Thanks.

The base is the existing concrete floor in my garage. It's been there for A long time so earth would be compacted. I doubt it's 200mm thick. I might drill a section to check. I don't have luxury right now of cutting it and boring a deeper hole so just going to set it to the existing garage floor with wide flange and see how I go.

Probably just get welding shop to weld some 30mm thick square plate to bottom of pipe and set this square plate onto existing concrete. If it's not stable enough then I will have to rethink. It's fairly well out of wind the pier below roof line of rolloff roof.
