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.

최근 주택보급률의 상승과 공동주택 물량의 증가로 인하여 공동주택에 대한 건설기업의 공사 비중이 높아지고 있으며, 공급자 위주에서 수요자 중심으로 분양시장이 변화함에 따라 고객 가치 향상을 위한 고객접점의 하자관리의 중요성이 부각되고 있다. 그러나 국내 공동주택태 하자관리는 하자관리 업무 프로세스 관리 미흡,하자관리 조직의 관리 부족, 하자 정보 피드백 부족, 시공단계의 하자관리를 위한 대비부족으보 동일 하자 요인이 반복적으로 발생하며 고객이 요구하는 품질 및 만족도에 부합하지 못하는 실정이다. 따라서 본 연구의 목적은 이러한 하자관리의 문제점을 해결하고자 하자관리 업무 프로세스 개선 모델을 제시한다. 본 연구에서 제시된 하자관리 업무 프로세스 개선 모델은 하자관리와 품질관리의 통합적 관리를 통하여 정보의 피드백을 실현시키며 하자관리와 품질관리의 업무프로세스를 정렬한다. 또한 부적합 처리 업무를 개선함으로써 하자 관리 관련 업무의 질적 향상을 도모하고 궁극적으로 품질 향상을 통한 건설업체의 고객 만족도 및 이미지 제고에도 크게 기여할수 있을 것으로 기대된다.

Recently, landscaping construction has played a significant role in enhancing the quality of life for citizens by creating and maintaining outdoor spaces. However, landscaping projects vary in material procurement depending on the contracting method, and they also present various challenges in defect occurrence and defect rectification due to their specialized nature. In this study, we classified different types of projects based on material procurement ratios and conducted on-site assessments of defect status by specific processes. We also analyzed the itemization of material ratios and defect rectification costs. The results revealed it was found that projects with a higher proportion of government-provided materials had the poorest defect status in terms of planting works and also incurred the highest defect rectification costs. Moreover, conflicts concerning the responsibility for defects arose. Currently, there are no specific guidelines for setting standards for the proportion of government-provided materials in landscaping construction contracts. Furthermore, there is ambiguity in the management of defect rectification. Therefore, it is necessary to establish a systematic landscaping construction contracting framework by providing institutional guidelines tailored to local governments or the circumstances of contracting entities and to conduct thorough reviews of construction processes.

Construction defect which can causes economic damage such as schedule delay, cost overrun is a considerably important factor in construction industry. In general, a construction defect features a difficulty to find out causes precisely because it occurs when several interrelated causes combine. Yet, studies have tried to understand the interrelationships between factors are limited. In addition, despite of a tremendous amount of construction data, it's not still enough to analyze them, but tends to depend on experience or know-how of practitioners. Thus, it is necessary to identify underlying causes in influential factors by utilizing related data. This paper analyses Interrelationships between causal factors using Association Rule Mining to discover root causes of construction defects. Confidence and Lift that can be used for presenting the interrelationships of the causes were extracted from 1241 cases in 30 projects in Korea. It is expected that this paper allows the construction managers to discover key factors and make right decisions to reduce occurrence of construction defects. Furthermore, analysis of interrelationships can improve understanding of structural patterns of construction defects.

Since 2000s in Korea, apartment building tended to become goods or assets rather than houses. Therefore, conflicts between supplier and consumer were aggravated, and the defect dispute has been increased rapidly. This dispute enlarges to defect lawsuit and it is social and economical matter. The landscape work in apartment building is main work for a resident that appearance and convenient facility which lawn, tree, fountain, chair, playground, and etc. A number of defects surround landscape work are important issue in defect lawsuit, but, a related research is a minority, and a regulation is incomplete. Therefore, this study is basic study for standard of landscape defect type. As case study on defect lawsuit, draw a landscape defect type in apartment building.

There has been a defect dispute of apartment building in Korea. The defect dispute is complicated by main issues and details of dispute. It is yet to be solved. Meanwhile, a judge does not a inspection and analysis, but, related field expert who contracted professional engineer does. As a result, defect consulting report that an important judgment is used in a defect dispute. Therefore, this study does research on structure of defect consulting report. A defect consulting report has same items, irrespective of a defect consultant as a result that check 7 indexes about 10 cases. It has different structure's details depending on each defect consultants. And, it inserts new detail or deletes existing detail, does not show clear distinction.

This study analyzed the actual use of defect deposits for financing long-term expenses (that is, expenses incurred within 4-10 years of building completion) and for financing short-term expenses (that is, expenses incurred within 3 years of building completion). Therefore, 36 cost data on the expenses financed out of defect deposits for apartment complexes were collected from construction companies and analyzed using statistical methods. The findings revealed that 62.6 percent of defect deposits were spent to resolve actual defects, and 37.4 percent were spent resolving resident complaints. Furthermore, these results are valid regardless of the location of the complexes. As such, these results could be of significance when establishing or revising regulations regarding the repair of the long-term defects of apartment complexes.

The purpose of this study is to empirically confirm the effect of the characteristics of construction workers on the occurrence of defects in construction. In this study, the degree of direct construction is measured through the ratio of the direct recruitment and outsourcing manpower of the original contractor, and the effect of this on the occurrence of defects is empirically analyzed using financial data. In addition, it is verified whether the degree of defect occurrence varies depending on the job skill level of the direct hired personnel inputted to the construction. Through this, it will be possible to prepare an argument for revitalizing the direct construction of construction companies and an opportunity to promote it.

Cases of lawsuit and conflict are increasing because of defects in apartments in use after the completion of construction. Further, with changes in the consciousness of residents and in the social environment, many residents are showing interest in defect-related lawsuits. However, the term of warranty liability defined in the current law is not practically appropriate, and the verification of the determination of the term of warranty liability is insufficient. Against this background, this research aims to evaluate the appropriateness of defect repair periods by examining the actual defect condition of the finishing work among the various defects related to apartments. Collected performance data are analyzed by statistical techniques by considering the defect occurrence rate per construction type and the construction year of the finishing work in apartment construction. The analysis results will be used as basic data for evaluating the appropriateness of the standards for the term finishing works warranty liability.
