This is the way. I do this day in day out with geo's and structural firms. Depending on what finding they arrive at will determine the scope. This could turn out be a very costly build. Without any information of your situation I could loosely suggest that you wall off the slab edge with a standard exterior envelope if you can justify the that the slab square footage will benefit what you're after.
