Tetra Tech’s engineering and architecture experts deliver sustainable designs that address infrastructure challenges in developing countries around the world.

As a leading implementing partner for the U.S. Agency for International Development and the Millennium Challenge Corporation, Tetra Tech helps 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 achieve 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.

Our Expertise in Infrastructure

Tetra Tech’s approach ensures that planning activities remain focused on developing infrastructure that has long-term viability after donor organization financing has concluded. We use data related to climate resiliency, seismic requirements, and sustainability to determine project priorities, prerequisites, and project phasing. Tetra Tech also recognizes the critical importance of gender inclusion towards achieving economic growth and seeks to involve women—as members of local engineering teams, community stakeholders, or local government representatives—in all aspects of infrastructure project planning activities.

Planning activities that gain broad consensus from the community result in infrastructure that lasts for decades and maximizes the economic rate of return for the initial investment. We strive to apply the principles of climate resilience, seismic design, and operational sustainability during planning activities so that they remain core tenants throughout the life of the project.

Tetra Tech develops context-appropriate designs that meet international standards, incorporate locally available materials, match local labor capabilities, and require a low level of operations and maintenance. Our understanding of local social, environmental, and economic factors informs our designs and ensures they are robust and can be implemented in each circumstance.

Tetra Tech’s designs meet a mixture of U.S. and international codes as well as local government and donor agency standards. We apply lessons learned from planning activities and previous experience to develop designs that are optimized for each project’s objectives.

Tetra Tech takes gender dynamics into account for all design activities to anticipate the effects of infrastructure on both men and women. We encourage and seek active participation by women during the design process, including activities related to stakeholder engagement, to ensure we are appropriately incorporating the needs of entire communities for use of infrastructure projects.

Tetra Tech provides construction monitoring and oversight services with a focus on training and capacity building to maximize investment and improve local contractor capabilities. We specialize in upholding quality control and quality assurance measures and focus on identifying reasonable solutions to issues that develop throughout the construction phase.

We provide detailed oversight of the construction phase, which is critical for maintaining compliance with U.S. and international codes and standards and maintaining adherence to drawings and specifications. We also train local construction contractors and build their capacity to ensure quality assurance and quality control and promote project sustainability after construction is complete.

We assist clients with identifying and managing their environmental and social impacts and risks throughout the project life cycle. Our environmental specialists, social scientists, and engineers work as a fully integrated team to advance projects by avoiding or minimizing potential consequences of proposed infrastructure projects on communities and the natural environment.

At every stage of the project, we engage with local governments, regulators, and community stakeholders to help our clients not only obtain required regulatory consent but gain essential community buy-in needed for long-term sustainability.

Tetra Tech supports involuntary resettlement activities that result from infrastructure improvement projects. In accordance with International Finance Corporation Performance Standards and World Bank Guidelines, our resettlement specialists are dedicated to reducing displacement through alternative routing, when possible. When displacement cannot be avoided, we work to minimize adverse social and economic impacts and improve or restore the livelihoods and standards of living of displaced persons.
