Yes, some of towers are powered up. UDC's Tower 4 and Tower 1 are powered, and there are people living there now. The La Riviera tower, First Qatar, is also powered up (i own an apartment there, and last time I was in the building was early December 09). Not sure when they will have water though ,, Anybody has been there lately??

I am not sure when exactly the handover date is for my apartment, but i think it is pretty soon.

Would you mind sharing with us which building/tower you are talking about?
