The plans you get when you buy a building rarely show what is actually underground.
We had a parking lot drain back up after a heavy rain. The plans showed a straight pipe going to the street connection. Once we sent a camera through the line, we found an old brick basin buried under the grass and packed with years of dirt and leaves.
We had to bring in a vacuum truck to flush out the pipe and clean out the old basin.
You do not see these things on a spreadsheet. You find them when weather tests the site, and you have to deal with them before the pavement starts to fail.
