![]() It is generally accepted that BIM-related technologies offer considerable advantages to many, perhaps most, participants in the construction sector (Eastman et al., 2011). In the 2017 tests, improvements were observed though there were still significant processing failures that could result in serious errors particularly in the case of the BIM library components imported into project design models.Īs Building Information Modelling (BIM) becomes more prevalent in the construction industries of the world some of the practical problems of authoring and sharing models are also becoming more evident. In the 2012 study, 11 commonly used BIM tools showed a dramatic failure to process the geometries as intended, indicating that the authoring tools, whilst technically capable of supporting required component geometric representations, were constrained from doing so by their conversion interfaces with IFC geometries. A simple test model was created representing significant types of geometry encountered in component libraries, which were then expressed in IFC files. These assertions were tested, first in 2012 and then in 2017 to assess the state and evolution of interoperability in the industry. AbstractThe authors investigated issues of geometric interoperability for reusable BIM components across multiple platforms using industry foundation classes (IFCs) which many proprietary BIM software platforms claim to fully support. ![]()
