Comparison of Efficiency and Satisfaction Level on Different Construction Management Methods for Public Construction Projects in Korea

Selecting appropriate construction management method in construction projects based on owner’s project management capacity can be a make-or-break element. Given the accelerated change in the construction environment, the need for an efficient project management of public construction projects is ever more important, as is the need to select an appropriate construction management method. However, most public project owners find it difficult to select construction management method that perfectly coincides with their capacities or project characteristics since they lack information on the efficiencies of various construction management methods. Under this context, construction management method is usually selected for the sake of convenience or to comply with regulatory requirements. As such, this study aims to provide a basis for project owners to select the most appropriate construction management methods for the projects concerned by analyzing the efficiency of various methods currently applied to domestic public construction projects and also by comparing and analyzing the degree of satisfaction of project participants under each construction management method. In terms of allocated manpower and costs, the inspection supervision method and the construction supervision method incurred additional costs of 42% and 52%, respectively, compared to the direct supervision method. In addition, as for time spent processing tasks, other supervision methods took more time than that of the direct supervision method leading to the conclusion that the direct supervision method appeared to be the most efficient construction management method.
