The scupper casting is secured to the wall face using expansion anchors as required by the manufacturer. The outlet centerline is positioned one foot above adjacent grade, with piping extending back through the wall to the roof drain. Structural details for the tilt-up wall and slab are coordinated per structural drawings.
