Abstract

Highlights: We analyzed the FM activities and identified the BIM-based FM system usability. We suggested BPD considering variability related to BIM-based FM system development. We developed the pilot system of BIM-based FM with BPD about the FM case study. We proved BPD efficiency by conducting the statistics analysis. Abstract: The purpose of this research is to suggest and develop a building information modeling (BIM) database based on BIM perspective definition metadata for connecting external facility management (FM) and BIM data, which considers variability and expandability from the user's perspective. The BIM-based FM system must be able to support different use cases per user role and effectively extract information required by the use cases from various heterogeneous data sources. If the FM system's user perspective becomes structurally fixed when developing the system, the lack of expandability can cause problems for maintenance and reusability. BIM perspective definition (BPD) metadata helps increase expandability and system reusability because it supports system variability, which allows adding or changing the user perspective even after the system has been developed. The information to be dealt with differs according to the user's role, which also means that the data model, data conversion rules, and expression methods change per perspective. The perspective should be able to extract only the user-requested data from the heterogeneous system's data source and format it in the style demanded by the user. In order to solve such issues, we analyzed the practice of FM and the benefits of using BIM-based FM, and we proposed a BPD that supports data extraction and conversion and created a prototype.
