Armstrong Consultants, a Grand Junction-based aviation engineering and planning business, has passed the 50-year milestone in operations.

Founded in 1973 by Ed Armstrong, what started out as a civil engineering business developed into firm specializing in planning, engineering and construction administration for airports.

Armstrong Consulting evolved alongside the aviation and transportation industry to offer services to general aviation, business jet and commercial service airports as well as military airfields. Today, the firm  serves airports across the region, including a total of more than 130 clients in Colorado as well as Arizona, California, New Mexico, Nevada, and Wyoming.

The business is expected to expand further following its acquisition late last year by H.W. Lochner, a national infrastructure consulting firm.

“Armstrong has experienced tremendous growth and expansion over the past 50 years, and we are proud of the work we have done to support so many airport communities,” said Dennis Corsi, president of Armstrong Consultants. “Moving forward, our focus will remain on providing personalized client attention and delivering the highest quality results for each airport we serve.”

Chris Nocks, engineering operations manager, agreed. “Lochner’s acquisition of Armstrong provides our team with an expanded set of resources and capabilities that enable us to continue to elevate our service and quality. It is an honor to celebrate 50 years in business, and we are excited about the bright future ahead.”

Armstrong Consultants has worked on a total of more than 3,000 projects at airports across the Western United States. In addition to Grand Junction, the firm operates offices in Denver and Phoenix as well as Albuquerque, N.M.; Casper, Wyo.; Reno, Nev.; and Santa Rosa, Calif.

Founded in 1944 and based in Chicago, Lochner provides construction engineering and inspection, design, environmental and planning services to the transportation industry. Lochner has supported general aviation and commercial airports since the 1960s. The company ranks 128th in the Engineering News-Record list of the top 500 design firms.
