The construction industry is a significant contributor to global carbon emissions, with the production of concrete alone accounting for approximately 8% of worldwide CO2 emissions. To mitigate the environmental impact of cement, pneumatic void forms with individualized geometry are introduced to displace concrete in slabs where it is structurally unnecessary. These void forms have the potential to reduce cement usage by up to 35%. This paper presents the development of an adaptive Building Information Modeling (BIM) catalog to manage geometric and semantic data for numerous individually shaped pneumatic void forms for lightweight foundation construction. Utilizing open-source visual programming tool Dynamo, an adaptive BIM catalog script (ABC-Script) was developed to create individual void forms derived from four base forms and to enrich use-case-specific semantic information. Geometric and alphanumeric data are sourced from an external database. Through integration with Revit, the ABC-Script ensures precise placement and intersection of void forms within the foundation slab, facilitating efficient evaluation of different form variations and topologies. The resulting model can be exported as an Industry Foundation Class (IFC) model, adhering to the Open BIM approach for data consistency, supporting further use cases in planning and execution.
