Our story in aviation started in 1976 with a focus on military and airfield projects, driven by founder Bob MacArthur, whose background in the U.S. Air Force shaped a commitment to excellence. We’re proud to design infrastructures that support the future of flight.

Behind every great project is a surveyor who mapped it first. This Surveyors Week, we’re celebrating the people who turn plans into reality. Thank you to our amazing crew!

Happy St. Patrick’s Day! 🍀 We celebrated with loaded baked potatoes and a scavenger hunt! We hid tiny Saint Patty’s Day birds around the office, and the more you found, the better your chance to win the pot of gold! Congrats to Amanda Durst for taking home the prize!

Celebrating Engineers Week at MacArthur! We kicked things off with a yogurt bowl breakfast, fueled up with a pizza day, and had two awesome high school students join us for Engineer for a Day. Thank you to all of the amazing engineers at our company for everything you do!
