Abstract

A request for a route guide to a destination in a building is received from a user terminal device. BIM data for the building is received, including material properties of the building elements, the material properties consisting of ease of slipping when wet, earthquake resistance, and flame retardancy base values. Security information for a route, real-time information for building status, and a user profile are received. A route guide to the destination in the building is created, based the BIM data, security information, real-time building status, and the user profile. Information from one or more environmental sensors is received indicating that an environmental event has been detected. Its current position is received from the user terminal device. The route guide from the user terminal device's current position is updated based on the environmental event, and the material properties of the building elements that are related to the environmental event.
