The circular building concept entails the ability for building components and materials to be kept in a closed use-cycle; however, due to the complexity of buildings, a significant factor that can ensure its circularity is its detachability. Building detachability is the extent to which building components can be deconstructed without damage, and this master thesis targets the optimization of its assessment process using BIM. To achieve this, the detachability assessment processes from currently available building circularity assessment methodologies and their integration with BIM were analysed. Followed by the research into a workflow for automating the evaluation of building detachability using BIM. The adopted workflow for this thesis entails representing the detachability assessment process using business process models and notations (BPMN), deriving the model information requirements for the assessment through the creation of attribute matrices and developing a dynamo script to conduct the assessment process. It was discovered that effectively interpreting the conventional building detachability assessment requirements will result in better BIM integration and automation. However, there is a need for better standardization of the conventional assessment requirements. Likewise, by using projects’ employer’s information requirements (EIR) and BIM execution plan (BEP), the adopted workflow can be integrated into BIM-based projects.     «
