types of things, watch how Burj-Al-Arab was built. It's amazing the intricacies and cutting edge technology that was involved in building it.
