Abstract: In order to determine whether there are deviations in the fire safety of buildings and whether supporting fire protection measures are in place, this study uses Revit software to establish a highly interactive BIM model. Through FRAME method, combined with potential fire risk factors, probability of fire occurrence, and degree of damage caused, a rapid and accurate fire risk situation assessment of buildings is carried out with the goal of "acceptable risk". Finally, an example of cold storage was used for validation.

Key words: building fire, BIM, fire risk, acceptable risk, fire risk assessment
