A concrete elevator pit wall bears on a concrete footing with number 5 reinforcing bars at twelve inches on center each way top and bottom, featuring a roughened construction joint surface. A structural steel angle measuring 4x3x1/4 with half-inch diameter by six-inch heavy stud anchors at sixteen inches on center is embedded at the top wall corner as needed for elevator sill attachment. The concrete slab-on-grade ties into the wall with number 4 bars at sixteen inches on center, and vertical wall reinforcing dowels match the reinforcement from the wall above. The concrete footing requires a three-inch minimum cover over all embedded reinforcing steel.
