Burj Dubai
Burj Dubai in the United Arab Emirates is now the world’s tallest man-made structure, after reaching a record height of 688 metres, The tower is now over 160 stories - the largest number of floors in any building across the world, its developer real estate giant Emaar Properties said in a statement.
The tower unofficially became the world’s tallest man-made structure in April, 2008 after surpassing the KVLY-TV mast (628.8 metres) in North Dakota in the United States. Though the final height of the tower has not been disclosed yet, it is expected to reach 800m. It will be officially recognised as the world’s tallest structure only when the construction is fully completed.
The tower was designed by Chicago, Illinois-based Skidmore and is being constructed by high-rise building experts from South Korea’s Samsung Engineering & Construction, Belgium's Besix and United States Turner Construction.
Burj Khalifa (Arabic: "Khalifa Tower"), 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).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-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. The primary contractor was Samsung C&T of South Korea.
The total cost for the project was about US$1.5 billion; and for the entire "Downtown Dubai" development, US$20 billion.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).
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. 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.
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.

Skyscraper. Is tall, the building of housing on an ongoing basis of several floors, usually dedicated for
office use and trade. There is no formal definition or high above and can be classified as building a skyscraper. One common feature is the presence of a steel frame which is suspended curtain walls, instead of bearing walls of conventional construction.In context, could be considered relatively small building a skyscraper if it highlights the much higher than the built environment and change the horizon of the year.
Progress has been made in the maximum height of structures with historic construction methods and
technology. Also lacked a formal definition, originated 'Supertall "is the current generation of high-rise
buildings on an exceptional basis.Has applied for the first time the term "skyscraper" on the buildings of
steel construction framed of at least 10 storeys in the late 19th, as a result of surprising the public in
high-rise buildings being built in major cities such as Chicago, New York City, and Detroit, and St.. Louis. and a framework of steel and was the first skyscraper in the Home Insurance Building (originally
10 storeys high with 42 m or ft 138) in Chicago, Illinois in 1885. Some point to a building in New York
just seven floor to life insurance, which was built in 1870, as a skyscraper in the early use of an innovative type of the framework of the skeleton, but this appointment depends largely on what factors are selected.Scientists make the argument even find it to be purely academic.
