Employing the BIM approach during the operational phase of an infrastructure asset’s life cycle represents the largest opportunity for reducing the total life cycle cost. One aspect of the operation of an infrastructure asset is to monitor its structural performance to ensure safety, for which structural sensors are increasingly being used. Semantically rich as-built BIM models that represent the actual conditions of the constructed assets can improve and quicken the structural performance monitoring of infrastructure assets. Nevertheless, the current open data model standards are not fit for this purpose yet, which greatly reduces the usefulness of the BIM approach during the operational phase of an infrastructure asset. This paper examines the capabilities of existing data model standards and, based on alternative approaches to overcome the lack of current capabilities and a proposed use-case, makes recommendations for possible extensions to the standards. The paper concludes that amendments to current data model standards are needed to enable modelling of complex monitoring systems and appropriate management and visualisation of sensor data.
