In China, a 30 story hotel has been built in 15 days.
The time lapsed footage is below.
It was erected near the Dongting lake, in the Hunan Province, China, by Broad Group, a Chinese construction company specialised in sustainable architecture. The building uses prefabricated modules (with a +/- 0.2mm precision in the fabrication process) mounted on a steel structure, with diagonal steel bracing.
The hotel is so solid that it can resist a 9 magnitude earthquake, as tested by the China Academy of Building Research (there’s a scene in which you can see the testing process, at 1:49). They claim this is five times more earthquake-resistant than conventional buildings.
The company also says that it is five times more energy efficient, with 6-inch thick glass curtain wall insulation and four-paned windows with built-in shades, a heat recovery system and 3-stage filtration air conditioning process that purifies indoor air to be 20 times purer than the air outside. They even have air quality monitoring in every room which, given the pollution problem in China, seems to be an important selling point there.
That info seems to come from the company that built it so, you know, grain of salt.
Still, it makes me think about the thirty foot length of side-walk near my home. It’s been under repair for about a year now.
