I'm wildly guessing the building dates to around the 1970's. For reasons I don't understand the GPR person was very dismissive of the possibility that a review of the blueprints would adequately address the problem. From what I read, "post-tension cables" seems like a significant potential issue; I don't have a sense of whether there'd be another way to determine their location.
