, offering solutions to some of the biggest challenges in the architecture, engineering and construction (AEC) industry. As the demand for infrastructure rises, organizations are turning to AI to address skilled labor shortages, improve efficiency and promote sustainability.

The global infrastructure gap — estimated at $15 trillion — calls for smarter, more efficient approaches. AI is already helping bridge this gap by automating repetitive tasks, such as converting complex 3D models into manageable formats, freeing engineers to focus on more critical work. These AI-powered tools are reducing costs and improving resource efficiency in projects.

AI’s impact also extends to waste reduction and energy efficiency. Digital twins and machine learning models can detect off-spec materials and excessive energy use, allowing real-time adjustments that minimize waste and optimize sustainability. In an era where environmental concerns are at the forefront, AI is driving more responsible design and construction practices by cutting material waste and promoting greener designs.

Beyond that, AI is revolutionizing operations through . Digital twins powered by AI can optimize energy use and space management, making buildings more efficient and cost-effective to operate. AI’s ability to simulate various scenarios enhances renovation and retrofitting, allowing for faster, more cost-effective updates to existing infrastructure.

As AI technology evolves, its role in infrastructure development will continue to grow. By combining human expertise with AI-driven insights, the AEC industry is better equipped to build sustainable, resilient infrastructure that meets future demands.

In cities around the world, the concept is gaining traction as a model for accessible, sustainable and community-focused urban design. Based on an idea championed by Carlos Moreno, a professor at the Sorbonne University in Paris and special envoy for smart cities for the mayor of Paris, the goal of the 15-minute city is to create neighborhoods where all essential services are within a short walk or bike ride. By reducing dependency on cars, the model fosters healthier lifestyles, lowers emissions and creates vibrant, locally focused communities.

This vision isn’t just for Europe — U.S. cities are exploring ways to adapt the concept to American landscapes. Cleveland, Ohio, a city known for its automotive heritage, is one of the leaders.  Under , Cleveland has been to encourage denser, walkable neighborhoods where local businesses and public transit options take priority over sprawling developments. The initiative shows how even car-centric U.S. cities can pivot towards a people-focused approach, proving that this urban model can adapt to cities of all shapes, sizes and histories.

As support for walkable cities grows, , showing the impact of accessible urban design and fostering public awareness and engagement. While implementing the 15-minute city concept poses challenges, particularly for cities built around cars, the potential benefits — healthier communities, reduced pollution and a better quality of life — make it a transformative strategy for the future.

San Francisco is — a transit solution along Geary Boulevard and 19th Avenue that could turn a 75-year-old dream into reality. The plan envisions an underground line connecting the city’s west side to downtown, offering major relief for the nearly 50,000 daily riders who brave the 38 Geary and 38R Geary Rapid bus lines.

The subway would link key destinations like Stonestown Galleria, San Francisco State University and Daly City BART while providing much-needed connections to the East Bay and San Mateo County. The project is part of a broader effort, the ConnectSF initiative, which aims to reshape how people move through the city.

Community feedback has been enthusiastic, with many hoping the city can pick up pace. If approved, the subway could create 81,000 jobs, shave off 48% of transit time during rush hour and help address the city’s housing and transit needs. But, with an estimated $20 billion price tag, the project is far from pocket change. The (SFCTA) planners call it a “generational, transformative project” — a bold step toward making downtown traffic jams a thing of the past.
