Metal building counter-poise grounding system at the four corners of the building. What would be the minimum depth? I am looking at minimum 24' including the GEC going to the building steel?
 
Re: GROUNDING

presumably you are talking about burying the gec 24" underground.

i see no reason at all to bury the bond wire to the building steel, unless you have to do so to get to the building steel.

Re: GROUNDING

You need only to provide adequate protection of the grounding conductor from physical damage. This will be a judgment call. Consult your AHJ.
