A reinforced concrete column footing supports a vertical pilaster with a twenty-inch square cross-section. The pilaster features a blockout at its top for steel column installation, designed to be poured solid after the column is installed with two number five dowels featuring six-inch drill epoxy at each face. Reinforcement consists of eight number seven bars at non-frame columns with number four ties at six inches on center typical, while stair tower columns require four number five bars. The concrete footing dimensions are sized per plan and reference the footing schedule for structural requirements.
