Abstract：Introducing BIM into building operation and maintenance management (O&M management)
has significant benefits. Though the number of related literatures keeps increasing in recent years, current
domestic and foreign researches and applications on BIM-based O&M are generally in the exploratory
stage. Based on a broad literature survey, this paper reviewed domestic and foreign BIM-based O&M
researches and applications from the perspective of technology researches and application projects.
Relevant key technologies, research status and related system developments were introduced. The
functions and project applications were then summarized. Finally the challenges and bottlenecks for
BIM-based O&M management, as well as an outlook for future researches were discussed.
