Abstract

To prevent incident of demolition work the Building Management Act was implemented to manage demolition work. According to this law, buildings with the scale upper than 500㎡ of floor area are classified as permission to conduct the demolition work, however it may be hard to perform safety management at demolition work. In addition, the risk level of demolition work is varied with related to the structure type. So, the purpose of this study is to suggest the improvements of criteria on demolition work considering building structure types including small-scale structures such as masonry, wooden, and other structure. The research process was conducted by three steps. (I) Application of Building Management Act; (II) Analysis of demolition work by structure types; and (III) Subdivision of permission targets by building structure types. The result of this study, permission ratio was only 10% for total demolition work and 2.43% for masonry. Because the masonry, wooden, and other structure types are concentrated on a floor area of small-scale, the separate criteria of demolition work is need to prevent the accident and fatal incident. Through the results, the decision maker can be utilized (1) For the special building structure types, the criteria of enhanced safety management are applied by referring to the overseas law ; and (2) The demolition work can be considered by the criteria of separate permission in terms of structure types.

해체공사의 수요증가와 사고 위험성을 고려하여 정부는 20년 건축물관리법을 시행해 해체공사의 안전관리를 개선하고자 하였다. 그러나 건축물관리법 제 30조 건축물의 해체 허가에 따른 기준은 일률적이기 때문에 규모에 따른 허가대상 건축물의 구분은 불합리할 수 있다. 또한, 해체공사는 건축물의 구조 유형에 따라 공사 난이도 및 발생 재해의 형태가 달라질 수 있기 때문에 본 연구는 건축물관리법상 신고대상에 속하는 조적조 등의 소규모 건축물의 구조 유형을 고려한 해체공사 안전관리 개선 방안을 제시하고자 한다. 본 연구의 순서는 (I) 건축물관리법 기준; (II) 건축물의 구조 유형에 따른 해체공사 분석; (III) 해체공사 허가대상 세분화 순으로 진행되었다. 연구 결과 건축물관리법상 허가대상은 과거 해체공사 실적의 10% 정도, 조적조는 2.43%에 불과하였다. 허가대상 기준을 세분화한 결과 조적조의 경우 연면적 100㎡이하일 때 허가 및 신고대상의 수가 유사해짐을 확인하였다. 이를 통해 이해관계자는 1) 해외와 같이 규모에 관계없이 특수구조 건축물에 강화된 안전관리 기준을 적용하거나, 2) 건축물의 구조 유형에 따라 해체공사 허가 대상 기준을 세분화하는 방식 등을 활용한 해체공사 안전관리를 개선할 수 있다.
