History of GRI.

When GRI founder’s Dave Driscoll, John Creveling, and Stan Kelsay decided to leave their respective larger companies, they came together to turn their dream of opening a small, employee-owned geotechnical engineering firm into a reality.

Today, GRI is home to more than 50 talented employees and four office locations. Our geotechnical, geological, pavement, and environmental engineering services have expanded to service a wide variety of market sectors. Although GRI has grown, we have held on to the small firm mentality and camaraderie that our founders valued so deeply.


2022 - GRI Moves to Tigard

GRI moved from our old office on Nimbus in Beaverton, to a larger, more expansive office space in Tigard. This new office space allows GRI to continue growing, gives our laboratory department ample space to work, allows us to park our FWD inside of our garage, and allows us to consolidate our archiving space from two locations to one.


2019 - Scott Schlechter, PE, GE, D.PE, Transitions to President of GRI

In 2019, Scott Schlechter was promoted to President of GRI. Scott joined GRI in 2000 after finishing his Masters degree in Civil/Geotechnical Engineering at Oregon State University and has spent his entire engineering career with GRI. Scott leads GRI’s earthquake engineering group and has completed seismic studies for many essential infrastructure projects. Before his promotion, Scott was a Board member for GRI and also currently serves on the national ASCE Coast, Oceans, Ports, and Rivers Institute committee.


2015 - Pavement Engineering Division Expansion

In September 2015, GRI welcomed Mike Maloney and Lindsi Hammond to the GRI team in our Beaverton office. Together, Mike and Lindsi brought an extensive background in pavement rehabilitation and design, pavement management, and nondestructive testing and analysis that greatly expanded GRI’s pavement engineering capabilities. In 2019, GRI added Todd Scholz  to expand the capabilities of our Pavement Engineering Division.

In addition, GRI acquired a KUAB 2m Model 150 Falling Weight Deflectometer (FWD) that fully complies with ASTM D 4694 and FAA AC 150/5370-11A. The FWD is capable of generating impulse loads in the range of 6,000 to 32,000 pounds, which covers the spectrum of loading typically seen from low volume roads to airports and heavy industrial pavements.


2012 - Brookings Office Established

GRI bridges the gap to Southern Oregon. In 2012, Chris Ell joined GRI and opened GRI’s new branch office in Brookings, Oregon. Chris brings strong analytical skills to projects with the firmwide resources of GRI.
