The rapid evolution of digital twin (DT) technology has opened new pathways for transforming the management and resilience of civil infrastructure systems. A digital twin, functioning as a dynamic and continuously updated digital replica of physical assets, facilitates real-time monitoring, predictive maintenance, and data-driven decision-making. Within the context of smart infrastructure, DTs enable improved allocation of resources, reduction of operational risks, and enhancement of disaster preparedness and recovery strategies. This paper investigates the integration of DT technology into smart civil infrastructure with a particular emphasis on emergency response and resilience. We outline a structured methodology for implementing DT frameworks, including data acquisition, real-time synchronization, and intelligent analytics. Furthermore, we critically evaluate related work to highlight existing advancements and identify research gaps. The discussion underscores the role of DTs in strengthening situational awareness, optimizing response strategies, and ensuring long-term sustainability of critical infrastructure systems, ultimately contributing to safer and more adaptive urban environments.
