"THE fact that the Chinese can put a building together quickly is not news. But the fact that teams working near Dongting Lake in Hunan province can assemble a prefabricated 30-storey hotel in 15 days is rather impressive, as this time-lapse video demonstrates. Work done on building the foundations—and indeed on fabricating the various sections used to create the hotel—were not added to the video's timing, so the claim to a 15-day construction period should not be taken too seriously. Writing on Treehugger.com, Lloyd Alter is awed by the way the building was put together.
When I was a kid I used to play with systems like this, but never thought that they would actually become real some day. The implications of this are significant; construction is just about the only industry that has not been exported. But now the Broad Sustainable Building Corporation has designed a system that will let them build anywhere, to construction tolerances of +/- 0.2 mm. The architectural and construction world just changed.The hotel is the creation of Broad Group, an air-conditioning specialist, which says that the building can withstand an earthquake of magnitude 9. And its construction cost, according to Next Big Future, is one third of the current standard for Chinese skyscrapers. You may be seeing more of them."
