밀폐형 돔 구조물의 시공사례분석을 통한 공사관리 개선방안

Abstract

This study, the construction methods and problems were analyzed by construction cases of the closed dome structure. In the construction of the closed dome structure, this study analyzed the effect of learning effect on construction period and labor cost due to repeated work. Then, it suggested the improvement of construction management by integrating analysis contents. The study results are as below. In this study, through the construction case analysis, the learning effect is derived from the repetitive work such as minimization of errors in design drawings, appropriate input of personnel by construction stage, and aggressive input of construction equipment to milestone. According to the learning effect, the construction period was reduced by 25% in the construction site of the same size. Analysis of similar construction cases shows that equipment costs are increased by 45%, but labor costs are reduced by 22%, resulting in a total cost savings of 13.5%. In other words, it was shown that the cost can be reduced by learning effect.
