Whats the hurry...?

What can you accomplish in 360 hours?
The Chinese sustainable building company, Broad Group, has yet attempted another impossible feat, building a 30-story tall hotel prototype in 360 hours, after building a 15-story building in a week earlier in 2011.

You may ask why in a hurry, and is it safe? The statistics in the video can put you in good faith. Prefabricated modular buildings has many advantages over conventional buildings.

Higher precision in fabrication (+/- 0.2mm).
More coordinated on-site construction management.
Shorter construction time span.
Lower construction waste.
Also many other health and energy features are included in Broad Sustainable Buildings (BSB)

The building was built over last Christmas time and finished before New Years Eve of 2012.
