Record the service type, intended users, peak arrival interval, supervision model, entry and recovery task, operating hours, cleaning closures, staff route and any local public-use or accessibility review. A private coached appointment and an unsupervised hospitality amenity can require different circulation and recovery space around the same product.<\/p>\n<p>Use operating evidence where it exists. Timestamp arrivals, count waiting and recovering users, observe staff positions and record when a wet route conflicts with doors, benches or service panels. For a new facility, label every input as approved design value, qualified estimate, supplier value or open.
