Blockchain applications for construction contract management: A systematic literature review

Recently, there has been increasing interest in the research of blockchain applications in construction contract management (CCM). CCM is currently flawed, mainly lacking in information sharing, on-time payment processes, and an easily traceable supply chain. Applying blockchain-based applications can achieve autotransaction processes, create a secure information delivery environment, and promote collaboration among organizations. This research aims to discuss the application of blockchain technology in construction contract management, evaluate the benefits and drawbacks associated with blockchain application, and propose recommended strategies to facilitate the smooth implementation of blockchain technology for improved construction contract management practices. A systematic literature review is used as the main research, and content analysis is employed for analyzing the literature. The literature analysis shows that blockchain application in CCM mainly falls under three areas: information management; payment management; and supply chain management. Under each area, the current drawbacks in CCM, as well as the opportunities and challenges associated with blockchain applications, are presented. This research is one of the first attempts to examine the application of a blockchain in CCM systematically; it also provides construction contract managers or administrators with practical guidelines on leveraging blockchain technology to improve CCM practices.
