As a leading implementing partner for the U.S. Agency for International Development and the Millennium Challenge Corporation, Tetra Tech brings international expertise in engineering and architecture to deliver sustainable designs that address infrastructure challenges in developing countries.

Tetra Tech’s architects and engineers help provide access and improvements to infrastructure such as safe drinking water, sanitation, roads and bridges, health clinics, schools, government buildings, and reliable sources of energy around the world. Our services are essential in helping governments and communities achieving their goals in health, education, economic growth, food security, climate change, and post-conflict and post-disaster reconstruction.

We engage with stakeholders to provide capacity building through formal or on-the-job training, internships, mentorship programs, and integration of our work with host nation staff wherever possible. Our teams also work closely with the responsible local governments and institutions to build their financial and managerial capacity for operations and maintenance to ensure long-term sustainability of donor-funded infrastructure projects.
