No. If you can get a hole drilled vice dug go for it. I was offered
factory made rebar cages suitable for either, take your pick. I chose
square and backhoe over round and drilling as the lowest bid I got on
drilling a 5 ft diameter hole was $2000. Extra concrete due to backhoe
precision was way under $2000. Back hoe cost $80. The drilling folks
wanted me to be liable for any teeth they might break.
