Automized Planning & Data Exchange for Prefabricated Façade Renovation Processes

Abstract: Europe’s renovation rate remains below what is needed for climate-neutrality targets; scaling façade refurbishment demands standardised, data-driven automation. Current practice relies on bespoke BIM modelling and file-based scan-to-BIM pipelines, which are labour-intensive, sensitive to as-built deviations, and fragmented across design, production, and logistics. We present an end-to-end workflow that ingests 3D point-cloud surveys and performs geometric panelisation to derive storey-scale and small prefabricated façade panels. The system outputs IFC-compliant panel objects with cut-outs and metadata, synchronised via a self-hosted, versioned Speckle hub. A residential case study shows reduced manual modelling and reliable handover.
