A concrete foundation footing accommodates utility pipe penetrations maintaining a minimum clearance of six inches from the footing top and bottom. The trench excavation includes tamped sand bedding directly surrounding the pipe and compacted backfill above, with a minimum one foot six inch trench width. A two inch clearance is maintained between sleeves and pipes typically. Excavation limits restrict digging below the specified line adjacent to the structural wall and footing.
