The application of traditional Gustav Purt fire assessment in urban village does not integrate the necessary information quickly and fails to represent the scope of visualization, and Geographic Information Systems (GIS) is also not well suited for complex buildings, e.g., urban village. To remedy these deficiencies above, this paper analyzes the feasibility of GIS+BIM technology for fire risk early warning management in urban village and verifies it by case studies from the perspective of risk early warning management method. The case study finds two pressure relief of the building complex, which played a positive role in the fire risk early warning management in the urban village. Compared with the traditional method, GIS+BIM technology is more scientific and reliable, which achieves cost reduction when applied to the Gustav Purt fire assessment in urban villages.
