These structural details outline the requirements for pipes passing through or just below spread footings, strip footings, and grade beams. Sleeves must be positioned within the center one-third of the footing depth, maintaining a minimum spacing equal to three times the maximum sleeve diameter. Double stirrups are detailed on each side of sleeves in strip footings with side bars bent around the penetrations. Additional provisions cover controlled low-strength material fill, minimum clearances, and maximum penetration limits based on footing geometry.
