About Us

Tetra Tech has provided premier consulting engineering and technical services to support sustainable development throughout Asia for more than 20 years.

As Asia’s economies return to healthy growth, the region’s attention has shifted to bolstering resilience to major storm events; protecting vital resources; and ensuring availability of clean, affordable energy. Tetra Tech’s experts work in partnership with countries, multilateral banks, and international development assistance organizations to address these and other complex challenges.

Many governments in Asia face immense political, social, economic, and infrastructure challenges while balancing demands for transparency, accountability, economic opportunity, and inclusive participation of marginalized populations, especially women and youth. Tetra Tech is an implementing partner of the U.S. Agency for International Development in multiple Asian countries, notably India. Our expert teams are working with municipal, provincial, and national government authorities to improve delivery of public services; engage stakeholders; and develop and expand water, power, and transportation infrastructure.

From early efforts to prevent air and water pollution in India to today’s most renowned high-performance buildings in South Korea’s Songdo International Business District, our cutting-edge services protect and enhance both the natural and built environment throughout the region.

We offer comprehensive services for public-sector and commercial clients throughout Asia from our offices in India, Indonesia, Japan, South Korea, Philippines, and Thailand.
