Chinese builder touts “three-floors-a-day” pace

by |
The skyscraper construction sector might be entering a new phase of heightened competition, as a Chinese prefab building company has thrown the gauntlet with its latest project.
Erected at a dizzying pace of 3 floors per day, the 57-storey Mini Sky City in Changsha, Hunan province was completed in just 19 days. The earthquake-proof structure houses approximately 800 apartments and office space for 4,000 tenants.
Construction firm Broad Sustainable Building claimed that this success has made them the world’s fastest builder. A popular time-lapse video now circulating in Chinese streaming sites demonstrated the modular method the company used for the glass-and-steel building’s construction.
“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 told the Associated Press. “This is definitely the fastest speed in our industry.”
Before starting the construction, the firm fabricated the skyscraper’s 2,736 modules over a period of four and a half months.
Experts noted that industry players should seriously consider and invest in developing modular construction as a safe and reliable building option, although it has its limitations.
“[It] is not perfect, and it does not meet all kinds of personalised demands. People nowadays want more personalised architecture,” Arup Beijing associate director Liu Peng said.
Broad Sustainable Building said that it is aiming to complete its next project—Sky City, projected to be the world’s tallest skyscraper at 220 storeys—in just 90 days, once authorities give their approval.

    Not entirely convinced that I'd want to buy into that building.

    Nor stand anywhere near it, for that matter.

    This is interesting. Modular construction has been around for a long time, and it has been proven to be an excellent building method.

    The advantages are that the components are built in a controlled environment. The results are buildings that are more "plumb" which means less room for errors during the assembly.

    This is the future of construction. Reduced construction costs and faster assembly means developers can build more in a year, thus making more $.
