Topological integration of BIM and geospatial water utility networks across the building envelope

Utility networks comprise a fundamental part of our complex urban systems and the integration digital representations these across multiple spatial scales can be used to help address priority challenges. Deteriorating water utility infrastructure low routing redundancy result in network fragility thus supply outages when assets fail. Water distribution configurations optimised for higher resilience but simulations analyses are not integrated with finer scale inside buildings. This is hindered by differences conceptualisation semantics employed relevant data standards. We suggest that geospatial geometric contained Building Information Modelling (BIM) (WDN) models their integration; this supports use cases optimising dynamic partitioning, reducing risk underground strikes planning future topological redundancy. In study, we develop demonstrate application weight-based algorithm inferring connections between urban-scale WDNs BIM models, showing absence complete or consistent semantic representations. method has potential transferability other resources (such as waste water, electricity gas) make recommendations such standardising representation connection points disjoint extending normal practical remit MEP modelling encompass space buildings WDNs.
