Abstract

The importance of the appropriate use and procurement of Safety and Health Expense has been increasing along with the recent increase of construction projects in height, size and complexity. However, the current standards for deducting the Safety and Health Expense have shown limitations in applying the properties and environment of the construction project due to its Safety and Health Expense Rate's classification method. Therefore, the purpose of this study is to develop a prediction model for the Safety and Health Expense that enables the consideration of different environment and properties of construction projects. The study uses multiple regression analysis to analyze the Safety and Health Expense of Ordinary(A) of less than 0.5 billion WON. The research results have shown that the use of multiple regression analysis reduces the error rate to 4.38% which the current standard calculation method have shown 18.48%. Therefore, the use of the suggested model provides reliable Safety and Health Expense prediction values that considers the properties of the project. It is expected that the results of this study contributes to the effective safety management by providing the appropriate amount of Safety and Health Expense to the project. In this study, only projects of less than 5 billion WON have been considered in the analysis. Therefore, more data is required for future studies to suggest an overall Safety and Health Expense predict ion model that covers the whole construction industry.

최근 건설프로젝트가 고층화, 대형화, 복잡화됨에 따라 적정 수준의 건설업 산업안전보건관리비 확보 및 사용에 대한 중요성이 증가하고 있다. 그러나 현행 건설업 산업안전보건관리비 계상요율은 공사의 종류 및 규모로만 분류하여 일괄적으로 제시되어 있어 각각의 건설프로젝트가 지니고 있는 공사의 환경 및 특성을 반영하지 못한다는 한계점을 지니고 있다. 따라서 본 연구의 목적은 건설업 산업안전보건관리비 산정 시 건설프로젝트별 공사 환경 및 특성을 고려할 수 있도록 하는 건설업 산업안전보건관리비 예측 모델을 개발하는 것이다. 이를 위해 본 연구에서는 일반건설공사(갑) 50억 미만 공사현장에 대해 현장의 여건 및 건설업 산업안전보건관리비의 사용 실태를 조사하고, 이를 대상으로 통계적 기법인 다중회귀분석에 적용하였다. 분석 결과, 예측 모델은 검증군에 대해 기존 요율로써 산정할 때의 오차율(18.48%)보다 낮은 오차율(4.38%)을 보여, 기존의 방식보다 높은 예측정확도를 보이는 것으로 분석되었다. 개발된 예측 모델을 활용할 경우 각 건설프로젝트가 지닌 공사 환경과 특성이 반영된 보다 현실적인 건설업 산업안전보건관리비를 확보할 수 있을 것으로 예상되며, 이러한 적정 수준의 건설업 산업안전보건관리비 확보는 건설프로젝트에 양질의 안전관리를 제공함은 물론, 나아가 건설 안전사고 최소화 및 건설 재해율 감소에 기여할 것으로 기대된다. 본 연구는 건설업 산업안전보건관리비 예측 모델 개발을 위한 초기단계의 연구로 50억 미만의 일반건설공사(갑)으로 범위를 한정하였으나, 향후 추가적인 데이터 수집을 통해 건설업 전반에서 활용 가능한 건설업 산업안전보건관리비 예측 모델이 개발될 필요가 있다.
