Linking BrIM to BMS for bridges – concepts

Abstract

Bridge Information Model (BrIM) is currently replacing drawings as main deliverable in new bridge project. Several use cases for BrIM over its lifetime is identified, as well as a discussion of the use case potential. Use cases include, but are not limited to, linking Bridge Management Systems (BMS) and BrIM, handling inspection data, visualizing inspection results and damage, tracking maintenance actions and structural changes. It may also serve for the analysis of residual strength, as digital twin in structural health monitoring (conditional maintenance) and as risk-based decision-making tool for the allocation of resources. Thus, this paper will form a basis for updates of relevant IFC classes in the BrIM data structure to facilitate seamless communication between BrIM and BMS systems. Thereby the grossly different level of detail in BrIM (individual objects), GIS (road network) and BMS (asset portfolio), the data aggregation and drill-down, and the portability of existing data collections are major concerns.
