Broad Group constructs 30 storey building in only 360 hours

Now this is just amazing! A 30-storey, 17,000m² hotel built in just 15 days!

Chinese construction company Broad Group erected the structure near the Dongting lake in the Hunan Province, China.

The building uses prefabricated modules (with a +/- 0.2mm precision in the fabrication process) mounted on a steel structure, with diagonal steel bracing.

According to Broad, the hotel can resist a magnitude nine earthquake, as tested by the China Academy of Building Research (refer 1.49min).

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 15cm-thick glass curtain wall insulation and four-paned windows with built-in shades, a heat recovery system and three-stage filtration air conditioning process that purifies indoor air to be 20 times purer than the air outside.
