This research has explored the potential of segmentation and segmented contracting as a solution for managing the complexities of infrastructure projects in the Netherlands. As the country's civil infrastructure ages, innovative approaches are required to address the extensive challenges of renewal and renovation that lie ahead. This study has examined the benefits, challenges, and key considerations of segmented contracting, providing a comprehensive understanding for clients and contractors. The research has begun by reviewing various project delivery methods, including traditional, integrated, and co-contracting approaches, to establish a theoretical foundation. It has then analysed how segmentation is applied in current and recent projects, identifying its impact on project complexity and potential solutions. A segmentation framework has been developed to guide the application of segmented contracting. The framework demonstrates the impact of horizontal and vertical segmentation on project complexity elements. Additionally, a typology of segmented project delivery methods has been introduced, categorising approaches such as the segmented traditional project delivery method, the segmented integrated project delivery method, the segmented design team (2.0) project delivery method, and the segmented two-phase project delivery method. Expert insights have been incorporated to validate the findings and provide strategic approaches for effective implementation of segmented contracting. Segmentation, segmented project delivery methods, and segmented contracting offer several solutions to address complexity elements in complex infrastructure projects. By breaking down projects into smaller, manageable segments, clients and contractors can allocate resources and expertise more effectively, tailor risk management strategies, and maintain better control over budgets and schedules. This approach facilitates specialised focus on specific tasks, enhances project manageability, and improves the predictability of project outcomes. However, segmentation also introduces significant challenges, requiring robust coordination, communication, and integration efforts. Without these, projects may face inefficiencies, increased risks, and potential delays. Ultimately, this research has aimed to enhance industry practices, improve market competition, and support the civil engineering sector in addressing the significant infrastructure renewal and renovation challenges ahead. The findings have offered both practical and theoretical insights, promoting better management and fostering a more resilient and adaptive built environment.
