Building Information Modeling (BIM) plays a pivotal role in the construction management of dam engineering projects, which face challenges in data interoperability due to the absence of standardized data formats. While Industry Foundation Classes (IFC) offer a standardized digital representation of the built environment, it lacks the capability to accurately model the semantics of roller-compacted concrete dams. Therefore, this paper presents an extended IFC-based information exchange for the construction management of roller-compacted concrete dams, incorporating the development and validation of a prototype through a case study. The results indicate a significant enhancement in standardized information exchange for construction management compared to traditional practices. The approach facilitates BIM-assisted information exchange automation among stakeholders involved in roller-compacted concrete dam construction projects. The findings of this study provide valuable insights into dam construction management system prototyping and cross-platform collaboration.
