A cast-in floor box opening forms within a concrete slab-on-grade over a compacted sub-base. The recess includes a drop-down concrete trench reinforced with continuous number 5 rebars at mid-height and standard 90-degree hooks terminating at the corners. Slab and wall reinforcement matches the surrounding slab-on-grade specifications, with access floor tiles installed as required per architectural drawings. Dimensions establish a maximum 1-foot-0-inch depth for the box alongside matching slab thickness requirements and 6-inch side clearances.
