What is the Built, or "Human-Made" Environment?

The built environment touches every aspect of our lives every single day. It encompasses the buildings we live and work in, the schools and hospitals we rely on for essential services, and the transmission and distribution systems that allow us instant access to reliable electricity, clean water, and always-on internet connections. 

The built environment also applies to the roads, bridges, rail networks, airports, and related transportation systems that guarantee our mobility and allow our economy to thrive.

As engineers, our member firms design the built environment. By extension, they create the physical spaces that allow society to thrive, create new opportunities, and break down historical barriers that hamper economic and societal equities.

Who are our member firms?

ACEC’s member firms represent the full scope of America’s engineering industry, from large national and international businesses to small local disadvantaged business enterprises. Our members work in all sectors of the economy, designing bridges and transportation networks for public clients, as well as datacenters, housing, and other private sector projects. 

Regardless of size, each of our member firms is connected by a common thread: they are all dedicated to make the world a better place for everyone

Our member firms are working every day to make our world a cleaner, more resilient, and sustainable place to live, work, and raise a family. They are designing the structures and systems that deliver clean air, clean water, reliable electricity, as well as the transportation systems to keep our economy growing.
