So I took over a school job a few months back. After speaking with the inspector he mentioned that a grounding electrode is required in the new addition to meet a code requirement of "as available". The foundation was installed before I started this gig so apparently I have to go back and make an irreversible connection to the rebar. Do you guys have any tips or timesavers that will work better than getting out a shovel and jackhammer? Any advice would be greatly appreciated.
 
Check the print to be sure the footing is in direct contact with the earth.
See footing detail for any isolation that would keep it from being used as a electrode for the new service
If not jack hammer.

Presuming the addition is still part of the existing structure.

It would only be required if there is no other CEE. If the existing structure has a CEE already, you would not be required to bond it to the CEE of the new structure as you are only required to use one CEE if more than one are present in the same structure.
 
Perhaps there are plans on existing. There are rebar locators. A chipping hammer would be the way to expose the rebar
 
if you can verify if the anchor bolts are tied to a horizontal rebar you may be ok to connect gec to an anchor bolt
