Abstract

Differences between the client (employer) and contractor in road construction projects, as a significant problem, can substantially impact project efficiency, scheduling, and quality. This research aims to identify, prioritize, and provide practical solutions for managing and reducing these differences. Initially, twenty of the most important factors contributing to disputes were extracted through literature review and interviews with road construction experts. These factors were evaluated and ranked using fuzzy hierarchical analysis, considering criteria such as probability of occurrence, impact on time and cost, repeatability, and complexity of resolution. The findings revealed that delays in completion due to general factors (weight 0.087), unrealistic schedules and inaccurate estimates (weight 0.073), and disputes arising from changes in work and overtime (weight 0.063) ranked first to third. Finally, based on the results obtained, practical and tailored solutions are provided for each of the prioritized conflicts, aiming to focus on the main factors and enhance collaboration and success in road construction projects .
