This weekly infrastructure and city planning update reveals emerging applications of smart technology and intelligent systems in urban development. The most direct example of AI-powered innovation involves digital twins—virtual models of physical infrastructure—being deployed to transform urban infrastructure management and improve efficiency. In Portugal, the city of Porto launched an intelligent citizen engagement app called WAKE UP that uses data analytics and smart algorithms to help residents reduce their carbon footprint. The app tracks water usage, electricity consumption, transportation choices, and waste sorting, then converts these actions into carbon points. Meanwhile, the smart city research community continues advancing climate-resilient urban solutions with intelligent approaches to flood management and green infrastructure. The housing and sustainable development sector held a major conference in Saudi Arabia to discuss future urban planning strategies. While true AI agents specifically managing infrastructure remain limited in these reports, cities worldwide are increasingly adopting intelligent data systems for better planning and sustainability.
