Great/Scary article. Has anyone worked in the tilting building? Are there cracks in the walls? Is the soil compaction expected to stop (some max density type thing)? I think they stopped the tower of Pisa tilting by injecting concrete under it. It must be difficult to not exasperate they problem at the start of the injection (I am guessing they have to remove some material first).
I knew someone who lived in the building, and while she didn't report cracks in the walls, she did say that things would reliably roll toward one corner of her apartment if they weren't secured.
Sorry, you are the one with the wrong math. The building is out 14 inches at the top. You divide that by the height to get the angle. What you calculated is the lean for a building which sank 14 inches on one side. That would be way worse - an excursion of [edit] 6 feet at the top.
