A structural steel catwalk assembly is supported by an HSS10x10x3/8 post and HSS beams sized per plan, topped with steel grating. The support structure integrates double angle bracing of 2L5x3x5/16 long legs back to back, connected to the HSS post and structural framing. The assembly spans from a wide-flange beam and metal deck roof below up to the top of the catwalk elevation, with an adjacent curtain wall and screen wall framing elements. Various connection details are referenced to sheet S6.11 for specific node configurations and member intersections.
