AI BIM Clash Detection: Generative Auto-Reroute Simulator

Before a single beam is poured, coordination software scans a Building Information Model for places where structure, HVAC, plumbing and electrical systems occupy the same space. This simulator renders a real 3D structural bay — nine columns, a beam grid, an HVAC duct run and a plumbing pipe run — and applies the same axis-aligned bounding-box (AABB) clash-detection algorithm real BIM tools use, live, as you drag the duct and pipe through the structural grid. A clearance-tolerance slider turns near-misses into flagged violations, live readouts report the exact clash count and worst penetration, and an AI Auto-Resolve button runs a small generative search over candidate routing heights to find a clash-free layout — a miniature version of the constraint search real generative-design plugins run across thousands of routing options.
