It was dig outside of the entire bottom and there was some iron wiring rounded through entire foundation. Didn’t see nor watch what they might have done inside and perhaps (sure) they didn’t do inside at all.

Sounds like the foundation was not deep enough in its original construction, so they dug a second foundation immediately outside and tied them together through rebar (epoxying the bars into the original foundation).
From the pictures, it doesn’t look like the interiors were touched.
-this is only surmising, since I don’t have pictures of the work.
