Our Portland Offices

Working in Portland

Our Main Office is in Portland.  

This region can attest to much of our experience.  We have performed work in mountainous, silt plains, lava flows, volcanic formations, landslides, cityscapes, riverbanks, floodplains, and coastal areas—all within a 100-mile radius.  

We are listed as a COBID-Certified business in Oregon, and operate throughout the Pacific Northwest and beyond from our Portland Office.  We have seen continued growth in this region and give that geotechnical engineers are the “first in” when it comes to construction, we do not foresee any signs of a slowdown soon—and this is a great opportunity to be part of this booming community.

Why Portland?

This firm was founded in Portland, and the city is home to an amazing climate, geography, and a year-round construction season.  It is constantly ranked as one of the top growing cities in the country, and its culture, attention to environment, and friendly professional community have boosted our firm to become a strong competitor in the local market.

Our Principal and Owner worked for the Portland District of the US Army Corps of Engineers, and founded Central Geotech on the principles of hard work, solid reputation, prompt responsiveness, and service.  Portland embraces this relationship-based approach, and upholds the importance of our profession through robust regulation and permitting requirements, allowing geotechnical engineering be a critical part of the huge ongoing construction economy.

Our Customer Testimonials

“Needed a soil investigation and Geotechnical Report fairly quickly as well as construction monitoring for some urgent work. Central Geotechnical Services took care of everything I needed to help expedite the permit process as much as possible, was there monitoring the work and has helped me get permits closed out. I will definitely enlist them on future projects.”

Brad Neu, Catworks Construction

This became valuable as I shared detailed information with my senior leadership. It has been a pleasure to work with such a professional firm and I will recommend them to others.”
