Abstract
This study is aimed at offering basic data for enhancing the organizational structure and productivity of on-site construction management (CM) employees. To accomplish the objective, the organizational operation system and employee evaluation of domestic CM companies were analyzed by site scale to promote efficient operation. The findings are as follows. First, in terms of CM workforce, the employees handling architecture, electricity, and machines represented the highest proportion. As for qualification, top engineers were dispatched to both large-scale and small-scale CM sites more than any other employee. Second, the results on CM organizational productivity are as follows. The per capita sales increased as the service payment increased. In terms of scale, the site worth less than a billion won had per capita sales of 76 million won, about 5 times less than the site worth 5 billion won or more whose per capita sales were 371 million won. The monthly per capita sales also increased as the service payment increased. However, the difference was minimal, about a half of the difference in per capita sales. These findings would be useful for companies that have no systematic criteria for CM organization selection and evaluation.
