We are starting to inspect for the Ufer ground. 250.52 The Code requires 1/2 inch rebar. If the contractor uses 3/8 inch rebar do we ignore it, and go back to just using a ground rod and water plus Building steel when available. Some contractors around here just float pieces of rebar into the concrete and don't tie wire them together or have them raised up on chairs. Alan--
Were you actually around in the 20's? I can remember things from when I started out, and have heard about others. Have you ever tried to update an older home originally wired with all rigid conduit?
I suppose there are places where rebar in the footer is not required but it is one of the major inspections in the Florida Building Code. It has to be #5 or larger, tied and up on chairs.
