Digital transformation can improve productivity and reduce uncertainty in AEC projects. BIM-based workflows play an important role in this transformation. The IFC format has emerged as exchange standard in road projects and allows BIM to be exported from design software to cost estimation software. Therefore, we tested a workflow in a real-life road project from Norway. We show how BIM-based cost estimation can be made with commercial software and uncover related challenges. We used a Design Science Research approach and developed an artefact in the form of an IFC based link between design and cost estimation software. IFC entities were expanded with coded properties based on standard specification texts. We concluded that BIM-based cost estimation improves productivity, reduces uncertainty and eliminates random human errors by automating repetitive and time-consuming tasks. Further research with different software and specification systems in more countries are necessary.
