State Transportation Agencies (STAs) frequently encounter challenges leading to cost overruns and schedule delays occurring during the execution process of highway projects. Scope changes are one of the major root causes of these cost increases and schedule delays. Therefore, the aim of this study is to evaluate the current practices of the project scoping process (PSP) in the highway industry and develop a multi-level project scoping model for transportation infrastructure projects. For this purpose, the research team used resources from existing literature in order to assess current industry practices for the development of three alternative scoping processes. Integrated Definition (IDEF) modeling technique was used to develop these scoping processes. After analyzing the three developed frameworks, the team selected the one that best represented key scoping activities and had the highest level of detail for further development. The proposed scoping model consists of four levels with three main functions of selecting the project, analyzing the project, and advancing the preferred alternative. The four stated levels include 20 activities and 84 sub-activities as well. Eventually, subject matter experts (SMEs) who worked in different STAs validated the developed PSP framework. Development of a project scoping process model leads to the adoption of appropriate best practices and strategies, which reduce costly scope changes and prevent unnecessary delays for infrastructure projects.
