In my part of the world as of jan. 2007 all new construction must have a piece of the rebar brought above grade, it must be tied to the bar in the footing/slab,and must be bonded to the GEC or the electrode itself with no smaller than a 6 awg solid copper wire by approved clamp or CAD weld. I have to do one tomorrow for a garage addition on the opposite end of house from service, 85 feet away. Homeowner will not be happy!!
