With several successful lightning-fast builds in the last few months, China is ramping up its prefab-enabled building process – in a big way.

Hunan-based Broad Sustainable Building has a plan to overtake the Burj Khalifa in Dubai in a mere 90 days with its 838-meter, 220-story Sky City tower planned to break ground in November of this year. As if the height wasn’t impressive enough, the firm plans to complete the project in a mere three months, with opening day planned for January, 2013.

The Burj Khalifa took over five years to complete, at a cost of over $1.5 billion. How, then, can BSB possibly build a vertically-superior structure for a mere $628 million and in a fraction of the timeline? The answer lies in the firm’s unique building process, which incorporates heavy pre-fabrication. Over 95 percent of the Sky City tower will be completed before any ground is broken at the site, meaning assembly of the structure can be achieved in a short time-frame.

In an ironic twist, China’s upcoming super-tower has a Dubai-based architect, and will provide occupants with over one million square meters of usable space, connected by over 100 elevators.
