Abstract

The number of demolition work is rapidly increasing because the middle- and high-rised buildings constructed over the rapid industrialization and urbanization have been deteriorated in social and structural aspects. However, theoretical approaches or studies related to the demolition cost prediction are still insufficient. Thus, this study derived and analyzed important factors affecting the fluctuation of the building demolition costs. 14 factors was derived through literature reviews and experts' interview, and the importance of each factor was analyzed to the each work(temporary work, structure demolition, and waste disposal) and the entire demolition work by using descriptive analysis. The survey results showed that the demolition costs was greatly influenced by environmental properties of the site. The results of this study can be used as a basis for estimating the approximate cost of the demolition work.

급속한 산업화와 도시화를 거치면서 대량으로 건설된 중 고층 건물이 사회적, 구조적으로 노후됨에 따라 해체공사가 대거 증가하고 있다. 그러나 해체공사비 예측을 위한 이론적 접근이나 관련 연구는 미흡한 실정이다. 이러한 배경에서 본 연구는 건축물 해체공사비 변동에 영향을 미치는 중요 요인을 도출하고 분석하고자 하였다. 이를 위해 먼저 문헌고찰과 전문가 그룹의 자문을 바탕으로 14개의 영향요인을 도출하였으며, 설문조사를 실시하여 가설공사, 구조물 해체, 폐기물처리, 전체공정별 중요도를 파악하고 분석하였다. 그 결과, 해체공사비의 변동은 해체현장의 환경적 요인들에 의한 영향이 큰 것으로 분석되었다. 본 연구의 결과는 해체공사 발주단계에서 개략공사비 추정을 위한 기초자료로 활용될 수 있을 것이다.
