Abstract

In recent years, the proportion of medium and small-sized apartments within the housing market has seen a noticeable increase, alongside a corresponding rise in disputes related to construction defects. Such disputes are most prevalent in the finishing works phase of construction, which not only are frequent in occurrence but also impose significant repair costs. Furthermore, there is a noticeable scarcity of research focused on the quality management of finishing work defects prior to the completion of construction. Addressing this issue necessitates a methodology capable of preemptively identifying defects by analyzing their frequency and associated costs across various defect types. Consequently, the aim of this study is to propose a risk assessment methodology by conducting an analysis of defect cases across 3,299 apartment units, considering aspects such as frequency and severity. The outcomes of this research endeavor are expected to offer practical management strategies to enhance the quality of apartment finishing works and serve as an academic foundation for the enhancement of construction management systems pertaining to apartment finishing works.

최근 공동주택의 주거 비율이 높아짐에 따라 이에 따른 하자분쟁이 증가하고 있는 추세이다. 이러한 하자들 중에서도 마감공사는 발생빈도가 가장 높으며 이를 보수하기 위한 막대한 비용이 발생한다. 그러므로 이러한 문제를 해결하기 위해 하자 발생빈도 및 보수비용을 활용한 하자위험도를 미리 도출하여 하자순위별로 사전에 예방할 수 있는 관리기법의 개발이 필요하다. 따라서 본 연구에서는 공동주택 마감공사의 하자유형별 분석 및 위험성 평가 방법을 도출하는 것을 목적으로 한다. 이를 위해, 최근 준공된 마감공사 하자사례를 조사하여 하자위험 우선순위를 도출하고 하자관리를 위한 위험성 평가방법을 제시하였다. 본 연구의 결과는 공동주택 마감공사의 품질향상을 위한 관리제도 개선의 근거자료로 활용될 것이다.
