Abstract
Web 3.0 has a significant positive impact on the development of cities towards becoming smarter, more resilient, sustainable, and net-zero-compliant. By integrating a mature technology using IoT, 5G or 6G, blockchain, spatial computing, VR, AR, XR, edge AI, and edge computing, as well as implementing digital twin technology concepts continuous improvement and predictive capabilities represent ambitious goals to improve infrastructure and services, benefiting both residents and the environment. A responsibly applied Web 3.0 and digital twin technology play a success-critical role in construction, infrastructure, and utility networks and significantly improves collaboration and increases efficiency and productivity. Combining the benefits with the latest advances in material sciences and nanotechnology, it may revolutionize construction and urban infrastructure design by improving efficiency, sustainability, safety, and collaboration. All these technologies provide tools for efficient decision-making for stakeholders and for optimizing the performance of their systems to achieve better outcomes for everyone involved. This section discusses key technologies and concepts for achieving a comprehensive understanding of the scope of this research.
