China is well known for its mind-bogglingly fast-paced construction, but its latest claim is truly one for the record books.
Sky City, an 838-meter (2,750-ft) building to be built by Chinese construction company Broad Sustainable Building (BSB), of Broad Group, will not just be the tallest skyscraper on the planet, won’t just be “earthquake-proof,” won’t just implement a sustainable design approach – it will go up in only 90 days.
Skeptical? BSB isn’t. They’ve used their building technique (which involves pre-fabricating and assembling up to 95% of the materials in modular form before construction even begins) to assemble a 15-story building in 6 days and a 30-story hotel in 360 hours, CNN reports. As for safety concerns, BSB has built a 30-story prototype that withstood a simulated magnitude 9 earthquake — whether the 220-story Sky City will be as secure remains to be seen, but BSB certainly seems confident.
