Our Story

Two Disciplines.

Based out of Moses Lake, WA, we operate across Washington State and beyond — going where the work demands.
In-House Survey
Our survey crew is on staff — not a subcontractor. That means faster turnaround, tighter coordination, and one throat to choke if something's off.
We Go Where the Work Is
Moses Lake is home base, but we're not limited to it. We've worked across Washington and take on projects wherever the scope makes sense.
One Point of Contact
You deal with us, not a chain of subs. From the first grade check to the final pour, you know exactly who's responsible.
Built for GCs
We understand how general contractors operate. We hit schedules, communicate clearly, and don't create problems for the rest of your project.
