3D indoor GIS is now being widely used as its improved spatial visualization can be applied to a variety of projects – one of which is emergency management in multi-level buildings. This study assesses the fire evacuation plan of the Main Library in the University of the Philippines – Diliman using 3D indoor GIS. Currently, the Main Library has a two-dimensional fire evacuation plan for every floor all following general routes to several exit points. With 3D indoor routing using GIS and network analysis, an origin-based and scenario-dependent evacuation management plan is created to have a more systematic process for fire events. Certain factors – priority of resources, origin of fire, all possible routes and exits, duration of evacuation – were used as basis of the fire evacuation plan assessment. The resulting geometric 3D model of Main Library is presented with both the library patron routes and staff routes that have stops along the way in to save priority resources before proceeding to exit points. Color-coded routes are mapped out symbolizing evacuation time while the route line thickness represents the population count in each route. Furthermore, three obstruction scenarios were created in order to simulate a fire event. Although a fire model was not considered, the scenarios proved to show the versatility of the generated routes in accordance to each case. Additionally, two new exit points were suggested for the ease of the library staff – who had a much longer evacuation time – resulting to an average time deficit of 15.25 seconds.
