I am building a 200,00sq ft warehouse in California with a 2000 amp service panel. My electrician failed to get his UFER ground wire tied into the footing rebar before we poured the footings. This is a concrete tilt-up and the pour back at the walls will be another foot with rebar all the way around. The first part of the footing is 1'-6" deep with continuous #4 rebar. There are #4 slab dowels 12" o.c. that are tied to the continuous footing rebar in 3 places. If I added 20' of #4 rebar tied to these and tied #4 AWG to that also and poured these in my closure strip would that work?
