Abstract

Building handover is a critical stage in the building lifecycle, yet project information is often fragmented, difficult to verify, and hard to reuse in later operation and maintenance. Digital Twins (DTs) can improve lifecycle visibility, while BC can strengthen trust and traceability(Dounas et al., 2020). However, current studies rarely combine these with semantic knowledge representation. This work proposes a Blockchain-enabled semantic DT framework for building handover, using a five-layer architecture and a knowledge graph to structure building information. A lightweight prototype demonstrates trusted data admission and auditable event recording. The contribution is a practical and reproducible framework for improving lifecycle continuity beyond handover.
