The construction began on September 21, 2004 and was officially opened on January 4, 2010. The tower's architecture and engineering were performed by Skidmore, Owings and Merrill of Chicago, with Adrian Smith as chief architect, and Bill Baker as chief structural engineer. The primary contractor was Samsung C&T of South Korea. The building has 160 floors and features with a restaurant and the Armani hotel.  The Burj Khalifa should be one of the 7 wonders of the world because the Khalifa Burj height is considerably greater than any other building. The Taipei 101 has 508 m as height while the Burj Khalifa is over 50% higher than that. In addition, the Burj Khalifa is not only the higher building in the world. It is also higher than the CN tower; the higher structure sustained wireless that has 553 m. Is even higher than the Warsaw Radio tower, destroyed in 1991, that held the record for the tallest structure built with 646 m. Therefore it is notable that the tallest structure built by the man is not an antenna or tower, is a building with more than 800 meters, that kind of construction had not been seen since the empire state building.
