The excavation would involve extending the driveway about 80 yards further into the property and digging the down 12" to lay different layers of material to allow for drainage. Apparently the ground in this area of the property is one big gravel pit, and it drains exceptionally well. The driveway would be brought up to alevel of 2" above normal grade.
The excavator dug the foundation out for footers to support a 24'x36' structure.
The concrete contractor poured 8 inch by 16 inch footings with 1/2 inch pins every 4 feet. The walls are 8 inches thick with two rows of steel reinforcement and walls at 5 feet high, stepping the foundation walls to accomodate the grade. At this point, the excavator was running behind schedule. The concrete job was planned to conclude by the end of June and the footers were only poured on the 26th.
There are two steps to the side walls, the first is 16 inches and the second step is 20 inches for a total of 36. The floor would be poured later at 4 inches thick with fiber mesh reinforcement and swacut expansion joints. The walls were formed up and poured on June 29th.
To backfill the foundation walls, fill was compacted and brought to level so the concrete floor could be poured at a later date on the inside. The excavator was slowing the project down, starting work late in the morning and not working very long in the day. By June 30th we were supposed to be able to frame up the walls. We had to wait until the excavator filled in around the foundation walls, a job he never totally completed until after we had the entire structure built up--and even then it wasn't a satisfactory job. We had to correct it ourselves later.
