From an experienced team


We’re masters of exceptional site work, breaking boundaries, meeting timelines, and nailing project scope.

Ain’t no mountain high enough…that we won’t tackle with a dozer.

Koehn Construction is a skilled earthwork company that has state-of-the-art equipment to tackle just about any earthwork or site prep project. Excavation, demo, clearing, grading, drainage—have dozers, will travel. We also prep subgrade for building pads and pavement.

We self-perform earthwork on the design-build and design-bid-build projects we manage—but we’re happy to lend a hand as a subcontractor, too. Since we GC projects ourselves, we know what’s expected.

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; our earthwork contractors handle everything.

Great Quality, Every Time

We keep the big picture in mind on every earthwork services or prep project we tackle. 

Eliminating Unnecessary Expenses

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