Evaluation Of Contractor Selection Criteria Using The Analytical Hierarchy Process (AHP) Method

Abstract

The selection of contractors in public infrastructure projects plays a crucial role in determining project success, particularly in complex and high-risk projects such as breakwater construction in coastal areas. This study aims to identify relevant criteria and establish the priority order of these criteria in the contractor selection process using the Analytical Hierarchy Process (AHP) method. A quantitative approach was applied, involving nine expert respondents consisting of government officials, consultants, and project executors selected through purposive sampling. Data were collected through expert interviews, literature review, and pairwise comparison questionnaires, then analyzed using the AHP method by calculating weights, eigenvectors, and the consistency ratio (CR). The results indicate four main relevant criteria: technical capability, managerial capability, financial capability, and reputation and legality. Among these, technical capability has the highest weight of 40.4%, followed by managerial capability (38.1%), financial capability (27.0%), and reputation and legality (24.1%). All assessments are consistent with a CR value of less than 0.1. These findings suggest that contractor selection should not be solely price-oriented but must also consider technical quality and overall organizational capacity to ensure the success of strategic projects in coastal areas.
