Burj Khalifa ( Arabic : " Khalifa
Tower"), [8] known as Burj Dubai prior to its
inauguration, is a skyscraper in Dubai, United
Arab Emirates, and is the tallest manmade
structure in the world , at 829.84 m (2,723 ft).
[3][8] Construction began on 21 September
2004, with the exterior of the structure
completed on 1 October 2009. The building
officially opened on 4 January 2010, [1][9] and
is part of the new 2 km 2 (490-acre) flagship
development called Downtown Dubai at the
'First Interchange' along Sheikh Zayed Road ,
near Dubai's main business district. 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. [10][11] The
primary contractor was Samsung C&T of South
Korea .[12]
The total cost for the project was about US
$1.5 billion; and for the entire "Downtown
Dubai" development, US$20 billion. [13] In
March 2009, Mohamed Ali Alabbar , chairman of
the project's developer, Emaar Properties, said
office space pricing at Burj Khalifa reached US
$4,000 per sq ft (over US$43,000 per m²) and
the Armani Residences , also in Burj Khalifa, sold
for US$3,500 per sq ft (over US$37,500 per
m²). [14]
The project's completion coincided with the
global financial crisis of 2007–2010 , and with
vast overbuilding in the country, led to high
vacancies and foreclosures. [15] With Dubai
mired in debt from its huge ambitions, the
government was forced to seek multibillion
dollar bailouts from its oil-rich neighbor Abu
Dhabi . Subsequently, in a surprise move at its
opening ceremony, the tower was renamed
Burj Khalifa, said to honour the UAE President
Khalifa bin Zayed Al Nahyan for his crucial
support. [16]
Due to the slumping demand in Dubai's
property market, the rents in the Burj Khalifa
plummeted 40% some ten months after its
opening. Out of 900 apartments in the tower,
around 825 were still empty at that time. [17]
