Lift manufacturer's specs for concrete thickness and strength vary. I've seen 9-10k lb 2 post overhead lifts spec anywhere from 4" 3000psi to 6" and 3500psi.
If you have not poured the slab yet, have the part near the lift made thicker just to be sure.
There is also a spec for how close the lift bases can be to cracks and control joints and the edge of the slab. Plan accordingly with the concrete contractor.
Overhead two post lifts will need a minimum of 12' ceiling. Not all fit under 12'. I've done some modeling and I think I can get a full sized truck up high enough for a 6' person under a 12' ceiling if there's nothing in the way like lights or garage door opener. The door rails will have to be close to the ceiling and the sectional door can't go as far as the cab of the truck 'cause there will be only a few inches to spare. Going to 12.5 or higher would make that easier.
