The company that put up a 15-story building in Changsa, China, in 2 work days back in 2010 — and produced a time lapse video that we posted — is back with word that it erected a 30-story hotel in Changsha in 15 days, finishing just before New Year's Eve.

As before, Broad Sustainable Building laid the foundation before the other work. And of course, there was labor beforehand to produce the prefabricated pieces. But still, 30 stories in 15 days is quite remarkable. Here's the video.

The company says doing allows for "higher precision in fabrication ... more coordinated on-site construction management ... [and] lower construction waste."

We have a question, though:
