Extending the current model view definition standards to support multi-storey modular building projects

Building Information Modelling (BIM) has significantly facilitated information management and collaboration in construction projects. During the past two decades, many information standards such as Information Delivery Manuals and Model View Definitions (MVDs) have been developed to enhance interoperability among construction-related tools. The focus of these standards has mainly been on conventional construction. In this paper, differences in the data structure of these two types of construction-related tools are discussed and compared with the current MVD standards. This study shows that the existing standards cannot fully support multi-storey modular buildings. By development of a product architecture model and comparing it with the data structure of current MVDs, it is concluded that available standards can be modified to support both modular and site-built constructions. In this paper, essential MVD concepts required for such extensions are presented. Through a case study, the developed concepts are applied to the currently available architectural-to-structural MVDs in order to create architectural to structural design/analysis MVDs for application to multi-storey modular buildings. The case study shows that using the presented concepts, an existing MVD can be extended to address special needs of multi-storey modular building projects as well as conventional construction
