A pipe penetration through a concrete wall footing with specified clearances and sleeve dimensions. A metal sleeve with a diameter equal to the pipe diameter plus two inches is installed through the concrete, featuring a collar around the pipe to prevent dirt intrusion. The design mandates a minimum three and a half inch clearance between adjacent pipe sleeves and limits the maximum penetration depth to three feet. Step footings are applied as required per typical details, with the general contractor coordinating exact depths and locations.
