Penetrations for pipes running perpendicular to concrete grade beams and footings at various vertical alignments relative to the reinforcing steel. Pipe sleeves are specified with an inside diameter two inches larger than the pipe outside diameter or bell outside diameter, and the void is sealed with an elastic waterproof material. Top bar adjustments feature standard hooks and side bars with size and number matching the main reinforcement, supplemented by additional number four stirrups at each side. When pipes pass below the footing, the assembly incorporates specific backfill compaction requirements or stepped footing configurations depending on the depth.
