Recently, global construction companies are turning to PMC, a high value-added business. However, domestic construction engineering companies are still conducting projects focused on detailed design and construction supervision. This study aims to investigate the necessity of introducing PMC by analyzing the cases of completed projects in which PMC was introduced among domestic construction projects. Among the large-scale national projects in Korea, examples of the application of global standard PM include nuclear power plant projects in the 1970s, Gyeongbu High Speed Rail, Incheon International Airport, Incheon Bridge and Yongsan United States Forces Korea Base Relocation Plan (YRP) projects. However, these projects are PMC projects carried out by advanced global companies in Korea. There is an implication in that the necessity of introducing PMC for the successful completion of large-scale national projects was analyzed through the case analysis of these projects.
