Last month I was serving on a team while they were deciding to invest in a building. One gentleman, who was a retired coalmine engineer, took it upon himself to run a study to find out what was under the building. I was fascinated to learn that others had plotted out layers of soil and rock thousands of feet below. His concern, of course, was that one day someone could dig under the building, which could affect the structure itself.
