This week saw major developments in AI-driven infrastructure and city planning across the United States. Construction companies are using AI safety tools to protect workers, with Boston-based Shawmut reporting success using phone-connected AI systems to prevent accidents.

The U.S. government identified 16 federal sites for new AI data centers, aiming to build facilities that could use nuclear power and geothermal energy. This plan faces challenges as communities push back against AI infrastructure projects needing lots of land and resources.

Denver launched a program to create an AI vendor pool, making it easier for the city to buy smart computer systems for services like traffic control. Researchers also used AI to study zoning rules in 2,000+ U.S. communities, finding many now allow mixed-use neighborhoods that combine homes and shops.

Cities are turning to AI to fight climate change, with new systems tracking energy use in buildings to help meet net-zero goals. Experts warn that building AI infrastructure requires careful planning to balance tech needs with community concerns about water and electricity.
