Abstract

Selecting an appropriate formwork to fit the construction of a high-rise building is an important factor that can influence the success or failure of a construction. Currently, however, the reality is that in domestic high-rise building construction, the selection of an appropriate formwork with consideration of the characteristics of the formwork has not been done in a reasonable manner. To select formwork in a systematic and reasonable fashion, comprehensive consideration is required that must not only include the aspect of construction costs, but also air, quality, safety, and environmental issues. Therefore, this study aims to rationalize the selection process of formwork by applying the scientific method of Analytic Hierarchy Process (AHP) to the selection process of formwork, in terms of construction costs, quality and safety. To do this, the researcher investigated the current status of formwork being used in high-rise residential building construction. Then, based on the results of this investigation, the researcher selected an alternative for the formwork, and taking construction experts as the subjects of this study, conducted a survey on the applicability of the formwork as well as the priority of management thereof when selecting formwork. It is judged that the results of this research will contribute a more scientific and reasonable decision-making process than the existing non-scientific method in selecting formwork for high-rise residential building construction.

고층 주거건축물 공사에서 적합한 거푸집의 선정 여부는 프로젝트의 성패를 좌우하는 중요한 요인이다. 그러나 현재 국내 고층 공사는 거푸집별 특성을 고려한 적합한 거푸집 선정이 이루어지지 못하는 실정이다. 합리적이고 체계적인 거푸집 선정을 위해서는 공사비뿐 아니라 공기, 품질, 안전 등을 포함한 종합적인 고려가 요구된다. 따라서 본 연구에서는 공사비, 공기, 품질, 안전측면에서 거푸집 선정에 대해 계층분석적 의사결정(AHP)의 과학적 방법론을 제시하여 거푸집 선정 프로세스를 과학적 방법으로 합리화 하고자 한다. 이를 위해 국내 고층 주거건축물에 사용된 거푸집 현황을 조사 후 이를 토대로 거푸집 대안을 선정하고 공사 전문가들을 대상으로 거푸집 선정 시 관리 우선순위 및 거푸집 적용성에 대한 설문조사를 실시하였다. 본 연구 결과는 고층 주거건축물 거푸집 선정 시 기존의 비과학적인 방법을 보다 과학적이며 합리적인 의사결정에 기여할 것으로 판단된다.
