What is under the poly?
It may be deceiving but it looks like a lot of the rebar is laying on the poly.
There should be two #5's min. in the thickened edges, rebar should have a min. 3' clearance from the dirt.
If you stretch a string line from side to side, what do you have for concrete depth?
I think some areas are requiring prep like this to prevent subterranean (sp?) termites. They've been a problem in Ca. when building over old orchards. The soil is treated, covered and then concrete laid. Don't know about Texas tho...
