Cracks, which account for the largest proportion of defect lawsuits in apartment buildings, are not clear on the criteria for defect determination, so judgments about defects are mixed. Interlayer cracks, which account for most of the crack defect judgment amount, tend to be judged as defects regardless of the crack width or condition, and repair methods are mostly set uniformly. This starts from the problem that the standards of the Ministry of Land, Infrastructure and Transport and the Construction Appraisal Practice, which the courts use as standards, do not match. It is necessary to establish a defect determination standard that can be applied to all stakeholders through the amendment of laws and the revision of the Court Appraisal Practice. In addition, it is necessary to apply the crack repair method according to the width and condition of the interlayer crack. If the defect determination and the application of the repair method for cracks are rationalized, it could serve as an opportunity to change the current trend of defect disputes that rely only on litigation.

하자 여부를 판정할 정부의 매뉴얼이 신설되고 분쟁조정 실무를 전담처리할 사무국도 출범하여, 진단기관별로 제각각인 공동주택의 하자 판정이 공정해지고 분쟁조정 속도도 빨라질 전망이다. 국토해양부는 지난 10월 18일 정창수 제1차관과 하자심사분쟁조정위원, 사무국 관계자 등이 참석한 가운데 하자분쟁조정위원회 사무국 개소식을 개최하고 본격적인 분쟁조정 업무 추진에 들어갔다. 국토부는 또 객관적이고 실효성 있는 하자분쟁조정을 위해 하자판정 기준 매뉴얼을 마련하고 각계의 의견수렴을 위해 지난 10월 18일 한국과학기술회관에서 전문가와 주택업계, 입주자 등이 참여한 가운데 공청회를 개최했다.

This study aimed to find out the improvement plan through analyzing the perception of the expert group engaged in landscape architectural construction and to focus on analyzing the expert groups' experience on Landscape Construction Defects (LCD), defect liability, warranty period, and implementation of the defect liability. The results are as follows: 1. Regarding the experience on the LCD, landscape construction contractors were an awareness of the LCD issue at a serious level, while public-sector clients recognize moderately the LCD issue; and on the first priority in defect implementation, landscape construction contractors considered repair cost while public-sector clients value the identifying causes of defects. 2. In disagreement on the defect liability, landscape construction contractors attributed it to client's lack of responsibility for maintenance while public-sector clients ascribed it to the absence of dealing a criteria with LCD, and regarding the appropriate defect implementation, public-sector clients preferred the following objective by dealing the criteria with LCD while landscape construction contractors advocates by sharing the responsibilities for dealing with LCD based on the identified causes of construction defects. 3. Regarding the warranty period, the public-sector clients considered the 2-year warranty period as appropriate while landscape construction contractors considered it comparatively long, and concerning the commencement of defect warranty period, the public-sector clients viewed it as it should commence to cover the overall completion of the construction while landscape construction contractors perceived it to start on the completion of each work. 4. As for the improvement of the defect implementation system, public-sector clients considered it necessary to establish the objective dealing the criteria with LCD while landscape construction contractors viewed the legislation of maintenance duty. Also, with regard to the important value in establishing and dealing the criteria with LCD, public-sector clients pointed out the objective of the criteria for determining the defects per work type while landscape construction contractors suggested client (user)'s maintenance duty. Because of research, because the system in dealing with LCD is an absence of LCD management agency and dealing the criteria with LCD, it is needed to establish an LCD management agency and make the system in dealing with LCD.

The purpose of this study was to analyze judicial precedents related on landscape construction defects(JPLCD) and suggested the improvement plan for dealing with it. The results are as the following: 1. Landscape construction defects litigations have been increased so far since 2000 and the duration of original trial was approximately 603 days, while appeal trials took up to 550 days. Therefore, the analysis revealed that settlement of disputes were lengthy and wasteful to consumers and constructors. 2. Judgement's cost accepted by the judge was only 53.6% of appraisal's cost appraised by appraiser, therefore it revealed appraiser overestimated the repair cost of landscape construction defects. 3. According to work classification categorized by Landscape Construction Standard Specification(2008) of the Korean Institute of Landscape Architecture, landscape planting amounted to 75% of JPLCD and plaintiff(consumers)'s prevailing rate of it reached 77% to be a serious burden to constructors. 4. According to JPLCD categorized by the type of dispute, defects caused by consumer's negligence for maintenance amounted to 29% and defendant(constructors)'s prevailing rate of it reached 64% to be the main responsibility of consumers. Further study will be required to make the judge standard of landscape construction defects through legal and technical research.

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 of apartment housing. Accordingly, construction companies and residents have conflicting views on defects in apartment housing. To address this issue, this study aimed to accurately identify the main disputes surrounding defects in multi-family housing complexes or multi-dwelling unit apartment housing 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 an analysis of defects in past court cases, and the differences in perspectives between construction companies 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-family homes was also proposed.

As the domestic housing supply problem has been resolved, the apartment construction market has shifted to a consumer-oriented market that wants high quality, and in particular, expectations in the area of finishing quality have increased. Looking at the status of complaints regarding apartment housing defects supplied by Korea Land and Housing Corporation, tile-related complaints are the type occurring the most frequently. While the Ministry of Land, Infrastructure and Transport(MOLIT) is making an ongoing effort to reduce complaints related to defects, through approaches such as drafting amendments to 「Investigation of defects in apartment houses, calculation of repair costs, and standards for determining defects」, the provision of preventive measures has been insufficient. In addition, by reviewing studies, there has been insufficient research to construct a classification system after deriving the characteristics of each type using the qualitative knowledge of experts, various quantitative indicators, and suggesting measures for reduction according to the causes of each type. Therefore, this study will reflect qualitative indicators to use the AHP analysis that makes it easy to identify the relationship between defects by surveying construction experts. Then, by visualizing the weight of 'Possibility of recurrence after repair,' 'Degree of difficulty in repairing defects' and 'Fault frequency' using a radial graph, we will analyze the characteristics of each type of tile construction defect and establish measures for reduction according to the cause. This will improve the quality of the living environment and contribute to the establishment of a system for smooth defect management and reduction of defects in apartment tile construction.
