Challenges and Research Directions in Multi-Project, Multi-Actor Infrastructure Construction Management

Infrastructure construction programs are often highly complex due to the involvement of multiple projects and actors.The presence of multiple projects introduces interdependencies that necessitate the coordination of schedules, resources, and priorities, as well as the implementation of risk management strategies.Simultaneously, the involvement of multiple actors gives rise to power dynamics, challenges in communication and engagement, and competing interests that must be effectively managed.A systematic literature review is conducted to explore how the challenges associated with managing multiple projects and multiple actors are addressed within the field of infrastructure construction management.Key themes, strengths, and limitations within the literature are identified.Based on this analysis, critical research gaps are outlined, and potential directions for future research are proposed.The main findings highlight six key gaps that may serve as a foundation for future investigations aimed at enhancing the management of infrastructure construction programs.
