Six switchback flights wrapping tightly around a central HSS column — each landing at a different elevation with platform extensions branching off to adjacent floor framing. Every flight-to-landing connection had to account for the turning geometry while keeping stringer depths, tread spacing, and handrail heights code-compliant. Intermediate landing platforms with guardrail panels cantilevered off the central column required precise load path detailing.
Complete Tekla model of all six flights, landings, and platform extensions as one coordinated assembly around the central column. Every stringer, tread, landing frame, and railing post modeled with exact elevation and clearance dimensions for direct fabrication. Delivered with individual assembly drawings, railing panel details, and a 3D rendered package for client approval.
