A Chinese construction company is planning to build the world’s largest skyscraper – and it’ll race against the clock to do it.

Broad Sustainable Building wants to construct a 2,749 feet-tall building, dubbed “Sky City,” over a period of just 90 days in Changsha in Hunan province, China.

It took Dubai over five years to build the current record-holder, the Burj Khalifi, which stands at a whopping 2,722 feet.

Workers will complete five stories a day to build the soaring tower, which will be able to house 31,400 people, the company’s senior vice president told Construction Week Online.

Work on the Sky City’s foundation is expected to kick off next month. But the actual 90-day challenge won’t begin until the start of 2013.

The company’s plans for the 220-story building, of course, have been met with a great deal of skepticism.

Broad is known for its ability to build at a breakneck speed. It put up a 15-story hotel in just 48 hours back in 2010 and a 30-story tower in 15 days in 2011.

However, the company has never constructed a building higher than 30 stories.

Many believe that the construction of Sky City – if Broad can pull it off – is a sign of China’s growing prowess in the technological world.

“It’s a symbol of their new superiority,” Takashi Fujitani, the director of Asia Pacific studies at the Munk School of Global Affairs’ Asian Institute in Toronto, told the National Post.

“Modernity today is really about speed in a lot of ways, so being at the top of the world is about being able to do things fast.”

Nine of the world’s tallest buildings are currently being built in China.
