OUR SERVICES
Geotechnical Engineering
Since GRI’s founding in 1984, we have been providing full-service design, permitting, and construction support services for geotechnical-related projects throughout the Pacific Northwest and worldwide. From bridge design to ground-improvement recommendations for municipal buildings and transportation infrastructure, our company’s geotechnical team offers a vast encyclopedia of experience and knowledge for helping our local, state, and federal clients meet their project goals and timelines. Our geotechnical engineering services offer our clients the opportunity to quickly and cost-effectively evaluate, design, permit, and manage construction of a wide range of soil-, rock-, and groundwater-related projects.

Pavement Engineering
Our pavement engineering team has extensive experience with pavement evaluation, design, pavement management, forensic investigations, and construction management services. Our projects range from low-volume roads, gravel roads, or parking lots to heavy-duty pavements for interstate highways, airfields, and industrial port facilities. We have provided services to public sector clients at the federal, state, and local levels, as well as in the private sector. Our wide array of pavement-related projects have assisted clients in developing practical, cost-effective solutions that improve pavement performance, promote sustainability, and reduce the overall life cycle cost of their pavement assets. We are also experts at implementing and updating pavement management programs in order to help develop long-term pavement management strategies for agencies capital improvement plans (CIP).

Geologic Hazards
Our team’s geological hazard experience includes geotechnical hazard management, expansive soils, mitigation, landslide evaluation and remediation, slope protection/stream restoration, dewatering, deep excavations and shoring, environmental hazmat services, and ground improvement. For most projects, GRI personnel are involved in all phases of the work from preliminary investigation through field observation and testing services during earthwork and foundation construction. As a result, our staff has a keen appreciation for the relationship between design and construction and the importance of developing designs that are cost-effective and constructible.

HazMat
GRI has a long successful history of working on hazmat projects. For over 30 years, we have helped public and private clients successfully manage their environmental considerations -- we have worked on ‘Brownfield’ sites before the term was coined. Our ability to collaboratively perform hazmat site evaluations in conjunction with geotechnical work saves clients time and money. We provide our clients with solutions for due diligence, characterization, permitting, and regulatory closure for projects with soil, groundwater, or sediment considerations. We take pride that we have helped close and repurpose numerous hazmat sites that are now hidden amenities of our local communities.
