Five coordination agents, one federated floor model. Each calls a spatial tool — clash, fit, clearance, line-of-sight, reachability — and gets the exact answer in milliseconds.

Top-down floor plan. Red box = duct/pipe clash · red dashed = chiller blocked at the narrow mech-room door · blue = a person's collision-free route · green/red = camera line of sight (clear, then blind spot behind the column) · dashed circle = 1.5 m turning clearance at the lobby point.
Clash-detectcollision (scene geometry)
"Do duct_A and pipe_B clash?"
↳ CLASH — duct_A and pipe_B intersect by 0.30×0.30×0.60 m (54 L of shared volume) — reroute one before fabrication

Constructabilitynavigation_plan
"Can the chiller be moved from the entrance to the mechanical room?"
↳ NO — the chiller (Ø1.0 m) cannot pass; the 1.2 m mechanical-room doorway is too narrow (no_path) — widen the opening or pre-place it

Accessibilityclearance (scene geometry)
"Is there 1.5 m turning clearance at the lobby point?"
↳ PASS — 2.35 m clear at the lobby point (nearest: part_b); code wants a 1.5 m turning circle

Securitycheck_visibility
"Does the camera cover the corridor end (line of sight)?"
↳ NO — the corridor end is in frame but occluded by column — a blind spot; reposition the camera

"Is the mechanical room reachable from the entrance at all?"
↳ reachable — 13.8 m collision-free route on foot from the entrance to the mechanical room (45 waypoints)

What this shows. One BIM floor fragment checked by five coordination agents against a single Universtato model: a 3D duct/pipe clash from scene geometry, chiller constructability and mechanical-room reachability via navigation_plan (the agent radius decides what physically fits through the 1.2 m doorway), ADA-style turning clearance from a floor point, and the security camera's true check_visibility line of sight — the column casts a real blind spot. The engine computes each answer exactly; it does not eyeball the drawing. Maps to research items #14 (clash detection), #15/#18 (constructability / coordination), #16/#40 (accessibility & clearance), #17 (camera coverage / LOS). Latency and determinism measured on this machine.
