Actor-based Framework for Interoperable BIM Data Management

This paper presents a novel framework designed to decentralise data management and enhance collaboration and interoperability in the Architecture, Engineering, and Construction (AEC) sector. By integrating BIM with a representation of building elements as independent actors in an actor-based system, it supports scalable and parallel workflows, allowing to concurrently access and modify distinct parts of the model. Semantic Web Technologies ensure that the data is linked and structured. The framework was tested in a controlled environment, demonstrating its ability to manage element-level actors, propagate changes asynchronously, and maintain data consistency. However, the complexity of maintaining decentralised components remains a challenge.
