This is the best looking hole I've ever seen. No gravel in the bottom (of course), so they just sunk the bottom of the solar mounting pole in the dirt.

I tried to convince them that the conduit wasn't supposed to be embedded in the concrete, but they had a side-view drawing where it looked like it did. My showing them a top-view drawing didn't convince them. Likewise, details about trench depth were pretty much ignored.

But that is an awesome hole!
