Sky City in Changsa: China plans to build world’s tallest tower
By Eddie Wrenn
If you want to reach the top, you have got to move fast.
This must be the logic of a Chinese consortium, who seem confident that they can bend time and space and build the world’s tallest tower – all 838 metres of it – in just three months.
As soon as the 220-storey ‘Sky City’, in Changsa, the provicincial capital of Hunan, is complete, it will take the mantle of the world’s tallest building.
That means it will beat Dubai’s current world-beater, the Burj Khalifa – which took five years to build.
Sky City: The developers in Changsa have an ambitious plan to get the gleaming 838m tower in the skies in just 90 days – prefabricating most of the parts in order to make the self-imposed deadline
90 days to be the biggest in the world: It’s a tall order – but the company thinks it can put other skyscrapers to shame
World’s tallest (for now): The Burj Khalifa, 828m tall, in Dubai
Broad Sustainable Building (BSB), a construction company based in Hunan, believers they can do the whole $ 628million construction in 90 days.
The building will also beat China’s current biggest skyscraper poster – the 632-meter Shanghai Tower.
The project has been given the go-ahead in Changsa, but the central government still need to sign off on the deal.
But if the go-ahead comes, BSB chief executive officer Zhang Yue wants to start building this November – and finish in January 2013.
The company has been quite quiet on the use of the building, but earlier plans in 2010 – when the building was going to be ‘just’ 666m, would be used to home 70,000 to 110,000 residents.
There is a track record for BSB, a previous 15-storey construction was put up in six days in June 2010 – and a 30-storey building in just 360 hours.
The key to their speed is prefabricating large portions of the buildings in factories – so technically most of the tower will be built before the first digger hits the site.
This is similar to some German construction companies such as Huf Haus, who built homes in their factories before constructing them on-site.
The new building will have 104 elevators, one million square metres of floor space, and quadruple glazing.
The tallest building in the world may be built in Changsha, Hunan province
