This study aims to determine the competence of project managers that has the most significant influence on the success of a construction project. The data used were questionnaires distributed to 43 respondents employed at contractor companies located in Aceh Province, Indonesia. The samples were selected using Stovin’s formula; data were analyzed using descriptive statistical methods. The results of the study showed that of ten project managers’ competence factors, the top five rankings were obtained by knowledge factor (X1) with a mean value of 4.773, problem-solving (X8) with a mean value of 4.659, technical skills (X5) with a mean value of 4.587, general skills factor (X2) with a mean value of 4.531, and attitude and behavior factor (X3) with a mean value of 4.521. The findings show that the knowledge factor was dominant among all project manager competencies necessary to implement construction projects in Aceh Province. This shows that the knowledge possessed by a project manager significantly affects the successful implementation of such projects.
