Twenty-five years ago, AECOM was formed when a handful of Ashland Inc. employees shared a dream of creating an industry-leading firm dedicated to making the world a better place.

On April 6, 1990, AECOM became an independent company formed by the merger of five Ashland entities. While our official founding was in 1990, some of our predecessor firms had distinguished histories dating back more than 110 years.

Since then, more than 50 companies have joined AECOM and, in 2007, we became a publicly traded company on the New York Stock Exchange (NYSE: ACM).

During 2014, our combination with URS Corporation was a game changer for the industry, more than doubling our revenue and workforce, furthering our status as the world’s #1-ranked engineering design firm by revenue, according to Engineering News-Record magazine.

In 2015, we were recognized by Fortune magazine for the first time as a World’s Most Admired Company.

Today, listed on the Fortune 500 as one of America’s largest companies, AECOM’s talented employees — including architects, engineers, designers, planners, scientists and management professionals — now serve clients in more than 150 countries around the world.

We are a premier, fully integrated professional and technical services firm positioned to design, build, finance and operate infrastructure assets around the world for public- and private-sector clients. We are a leader in all of the key markets that we serve — including transportation, facilities, environmental, energy, oil and gas, water, high-rise buildings and government — and provide a blend of global reach, local knowledge, innovation and technical excellence in delivering customized and creative solutions that meet the needs of our clients’ projects.
