Result from Amendment of Apartment Houses Decree Customer Service, Recently, the starting point of Defects Liability changed "Criteria of Completion date" to "Delivery date to Divided property". Through the Law amended, There are some inconsistency between "Claim for repairing defects" and "Period of security deposit for repairing defects claim". If someone bought a house after Completion date, Purchasing period of "Claim to security deposit for repairing defects" lapsed without renewal. This research is to identify problems and solutions for improving the system.

In this study, I have researched into the causes of defects in apartment house, The results of this study are listed below. (1) Water leakages which result from land sinking and cracks, results of misuse of back filling method, are the main reason of defects in civil engineering work and architectural work. (2) Inexperience and unwillingness are the main reason of defects in plaster work. (3) In windows work and painting work, the main reasons are lacks of precision construction and efflorescence resulting from outdoor air, respectively. (4) Defects in waterproofing work and electric work result from fault construction by low unit Costs. (5) Equipment work requires uses of standardized construction materials and management, and landscape architecture work requires minimizing human mistakes, for instance, degin carelessness. For the reasons stated above, the causes of defects in apartment house are insufficient construction labors, inferior construction materials, urgent construction process time, and conscientiousless industrialists who only seek after a profit margin.

In this study, although the diversity of tiles in the expanding housing market is increasing, cases of defects in building interior tiles that occur due to limitations of existing tile adhesives and construction methods were collected, and among them, the relationship between the coefficient of thermal expansion and the occurrence of defects was analyzed. One-way ANOVA was used for the analysis method, and as a result of the analysis, it was analyzed that the difference between groups in temperature difference and humidity difference by defect type was significant.

The construction market has gradually become complexity, variety and specialization, and then owner's requirements about quality has become various. In order to solve the problem such as stated above, advanced constructions in United Kingdom, Japan and United States have introduced warranty contract which is warranted to quality and performance for need of owner in determined term to ensure the quality of construction since 1960s. However, the interior of a country encounter another problem result from defects liability what indefiniteness of defects standard, excess responsibility period, social recognition of be identical fraudulent work and defects, and contract with ascendancy of owners. etc, so builders concerned more excess defects liability than the quality of construction. The purpose of this study is to analysis of warranty contract in order to solve the problem such as stated above.

The recent increase in lawsuits and disputes caused by defects in apartment houses has been highlighted as a social issue. To solve this problem, studies were conducted on the type of defects in apartment houses. However, the problem has not been resolved amicably. Accordingly, it was emphasized that it was necessary to lay a groundwork for research on the types of defects by type of construction work in the recently constructed apartment houses and to present countermeasures and preventive measures for defects later. Therefore, this study investigated cases of defects in apartment houses and analyzed types of defects through PMIS and defect reports. The main purpose of the research is to present the causes for major types of defects by identifying the types of defects in apartment houses and to lay the goundwork for the study of countermeasures and preventive measures for each type of defects in the future.

Leakage defects account for a significant proportion of defect cases in modular homes. There are factors that can cause leakage defects at each stage, and quality control measures are required to minimize them. An improvement plan to prevent leakage defects was applied from the design drawings to the site of a modular public rental apartment complex in Sejong City 6-3, and a quality control plan was proposed to minimize leakage defects in the remaining process processes.

As the use of advanced quality materials in constructions has been increasing since 1980 with the improvements in the quality of life and economic scale, there has been drastic increase in constructions using stones for the internal and external construction materials. However, the reality is where many problems rise due to improper construction and management of uncertified stones which shorten the expiry date of the stones and act as the factor causing defects in buildings. Such defects not only bring economic losses but also influence consumer choice and act as risk factors to demand expansion of stone market. Therefore, the object of this study lies on proposing plans to prevent personal and economical losses due to repetitive defects by deriving the types of defects generated by process in stone constructions and identify the causes. Also, proposing construction process management plans as the measure for defect prevention, analyzing problems of stone constructions followed by the whole proves of design, construction and maintenance of stones, and solving such problems through appropriate participation of professional consultants depending on situations.

As the era of the Fourth Industrial Revolution arrives and the culture of contact-less was established due to the long-term COVID-19, the construction industry is striving to develop smart home services to expand the scope of information and communications technology (ICT) to provide convenience to residents. However, various defects are occurring in information and communications technology facilities in apartments, and related research is lacking. In this study, case studies and research methods of related prior studies are analyzed as a basis for identifying the types and causes of defects that occur in information and communications technology facilities. To analyze various studies, we divided them into studies on smart home Internet of Things (IoT), information and communications technology construction of apartments, and investigated their features and limitations. Plus, future research will be conducted on apartments within 10 years of completion among apartments completed by domestic construction companies to supplement the limitations of prior research. In addition, we will prepare basic data on defects of ICT construction by analyzing the major causes of defect types through the analysis of defect types and frequency by detailed work type of information and communications technology construction.

As the number of defects in apartments has increased recently, lawsuits and disputes related to defects have also increased. As a result, the loss of time and money is enormous. Therefore, fundamental measures are needed to reduce the occurrence of defects. Therefore, the purpose of this study is to propose a plan to reduce defects, focusing on window construction. To this end, existing studies were reviewed, and data from domestic construction companies were collected and classified to organize the types of defects. Based on the classified data, eight types with a high incidence of window glass were analyzed according to the time of occurrence, and the cause and causal relationship of the defect were schematized. It aims to identify the degree of possibility of recurrence of defects for each of the eight defect types for experts and derive key management elements using the RII method. Therefore, the goal is to select key management elements of window construction that actively reflect the characteristics of the construction stage.
