Tetra Tech supports clients with alternative project delivery solutions for transportation infrastructure improvements.

Our interdisciplinary teams of professional transportation planners and traffic, highway, bridge, and asset management engineers are Leading with Science® by providing world-class technical services, ranging from artificial intelligence (AI) mechanisms for infrastructure assessments to predictive modeling for asset management to detailed 3D design modeling. Globally we maintain strong relationships with both public and private clients. Multi-year commitments and multiple national awards make us a trusted partner in delivering alternative delivery solutions.

Our experienced teams collaborate and contribute to fast-track transportation projects that address today’s challenges of moving people and goods. We support all project phases, from providing technical requirements and concepts for preliminary design for a client to advancing technical designs as a member of a design-build team and developing life-cycle maintenance plans for public-private partnerships.

Design-Build

Our global transportation team supports design-build delivery to provide innovation, and in many instances, significantly reduce construction timelines for critical projects. We coordinate with clients, contractors, stakeholders, and designers to advance plans for early material procurement and environmental approvals, and to organize, manage, and advance multidiscipline design efforts to meet construction time constraints.
