BillCroasmun,
Thanks, I think that would probably work, just that I am really nervous about picking the whole barn up and undermining, while trying to support it with temporary supports. Thats why I was leaning toward the sunken pylon thing. I could do one at a time, support it on both sides of the digging point remove the existing pier, use PHD, dig in at an angle then move inside and do the same. The ground around the barnshop is really unstable for digging trenches, I dug the trench for the sub panel and the sides just kept collapsing in. Would be a long process as I would have 20 individual concrete jobs essentially.
