Geotechnical Exploration


Prior to design and construction, exploration operations typically involve getting an understanding of the subgrade soils at necessary depths in preparation for design.

This can include drilling, test pits, cone penetrometers, or other tools, depending on what the project requires.

Assessments and investigations come in very different packages to help specifically cater to each Client.  We can even provide a Preliminary Assessment to help discover possible issues with a site before moving forward with more detailed investigation and testing.

The Permitting Process


If you have recently been to a County or City office, it can be a frustrating experience--especially if you've been told that you need more items submitted in order start building.

You are not alone.  We can help you figure out the details of the permitting requirements and get you going again with the right report you need, and perform work in phases, so that expenses can be carefully managed.

We provide services within any jurisdiction in Oregon and Washington.

Construction Services


At the beginning of your project is a soils investigation to discover the necessary geotech requirements for building onsite.  


Moving forward with construction involves site work to help guide a builder with earthwork and foundation placement considerations.  These involve the proper placement, sequencing, or construction requirements regarding fill soils, drainage, or foundation bearing surfaces.  

Onsite Construction Services Include:

  • Compaction Testing

  • Proof Rolls

  • Fill Placement Guidance

  • Special Inspection

  • Asphalt Testing

  • Construction Observation

  • Earthwork Design Guidance

  • Foundation Assessments
