The construction of what will be the world’s tallest building is set to begin in Dubai, United Arab Emirates. The building contract was awarded to a consortium led by the South Korean Samsung Corporation on Thursday.
The Burj Dubai tower will stand 800 metres tall – just 5 metres shy of half a mile – once completed in 2008. That will be a full 350 metres taller that the tallest floored in the world today, the Petronas Towers in Kuala Lumpur.
The new tower’s unique, three-sided design will ascend in a series of stages, around a supportive central core and boast a total of 160 floors, accessible via a series of double-decker elevators. Its shape will be integral to its impressive size. The design is intended to reduce the impact of wind and to reduce the need for a stronger core – allowing for more space – as it ascends.
“It’s almost like a series of buildings stuck together,” says Mohsen Zikri, a director at UK engineering consultants Arup. “As you go up you need less and less lifts and less core.”
