Burj Dubai

Burj Dubai (Arabic: برج دبي‎ “Dubai Tower”), a supertall skyscraper topped-out in Dubai, United Arab Emirates, is the tallest man-made structure ever built, at 818 m. Construction began on 21 September 2004, and the tower is expected to be ready for occupancy by early 2010.

The building is part of the 2 km2 flagship development called “Downtown Burj Dubai” at the “First Interchange” along Sheikh Zayed Road, near Dubai’s main business district. The tower’s architect is Adrian Smith, who worked with Skidmore, Owings and Merrill (SOM) until 2006. The Chicago-based architecture and engineering firm SOM is in charge of the project. The primary builders are Samsung Engineering & Construction and Besix.
