CommercialConstruction Services.Built to Handle More.
Big schedules. Tight budgets. Complex builds. Koehn Construction Services handles it.
The Capability to Build It Right
Every project has three non-negotiables: budget, scope, and timeline.
KCS brings the delivery methods and the trades to the same table. Whether you need a design-build partner from the first conversation or a commercial general contractor to execute a finished set of plans, we have the capability and the crew to back it up.
How We Deliver
Design-Build
One contract. One team. One point of accountability.
We manage design and construction together - which means faster timelines, real-time budget control, and no gaps between what was drawn and what gets built. If you know what you need but want a partner to figure out how to build it, this is where to start.
Explore Design-Build →General Contracting
You've got the plans - we know how to build from them.
Bring us your completed construction documents and we'll put the right people on the job and manage it to completion. Tight schedule. Accountable execution. No surprises at closeout.
Explore General Contracting →Construction Management
The earlier we're involved, the better your project goes.
Construction management works best before the budget is set and the drawings are done. We help owners evaluate design decisions, control costs during development, and keep the project on track before it ever gets to bid.

Trades
Earthwork
Site prep that sets every phase up for success.
Our crews handle grading, excavation, and site preparation with the equipment and experience to get it right before anything else gets built. Solid groundwork isn't optional - it's where every good project starts.
Explore Earthwork →Site Utilities
Underground infrastructure you can depend on.
We self-perform storm, sanitary, and water utility installation so the coordination between your earthwork, utilities, and concrete stays in-house. Fewer moving parts. Better scheduling. One crew that understands how all three connect.
Explore Site Utilities →Concrete
Foundations and flatwork built to last.
Our crews self-perform concrete foundations and concrete paving for commercial and industrial projects. From slab-on-grade to heavy-duty industrial paving, we control the quality and the schedule from pour to finish.

We Do the Work
KCS self-performs earthwork, concrete, and site utilities on commercial projects across Kansas, Oklahoma, and Missouri. That means the trades doing the work are Koehn trades - accountable to the same schedule, the same budget, and the same standard as the rest of the project.
Fewer handoffs. Tighter control.
Better outcomes.
