건설사와 입주민의 공동주택 하자분쟁 쟁점 및 개선 방안

방홍순,김옥규 한국건축시공학회 2022 한국건축시공학회지 Vol.22 No.1

입주민은 육안으로 구별이 되는 하자를 중심적으로 보며, 건설사는 공동 주택의 구조적, 기능적 문제에 영향이 가는 하자를 중심적으로 본다. 그에 따라, 건설사와 입주민은 공동주택의 하자를 기준으로 서로 다른 관점을 가지고 있다. 이를 해결하기 위해 본 연구에서는 서로 다른 하자의 관점차이로 인하여 발생하는 공동주택 하자분쟁의 쟁점과 개선 방안을 목표로 진행하였다. 먼저, 국토교통부와 법원의 서로 다른 하자판정기준 및 보수기준을 분석하였다. 과거 청구소송 하자판결 사례분석을 통하여 문제점을 도출 하였으며, 여러 건설사의 하자 데이터를 기반으로 건설사와 입주민의 관점차이를 도출 하였다. 이를 해결하기 위해 공동주택 하자 데이터베이스의 개선방안을 제안하였다. In the area of construction defects, residents have a tendency to focus on visually identifiable defects,while construction companies focus on defects that affect the structural and functional integrity ofapartment housing. Accordingly, construction companies and residents have conflicting views ondefects in apartment housing. To address this issue, this study aimed to accurately identify the maindisputes surrounding defects in multi-family housing complexes or multi-dwelling unit apartmenthousing caused by such sharply different perspectives and suggest improvement measures. First,standards to determine different defects and remuneration standards between the Ministry of Land,Infrastructure and Transport and the court were analyzed. Then, problems were derived through ananalysis of defects in past court cases, and the differences in perspectives between constructioncompanies and residents were identified based on defect data from various construction companies. To tackle these issues, a classification measure for establishing a defect database for multi-familyhomes was also proposed.

There are secondary defects in apartment buildings that are not directly produced from construction errors, but are derived from other types of defects. To improve the quality of the type of construction that causes these secondary defects, it is important to define and manage them by analyzing data regarding defects in apartment buildings. This study analyzed approximately 1.33 million cases that finished defect repairs in 2019 then defined the frequency and repair costs of fundamental and secondary defects. This analysis revealed that secondary defects had accounted for 3.83% of the entire defect frequency and made up 6.08% of the repair costs. Using text mining techniques, this analysis presented the types of construction that had caused secondary defects in apartment buildings in the order of frequency and average similarity to reduce such secondary defects. According to the similarity analysis of the types of construction, wallpaper work topped the frequency order with 68,060 cases, which took up 38.36%, and its similarity was 0.615 on average. Furthermore, with 4,518 cases, electricity work was first in the average frequency at 2.54% and its average similarity was 0.955. To present these results as a whole, the word cloud technique was used. 공동주택 하자의 일부는 해당공종 자체에서 발생한 하자가 아닌 다른 하자에 유발되어 발생한 2차 하자가 존재한다. 이를 해결하기 위해서는 공동주택 하자 데이터 분석을 통하여 2차 하자를 유발하는 공종을 도출하여 관리하는 것은 중요하다. 이에 본 연구에서는 2019년에 하자보수가 완료된 약 133만 건의 데이터 분석을 통하여, 1차 하자와 2차 하자 빈도 및 보수비용을 도출하였다. 2차 하자는 전체 하자 중 3.83%의 빈도를 가지고 있었으며, 6.08%의 보수비용을 차지하고 있었다. 이를 저감하기 위해 텍스트 마이닝 기법을 분석하여 공동주택에서 발생하는 2차 하자의 유발 공종을 개수 순서와 유사도 평균 순서를 도출하였다. 유발공종 유사도 분석 결과, 개수 순번으로 도배공사(68,060건, 38.36%)로 가장 높았으며, 유사도 평균 0.615로 도출되었다. 평균 순번으로 일반전기(4,518건, 2.54%)로 가장 높았으며, 유사도 평균 0.955로 도출되었다. 이를 전체적으로 표현하기 위해 워드 클라우드 시각화 기법을 통하여 도출하였다.

