Tulsa, Oklahoma

We opened our Tulsa location at the start of 2025 to expand into this larger market, since we already have team members living in this area. Our plan is to have full pre-construction, project management, superintendent, and self perform crews working from this office and local to the area.

We believe in building strong relationships which includes our clients, our vendors , and our team members. Koehn Construction Services offers hands-on training, career growth opportunities, and core values that express who we are as a team.

Let's Talk

Whether you just need earthwork services or a full design-build team, Koehn Construction Services is ready to build with you.

We Handle Our Own Schedule

We hate project delays as much as you do, which is one of the many reasons we don’t let subcontractors dictate scheduling.

Great Quality, Every Time

Our concrete foundation contractors keep the big picture in mind on every earthwork or prep project we tackle. 

Eliminating Unnecessary Expenses

One of the main reasons we self-perform foundation and concrete services is to save you money in the long run.
