And then there is the story of Ramp J near King of Prussia. Ramp J was part of a project to move cars from US 422 I-76. It was to be built on nice solid ground. Unfortunately, the earth sank underneath it, resulting in huge holes. The engineers said "Oh, just dump some grout in and continue". They did. The holes just kept on coming. Eventually the engineers decided to build a grout-making plant on site, and many thousands of tons of grout were poured into the ground -- along with many millions of dollars, overrunning the budget for the project and delaying it enormously.

The moral of the story is "don't hire the man from Qi to estimate sinkhole impact"
