At Tetra Tech we use our Leading with Science® approach, combined with our local knowledge and experience and our Tetra Tech Delta suite of technologies, to develop solutions to optimize the way our clients manage their transportation assets. Our services cover the full asset life cycle, including asset condition assessments and monitoring, performance modeling and forecasting, asset management planning, and asset improvement program implementations. We customize solutions by incorporating the latest technologies to help our clients make informed decisions to economically and responsibly sustain their transportation infrastructure assets.
Climate Resiliency and Adaptation
Our approach to resilient asset planning is to determine the additional resiliency that can be economically justified to reduce vulnerability using a risk-based analysis process by monetizing the risk of a potential climate event. We establish the magnitude and likelihood of extreme climate events, such as flooding and wildfires, by locally applying global climate prediction models. The climate risk is combined with other risks to calculate an appropriate level of adaptation. Assets include:
Transportation Corridor Condition Assessments
We recognize that accurate asset condition assessments form the foundation for successful asset management planning. Tetra Tech has invested in industry-leading non-destructive transportation corridor data collection technologies. Our team of diverse specialists provide innovative, off-the-shelf custom-designed solutions to meet client-defined objectives. We collect and provide accurately referenced, high-quality data to understand the health of our clients’ transportation networks.
