Future research directions of construction digital twins

Abstract: The Digital Twin (DT) concept has emerged as one of the main topics within automation in construction. However, compared with the applications in other industries, several challenges must be overcome when generating Construction DTs (CDTs). In order to capture the leading edge of CDTs and identify the challenges of their implementation, this paper conducts a review of the previous studies related to DTs in the construction industry. Based on the review, the future research directions for the generation and applications of CDTs are identified.
