Comprehensive and effective safety risk identification in metro construction has a significant impact on risk management. Although previous studies attempted to obtain a final ranking of the risk factors using various risk identification methods, they did not consider real-time risk identification. To address the complex issues involved, a model was established to identify the possible safety risks among the many potential risk factors in real time, considering the uncertain and complex environment in metro construction adjacent to buildings/structures. The study made decisions regarding the weights of the safety risk criteria at various stages of the construction. The safety risk factors and degrees of closeness were ranked at a specific time using real-time construction data. The model was demonstrated by real-time safety risk identification in a typical case study of metro construction adjacent to buildings/structures. The results are consistent with the reality of safety risks at various stages of such a metro project. The method of real-time risk identification is established to be feasible and effective, and experiments are proposed to identify risks in similar metro projects.
