Wood stringers and plywood sheathing form the stair treads and risers, supported by a concrete floor slab with stringer connections sized per structural drawings. Stair finishes are coordinated per the finish plan, featuring a contrasting two-inch wide visual strip at the nosing. Risers maintain a maximum height of seven inches while treads provide an eleven-inch minimum depth with a one-inch nosing projection. Skirt boards finish the wall-side edge of the stair assembly.
