When completed by the end of next March, Sky City in Changsha will be the tallest skyscraper in the world, standing at 2,749ft (838m) high, over 220 floors. And remarkably, they’ve not started building it yet.
It took Dubai more than five years to build the world’s tallest building, the 828m Burj Khalifa, but architects and engineers at Broad Sustainable Building (BSB), a unit of the air conditioning maker Broad Group, are confident they can beat that record.
BSB senior vice-president Juliet Jiang told Construction Week Online that the company’s plan to construct the skyscraper “will go on as planned with the completion of five storeys a day.”
Designed by engineers who worked on the Burj Khalifa, Sky City will achieve the target by assembling BSB’s 95 per cent prefabricated modular technology at a breakneck construction pace. Nine of the world’s newest tallest 20 buildings are being built in China.
Adrian Smith, the Chicago-based designer of the Burj Khalifa who is working on the Kingdom Tower in Saudi Arabia, said at a meeting of the Council for Tall Buildings and Urban Habitat in Shanghai last month that rapid urbanisation in China would fuel major expansion in tall buildings.
“There are 179,000 people moving into urban areas every week. Do they go into a horizontal or a vertical city? It’s a question of economics,” said Mr Smith.
BSB, currently responsible for 20 modular structures in China, demonstrated the construction method to a wider audience in January, when it constructed a 30-storey hotel in 15 days.
