There are certain types of construction that produces many defects during the construction of apartment buildings. It may be due to construction errors in the type itself, but more often, it is due to defects derived from other types of construction. Thus, to reduce such secondary defects and prevent fundamental defects in particular types of construction, academic research on the types of construction causing secondary defects should be actively conducted. In addition, as claimed in this study, the industries should work harder to improve the quality of the type of construction that causes secondary defects, rather than just trying to improve the ostensible problems. If the efforts of each sector are backed up, the disputes over defect repair in apartment building construction will reduce in general, which in turn will lead to a reduction in national loss within the construction industry.

It is important to utilize an efficient quality management platform because the management of deadlines at construction sites requires rapid and accurate processing of numerous defect data in a short time. In this study, 30 domestic patents for defect management and image analysis were analyzed to examine the development status of quality management platforms using mobile devices. As a result of the analysis, research on automatically detecting defects using artificial intelligence has been actively underway in recent years, and advanced IT technologies have been converging in various ways into linked services.

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.

In the 1970s, increasing penetration of the housing co-housing policy, reconstruction be a great success to improve 1990‘s Old aged apartment's performance. However, in case of reconstruction, it causes the problem such as city environment destruction, resource waste, real-estate speculation etc. With the trend of sustainable construction and resource recycling, remodeling gets more attention than before. In case of country's remodeling, conventional method causes some problems such as delayed construction period and increased cost. Therefore, efforts that obtain economical efficiency are required to power remodeling through use of prefabrication method like PC technology that is useful for reduction effect of construction period, cost and site labor and excellent quality. This research indicates reduceing factor for facilitating prefabrication method and technology selecting framework through specific of Expanding Floor method and remodeling cases to increase the efficiency of remodeling, considers construction parties approaching plan for prefabrication as occasion that powers remodeling.

Recently, block and permeable pavements have been placed in apartment complex. However. it is hard to decide the cycle of maintenance and repair due to lack of performance evaluation criteria for these pavements. This study carried out life cycle cost analysis(LCCA) to present resonable alternatives of the pavements by considering initial construction cost, maintenance and repair cost along with the cycle of repair. According to results of LCCA, the interlocking concrete block pavement is the best alternative when the repair cycle of 20years is assumed, while asphalt concrete pavement is the best alterative when the repair cycle of 10years is assumed. Therefore, the repair cycle is most important factor to select alternative. Also, it is necessary to develop resonable performance evaluation index to quantify the cycle of maintenance and repair in the future.

The Housing Performance Rating System, enacted on 9 January 2006, an active measure containing provisions on improved quality and advanced performance of the Fire-Protection System for equalized ability to secure safety of life to some extent, is a desirable policy in fire-safety regard. The study of theoretical background of each performance rating section for the purpose of active and wide application of The Fire-Protection System category of the Housing Performance Rating System currently in effect internally. In accordance with the result of the study, the reform measures for the currently detailed evaluation criteria have been suggested to improve the performance of the Fire-Protection area of The Housing Performance Rating System currently being in force based on the assumption of prior settlement of the following; upward settlement of the point distribution standards on the performance ratings of each head backed up by an institutional Government policy with overriding priority; and urgently enacted Fire-Protection related laws and regulations.

In contemporary society, there is a notable rise in single-person households, coupled with an increased demand for residential spaces, necessitating the exploration of suitable housing solutions. Modular architecture is gaining prominence as a method to deliver cost-effective and sustainable living spaces efficiently. This study introduces a method for optimizing the design and construction processes of modular building units through Building Information Modeling(BIM) technology. It involves an analysis of factors that enhance living quality and meet the housing needs of single-person households. Utilizing BIM, a resource-efficient and cost-efficient modular apartment unit has been developed. BIM facilitates the visualization and integration of architectural components, thereby reducing design errors and enhancing productivity. This research evaluates both the benefits and constraints of modular architecture. Modular constructions, when combined with BIM, emerge as a potent solution for housing challenges, enriching the quality and variety of residential options. Nevertheless, considerations such as technical prerequisites and financial implications are also discussed. The study showcases the potential and merits of utilizing BIM for designing apartment units tailored to single-person households, offering a viable approach to ameliorate their living conditions.

Because of preferential treatment in PQ judgement, many construction company got the certification of ISO 9000. But the main objective of them was just certification itself. The ISO 9000 certification which was composed of 20 requirements was a standard just for the manufacturing industry, so it was difficult that it was applied to a business of construction industry. In these reasons, they have revised ISO 9000:l994 which was composed or 20 requirements to ISO 9000:2000 which requests to focus on business process. In this research, we'll develop a System for Project Quality Plan that is related with information of site process in an apartment housing project. This system is intended to increase use of project quality plan in construction sites based on the construction process.

정부의 주택 2백만호 건설이 본격 추진되면서 건설인력난, 자재난 등이 심화되고 있어 설비공사업계가 이의 대책 마련의 일환으로 건식공법 개발에 부심한 노력을 기울이고 있다. 건식 공법은 자재의 대량생산으로 현장에서 조립만 하면 되기 때문에 시공이 간편할 뿐만 아니라 비숙련공도 거뜬히 시공할 수 있어 인건비 및 자재난 등을 해결할 수 있다. 게다가 건설공사에 있어서 가장 중요한 공사비 절감, 공기 단축, 품질의 표준화 등의 효과를 누릴 수 있기 때문에 설비공사업계에선 이의 적극적인 도입이 더욱 필요한 때이다.

This study analyzes the necessity and situation of the improvement of housing quality control system for the consumer. we find several defeats of the Housing Quality Control System in Korea. Especially there is no any organization that manange the total housing quality control. So this study suggest the home warranty system should be established as soon as possible for protectings home-buyers and improving housing quality.
