Expertise in Beaverton's Development Landscape

With decades of work in the Portland metro area, we have a deep and practical understanding of local soil conditions, seasonal weather patterns, and the specific municipal codes and regulations in Beaverton and Washington County. This local knowledge is invaluable; it allows us to anticipate challenges with soil stability, manage water runoff effectively during the rainy season, and navigate the permitting and inspection process smoothly. This expertise helps prevent costly delays and ensures your project complies with all local requirements from day one.

Value Engineering: A Proactive Partnership

This isn’t an add-on service; it’s how we operate. From the moment we join your team, we review project plans from an owner’s perspective. We leverage our four generations of field experience to identify opportunities to improve efficiency, reduce costs, and mitigate potential issues before they arise. For a Beaverton project, this could mean suggesting an alternative grading strategy that balances cut-and-fill to eliminate the need for expensive material import/export, or proposing a different utility layout to avoid difficult soil strata. This insight is a standard part of our commitment to your project’s success.

Our private fleet of over 150 units—including Super Solos, Truck and Pups, Transfers, Side Dumps, End Dumps, and Lowboys—is a critical component of our ability to keep Beaverton projects on schedule.

When we need to move heavy equipment to a job site or haul thousands of yards of soil, we have the dedicated resources to do it immediately. This control ensures materials and equipment are where they need to be, when they need to be there.
