I took off work early to meet the cement truck in the afternoon. Original calculation was 5 yards. Was short one yard, but lucky to have a nice enough truck driver (out of Rockdale) to fetch another yard. One stick of rebar was centered in each footing to extend up into piers (8’x8′ hollow cement blocks). Enough play in the blocks to accommodate “eyeing” placement of the rebar at concrete pour.
Holes for the 30 footings were drilled to a depth of 4′. A 12″ bit was used, mounted to the back of a small tractor. Work began in the afternoon and continued until about 9 PM, quickly earning my popularity with the neighbors
