About this detail

Proper installation requirements for utility pipes passing near or under concrete column footings and walls. Open or backfilled pipe trenches running parallel to footings must maintain a specific angular clearance line from the bottom edge of the footing bearing on undisturbed soil. When a pipe sleeve is required, it must provide a minimum four-inch clearance plus the outside diameter of the pipe, with three-thousand PSI concrete fill placed around the sleeve prior to pouring the footing. Footings must be stepped so as not to exceed three feet in depth, and no pipes are permitted to pass directly through the footing unless specifically noted otherwise. Column and footing centerlines must coincide unless indicated otherwise on drawings, with column dowels and reinforcement sized per the column footing schedule.
