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 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.

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.

건설프로젝트는 장기간에 걸친 현장생산방식으로 이루어지며, 대부분의 공종이 야외에서 이루어지는 특징을 가진다. 따라서 공정계획 수립 시 예정공사기간 준수를 위한 방안으로 작업불능일을 산정하여 Activity에 반영하고 있다. 하지만 이러한 작업불능일은 경험과 직관에 의해 일률적으로 일수를 판단하는 것이 대부분이며, 전문가마다 필요한 정보와 업무방식이 각각 상이하여 같은 현장이라도 산정하는 방식이 다르고 그 결과도 차이가 심한 실정이다. 따라서 작업불능일 산정 시 업무정보의 과학적이고 정량적인 이해가 필요하게 되었다. 따라서 본 연구에서는 작업불능일 산정에 필요한 업무정보를 수집, 정리하여 작업불능일 산정 프로세스를 도출 하였으며, 산출된 프로세스를 바탕으로 기초화면을 설계 하였다. 전문가 인터뷰를 통해 검증한 결과, 기존 업무대비 약 69%의 업무시간 단축효과와 92%의 업무정보 매트릭스의 신뢰성을 보였으며 80%의 전문가가 시스템화에 대해 긍정적으로 평가하였다. 본 연구를 통해 작업불능일 산정업무 시 업무이해를 증진시키고 정량적인 업무수행에 따른 효율화를 도모할 수 있을 것으로 보이며 향후 시스템화에 대한 연구가 지속되어야 할 것이다. Construction projects consist of long-term on-site production, and most disciplines are featured by outdoor works. Therefore, when a process plan is established, non-working days are calculated and reflected in a process schedule to comply with the planned construction period. However, necessary information and working methods are different in the course of the work, so the method of calculation varies depending on persons even for the same site, and the result is also very different. Therefore, scientific and quantitative understanding of business information is needed. This study reconstructed non-working day estimation process by collecting and organizing the information necessary for non-working day estimation, and designed the demonstration screen based on the reconstructed process and verified through expert interview at each stage. As a result, it showed about 69% reduction of work time and reliability of 92% work information matrix, and 80% of the experts evaluated the systemization of the relevant work. This study is expected to improve the understanding of work and increase the efficiency of work performance, and the study on systemization in the future should be continued.

These days, interior construction is performed to prevent the deterioration of old building finishings or to make distinctive designs. In case of interior construction, a construction cost is estimated through basic 2D drawings in the design step. Accordingly, an efficient construction plan and direction is established according to budget. In such a case, construction is dependent on 2D drawings. At that time, a risk can occur easily. This study is aimed at reducing the cost and risk of interior construction by implementing 3D drawings with the use of the visual data of 2D drawings. For accurate analysis, 2D drawings were completed, and then 3D interior construction modeling for various buildings was conducted with the 3D modeling software 3D Max. According to the 3D modeling, it reduced the cost and risk more than 2D drawings based design, and influenced the improvement in the understanding of orderers and workers.

Apartment houses are now a popular form of general housing, and the construction techniques and materials quality used to construct apartments are also continuously evolving as if they were representative. However, issues concerning flaws are constantly being reported in the press. This study attempts to analyze the trend of conflicts related to defects and to analyze the types of defects received in the apartment building, to suggest the development of the integrated defect management system, and to develop the construction based on the development of the system.

The management of defects in barracks facilities is carried out in such a way that defects found by the facility's manager are listed and requested to be repaired by the contractor. However, the standards and methods for the inspection of defects in the management of these defects are not specified in detail, so it is difficult to check the defects in detail. In response, the study first analyzed the current status of the number of defects that occurred in 2021 at official residences and barracks of certain units. As a result of the analysis, the number of defects that were not taken care of and that were not taken until the previous month was more than 10 cases on average per month. In order to reduce the number of such defects, major improvements in the field, timing, and safety inspection were found after the inspection of the military's facilities and safety, and the analysis of the manual of maintenance management. In addition, items for improvement of the checklist were derived through an analysis of the repair of defects caused by the unit's official residence and a total of 10 barracks facilities. Based on this, a checklist was proposed to manage defects in barracks facilities through interviews with military facility managers.
