Abstract:
Building codes and standards are the rules and guidelines that specify the minimum acceptable level of safety for buildings. MvdXML Checker is a building code checker for the automatic verification of IFC models and to detect the non-conformities with the associated 3D visualization. The verification approach is based on MvdXML rules to be used within the MvdXML Checker or IfcDoc tool developed by the buildingSMART International to improve the consistent and computer-interpretable definition of Model View Definitions. In this paper, we propose many extensions in the MvdXML Checker which are very useful for the verification of IFC models and discuss its implement as a web service. After these extensions, still we analyze that this traditional approach of verification by the use of MvdXML is very limited and has narrow scope for the verification of IFC models. Major limitations are identified such as restricted scope of applying conditions and constraints on several branches of an IFC model, poor geometric analysis of an IFC model, lack of mathematical calculations, support of only static verification of a model, etc. Therefore, finally we present a need of an approach based on Semantic Web technologies that can easily be extended, configured and deployed for the dynamic and changing environment having broad spectrum of functionalities for the Verification of IFC models.
