Abstract

Due to the significance of sustainability in the construction industry, it is essential to establish a precise mechanism for evaluating the sustainability performance of contractors, who are a crucial component in project execution.  Analyzing contractors' sustainability performance indicators is a crucial step in identifying the contractor most dedicated to sustainability standards.  This study seeks to identify and comprehend the principal sustainability performance metrics of contractors in Iraq, considering the direct influence of their projects on community development and welfare.  According Based on previous studies, sustainability indicators were gathered and categorized into three categories (environmental, social, and economic), resulting in a total of 127 indicators.  A questionnaire was subsequently developed and disseminated to a selection of engineers and sustainability experts, yielding (104) responses for study.  The statistical software (SPSS-V26) was employed to analyzed the results and establish priorities. The principle of the relative importance index was also applied, and indicators with an importance greater than or equal to 0.70 were selected in order to reduce the number of indicators and select the most important ones. 64 indicators were obtained, which constitute the basis for selecting sustainable contractors.
