Portland International Airport

Portland International Airport
Portland, Oregon

The principals of GRI have provided geotechnical, environmental, and seismic-related consulting services to the Port of Portland for over 40 years, including 10 years prior to the founding of GRI. The geotechnical services have primarily involved floodplain and waterfront developments along the Columbia and Willamette Rivers. Notable projects include concourses, parking structures, and roadway expansion projects at Portland International Airport; multiple water-transportation terminals, wharves, bulkheads, and docks; various industrial developments and office parks (structures, foundations, piers and piling, parking lots, roadways, embankments, infrastructure design); and numerous projects involving rivers, including bank stabilization and dredging projects. For most projects, GRI conducted preliminary and/or detailed final geotechnical investigations and provided design recommendations, including review of construction documents and construction observation services for the new facilities.
