A couple of items: It sounds like your specs passed inspection, so you must be right. I have been concerned about trying to ground a lightning strike through rebar, it seems to me the concrete could erupt with violence. I like the idea of multiple grounds but most experts recomend one and only one ground point to avoid large ground currents in storms. Perhaps the important part of that scheme is to make the tie point at the panel?
