Broad Sustainable Building (BSB) is claiming to be the fastest builder of the world after finishing the construction of a 57-story skyscraper at the Hunan provincial capital of Changsha in China in just 19 days.
Xiao Changgeng, the vice president of BSB, said the company built the glass-and-steel "Mini Sky City" at a speed of three floors per day, according to The Times of India. The goal for the construction firm was to build a skyscraper of 220 floors in only three months.
The first 20 floors were completed last year. The company had to stop due to winter weather before proceeding with the remaining 37 floors that were built from Jan. 31 to Feb. 17 of this year.
BSB engineer Chen Xiangqian said that while other construction companies go for the traditional method of building a skyscraper brick by brick, BSB used the modular method, wherein construction is done by assembling the building, block-by-block. This method of construction is already used in other countries like the U.S. and U.K.
The high-rise has 19 atriums, office space for 4,000 people and 800 apartments. It's developers also claim the building is earthquake-resistant, according to the New York Daily News.
Technicians spent five months fabricating 2,736 modules before the actual construction began.
A time-lapse video of the rapid assembly of the "Mini Sky City" project is a hit around Chinese video-sharing sites.
