Haters gonna hate, but this is some engineering marvel. A developer in China has built an entire 57-storey building in just 19 days and as this time-lapse video shows, the Mini Sky City building was put up brick by brick at a rate of three full storeys a day in Changsha, the capital of Hunan Province in south-central China.
Broad Sustainable Building has claimed that the new tower’s interiors will feature 99.9 percent pure air because of the tight construction method used and its built-in airconditioning system, addressing China’s worsening air pollution problem.
Using prefabricated modules also reduced the need to transport concrete by 15,000 trucks, according to the Broad group, while the tower’s quadruple pane glass can save “12,000 tons of CO2 emission compared to a building of the same size and use.”
To see is to believe. Here’s a promotional video clip of how the builders handled the tower’s super-speedy construction.
