How about the shimmering, shaking tower in Shenzhen? The videos were scenes out of Godzilla movies. Have to love CCP building codes. And then the reasons given? Changing weather. Winds (less than 20 mph). Subway system. I was waiting for Oceans 11 and the earthquake-inducing machine. A few years ago I spoke with a man whose company was doing the facelift of Sterling Library at Yale University. The safety measures were impressive. He told me that his company studied China for what not to do with respect to construction. Of course, I hope this tower does not come down.
