About this detail

This concrete stair on grade detail consists of a solid concrete staircase supported by a 10-inch wide concrete footing with two continuous number four reinforcing bars. The stair treads and risers incorporate concrete fill with typical slab reinforcement consisting of number four bars at 12 inches on center continuously. A slab underlayment is placed beneath the assembly per plan and the geotechnical report, maintaining a three-inch clear cover at the footing bottom. The finish grade, nosing, tread detailing, and top of concrete elevations are coordinated per the architectural drawings.
