A reinforced concrete ramp slab sits atop a twenty-four-inch diameter concrete column supported by an F1 concrete footing. The ramp slab features top and bottom longitudinal reinforcing bars, transverse bars spaced at twenty-four inches on center, and continuous fifteen-millimeter bars along the edges. The concrete column contains eight twenty-five-millimeter vertical reinforcing bars and fifteen-millimeter ties spaced at six inches on center. The twenty-millimeter transverse reinforcing bars extend into the footing and are sized per plan. Guardrails and landing details are coordinated with the architectural drawings.
