Advancing infrastructure BIM through integrated spatial data and enhanced data extractionTetteh, Manasseh (Avtor) Tekavec, Jernej (Mentor) master thesisspatial datadata extractionBuildings are spatial components that exist in a spatial context. Creating the geographical context for designers facilitates design analysis and municipal code compliance checks. Integrating BIM and GIS is beneficial for a wide range of spatial analysis and design validation. There are three main BIM and GIS integration approaches, which are BIM to GIS, GIS - BIM, and both GIS and BIM integrated in a separate tool or platform. This research focused on the second approach, which is GIS - BIM. Since both BIM and GIS are created for different domains and differ in their representation of data, the IFC schema was considered as the file exchange format for such integration. This is not new; however, most integration attempts using this approach have focused primarily on geometry with less consideration for semantics. A case study of a site divided into three zones with distinct geotechnical attributes was used for this research. After the transformation to IFC, the resultant model was linked into a Revit project to test its responsiveness when queried for design validation. This research demonstrates the flexibility of IFC for BIM and GIS integration. Additionally, semantics of the transformed GIS IFC data were established during the transformation. The topographical object, its property sets, and the hierarchical relationships were all modelled in the Feature Manipulation Engine (FME). However, the resultant GIS IFC model is not fit for use cases such as spatial boundary analysis or querying data within certain spatial constraints in native BIM environments. This research examines the possibility GIS - BIM models for analysis in native BIM environments.[M.
