Topological Negotiations: Parametric Mediation for Medical Circulatory Conflicts via Suspended Corridor in Historic Baise Baise People’s Hospital sits in Guangxi’s historic urban core. It comprises four buildings—Inpatient, Ward, Surgery, and Support—around a plaza. The space faces three demands: surgical transfer, emergency access, and parking for 1,000 motorcycles. At peak hours, these clash—stretchers meet vehicles, sirens fade into traffic. A suspended corridor was introduced. Ground level stays open for emergencies; the curved upper path halves transfer time from seven to three minutes. The corridor spans over an existing basement with irregular columns and dense pipelines, making coordination difficult. Using four parametric arcs as boundaries, the team linked structure, façade, and nodes to a dynamic model, allowing real-time adjustments to site deviations and minimizing rework. The corridor avoids cultural symbolism, focusing instead on a core challenge in hospital upgrades in China’s old urban areas: reconstructing medical flow under tight timelines and uncertain site conditions. It prioritizes patient safety and imposes order on complexity.
