Cities have become early adopters of digital twin technology, and, as such, city planners are using virtual models to gain a competitive edge. Digital twins are disrupting the way capital projects and infrastructure are planned, built, and operated. The technology’s enhanced predictability and performance capabilities attribute to this disruption. The most significant use case of this innovative technology is capital projects during the development and operation of cities. Here, city planners, architects, constructors, operators, and even road and utility authorities can maximize the potential of the technology. As more global cities, including the world’s largest cities, begin adopting digital twins, the industry must examine how they impact large-scale projects and how this impact will develop in the future.
