The ground work is where it all begins.

Our crew is back on site at Casey’s in Central City prepping for the installation of 5 ADS StormTech® SC-800 chambers. You can see the excavation, geotextile fabric, and gravel bed all being laid out and getting ready for the big install. Meanwhile, the Casey’s building is really starting to take shape in the background!

Big equipment, a solid crew, and a lot of gravel. That’s how we do it. 💪🏻

means being part of a crew that takes pride in the work, trusts each other to handle the job the right way, and shows up ready to keep projects moving no matter the conditions.

It’s built through long days, good people, and the standard our crew holds itself to every time we step on a jobsite.

Building a strong reputation in civil construction takes more than moving dirt. It takes the right people, the right equipment, and the ability to handle projects that come with tight schedules, changing conditions, and a lot of responsibility behind every decision made on site.

Over the years, we’ve been fortunate to earn the trust of contractors, developers, and communities across Eastern Iowa by continuing to take on bigger challenges and delivering work we’re proud to put our name on.

Thank you to everyone who has supported Koelker Excavating over the years and helped us continue to grow.

Tank setting day in Central City. The underground fuel tanks for the new Casey's are now installed, a key milestone that pushes the project into its next phase.

From excavation and base prep to crane placement and backfill, this process requires coordination and accuracy at every step. From here, the focus shifts toward utility tie-ins and building preparation.

Appreciate the work from OWL Services, Martinson Construction, and Barnhart to get it done right.
