As modular construction becomes popular, an increasing number of products are prefabricated in an offsite construction environment. While improving the productivity and efficiency of construction-oriented production, it also raises the complexity of process planning. Although the specifications of a product are fully defined by Building Information Models (BIM), no information is provided on how construction products are manufactured and assembled. This paper proposes an ontology-based approach aimed to link construction-oriented product assemblies and manufacturing resources using manufacturing operations. By identifying intersections of connecting members of a product assembly, feasible manufacturing methods and resources are determined based on expert knowledge and machine configurations. The proposed approach is validated using a wood frame assembly.
