Had some time to think about the pad and it "could" be on a pile but as there is no dirt around it I find it quite unlikely. Based on the amount of dirt around the house supports they didn't go into the ground very deep. But they could have cleaned up the considerable amount of mud that would have come out of each hole they would have drilled for each post. I don't see any bobcat tracks used to haul the mud away but they could have used a wheelbarrow. That's a lot of mud from 12-14 holes. Diameter squared X .7854 X length (in feet) or about 1.7 sq yds at 6 feet deep. But maybe there they aren't required to go that deep.
