As pioneers in engineering, science, and construction consulting services in the North, Tetra Tech has a proven reputation for successful development in arctic conditions.

The circumpolar region comprises arctic areas and southern expanses of permafrost around the globe. The region is remote with an extreme climate. The social and physical environment is both fragile and complex. The negative impacts of climate change are readily evident, given that frozen ground is necessary for the strength and reliability of infrastructure built here. For more than 40 years, Tetra Tech has helped connect and explore this rich, magnificent, and fragile world.

Tetra Tech provides adaptive engineering and scientific services that reach beyond traditional approaches. Our capabilities include full life-cycle services for development of northern public transportation, mining, energy, and other infrastructure projects. Our team provides specialized consulting and construction services, including full-service environmental engineering, procurement, and construction management (EPCM) solutions.

Tetra Tech maintains strong relationships, local presence, and aboriginal partnerships in northern Canada and Alaska to support our public and commercial clients. With offices throughout the region, Tetra Tech provides full-service delivery to address challenges throughout all stages of a project—from initial planning, concept, exploration, and preliminary economic assessment phases; through approvals and permitting, design, construction, operation, and closure or reclamation.
