Integrating Building Information Models with Authoritative Irish Geospatial Information

Building Information Modeling (BIM) is a key enabler to support integration of building data and is an important aspect to support a wide range of use cases, related to building navigation, control, sustainability, etc. Open BIM faces several challenges related to standardization, data interdependency, data access, and security. This means that there is often limited availability of BIM models. In Ireland, the Ordnance Survey Ireland (OSi) has a substantial dataset, called Prime2, which includes not only GIS data (polygon footprint, geodetic coordinate), but also additional building specific data (form and function). In this paper, an extension of an applied and tested methodology for uplifting GIS data into RDF is demonstrated for interlinking to a well-established BIM standard in the Architecture, Engineering and Constructionindustry called Industry Foundation Classes, using geolocation. This builds on initial work interlinking OSi building data with DBpedia. By interlinking building data in this way and making it available to query over, new insights and knowledge about buildings in Ireland can be made. This is an important step towards the iterative integration of ever more complex BIM models into the wider web of data to support the aforementioned use cases.
