Thanks Peter! The concrete pad will be ~200mm above ground height so I am planning on doing a separate foundation for the pier -thinking 800x800x1200-1500 or so with wire cage, and just forming the top 200-300, so the base of the pier foundation has good contact with the undisturbed soil. I will try to get the concrete as smooth as possible and drill some anchors for the steel pier. Still deciding if I use some washers if I need to shim the pier or I have seen a block of treated ply used under the pier which is compressed down…
The rest of the slab will be separate, maybe with some slightly deeper foundations at the corners to help keep it level. I will run some conduits through the floor slab and the pier foundation for cable management. This is my first obs so any tips much appreciated. 👍👍
