건축공사에서 지하공사는 전체 주 공정으로 전체공기와 공사비에서 큰 부분을 차지하고 있으며, 특히 도심지의 경우 해마다 규모가 증가하고 있다. 현재 현장에서 시공하는 지하옹벽은 많은 기능 인력이 필요하고, 공사기간 측면에서도 불리한 유로폼+솔져시스템에 의하여 공사가 진행되고 있다. 이를 보완하기위해 신소재 거푸집과 신공법이 개발되고 있으며, 공사기간 단축과 원가 절감이 요구되고 있는 실정이다. 따라서 본 연구에서는 건축공사 현장에서 가장 많이 사용되는 유로폼+솔져시스템과 토목공사 현장에서 사용된 무지주 지하옹벽 거푸집 공법을 경제성 측면에서 비교해 보고자 하였다. 연구 결과, 유로폼+솔져시스템이 재료비 측면에서는 유리하나, 노무비 측면에서는 불리한 것으로 나타났다. 하지만 무지주 거푸집의 현장 적용 활성화를 위해서는 재료비의 절감을 위한 추가적인 연구가 필요할 것으로 사료된다.

Considering the entire critical path, underground works in construction projects occupy a large part of the total construction period, as well as a large part of the construction costs. Particularly in the downtown area, the scale of underground work has been increasing every year. Currently, underground retaining walls, which are built at construction sites, require many skilled workers, and the works are being undertaken by means of the Euroform+Soldier system, which is quite disadvantageous in terms of the construction period. In order to complement this, forms made of new materials and new construction methods have been developed. Now more than eyer, the shortening of construction periods and the reduction of construction costs is required. Considering this, in this study, the researcher has tried to compare the Euroform+Soldier system, which has been the system most frequently used on construction sites, to the non-supporting form system, which has been used on the sites of civil engineering work. The results of the research revealed that although the Euroform+Soldier system was advantageous from the perspective of material costs, it was disadvantageous in terms of labor costs. It is thought that an additional study on a method for reducing the material costs is required, so as to revitalize the application of non-supporting forms to the construction site.
