RFID-based traceability system for constructional steel reuse

This paper introduces a traceability system based on radio-frequency identification tags attached to the steel building components to provide a link to the cloud-based electronic material passport and 3D information model obtained by aerial scanning of the building before deconstruction. With such traceability system, the complete and accurate information about the building components, their quality and history can be readily available before the deconstruction of the building. This will allow more efficient reuse and better decision-making in deconstruction planning phase. For instance, it would be also possible to check actual demand for the particular component or the whole assembly. The technology was demonstrated on a real deconstruction and reuse of industrial steel hall in Tampere, Finland.
