A concrete floor slab on metal deck bears on a steel beam protected with spray-applied fire safing. The exterior edge integrates a two-hour fire stop assembly supported by a clip anchored to the slab edge. A liquid-applied air and moisture barrier covers the exterior gypsum sheathing behind the exterior finish. Five-eighths-inch gypsum sheathing lines the interior side of the exterior wall assembly.
