Footings F-1 and F-2 are depicted with their respective dimensions and rebar configurations, including #4@6″C/C grid reinforcement. The foundation design accommodates different site conditions with specific notes about backfilling procedures for situations where road level differs from natural surface level (N.S.L.) by more than 5 feet. Concrete specifications for PCC (1:4:8) and DPC (2″ thick) are indicated, with vertical DPC (3/4″ thick) at the interface between inside and outside faces. The drawing includes elevation references with finished floor level at +2′-0″, porch level at +1′-0″, and road level at ±0′-0″.
