About this detail

A concrete sump pit is recessed into the slab-on-grade with a depth of two feet and a width of one foot, featuring top and bottom reinforcing steel throughout the concrete walls and slab. A structural steel angle frame sized L3x2x3/16 with the long leg vertical is anchored around all four sides of the pit perimeter using three half-inch diameter by three-and-a-half-inch long anchors. Steel grating provided by the architectural package rests within the angle frame flush with the surrounding floor level. Additional reinforcement lap splices and concrete wall thicknesses are coordinated with the typical elevator and escalator pit details.
