Integration of Parametric Product Catalogue Requirements in IFC

Abstract: An international, standardised product catalogue format representing parametric and variable product data, simplifying their exchange and integration, is to be developed. We map product data requirements in IFC files by leveraging lessons from existing national standards to enhance their parametric modelling capabilities. Using a case study, we evaluate the implementation of property value dependencies and valid combinations using a product catalogue example. Significant is the extension of data linking and value calculation in IFC, which integrates control structures. Of the three proposed implementation approaches, we favour the code-based solution to support the integration of parametrics in IFC for different applications.
