Abstract

Selecting an appropriate superstructure construction method is crucial for the success of bridge projects. This study aims to evaluate and prioritize various bridge construction methods using a multi-criteria decision-making approach based on the Analytic Hierarchy Process (AHP). Five key criteria—quality, cost, safety, project duration, and structural form—were identified as the most influential factors in the decision-making process. The statistical population included engineers, contractors, consultants, and supervisors involved in bridge construction projects, from which 68 experts were selected through convenience sampling. Data collection was conducted using both library research and field methods, including interviews and questionnaires. Data analysis was carried out using Expert Choice software. The results indicate that the cable-stayed bridge construction method ranked highest with a priority weight of 0.280, making it the most suitable option for bridge implementation in Iran. Following this, incremental launching, prestressed concrete, precast concrete, span-by-span steel, balanced cantilever steel, and cast-in-place concrete methods were ranked accordingly. Among the criteria, safety was identified as the most significant factor across most construction methods, except for the prestressed concrete method, where quality held the highest importance. The findings of this study offer valuable insights for decision-makers in selecting bridge construction methods under various project conditions.
