Burj khalifa's grand vision


World's tallest building. A living wonder. Stunning work of art. Incomparable feat of engineering. Burj Khalifa is all that. In concept and execution, Burj Khalifa has no peer.

More than just the world's tallest building, Burj Khalifa is an unprecedented example of international cooperation, symbolic beacon of progress, and an emblem of the new, dynamic and prosperous Middle East.

It is also tangible proof of Dubai's growing role in a changing world. In fewer than 30 years, this city has transformed itself from a regional centre to a global one. This success was not based on oil reserves, but on reserves of human talent, ingenuity and initiative. Burj Khalifa embodies that vision.

Mr Mohamed Alabbar, Chairman, Emaar Properties, said: "Burj Khalifa goes beyond its imposing physical specifications. In Burj Khalifa, we see the triumph of Dubai's vision of attaining the seemingly impossible and setting new benchmarks. It is a source of inspiration for every one of us in Emaar. The project is a declaration of the emirate's capabilities and of the resolve of its leaders and people to work hand in hand on truly awe-inspiring projects.

Emaar had but one inspiration, the unflagging enthusiasm set in motion by His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, who inspires us to reach for the stars.

Burj Khalifa, formerly known as Burj Dubai, is a skyscraper in Dubai, United Arab Emirates, and is currently the tallest man-made structure ever built, at 828 m (2,717 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.The building is part of the 2 km2 (490-acre) flagship development called Downtown Burj Khalifa at the "First Interchange" along Sheikh Zayed Road, near Dubai's main business district.

The tower's architecture and engineering was performed by Skidmore, Owings, and Merrill of Chicago. Adrian Smith, who worked with Skidmore, Owings and Merrill until 2006, was the chief architect and Bill Baker was the chief structural engineer for the project. The primary contractor was Samsung C&T of South Korea, who also built the Taipei 101 and Petronas Twin Towers. Major subcontractors included Belgian group Besix and Arabtec from the UAE. Turner Construction Company was chosen as the construction project manager. Under UAE law, the Contractor and the Engineer of Record are jointly and severally liable for the performance of Burj Khalifa. Therefore, by adoption of SOM's design and by being appointed as Architect and Engineer of Record, Hyder Consulting was legally the Design Consultant for the tower.

The total cost for the Burj Khalifa project was about US$1.5 billion; and for the entire new "Downtown Dubai", US$20 billion. Mohamed Ali Alabbar, the Chairman of Emaar Properties, speaking at the Council on Tall Buildings and Urban Habitat 8th World Congress, said in March 2009 that the price of office space at Burj Khalifa had reached US$4,000 per sq ft (over US$43,000 per m2) and that the Armani Residences, also in Burj Khalifa, were selling for US$3,500 per sq ft (over US$37,500 per m2). The completion of the tower coincided with a worldwide economic slump and overbuilding, causing it to be described as "the latest ... in [a] string of monuments to architectural vacancy."
