A study on the weighting of factors for evaluating the potential of subcontractors: A case study of a bridge construction project

Abstract

This study aimed to determine the weight of importance for the factors used in evaluating the potential of subcontractors in bridge construction projects. The research explored the problems and obstacles caused by subcontractors that affect project implementation and linked these issues to an analysis of the key success factors. Data were collected through interviews with four experts in the bridge construction projects, and the Analytic Hierarchy Process (AHP) was applied to identify the relative importance of each factor. The results showed that the most critical factor is human resources, with an average weight of 0.253. The second most important factor is project financial liquidity, with an average weight of 0.196. These are followed by safety and environmental factors (0.160), project management (0.159), equipment and machinery (0.089), procurement of materials (0.074), and finally, risk management, which has the lowest average weight of 0.070. The determination of factor weights from this study enables project managers to accurately prioritize evaluation criteria and improve subcontractor potential in bridge construction projects in a way that aligns with the project's specific needs.
