Work performed and main achievements (WA1–WA6):
This section covers the updated status at M18 and summarises all technical and scientific activities and main achievements carried out during the first reporting period (M01–M18).
WA1 – Pre-requisites for smart data acquisition and interoperability in circular construction (WP1)
All tasks were completed. The work delivered the full set of definitions, classifications and standards needed for material identification, regulatory alignment and data interoperability. DMP, DPP and DBL structures were established, relevant standards mapped, and the economic and policy groundwork completed. GENIA, CIRDAX and CONCULAR were aligned through a first integration framework with API structure, data schemas and auxiliary data incorporation for pilots.
WA2 – Techniques & technologies for identification, analysis, digitalization (WP2, WP3)
All acquisition technologies were developed and deployed in the three pilots: AR-based RGB-iMMS scanning was completed with improved tagging and colourisation and first AI segmentation workflows. AHS produced calibrated datasets for timber. XRF generated a complete elemental library for concrete and asphalt. MFT delivered validated reconstructions and detection results. GPR-ECT characterised internal layers, reinforcement, defects and facilities. FOS systems were installed and calibrated, supported by FEM modelling and initial AI anomaly-detection architecture.
WA3 – Reduction in construction and demolition waste (WP4, WP5)
Material inventories and circularity assessments were completed for all case studies. The multisensory CDW characterisation system was fully developed and calibrated, producing a structured dataset of signals from controlled and real samples. Preparatory work for urban mining concepts and reusability assessments progressed in line with pilot data.
WA4 – Increased supply of secondary materials & improved facility to reuse/repair construction products (WP6, WP7)
The design of the C-BIM environment and DMP structures was finalised. Interoperability rules and prototype implementations for GENIA, CIRDAX and CONCULAR were produced. Economic and sustainability analyses were completed, synthesised in updated guidelines within the Circular Deconstruction Handbook and aligned with upcoming C-BIM integration steps.
WA5 – Improvements to labour productivity (WP8, WP9)
All analytical tasks were completed. Labour-productivity barriers, enablers and business models were identified through literature review, surveys and interviews across the three pilots. Technology-acceptance results and preliminary policy insights were produced. These results form the basis for the project’s circularity indicators and the next-phase evaluation models.
WA6 – Demonstrators in existing built works (WP10, WP11, WP12)
Baseline work for the three pilot sites was completed. All planned scans and measurements were carried out. Material samples were collected, mock-ups prepared and datasets consolidated. Technical alignment with data-platform and C-BIM development requirements progressed as expected, ensuring readiness for WP11 and WP12.
