Recently, quality inspection and defect management have been considered as one of the major issues for increasing customer satisfaction and corporate image in domestic construction industry. However, the quality inspection and defect management have not been performed systematically because of insufficient field managers, the excessive amount of documents, complicated work process and difficulty in communicating construction information. Therefore, the field manager could not perform the quality inspection and defect management work in time as well as the reliability of recorded quality and defect data was decreased. The primary objective of this study is to propose a quality inspection and defect management system using information technology which enables field managers to efficiently gather the information of defection in apartment housing. It is anticipated that the effective use of the proposed system would be able to imp개ve communication among the related participants and systematically accumulate data that might be used in similar construction projects.

Recently, apartment housing tends to increase 3-4% every year by economic growth and development of construction technology in domestic construction industry. According to this tendency, construction enterprises are providing high-quality and various residential space, and residents also want high-quality apartment housing without any defect. Construction company make efforts to decrease construction defects in order to satisfy all the residents, and to improve company value. However, it is impossible to have no defect in construction because construction works are combination of many different complicated process. Because of the responsibility for the defect, conflicts between construction company and residents have been occurred. This study suggests defects management method that can be used from defect register phase to defect repair phase with a function of smart-device of the high penetration rate. The effectiveness use of the suggested method might save defects maintenance time and improve resident satisfaction about construction quality.

Recently construction companies expand position for apartment house in construction market because of house supply rate increase and its amount. In addition, because the focus of house sale market has moved to customer from supplier, the importance of defect management is being issued currently. However, current apartment defect management is not satisfied with customer's demand for the lack of business process management, management organization, information feedback, and readiness for defect in construction phase. To solve this problem, this study proposed business process management improvement model for defect management. Proposed improvement model make information feedback, defect management business quality improvement, and improper process improvement through integrating defect management and quality management. It is expected to contribute to customer's satisfaction improvement and reliance improvement for construction companies.

The exposed concrete has been widely used in building construction. Therefore, many researches are presented to secure a proper construction quality of exposed concrete. Low quality and management absence, however, still remained in construction fields. Thus, many studies have been conducted to improve the quality, but defects still occur in the exposed concrete finishing work. In this study, the causes of defects were analyzed by process in order to prevent the generation of defects and to enhance the need for integrated management to secure quality. In addition, a case study and AHP analysis have derived the importance of defects occurring in the exposed concrete finishing work. The study concluded that the occurrence of the exposed concrete finishing work needs to be managed throughout the process, not the management limited by one process, according to the causes of the existing defects, and integrated management is required to prevent defects and improve quality of exposed concrete finishing work.

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.

The boom of housing market lead to build a lot of apartment houses concentrated on the metropolitan area and developing new city in 1980's made 2,000,000 houses. In this time, quality standards could not be satisfied with consumers' desire due to the policy about excessive supply and come from unexpected defects in the complected buildings. In $1980's\~1990's$, It would be performed on the study for defect prevention in apartment houses. It has contributed in no way to the reduction at the rate of the defect outbreak and the solution of consumers' dissatisfaction by flaws. The reason is that the study related defects is not linked and applied by the managing and controlling system, Therefore, the study will be analyzed out defect information occurred on apartment houses of domestic construction and classified by type features. As a result, it will suggest web-based feed-back system for getting systematic information and the practical use.

In general, defects cause a lot of maintenance costs and serious damage to various stakeholders, such as the owners, contractors or occupants of apartments. For this reason, a systematic and efficient defect management method is needed to minimize defect disputes. This paper derives a defect classification framework and proposes a defect risk assessment model for different types of defects. For this purpose, 6,000 defect items are allocated to the defect classification framework; these items are associated with 34 apartment projects over ten years old. As a result of this analysis, it was confirmed that the defect risks are concentrated in the areas of RC and finishing work. Based on these results, it is necessary to prevent the major risks of defects according to their priority. Based on this research, it is judged that further research to develop a method of managing the risks of defects may be necessary.
