Development of infrastructure in the circumpolar region demands specialized experience and technical competence. Tetra Tech has a well-earned reputation in the field of arctic geotechnical (permafrost) engineering, waste management at the community level, assessment of climate change vulnerabilities, and related services. Over the past 40 years, we have met the region’s most challenging technical demands for engineering, design, and construction of critical northern infrastructure projects.

Tetra Tech’s work spans a vast array of structures, including buildings, roads, dams, docks, bridges, airports, tank farms, landfills, and utility corridors. Project locations include the North American arctic regions from the west coast of Alaska to the east coast of Baffin Island, and to the extreme northern reaches of the high Arctic Islands. Tetra Tech has worked in the circumpolar regions of Greenland, Norway, and Russia.

Tetra Tech is a recognized leader in stabilization and remedial measures for structures on permafrost that are susceptible to damage by thaw settlement or frost heave. Our experience in foundation design includes insulated and ventilated pads, heat pipes (thermosyphons), rock socket and adfreeze piles (drilled and driven), footings, ground and rock anchors, machine base foundations, and earth-retained walls. Tetra Tech also provides services for environmental impact assessment, consultation, and permitting for all stages of development and project life cycle.
