my second question if there offset between beam and post aboveand is hard to get anything addedwhat is acceptable for example 1 1/8 inch plywood3/4 inch plywoodto span 16 inch over joists with point load = 3.0 kip to 5.0 kips?!
you can't add 4x solid blocking in the joist bay with hangers, each end? check the joists for the point load. DO NOT rely on the ply to span with a point load on it.
