Post Construction Analysis of Major, Mega and Regionally Significant Projects

This project will develop a framework (methodology) for evaluating post-construction outcomes of Major, Mega, or regionally significant projects. Evaluation metrics may include but are not limited to: efficiency in project delivery, effects on traffic mobility, safety, and economic impact. The framework developed by this project is intended to be implemented by future Major/Mega/regional projects to improve the transportation project delivery process. Wisconsin Department of Transportation (WisDOT) measures performance through state performance measures, MAPSS (Mobility, Accountability, Preservation, Safety and Service); federal performance measures (e.g., reliability, emissions, delay, etc.); and other continuous improvement programs. These efforts focus on aggregate statewide metrics that may not reveal detailed insights from individual projects. WisDOT Majors and Mega projects are generally transformative in nature and represent some of the most complex and costly investments in maintaining safe and efficient infrastructure. Having a better understanding of project-specific post-construction outcomes would improve planning and design decisions for future projects, build confidence that proposed benefits of significant projects are being realized, and provide accountability.
