Client: The Virginia Department of Transportation (VDOT)
ATCS is helping support VDOT on this 22.5-mile widening and managed lane project on I-66 in Northern Virginia. Our responsibilities include project management and delivery services, technical noise analysis lead and support role, and operational assistance. More specifically, we are providing noise analysis guidance and support, technical management, review services, and project delivery assistance to ensure the Final Design noise analysis complies with VDOT’s latest Highway Traffic Noise Impact Analysis Guidance Manual. We have performed a series of technical reviews in support of the Final Design noise analysis to ensure compliance. In addition, we evaluated noise abatement recommendations proposed by the contractor to ensure acoustical benefits were maximized and performed a series of reviews on all project-specific TNM noise models to ensure each meet current standards and best modeling practices.
