About Koehn Construction Services

We're in the People Business.We Happen to Build Buildings.

The craft. The challenge. The relationships that outlast every project. That’s why we build.

Since 2003

The story behind
the company.

Koehn Construction Services was founded in Fredonia, Kansas in 2003 by people who believed they could do the work better than what the industry was offering.

The first year

They set goals they thought would take twelve months. They hit them in three. That pace hasn’t slowed down since.

What came next

A second office opened in Tulsa. The team grew. The projects got bigger, and the markets multiplied — but the ambition stayed exactly the same size it was on day one.

Today

The core of it hasn’t changed. KCS is still a company that sets a target, exceeds it, and immediately asks what’s next.

Why We Build

A purpose that goes beyond the build.

KCS isn’t just building buildings. The purpose behind the work is real: we love to build – buildings, teams, careers, and the communities we operate in. We love the problem-solving, the progress, and the mastery that comes from doing something hard and doing it well.

That’s not a tagline. It shows up on the job site every day – in how the team runs a project, how they treat a client, and in the standard they hold each other to.

The Values That Drive the Work

Four values. Proven on every job.

Dependability

Clients come back because they know what they’re going to get. On budget. On schedule. The same standard every time. Dependability isn’t a promise KCS makes at the start of a project; it’s what gets proven by the end of it.

Gets It Done

There’s no shortage of contractors who are good at starting work. KCS is built around finishing it. When something gets hard, the team finds a way through. That’s not a personality trait – it’s a company standard.

Acts With Integrity

It’s in the tagline for a reason. KCS tells clients the truth before they sign the contract, during the build, and after the keys are handed over. If something isn’t right, we say so. That’s what integrity looks like in practice.

Problem Solvers

Every project hits a wall. The question is whether your contractor brings problems or solutions. KCS brings solutions – backed by field experience that knows how to work through what comes up.

The Team Behind the Work

People you can
count on.

The capabilities are real. The self-perform trades, the design-build process, the regional footprint – those matter. But none of it happens without the people running the jobs.

KCS has built a team that takes ownership. Not just of the project, but of the outcome. That means showing up prepared, communicating clearly, and finishing what gets started.

From the first Sales Team meeting to the final walkthrough – our team has the drive to get it done.

The Standard We Hold Ourselves To

Excellence isn’t a word KCS throws around. It’s the standard – on the job site, in the budget, on the schedule, and in how the team shows up for clients.

Every project has three non-negotiables: budget, scope, and timeline. We don't pick two.

We finish what we start. And we make it look easy – not because the work is simple, but because the right team knows how to carry it.

Where We Operate

Two offices.
One company.

KCS operates out of Fredonia, KS and Tulsa, OK. From those two offices, we manage commercial, industrial, and aviation projects across Kansas, Oklahoma, and Missouri — from Southeast Kansas and Wichita to the Kansas City metro, Tulsa, and the Joplin/Springfield corridor. Both offices run full project operations. If your project is in our region, we can build it.

Common Questions

Common questions about Koehn Construction Services.

KCS was founded in Fredonia, KS in 2003 by Lyle Koehn. The company started with a small team focused on doing commercial and industrial construction better than the status quo. The Fredonia office is still our headquarters. Our second office is in Tulsa, OK.

Commercial, industrial, infrastructure, recreational, and institutional projects across Kansas, Oklahoma, and Missouri. New construction, additions, renovations, and full site development. We deliver through design-build, general contracting, and construction management – and self-perform earthwork, concrete, and site utilities on most projects. See our capabilities page for the full breakdown.

A few things. We self-perform the trades that most GCs subcontract: earthwork, concrete, and site utilities. We’re relationship-first, not transactional. Most of our work comes from clients who’ve built with us before. And we’re regionally rooted in a way that national firms can’t replicate.

Yes. We operate out of two offices – Fredonia, KS and Tulsa, OK – and build across a region that includes Southeast Kansas, Wichita, the Kansas City metro, Tulsa, and the Joplin/Springfield area.

We don’t treat projects as transactions. We treat them as partnerships. That means asking the right questions before proposing a solution, staying accountable through every phase, and following up after the job is done. Most of our work comes from clients who come back, and that’s the metric we care most about.
