Blockchain in construction supply chain management

This chapter focuses on applying blockchain technology to enhance construction supply chain management (CSCM). The chapter first identifies challenges within current CSCM approaches, including fragmented information sharing, lack of trust among stakeholders and the absence of a single source of truth. To address these issues, the chapter presents a blockchain-based CSCM system implemented in a real-world case study involving modular construction between Hong Kong and Mainland China. This pilot project demonstrates how blockchain improves supply chain transparency, ensures data immutability and facilitates efficient quality control processes. Additionally, the chapter provides practical guidelines for implementing blockchain systems, emphasising key considerations like stakeholder management, scalability and legal compliance. While the chapter underscores blockchain's transformative potential in CSCM, it also highlights unresolved challenges such as scalability limitations, regulatory uncertainty and resistance to change. It concludes by discussing future opportunities, including integrating blockchain with IoT, AI and DAOs, to further enhance supply chain resilience and efficiency.
