The cast-in-place concrete treads and risers are supported by concrete fill over metal deck, which rests on wide flange steel interior framing sized per structural drawings. A hot fluid-applied rubberized asphalt waterproofing membrane is applied beneath the concrete fill. The cast-in-place concrete landing extends at the base, bordered by a standing seam metal panel pony wall. A high performance coated steel handrail with an integrated light fixture is mounted along the stair.
