About this detail

Concrete footings and foundation walls accommodate mechanical piping through sleeved penetrations and stepped transitions. Pipes routing through or below footings require continuous footing reinforcement interruption with additional matching reinforcement placed around the penetration. Sleeves are provided around all pipes passing through walls and footings, maintaining specified clearances such as a one-inch minimum from reinforcement and a six-inch minimum clearance where dimensions dictate. Where footing steps exceed one foot six inches, typical footing step details apply with twenty-four bar diameters lap lengths.
