Development of Lightweight BIM Shape Format Structure to Represent Large Volume Geometry Objects Using GIS with Facility Management

This study focuses on the development of a lightweight building information management (BIM) shape format (LBSF) structure to represent largevolume BIM geometry objects using the geographical information system (GIS) with building facility management. Recently, BIM-based facility management with GIS has been researched with regard to urban facility management. To implement this use case, the BIM geometry objects are required to be effectively visualized on the urban level using GIS. Therefore, a lightweight BIM shape format is designed with these considerations, and the prototype for the pilot test is implemented. In the pilot test phase, after developing the Industry Foundation Classes (IFC) file and LBSF file for the model data of the three areas, performance comparison with regard to the data volume and screen loading time was made.
