Abstract

Fatal accidents in the construction industry account for a higher proportion than other industries, and in particular, the collapse accident of formwork is likely to lead to a serious accident like death. This study aim to derive the importance ranking of formwork collapse factors using AHP technique for preventing fatal accident. The AHP survey was conducted on field construction engineers, construction project managers, safety managers, and formwork specialist foreman with 10 years on site experience. The results of AHP analysis is that the most importance factor of formwork collapse accident is 'non-compliance with the formwork shoring assembly drawing'. Next it is important in the order of 'poor installation of formwork shoring and accessories', 'formwork shoring is not installed vertically', 'non-compliance with the concrete curing period of the formwork shoring', 'safety supervisor not designated and negligent'. It is necessary to preferentially and intensively manage the high importance factors presented as a result of this research for reducing formwork collapse accident. In addition, it will contribute to reducing construction safety accidents if the factors of the formwork collapse accident suggested in this research are included in the formwork inspection check list and checked step by step in formwork construction.

건축공사 재해 중 거푸집공사 비중이 매우 크다. 거푸집 공사 재해 예방을 위해 관련 연구가 장기간 걸쳐 진행되고 있지만 지속적인 노력에도 불구하고 재해가 줄지 않고 있다. 따라서 본 연구에서는 AHP 기법을 활용하여 거푸집 붕괴사고 요인별 중요도 분석을 하고 관리할 우선 요소를 정하고자 한다. 분석 결과 시공요인, 관리요인, 설계요인 순으로 가중치가 높게 나타났다. 따라서 시공요인을 우선적으로 관리하면 거푸집 붕괴 재해를 예방할 수 있을 것으로 사료된다.
