Using BCF as a mediator for task management in building design

buildingSMART has adopted the BIM Collaboration Format (BCF) to improve interoperability in the field of process information exchange. The original scope of BCF was linked to a need to communicate BIM-related tasks, but a further expansion of the BCF format should be considered to add additional support to industry requirements for task management. The research described in this paper was based on literature studies of industry needs and evaluations of the current BCF specification and its implementation in software, and it identified some challenges in the current state of BCF. Based on these findings, we propose an information system consisting of decentralised model and task servers using both BCF and IFC. Using IDM Part 2 as an example, we further propose an architecture to expand BCF.
