A brief history of PEC. Relax. There won't be a test.

In 1965, Professional Engineering Consultants, PA was created by the merger of three engineering design firms. These three firms combined their capabilities to establish one professional association:

  • Hysom and Peugh—mechanical consulting firm
  • Hartwell and Baxter—structural engineering firm
  • Howard Bridges—electrical engineering firm

By 1970, PEC offered mechanical, electrical and structural facilities engineering services and the civil engineering services of transportation, environmental and land development.

Our roots are in downtown Wichita, KS, where our headquarters remain today. We like to be in the middle of things, and we've had a strong commitment to downtown development from the very beginning. 

Our downtown urban roots are part of our vibe. We like it here.

Mad scientists are added
In 1973, we created our PEC Field Services division, which added geotechnical engineering services, inspection and testing to our engineering menu in Wichita. If you want to know the exact contents of your asphalt mix, or how much stress those concrete slabs can take before they break—they're your people.

Our home office has been at 303 S. Topeka since 1989, when we purchased and renovated the former Price Auto Service building.


Prior to our ownership, the building was best known for a catastrophic fire in 1947. We're happy to report that it has now been catastrophe-free for the 30-something years we've been here. And we've never tried to sell anyone a car.


But enough about ancient history
Today, we have Kansas offices in Topeka, Lawrence and Pittsburg, along with our Tulsa and Oklahoma City, Oklahoma locations and Fort Collins office in Colorado.

In those offices are 275 employees of all stripes. That's a lot of pocket protectors. We design all kinds of projects, from interstate interchanges for the Kansas Department of Transportation, to aircraft manufacturing and testing facilities, to water treatment systems that can make salty water drinkable.

And we must be pretty good at it, because our clients keep coming back.

Join 'em, why don't you?  We'll take good care of you.
