Abstract

Various defects that occur in the maintenance stage are connected to all kinds of wasted resources and economic losses as additional investments are made. Residents are harmed temporally, materially, and psychologically, and businesses suffer not only monetary losses but also reduced credit ratings. The aim of this study was to increase the efficiency of quality management and minimize defect disputes by estimating the importance of the defect type considering the defect frequency and severity in apartment buildings. For this, 7,548 defect items for 48 apartment buildings were examined. The analysis confirmed that defects are concentrated on RC, finishing and MEP work. In addition, defects with high importance are identified as broken, incorrect installation, missing tasks, and water problems. In addition, the exterior wall/roof, the Internal wall, ceiling, and floor, which are constructed in the field, are more important than the furniture and MEP equipment installed in the field.

공동주택 하자는 추가적으로 투입되는 각종 자원의 낭비, 경제적 비용손실로 연결되며, 입주자들에게는 시간적, 물질적, 정신적 피해를 주고, 기업에게는 금전적인 손실뿐만 아니라 기업 신용도를 추락하는 문제를 발생시킨다. 이러한 관점에서 본 연구에서는 다수의 하자분쟁 사례를 활용하여 공동주택 공종/하자유형/부위에 대하여 하자 빈도 및 심각도를 고려한 중요도를 산출하여 공동주택 하자관리 효율성을 제고하고, 하자분쟁을 최소화하는데 기여하고자 한다. 이를 위하여 본 논문에서는 공동주택 하자분쟁사례 48건, 약 7,548개의 하자항목 자료를 토대로 분석을 실시하였다. 분석 결과를 정리하면, 하자가 주로 발생하는 공종은 RC, 마감, MEP 공종이며, 중요도가 높은 하자유형은 균열, 누수, 오시공, 미시공 등인 것으로 확인되었다. 또한 하자부위의 경우 상대적으로 현장 설치 중심의 가구, 설비기기보다 현장 시공 중심의 외벽, 내벽, 내부 천장 및 바닥이 하자 중요도가 높은 것으로 확인되었다. 이에 따라 기본적으로 생애주기 각 단계별 품질관리를 철저히 할 필요도 있지만, 내부공간을 구성하는 부위의 경우, Pre-fabrication에 대한 활용성을 높이는 것을 고려할 필요가 있다.
