Research of building evacuation path to guide based on BIM

As building structure is more and more complex, confronting evacuation prone to retrograde and blockage phenomenon, traditional plain of evacuation schematic has been difficult to meet the demand guidance for fire evacuation. In this paper, we propose a building information model (BIM) for the guidance of the three-dimensional building within the evacuation path. Full integration of BIM Technology and virtual reality technology, timely updates to the daily information, form a management platform, through this platform, so that the fire evacuation path is more intuitive, evacuation drills more convenient and management personnel to direct the rescue more accurately. Article schematic through normal fire evacuation, evacuation typical fire scenarios indicate two aspects to exhibit a three-dimensional analysis of the command to evacuate the building evacuation path.
