A concrete grade beam contains a pipe or conduit sleeve positioned between interrupted top reinforcement bars with additional top bars matching the size and quantity of the interrupted bars. The sleeve maintains a maximum distance of one and a half inches from the top reinforcement and a maximum six-inch clearance, with a lap splice detailed per sheet S5101s. Detail notes specify minimum spacing and clear distance rules for sleeves relative to reinforcing steel, caulking requirements at the exterior pipe interface, and additional shear stirrups required when penetrations occur at rebar splice locations.
