Your biggest worry should be the P.T. strands (besides the rebar). I presume you requested Pacometer readings to establish the location of the strands and rebar. For safety reasons I suggest to use 2" clear between the edge of the cores and and the strands.  I am talking about an elevated strcutural slab, but I would use the same precaution for a post tensioned slab on grade.
Thank you. Yes, the entire area has been x-Rayed. We know exactly where every piece of reinforcing is.
