From Inspection to Digital Passport: Tracing the Provenance of Testing Data of Concrete Components for Circular Reuse

Abstract: Circular reuse of construction components, prioritized by the EU over recycling, is limited by the lack of legally reliable, element-specific information in BIM environments. This work proposes a literature-based parameter set for the reuse of reinforced concrete elements as part of a product passport. Data from legally signed inspection certificates are integrated with digital BIM representations using established ontologies (BOT, Metadata4ing, ISOProps). Information is extracted from signed PDF certificates and linked to IFC models. Feasibility is demonstrated through a case study, enabling an interoperable, auditable workflow supporting End-of-Life-to-reuse information continuity for reinforced concrete elements.
