.Burj Khalifa , known as Burj
Dubai prior to its
inauguration, is a skyscraper in Dubai, United Arab Emirates, and is the tallest man-made structure in the
world, at 829.8 m (2,722) ft).
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,and is part of the new
2 km2 (490 acres)
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.The
primary contractor was Samsung
C&T of South Korea.
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).He estimated the total cost for the project to be about
US$1.5 billion.
The project's
completion coincided with the global financial crisis of 2007–2012, and with
vast overbuilding in the country; this led to high vacancies and foreclosures. 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.
Because of 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, 825 were still empty at that time. However, over the next two and a half
years, overseas investors steadily began to purchase the available apartments
and office space in Burj Khalifa. By
October 2012, Emaar reported that around 80% of the apartments were occupied
