China has embraced the challenge of putting up the world's tallest building in only 90 days. The 838-meter skyscraper, dubbed Sky City, is set to house 17,400 people as well as a hotel, a hospital, several schools, offices and apartments.
Construction workers from the Broad Sustainable Building company are expected to build at a rate if five stories a day to meet the deadline. To speed the process up, they will reportedly use the 'prefabrication' technique in which blocks of the building are constructed offsite and then pieced together.
The skyscraper, located in Hunan Province's capital Changsha, will feature over 100 high-speed elevators, and is expected to be able to withstand a magnitude 9.0 earthquake.
When completed, the building will be 10 meters taller than the Dubai landmark Burj Khalifa, the world's current tallest building, which took five years to build. China's Sky City is set to cost half as much as the Burj – about $630 million.
China-based Broad Sustainable Building will employ several thousand workers for the ambitious project. The company has already built 16 structures in China, including a 30-story hotel constructed in 15 days.
