Be a part of a bigger story. We're hiring.

Our California region — anchored by our primary office in Brea, which opened in 2010 — delivers engineering, environmental, construction and consulting services in combination with employee-owners in offices worldwide. As a 100 percent employee-owned firm, our focus is on superior service to exceed client expectations.

Our work in the region — combined with that of our Los Angeles, San Diego and San Francisco Bay Area offices — focuses on projects and services in the aviation, environmental, federal and power industries, and our professionals apply our broad corporate resources to meet client needs in any market. We leverage our design-build, owner’s engineer, program management and project controls experience to support success on projects of all sizes.

Our founding partners set out from Stanford University in 1898, building a firm from Kansas City, then branching back into California in the 1920s with waterworks, sewer, sewage disposal, electric lighting, and public utility appraisal services. Since that time, we’ve expanded to serve clients with wide-ranging services, including:

Business Diversity

We are committed to maintaining a diverse mix of suppliers, because they are key in providing innovative ideas to help our clients achieve success. By actively helping a wide variety of businesses belong to our project teams, we enrich those projects and our communities in ways that go beyond the tenets of law. These efforts have been highlighted by leading California organizations, including the Southern California Minority Supplier Development Council, WTS San Diego and the City of Los Angeles Public Works.

California Contractor #1107087

  • We’ve 100% owned this place since 1986. That means we approach every project with the heart and dedication of an owner. For the next day’s problem or the next decade’s vision, we work harder and smarter to consult, plan, design, build and deliver.

  • Our team received the Workplace Giving Campaign Award from Orange County United Way.

  • Each summer, our interns soak up knowledge, connect with colleagues and make an impact.

  • Fueled by the drive to strengthen communities, our employee-owners formed the Burns & McDonnell Foundation in 1988. Giving back isn’t an obligation of corporate culture around here. It’s a privilege and a personal commitment that beats in the heart of each one of us.

  • Burns & McDonnell hosted a Community of Inclusion and Equity Symposium. Together, attendees discussed best procurement practices for diverse businesses.

  • We’re engineers, architects, construction professionals, scientists and more. What do we all have in common? We care about each other, our clients and a job well done — to the benefit of our communities and the world.

  • We’ve built our business on respect, trust and equity — and consistently focus on making a positive economic impact in our communities.

  • We design and build the tangible and intangible, everything you see (and don’t see) that helps our cities thrive. We’ve worked relentlessly to make our clients and our communities successful since 1898, because we know safe, essential infrastructure is the foundation of a flourishing society.
