About Us


Douglas J. Nicholls, PE, RLS, founded Core in February 2004. In the years since, he has surrounded himself with talented colleagues and an impressive roster of collaborative firms. This exceptional team has established Core Engineering Group as a preeminent provider of civil engineering and land surveying services.

Core Engineering Group’s technical expertise is extensive. Our experienced staff is well positioned to tackle any civil engineering or land surveying project, and diverse examples of our successful work are visible throughout Arizona, Southeast California and even Mexico.

No matter what the project -- from lumber yard to interstate -- what sets us apart is a commitment to communication. When Core takes on your project, our team members will provide personal attention from start to finish. This allows us to ensure we meet your schedule, your budget and deliver the results you need.

Our Employees Set Us Apart

Core Engineering Group’s greatest asset is outstanding people. That’s why we were proud to be singled out as a great place to work, receiving the Yuma Sun’s 2010 Small Business Workplace Excellence Award.

Our firm was nominated by employees and touted in the judging process as being hard working, professional and pleasant. It wasn’t the first time Core was singled out. We were runner-up for the Workplace Excellence Award in 2008 and 2009.

As a firm that prides itself on customer service, we think happy employees mean happy clients.
