Shop Foundation Plan Drawing - Grid C3-C21, S-2 Section Callouts & Dimensions

This scan is a portion of an architectural/structural foundation plan drawing (site-labeled as part of a 'shop foundation drawing' set) that was uploaded to a 1995 Ford Bronco gallery, but it contains no automotive content. The sheet shows a plan view of a building foundation with a rectangular grid of column/gridline callouts labeled C3 through C21 running along the top, bottom, and right edges. Dashed lines indicate footings or grade beams beneath the slab grid. Several section cut markers reference details on sheet S-2, including sections A, B, L, and M. Overall dimensions are given along the right edge: 8'-6 1/2", 52'-5 1/2", 9'-1", and 12'-0", the last apparently for a lower rectangular slab or apron area spanning roughly gridlines C5 to C14. Handwritten field notes in ink mark a location near gridline C8 as 'rebar,' call out a 24" dimension between tick marks, and note the slab or wall there is '8" thick.' A reader can learn the grid layout, section references to sheet S-2, key overall dimensions, and the annotated rebar location and slab thickness. No title block, date, or vehicle applicability information is visible.
