Civil projects play a critical role in shaping urban landscapes over time, serving as visible and enduring social structures. Given their public visibility, meticulous attention to planning and design stages is crucial. Collaboration among project stakeholders is a primary driver of success. Regular progress review meetings are essential, not only to monitor advancement but also to implement timely corrective and preventive measures. Continuous updates to project plans enhance the likelihood of successful completion. Supervision by specialized engineers ensures the safety and quality of constructed structures. This study employs the Analytic Hierarchy Process (AHP) to evaluate the interactive dynamics between consulting engineers and contractors, based on inputs from 217 experts involved in five urban projects in Mashhad, Iran. Pairwise comparison questionnaires were used for data collection, and analyses were conducted using ExpertChoice and SPSS software. The findings identified five main criteria (bid documents, consultant-contractor contracts, consultant requirements, contractor performance, and environmental conditions), along with 21 sub-criteria. Among these, bid documents were deemed the most influential, with a 53.7% weight, underscoring their significance in shaping consultantcontractor interactions. Contracts ranked second at 23.2%, emphasizing the economic and unilateral perspectives often prevalent in project execution. Environmental conditions, with a minimal 3.6% influence, were the least impactful, as they are typically integrated into contractors' operational designs. Overall, the study highlights the pivotal role of enhancing consultantcontractor collaboration in achieving project success.
