A digital twin for AEC is a dynamic, up-to-date replica of a physical asset or set of assets— whether it’s a building, a campus, a city, or a railway—that brings together design, construction, and operational data. 

More than just a collection of 3D models starting from the design phase of a project, digital twin is dynamic. It incorporates sensors, Internet of Things (IoT) technologies, and artificial intelligence (AI), feeding real-time data back into the digital models. It evolves with input and gives asset managers new insights.
