About this detail

A 1-foot-8-inch square concrete pedestal is centered on a pad footing and anchored with eight #7 dowels spaced equally in a square pattern. The concrete pedestal features #4 ties at 8 inches on center, transitioning to three #4 ties spaced at 2 inches on center near the top. An optional construction joint is indicated with a roughened 1/4-inch amplitude surface. The adjacent elevator pit section details an 8-inch concrete wall reinforced with #5 bars at 12 inches on center each way, featuring 90-degree standard hooks and a 24-inch bend at the top slab connection. A door guide angle is specified per the manufacturer, with temporary shoring required until the slab above has fully cured.
