Scheduled to be the world's tallest building upon completion in 2008, the Burj Dubai tower was at 79 floors on October 29, 2006. The one-billion-dollar (U.S.) skyscraper is expected to surpass the current tallest tower in the world, the Taipei 101 building in Taiwan, by hundreds of feet when finished. The final height has not been disclosed.
The thousands working on the project add a new floor to the Burj Dubai every three days. The tower will contain shops, offices, apartments, entertainment facilities, and a hotel.
