The framing layout consists of C8x11.5 channel members and MC12x10.6 channel stringers supporting the stair run and landing areas. L4x4x1/4 structural angles are spaced at two feet on center to support the walking surface grating. Detail callouts reference architectural coordination points across multiple sheet locations. The boundary dimensions coordinate with adjacent architectural elements.
