Abstract

The form-work operation of concrete structures is a major element determining the period and cost of construction projects. However, the selection of the appropriate form-work system is dependent on the experience of the site personnel only. In this paper, existing methods (Aluminum form, Sky deck) and new slab form-work methods (AFB: Aluminum panel Form with dropping Beam) were selected. Each method was estimated by means of Delphi techniques based on the qualitative analysis data. This paper suggests an evaluation methodology of slab form-work application in construction sites by calculating qualitative evaluation scores. The methodology finding quantified scores of qualitative criteria can be available to be applied to other construction operation evaluation methods.

콘크리트 구조물의 골조공사에서의 주요 공정 중 하나인 거푸집 공사는 전체 건축공사의 공사기간 및 공사비 측면에서 상당 부분을 차지하고 있다. 하지만 공사현장의 조건을 고려한 거푸집의 적정시스템 선정은 현재까지 현장실무자의 경험에만 의존하고 있는 실정이다. 본 논문에서는 거푸집 공법 선정 요인에 대한 정량화된 분석을 바탕으로 슬래브 거푸집 중 신공법과 기존 공법을 선정하여 각 공법의 성능을 정량화된 분석데이터를 바탕으로 평가했다. 이를 통하여 각 공법들의 정성적 항목에 대한 정량화된 평가점수를 산출하여 슬래브 거푸집의 현장 적용성에 대한 평가 방안을 제시하였다. 따라서 본 논문에서 사용된 델파이 기법의 방법론은 다른 공법들의 선정, 평가에도 사용될 것이라 사료된다.
