This document is a technical engineering drawing for the Glenn Eller Shaft Closure Project (CW 2025-015-006), located at coordinates 34.93259° W, -95.67094° N. The drawing provides detailed specifications for a concrete pad and stem wall construction, with specific requirements for concrete and steel reinforcement. Key technical specifications include a 4,000 psi Type II concrete mix, ASTM A615 Grade 60 steel rebar, a 4-inch reinforced slab with #4 rebar at 12" on center in both directions, and a stem wall with specific reinforcement details including 4 #4 bars in the long direction and 18" spacing in the short direction. The drawing indicates dimensions of 20' x 16.5' with a 13' x 8' existing shaft opening, and includes a detailed stem wall section showing 24" vertical and 6" horizontal lap distances for dowels. The drawing also notes that false work design is to be provided by the contractor and all dimensions must be field verified.
