Abstract

Public-private partnerships (P3s) projects have gained widespread popularity in both developed and developing countries due to their ability to access new financing sources and shift specific project risks to the private sector. P3s has been an active area of research with a particular focus on the concept of Critical Success Factors (CSF). The growing interest and the diverse outcomes associated with P3s emphasize the need for a thorough investigation into the factors that contribute to successful P3 projects. This study focused on identifying the CSFs for P3 highway and building projects towards project objectives of achieving cost efficiency and schedule advantage using literature reviews and questionnaire survey. Additionally, the study aimed to conduct an empirical analysis by comparing cost and schedule performances of P3 projects with design-build (DB) and design-bid-build (DBB) highway and building projects. To collect data regarding critical success factors relevant to real projects in the United States, the research has employed a questionnaire survey. This survey was distributed to participants involved in P3 highway and building projects who provided ratings for the identified CSFs relevant to their respective projects. Furthermore, the study extended its data collection efforts to include DB and DBB highway and building projects of similar size and scope, to facilitate a comparative analysis enabling an assessment of cost and schedule effectiveness of these three project delivery methods. The study concluded that the P3 highway projects in the United States have better cost performance compared to DB and DBB projects. Similarly, P3 building projects exhibit better cost and schedule performance in comparison to DB and DBB projects while no statistically significant difference was found in schedule performances between P3 and DB projects. It is hoped that the research findings will assist the public owners to ensure the success of their future P3 endeavors, particularly in terms of cost and schedule performances. The study outcomes can hold potential in public and private sectors by providing insights into how specific critical factors can be applied to enhance the execution of P3 method in both highway and building construction projects.
