I don't have an obs but I have a pier with about 1.5 cubic metres of concrete and reo under it in a pyramidal shape with a base of 600x600 about 1m deep. When I walk around the pier in the grass, it's enough to throw the guiding. So no matter how big your slab here, I'm pretty sure it will transfer to the pier when you walk around if it's integral to the slab. I'd make the pier footing thinner and deeper, with a gap in between its edges and the slab.
