In this study, we propose software architecture for the effective integration of building information modeling
(BIM) into a geographic information system (GIS)-based facilities management (FM) system. This requires the
acquisition of data fromvarious sources followed by the transformation of these data into an appropriate format.
The integration and representation of heterogeneous data in a GIS are very important for use cases involving both
BIM and GIS data, such as in the management of municipal facilities. We propose a BIM/GIS-based information
Extract, Transform, and Load (BG-ETL) architecture that separates geometrical information from that related to
the relevant properties. The property required for each use-case perspective is extracted and transformed from
information for the BIM with FM to GIS using the ETL concept. In consideration of the viewpoint of geometry,
the surfacemodel for several representations in the GIS,we designed BG-ETL, developed a prototype, and verified
the results through interviews. The results show that BG-ETL considering BIM/GIS integration issue has benefits
such as reusability and extensibility.
