(CNN)


Chinese construction workers awed the world by erecting a 30-story prefabricated hotel in 15 days, or 360 hours.

The T30 hotel in Xiangyin country, Hunan province was constructed in 2011 by Broad Sustainable Building(BSB), a Chinese construction company renowned for its eye-opening efficiency.

The five-star hotel covers an floor area of 17,000 square meters and features 450 rooms.

It was constructed with a new structural system called “sustainable buildings” designed and developed by BSB. A simulation model of the building withstood aseries of earthquake resistance tests -- from 7.0 to 9.0 in magnitude --conducted by China Academy of Building Research in May 2011.


BSB is unconcerned about doubts regarding the quality of buildings erected within such short time frames, said Jiang Yan, senior vice president of Broad Group, BSB's parent company.


"It's because people don't understand [the technologies used for the building]," she said. "Let time prove everything."

Timing is too quick questions of quality are being asked

Please answer this question:
"It was designed and ... by BSB."

Who or what is "BSB"?

Could be the name of the developer. Just curious.

They prefab the floors in their construction facilities and ship them to the site, putting the buildings together like a series of Lego building blocks. It is fairly efficient, but their designs are not very imaginative because the precision required for all of the connections in each prefabbed unit (electrical, water, sewage,etc.) do not leave very much room for creativity.

I do see practical applications for this technology, especially in the area of disaster relief, however, it would require having a large number of these units built and placed in storage facilities for future use. They wouldn't be able to do these buildings on an as-needed or emergency basis because of the time constraints involved in concrete curing, as well as constructing each prefab section.
