Since 1987, TSI has been providing technically sound, innovative solutions in transportation planning and engineering for a diverse client group throughout the Pacific Northwest. Our staff brings over 100 years of experience to our client partnerships. TSI is proud to provide our clients highly responsive and expert services tailored to their unique needs. We believe our firm’s success is directly related to the quality and integrity of TSI’s staff. At TSI, professional integrity means solutions that work for the entire community. Our approach emphasizes more than problem solving, recognizing the need for managing processes as well as developing technical solutions. At TSI, we strive to develop a common understanding among the client team members, agency staff, and community groups; and clear, concise communication of the issues, alternatives, and solutions. We assist our clients from initial conceptual work, through the approval and design processes, the identification of pertinent issues and the implementation of practical and cost-effective solutions. TSI has successfully completed hundreds of projects in both the public and private sectors, often under critical time pressures involving complicated decision-making. In the public sector, we have met the budget, time, quality, and reporting requirements of federal, state, and local government agencies. In the private sector, we have met the needs of clients by meeting budget guidelines and improving efficiency.
