Digital Twin Construction & City

Aims & Scope

Digital twin (DT) is an integrated multi-physics, multi-scale, probabilistic simulation of an object or an activity, which mirrors the life of its corresponding physical twin. For smart cities and construction, DT can reflect both the semantic and geometric properties and behaviors through virtual models and data to achieve real-time sensing, dynamic control, and information sharing services. A set of innovative information technologies are adopted for the real-time data collection and decision making to develop construction DTs, such as Internet of Things (IoT), blockchain, computer vision, and cloud computing. Real-time data from DTs are shared in cloud space with cyber-physical visibility and traceability to facilitate design, construction, maintenance, and management of smart building and city. Multi-dimensional information including status, location, quality, cost, and safety could be revealed in high-fidelity DTs for stakeholders to monitor the construction progress on a real-time basis. Workers can also safely complete the daily tasks through dynamic control with enhanced information accuracy, timeliness, visibility, and handling efficiency. To make the latest research presented at the 5nd Digital Twin International Conference 2025 (DTIC 2025) widely available, DTIC is extending a Call for Papers for a Special Section reflecting the scope of the conference.
