Toward complete circular reuse: A database system for reclaimed precast concrete elements

Abstract

Drawing on years of structural reuse research and pilot deconstructions, this paper consolidates practice-based knowledge into a relational database spanning the value chain of precast concrete elements. A multi-layer framework maps provenance and raw metadata into a core schema, derives physical properties, and auto-computes design capacities, linking them to mainstream BIM workflows. Geometries are parametrically encoded as Cartesian WKT, steel reinforcement through zone- and layer-based reference systems, and material properties are integrated using aggregated historical libraries. Quality management, LCA, and LCC modules extend decision support. The framework is validated on 1878 reclaimed elements from five European pilot projects, and demonstrated through automated capacity checks and generative IFC modelling. A prototype Autodesk Revit add-in enables rapid placement, structural verification, and environmental appraisal. The proposed system provides a foundation for future automation in the emerging circular construction sector, enabling standardised product modelling with ETL and BIM interchange, advancing circular, data-driven construction.
