About K3

K3 stands for three Kauffmans… Phil, the founder, and his two sons, Dustin and Matt.

Phil grew up on a dairy farm in Wisconsin. He inherited a farmer’s work ethic from his father, and his father’s father, but he didn’t share their passion for cows. So in 1995 he moved to Oregon and started working for a construction company in the small town of Halsey.

Before long he was managing the business, expanding the company’s services and nurturing growth.

In 2007 Phil earned himself a partnership. A few years later he bought the company outright and renamed it Blackstone Construction.

Phil isn’t the type to sing — or even hum — his own praises, so if you ask him about Blackstone’s success he always attributes it to his team.

"Let’s be honest… Many excavating crews look a bit unruly, like you might not want them hanging around your home or your construction project,” Phil said. “I guess maybe I’m just more particular about who I hire. I’ve always found really good, reliable people who show up on time and do what they say they’re going to do.”

In 2018 Phil decided to sell Blackstone and move his family to Madras. That’s when he started K3 construction with his son, Dustin and nephew Jeremy.

“We run a tight ship based on a solid foundation of Christian ideals and good old-fashioned, handshake service,” Phil says. “Our haircuts kind of give us away. 

K3 is probably the only crew in Central Oregon where you still routinely hear “yes sirs” and “thank you maam’s”.

With K3 you get the most rock-solid guarantee in the business. We can do that because we lay the groundwork for your satisfaction from the very first phone call.

We stick to a disciplined, thoughtful process that produces a lot of happy customers. Here’s who we serve:

General Contractors who are looking for the most reliable subs in Central Oregon. As a subcontractor K3 fits best with Generals who need site prep work on smaller commercial projects or modest residential developments.

Project Managers that also need help with site planning, scheduling and execution. We leave no stone unturned in order to get your project completed on time and on budget, every time.

Real Estate Developers who are trying to wear many different hats. We listen intently, study the site carefully, and consult on a detailed plan and schedule. Then we communicate exactly what’s going to happen, step by step, so there are no surprises. It’s who, what when and where, exactly.

No one else goes as far to make sure you’re happy.

For a fairly small, family-owned excavating and paving business, we fight way above our weight class. You’ll be very surprised by what we can do.
