New Database System Could Unlock Billions in Concrete Building Materials
Researchers have created a standardized framework for cataloging and reusing precast concrete salvaged from demolished buildings, potentially transforming construction waste into a marketable resource. The system addresses a critical barrier: buildings being torn down today contain usable elements, but architects and engineers lack reliable data to specify them in new projects.
Originaltitel: Guidelines for a database of reclaimed precast concrete elements
<p>The ReCreate project explores the possibilities of deconstructing and reusing precast concrete elements from end-of-life buildings that were not originally designed for disassembly. This report outlines a database for capturing, modelling, and exchanging data about reclaimed precast concrete. It focuses on database structuring, element verification, and the generation of standardised digital outputs for practical reuse in architecture and engineering.</p><p>Reusing precast concrete at scale requires that elements become available with sufficient documentation to architects and engineers. This report proposes a practical approach to achieving this by combining archival work, field documentation, and digital modelling into a coherent pipeline that produces an operational database structure. A prototype database demonstrated how each reclaimed element is documented as digital records linked to its donor building, including provenance, condition, material properties, and geometry, all expressed in a consistent format. The proposed workflow defines what is minimally needed to take an element from deconstruction to design, including naming conventions, traceable identifiers and interoperable exchange models.</p><p>Early implementations of the database on ReCreate’s pilots suggest that heterogeneous stocks of elements can be organised and reintroduced into design with modest friction, provided that uncertainties (such as missing values or approximate measurements) are explicitly flagged and data exchange protocols are observed. The report outlines limitations, such as incomplete drawings and manual metadata curation, and proposes pragmatic extensions to the current methodology, including batch exports, API access, and closer ties to digital twins and material passports. The approach appears transferable to other contexts and provides a foundation for procurement and stock estimation based on real, reusable components. The database is complemented by an IFC workflow allowing elements to be exported into common project environments and BIM platforms.</p>
