CEC began as a corporation in 1974 with two employees, Bill Brown and Harry Walsh.
By 1981, CEC expanded to 10 employees and completed construction on its new facilities at 3608 Fernandina Road, where the company expanded further and developed a long list of repeat clients.
In 2015, after long and successful careers, Bill and Harry both retired, transferring ownership of the company to 3 employees: Bill Flowers, Josh Rabon, and Clay Walsh.
By 2017, CEC had outgrown its space at 3608, and relocated to 3740-A Fernandina Road.
CEC currently employs 38 people, with 4 registered engineers and 2 licensed surveyors.
