How fast do you think it takes to build a skyscraper? A Chinese construction company called Broad Sustainable Building (BSB) has built a 30-story building in just 15 days.
And this time lapse video may be an example of how they might succeed in their next plan: they want to build the world’s tallest building in 90 days.
When completed, the planned 220-story pre-fabricated building would be 838 meters (2749 feet 4⅛ inches) tall. That’s over 10 meters (or around 32 feet) taller than Dubai’s Burj Khalifa, the current tallest building in the world. Time it took for the Burj Khalifa to be built: about 5 years.
