57-storey skyscraper built in just 19 days
A Chinese construction company is claiming to be the world's fastest builder after erecting a 57-story skyscraper in 19 working days in central China.
The Broad Sustainable Building Co. put up the rectangular, glass-andsteel Mini Sky City in the Hunan provincial capital of Changsha using a modular method, assembling three floors per day, company vice president Xiao Changgeng said.
The company, which has ambitions to assemble the world’s tallest skyscraper at 220 floors in only three months, worked on Mini Sky City in two spurts separated by winter weather.
Its time-lapse video of the rapid assembly has become popular on Chinese video-sharing sites since it was first uploaded on YouTube. “With the traditional method, they have to build a skyscraper brick by brick, but with our method, we just need to assemble the blocks,” company engineer Chen Xiangqian said. Such modular approaches have been used for highrise apartment blocks elsewhere, including in Britain and the US.— AP
