Why would anyone try to build a 30 story building in just over two weeks?  Because they can! That's why!

Check out this amazing video of 30 stories going up in 360 hours.

Just before Christmas a Chinese  building company, Broad Group, built a 30-story tall hotel prototype in 360 hours.

The same group had already put up a 15-story building in a week earlier in 2011.

Safety, efficiency and earthquake durability are all major factors that seem to be answered in the video.

No matter how you look at it this is amazing considering most of us couldn't build a tree fort in two weeks.
