Tetra Tech has distinguished itself by providing professional service, timely information, and high-quality documents under difficult and aggressive schedules. Tetra Tech has clearly demonstrated that it has the management capability and depth of resources to support USACE on multidiscipline-type projects and in locations throughout the world. The collaboration and harmony exhibited by USACE, Millennium Challenge Corporation, and Tetra Tech staff to complete this difficult project is an exemplary example of how projects should be performed.

Millennium Challenge Corporation’s (MCC) Secondary National Roads Development Project aims to reduce transportation costs and promote economic development through rehabilitating an existing 222-kilometer road in Samar and Eastern Samar Provinces in the Philippines. By reducing travel times for both passengers and goods, and by achieving savings in vehicle operating costs and road maintenance costs, the investment will facilitate commerce between the provinces of Samar and Eastern Samar and, ultimately, increase local incomes.

The MCC retained Tetra Tech under a U.S. Army Corps of Engineers (USACE) contract to perform feasibility studies, design the reconstruction and rehabilitation of roads, design drainage improvements, reconstruct bridges, stabilize landslide areas, and implement roadway safety measures. This project is also one of MCC’s early efforts to use global climate models to predict project risks.

Tetra Tech evaluated climate-related risks and identified key climate-proofing measures such as developing project-specific design criteria for drainage infrastructure and sea level variations, improving hydraulic capacity and embankment protection at bridges, and enhancing roadway pavement and shoulder design to withstand flooding. The road successfully withstood one of the strongest typhoons ever recorded (Super Typhoon Haiyan in 2013) and is currently playing a vital role in the region’s recovery. Tetra Tech’s experience proves that implementing climate change risk-management strategies contributes to the overall resilience of the project and, therefore, its long-term sustainability.
