Mining in the Circumpolar Region
Tetra Tech provides full lifecycle services for northern mining operations and associated support infrastructure in the world’s circumpolar regions.
In addition to our full-service consulting, engineering, and construction services for the complete mine life cycle, Tetra Tech’s circumpolar team specializes in consulting for mines in extreme northern and arctic conditions. We meet challenges that include remote locations, fragile environments, complex regulatory systems, harsh temperatures, groundwater and surface water management, and addressing the impacts of climate change. Tetra Tech provides specialized design and constructability approaches that are required for permafrost. These require mine structures, plant foundations, and associated facilities such as roads, airstrips, tailings and waste disposal areas, and overall protection of the environment.
Tetra Tech has the experience and expertise to help address the challenges posed by climate change. Through our work at numerous projects in Northern Canada, Alaska, Greenland, and Siberia, Tetra Tech understands how to plan, permit, design, and construct mines in some of the most hostile environments on the planet.
With a 40-year history in the north, Tetra Tech is a leader in providing innovative design and construction expertise to arctic mining projects. We have strong relationships, local presence, and aboriginal partnerships in northern Canada and Alaska.
