High-Speed Serverless IFC Data Extraction using C++ Compiled WebAssembly
Extracting spatial hierarchy, material quantities, and custom Property Sets (Psets) from IFC models inside headless AWS Lambda and Vercel functions.
Parsing raw EXPRESS-based STEP files on serverless platforms often hits memory and runtime constraints. Utilizing lightweight C++ WASM binaries allows serverless handlers to extract BIM metadata in milliseconds without launching heavy desktop software.
1. Geometry-Skipping Express File Parsing
Bypassing heavy 3D mesh tessellation loops during serverless execution lets extraction routines target pure semantic data (IfcBuildingElement, IfcPropertySet), drastically reducing function execution time.
2. Streaming JSON Property Tree Export
Converting nested IFC relational trees into flat indexed JSON stores allows immediate indexing into search engines and relational databases like PostgreSQL.
3. Automated Quantity Takeoff (QTO) Pipelines
Automating structural volume, surface area, and length extractions from IFC metadata streams enables real-time cost estimation microservices triggered by simple file uploads.