Recent rise in the supply rate of new public apartment houses leads to an increasement in disputes regarding the construction quality of the apartments between the residents and the construction companies. According to the dispute cases filed for claiming the collective defect repair fees, inter-layer concrete joints turned out to be the most frequently disputed item. For this reason, this study selects the inter-layer concrete joints to further analyze the primary causes and details of each dispute case. From the results of this study, three primary causes of the disputes are found, which are 1) the absence of standard specifications for construction quality control and management after construction; 2) the absence of established standards for repair when construction defects are found; and 3) the fact that the court grants generous compensation for disputes concerning the apartment houses. In order to prevent construction defects in inter-layer concrete joints, this study provides three suggestions including 1) the current standard specifications for inter-layer concrete joints should be further specified by the Ministry of Land, Infrastructure and Transport; 2) a construction defect should be judged according to the compliance to the standard specifications; and 3) a clear and institutional protocol needs to be established for defect repair in cases that new public apartment houses have been judged to have defects. 신축 공동주택 보급률이 상승하면서 입주민 개인별 자산의 관리적 측면과 함께 품질에 관한 관심이 높아져 공동주택 품질과 관련된 분쟁이 급격하게 증가되고 있는 실정이다. 이에 본 연구에서는 분쟁을 저감할 목적으로 관리주체가 제소하는 집단하자보수비 청구 소송을 확인하여 가장 빈번하게 분쟁이 발생된 콘크리트의 층간이음부와 관련하여 각 사건별로 층간이음부가 차지하는 비중과 쟁점을 분석하였다. 그 결과 분쟁 발생의 원인에는 첫째, 표준시방서가 부재한 점, 둘째, 보수공법에 대한 표준이 없는 점, 셋째, 공동주택의 공통적인 사항이나 법원에서는 이를 관대한 개념에서 배상 범위를 인정하고 있는 점에 있음이 확인되었다. 이에, 하자예방을 위해서는 첫째, 층간이음부 시공에 대한 국토교통부의 표준시방서가 개정되어야하고, 둘째, 표준시방서 이행 여부에 따라 하자판정이 진행되어야 하며, 셋째, 하자로 판정 시 명확한 하자보수공법이 적용될 수 있는 제도개선이 필요한 부분임을 확인할 수 있었다.

In today`s builders PRM(Project Risk Management) for Risk Management to fill out the competitive advantage, by and return it safe and take. But PRM has different standards for each construction company and can also see that even the list. In this study, consideration existing research through PRM by developing a list of check list to proceed to the basic research to help. In this study, PRM by creating a basis of the check list disclosed to the frame of reference. The results of this study by PRM of the check list for field application management system to provide a basis to build.

It was established in August 2016 for the development of the multi-family housing management system as the development of the construction project led to the expansion, complexity, and cutting-edge of multi-family housing. At this time, many construction companies have discovered new kinds of defects. This was analyzed as a ’secondary defect’ derived from the first defect. Due to the occurrence of secondary defects, construction companies are experiencing unpredictable risks. In this study, the construction and repair costs incurred to reduce secondary defects were analyzed. Secondary defects occurred in most finishing industries based on the frequency of defects. In addition, after comparing the frequency of occurrence and the ratio of maintenance costs of secondary defects, the differences were analyzed.

In response to improper apartment housing maintenance practices, residents can file defect complaints or defect dispute litigations against construction companies. Legal arguments can then be made to address conflicting claims regarding housing and maintenance standards along with repair methods. A considerable amount of money and time are typically spent in these legal matters. To address these problems, conflicting claims and other controversial issues must first be resolved before a defect complaint or defect dispute litigation is issued. In this study, 61 court rulings were examined to analyze the controversies related to apartment housing construction defects. Keywords were derived from these cases using a Python program. The derived keywords were classified by work type, location, cause, and type. The main issues related to work type in housing defect court rulings were tiles, fire doors, paint, trees, and facilities. The data related to these items were compared with defect repair data. Analysis of the court cases of main work types and defect repair data revealed that various construction types such as tiles, wallpaper, equipment, and furniture overlapped. Our analysis revealed that if the derived work types are systematically managed, defect disputes and defect filings could be reduced.
