OOHH, i thought that was the whole base of the building. Thats just the core that hold the building from the inside. OMG, thats going to be huge!!
When i first saw this thread i thought, not another rumor of a supertall building again, but this one is actually happening. I'm really shock and happy that they are building this supertall stucture. I wonder when the show MegaStructures will do documentary on it??
