Cranes hang from the top of the tower while massive platforms bring needed building materials.

The tower will be home for corporate offices and residential suites. It will also include four pools, restaurants, shops, a library, an observation deck and a 15,000 foot fitness center. The first Armani Hotel will occupy the lower 37 floors.
