None of the grounding had been done when we contracted to finish this service. We ran a 1/0 bare copper 15 feet to the 2" copper water main and straight thru the lug to the iron sprinkler main, a #6 to the 2 ground rods just outside, and another 1/0 thru the 3/4 EMT(10 foot length) to the building steel. The EMT exits the panel thru an EMT connector and the 1/0 protrudes out the top of it for 5 feet before reaching the lug.
If it seems worth it I can simply loosen up the 1/0, slide a connector on to the EMT and add a grounding bushing. Are you saying a piece of #6 out of the panel running up adjacent to(not inside of) the EMT and connected to the grd bushing would make this a better install?
BTW, Gfretwell's comment on the skinny ground in the AC cable was very interesting to me, never knew that.
