No screen and minimal rebar in the floors, they typically pour a single slab, including the garage floor, on top of plastic sitting on a layer of clay.
The concrete includes granite aggregate which is much stronger than limestone and allows then to start building block walls a couple of days after pouring the slab.
A hammer drill and concrete lag bolts can be used secure the safe.
There are water and sewer lines under the slab so don't drill more than 4" deep.
