grounding

We visited an electrical contractor to check on any oddities that we might need to be on the watch for. He said (as I suspected) that the thing will be quite well grounded since it is all welded together and welded to the plates that are set into the concrete piers that serve as a foundation. He did say that we are required to have a ufer ground anyplace that we have a continuous foundation, which would mean the kitchen/living area where there will be a slab. But it is simply a 20 foot piece of #4 re-bar that extends up out of the footing that you can tie into the panel, to connect the whole thing together. Quite simple, really.
