Brief History of the Firm. Founded in 1958 by Carnegie Mellon University engineering graduate students, GAI developed a strong professional reputation in foundation engineering by supporting the needs of nationally-recognized industrial and energy clients. In the late 1960s, and in response to urban growth and mounting environmental regulations, GAI diversified into transportation and land development while adding niche services in survey, environmental studies, and cultural resources, setting GAI apart from more traditional engineering firms. Strategic decisions to open offices located near our clients in growing markets throughout the U.S. led to the rapid growth of our firm. Corporate-wide consolidation of strategic acquisitions diversified our firm and transformed GAI into a premier engineering, planning, economic and environmental firm in the U.S. and abroad.

We are engineers, planners, archeologists, surveyors, and environmental specialists. We are technicians, designers, administrators, and communicators.

Here at GAI, we offer you the opportunity to work, learn, grow, and lead in a supportive environment alongside accomplished colleagues. 

60 years strong and 100-percent employee owned, GAI is the right place for talented and motivated individuals who seek to distinguish themselves in a company poised for unlimited growth.

“GAI has a Corporate philosophy of encouraging a culture of giving back to the communities we serve. I’m very proud of the effort our staff made for The United Way as the firm’s 2017 Charity of Choice along with all the other year round charitable activities that have occurred!” - Gary DeJidas, PE, Chairman & CEO

GAI is proud to support and encourage employee involvement in philanthropic efforts, including our annual charity of choice partnership as well as mentorships, volunteerism, and participation in community events in various cities, townships and municipalities in which we live, work, and play.

  • “iGaive” is GAI’s corporate flag for giving—an acknowledgement of a generous and caring team spirit. This employee-driven initiative was sparked by a special class project under GAI’s Leadership Development program.
  • GAI employees give from the heart year-round. Whether a “Pass it Forward” act of kindness in their immediate community, or a compassion for others wherever they may be, giving is part of our corporate culture.
  • That we “make a difference” is more than client-speak at GAI—it defines our corporate family.

    I have been working at GAI Consultants full-time (More than a year)


    Supportive of professional development, ability to work across a diverse range of projects and industries, and some interesting team-building initiatives. There always seems to be events in the offices for special occasions, holidays, etc.

    Company will host programs that can apply towards professional certification development hours.

    Benefits seem to be competitive within in the engineering field.


    Not that I have come across.

    Advice to Management

    Overall culture continues to improve over the past few years from what I have heard and seen.

    Make development opportunities more visible.

    I applied online. I interviewed at GAI Consultants in September 2017.


    Initial phone interview with the company. They wanted to know my background and where I would fit in with their company. Their primary goal was to look for a engineering manager. However, they were also interested in some of my other skillsets.
