The making of Burj Dubai :
The making of Burj DubaiClick to open spoiler!
The world’s most ambitious cities have always had something of an edifice complex. Last century there was the fabled rivalry between New York and Chicago to build the boldest and biggest skyscrapers. Now the action has shifted to prospering metropolises in economically dynamic Asia and the currently cash-flush Middle East. In late January the South Korean business hub, Busan, announced plans to erect a 560m (1,837 ft.) tall skyscraper complex dubbed the Millennium Tower World Business Center that will be the tallest building in Asia when it’s completed in 2010 or 2011.
Yet the true bragging rights for the world’s mightiest mega-structure (currently Taiwan’s Taipei 101 building) will soon belong to Dubai in the United Arab Emirates, where the 800 m. (2624 ft.) Burj Dubai is expected to be completed in November, 2008. Designed by U.S. architectural firm Skidmore, Owings & Merrill, it will house 39 floors of hotel space, 64 floors of apartment units, and 37 floors of office space. Here’s a quick look at how this trophy tower is going up, built by a consortium led by prime contractor Samsung Corp.
Monster Foundation
The 800-meter (1,827 feet) Burj Dubai will need the mother of all foundations to support a super-structure that is expected to weigh 500,000 tons. The tower will rest on a 3.7m-thick triangular frame foundation supported by 192 rounded steel piles or support cylinders measuring 1.5m in diameter and extending 50m (164 ft.) below the ground.
Quake Proof
High-strength concrete is used to help achieve stability in this ultra-high structure. The Burj Dubai is designed to withstand an earthquake (unlikely in this seismically quiet part of the world) measuring up to six on the Richter scale. It will also hold steady during severe winds of up to 55m per second, which the office workers in the clouds won’t sense at all.
Eye in the Sky
To ensure the structural stability of the Burj Dubai during construction, the tower’s vertical and lateral movements are tracked with the help of a satellite-based global positioning system. During construction, any change in load distribution of the building is closely monitored in real time through the use of more than 700 sensors embedded in its structure.
Super Cranes
On the uppermost finished floor on the Burj Dubai, three giant tower cranes have been installed to lift vast amounts of construction materials quickly where they are needed.
That Sinking Feeling
A building of this size (remember, this structure weighs 500,000 tons) has a tendency to sink, if ever so slightly. So each floor is constructed an average of 4mm higher than the designated floor height.
Hedging Bets
To make sure the Burj Dubai is the highest on the planet, the tower is topped with a spiral structure that extends from the 700 meter mark. To get it up there, blocks for the base of the spiral are actually assembled within the building. Then, the spire pipe is lifted up by hydraulic jacks with the help of steel cables.
