Burj Dubai (Arabic: برج دبي "Dubai Tower") is a skyscraper under construction in the Business Bay district of Dubai, United Arab Emirates, and is the tallest man-made structure on Earth, despite being incomplete. Construction began on September 21, 2004 and is expected to be completed and ready for occupation in September 2009.[1]
The building is part of the 2 km2 (0.8 sq mi) development called "Downtown Dubai", at the "First Interchange" (aka "Defence Roundabout") along Sheikh Zayed Road at Doha Street. The tower's architect is Adrian Smith[4] who worked with Skidmore, Owings and Merrill (SOM) until 2006.[5] The architecture and engineering firm SOM is in charge of the project.[4] The primary builders are Samsung Engineering & Construction and Besix along with Arabtec.[6] Turner Construction Company was chosen as the construction manager.[7]
The total budget for the Burj Dubai project is about US$4.1 billion[8] and for the entire new 'Downtown Dubai', US$20 billion. Mohamed Ali Alabbar, the CEO of Emaar Properties, speaking at the Council on Tall Buildings and Urban Habitat 8th World Congress, said that the price of office space at Burj Dubai had reached $4,000 per sq ft and that the Armani Residences, also in Burj Dubai, were selling for $3,500 per sq ft.[9]
Height
Current height
As of September 1, 2008, Burj Dubai had reached a height of 688 m (2,257 ft), with 160 completed floors.[10] Although fan websites report that the tower has risen higher since that time[11], no official height increase has been reported. The Burj Dubai is now the tallest building, tallest freestanding structure and tallest man-made structure of any kind ever built on the planet.

Note: Additional records for tallest skyscraper are considered unofficial. On July 20, 2007, the head of the Council on Tall Buildings and Urban Habitat (CTBUH), Antony Wood, said "We will not classify it as a building until it is complete, clad and at least partially open for business to avoid things like the Ryungyong [sic] project. Taipei 101 is thus officially the world's tallest until that happens."[19]
Projected height
The projected final height of Burj Dubai is officially being kept a secret due to competition from other buildings under construction or proposed; however, figures released by a contractor on the project have suggested a height of around 818 m (2,684 ft).[20] Based on this height, the total number of habitable floors is expected to be around 162. However, Burj Dubai's construction manager, Greg Sang, has said only that the final height would be greater than 700 m (2,297 ft), and that it would be the world's tallest free-standing structure when completed.[21]Comparison
