Digital Twins and Blockchain technologies for building lifecycle management

This paper reviews the potential applications of Digital Twins (DT) and Blockchain (BC) technologies throughout the building lifecycle phases by conducting a double-stranded systematic review of papers on the possible use of DT and BC. The results revealed the increasing interest in DT and BC and their potential use in all building lifecycle phases; however, studies focused mainly on the construction phase. The findings also revealed unique features of DT and BC, potentially supporting the proposal for their collaborative implementation to enhance building lifecycle management. This review's findings positioned the argument for more research on integrating DT and BC to augment building lifecycle management and the need to explore their relevance or role when transitioning from construction to post-construction. This paper elucidates readers on the potential role of DT and BC while developing a built asset and suggests directions for future research.
