Instead of demolishing Shanghai's 85-year-old school, engineers gave it mechanical legs and walked it 62 meters across town, rotating the 7,600-ton structure like a chess piece into its new position.
A five-story school built in Shanghai in 1935 stood in the way of a new office complex, so engineers dug underneath it and fitted 198 mechanical supports; over 18 days they walked the 7,600-ton building 62 meters and rotated it 21 degrees onto its new site.
