Abstract

Precast construction has great potential for driving innovations in clean, safe, high-efficient construction methods in the industry. However, current precast supply chain management often faces challenges such as fragmentation, poor traceability, and lack of real-time information. To address these challenges, this study builds a novel blockchain-based information management framework for a precast supply chain, which extends the applications of blockchain in the domain of construction supply chains. In this study, a blockchain framework and its development processes are presented in detail, and algorithms for smart contracts are developed for the model implementation. Finally, the performance of this framework is validated with a case study in which a visualization system is presented to achieve (1) information sharing management, (2) real-time control of scheduling, and (3) information traceability. The results suggest that the proposed framework facilitates the on-time delivery of precast components (PCs) and tracks the reasons for disputes centered on PCs in the precast supply chain.
