So a while back, the Hunan-based construction company Broad Sustainable Building, who is changing the property development game in China, put up a 15 story building in only 6 days.
They are able to achieve these remarkable speeds by constructing nearly all of the pieces off-site, and then simply plugging them together like Legos when it’s GO time.
Now BSB envisions creating the tallest building in the world. The monstrous “Sky City” would reach 838 meters into the sky, surpassing the current tallest building, the Burj Khalifa, which sits at only 828 meters. Oh, and BSB thinks they can build it in 90 days. In comparison, the Burj Khalifa in Dubai took over 5 years to build.
The structure would include an absurd 220 stories, and dwarf China’s current tallest skyscraper, the Shanghai Tower, which is only 632 meters tall. All this would come at a cost of RMB 4 billion, or US $628 million.
The project is still pending government approval, but BSB is confident it will be granted. Construction is slated to begin November 2012 with completion of the tower in January of 2013.
The $628 million expense is quite small compared to the $1.5 billion the Burj Khalifa and the $2.2 billion the Shanghai Tower cost. Additionally, BSB CEO Zhang Yue claims the new structure would use only a fifth of the energy of a conventional building. This is due to new age construction techniques such as quadruple glazing and 15cm thick exterior walls used for thermal insulation.
