Not sure what the structures in the holes are for.
They were drilled and I can't recall if they were filled with a re-bar cage or just a I beam before the concrete was placed. They were covered with a tarp and heated for a few days and then the hole was backfilled with some of the clay they were taking from the other side of the pit and run over a few times with the loader to tamp them.
As soon as the rain came they started to turn into sinkholes and got the cone protection.
