CEA at the European Council on Computing in Construction Conference

Clara Blum, Vanessa Costanlonga, Kasimir Forth, Jens Hunhevicz and Zain Karsan presented their research at the European Conference on Computing in Construction and the 42nd International CIB W78 Conference on IT in Construction (EC3 & CIB W78 Conference), held in Porto, Portugal, on 14–17 July 2025. 

Doctoral candidate Clara Blum presented a paper comparing the performance of data carriers in realistic experiments to track circular construction supply chains. Findings indicate that, relative to DPM, RFID and NFC offer improved usability and reduced reading times with minimal differences in error rates. These results were strongly influenced by usability and experimental context. Clara also won the prestigious Thesis in 3 Award. 

Postdoctoral researcher Kasimir Forth presented a paper formalising information for disassembly potential of buildings using BIM and labeled property graphs. Tested in a case study, this approach was found to enhance assessments of disassembly potential, thereby providing designers with improved insights for early-stage circularity decisions. He also presented a second publication about material detection and classification in 2D architectural drawings that compares three different CNN models to investigate how computer vision can be used for material passports. Case studies validate the best-performing models’ practical effectiveness, especially for reinforced concrete elements, showing the potential of this computer vision-based method to aid digitalisation and resource-efficient retrofits.

Postdoctoral researcher Jens Hunhevicz presented a paper about a customised data environment for small and medium construction enterprises. Insights into both the tool and the process evolution will help other SMEs facing similar integration challenges.

Doctoral candidate Zain Karsan presented a paper about graph-based disassembly sequencing with structural and stability constraints of steel structures. The proposed algorithm can compute feasible disassembly sequences with sufficient speed to support applications in online robotic path planning. 

Their papers will be available open access via the external page ITC Digital Library of Construction Informatics at a later date.
