The domestic construction industry in the last 30 to 40 years has accumulated a large stock of buildings that are quickly and there physical age is quickly becoming apparent. Contemporary changes in architecture are fueling changes driven by the increased demand for these new services and facilities. The cost of energy and raw materials are on the rise, and dealing with the waist generated from the creation of new buildings is an emerging problem in the industry today. Thus, building remodeling has emerged as an alternative do to its increased efficiency regarding material usage. The participation of users in the development stages of a remodeling project is essential to its effective implementation in projects. The BIM model used for the design process of building remodeling is the most effective way, due to the increased efficiency gained in many areas. This study will examine a pilot project where a BIM based process was used in the remodeling of an apartment.

Building remodeling concept includes maintenance & repair and renovation. We have long-term repair plan and special repair fund system for the apartment maintenance & repair, but they do not operate well. And laws and ordinances are being revised in relation with renovation. However, more policy improvement and assistance are needed in order to activate the apartment remodeling project. Especially preferential loan and tax reduction policy and deregulation of building provisions are the main tasks for the apartment remodeling.

Since the beginning of our military history, we are continuously interested in supplying apartment for military officers. So we possessed 72,361 households and used in 2002 however, $18\%$ of those are over 20years and need to be remodeled Department of Military has taken this fact seriously To solve the problems, they built more new buildings, rent public buildings and remodeled the old one But, The procedure of present military apartment remodeling has many problems at the stage of evaluating the priorities in various remodeling projects which have been caused from lots of corps. I've reviewed the study of military apartment business and applied the AHP(Analytic Hierarchy Process) method which is effective to evaluate the priority in various groups' decision.

As of 2017, there are 848 million households living in apartment and 55.87% of Aged apartments over 15 years old. The allowable standard for remodeling the apartment is more than 15 years and the market for remodeling the apartment will continue to increase. For the success of the remodeling project feasibility analysis is important but the existing feasibility analysis of new construction and reconstruction is being used for remodeling feasibility analysis. Therefore, it is necessary to study the feasibility analysis of customized remodeling without increasing the number of households according to the building law. Purpose of this paper is to develop a feasibility analysis methodology for customized remodeling projects by deriving the factors affecting the formation of land prices and building prices in apartment. According to the concept of price formation of the apartment, the analysis method of the customized remodeling of the old apartment using the factors affecting the Land Price Indexes, Officially Assessed Individual Land Price, House Price Indexes, and Officially Assessed Individual House Price was suggested. The Stair Price Algorithm developed in this research can be utilized at the stage of selecting remodeling contractors after the remodeling housing association is established.

Purpose: Korean society has already entered an aged society but there aren't many evidence-based studies on the elderly-friendly design elements in the apartment environment, which is the main residential type in Korea. The main purpose of this study is to verify the necessity and expandability of the outdoor environment design in the public rental apartment complex through the evaluation of the effectiveness and satisfaction of SMG(Seoul Metropolitan Government) Cognitive Health Design Project in GR 1 apartment complex. Methods: The research subjects were GR 1-complex as experimental group and the nearby Wolgye Deer 1-complex as control group, both public rental apartment and located in Seoul. As a research method, the survey was conducted before and after the implementation of SMG project for residents of the apartment. A total of 200 preliminary surveys and 203 post surveys were conducted. Results: As a result of this study, residents' accidents related safety have decreased, and both the frequency of use and satisfaction of most facilities have increased. It is noteworthy that the increase in cognitive items in the post-survey. Also, 74.5% of the residents evaluated that the complex was better to live after the project was implement. Implications: The fact that the preliminary surveys were not conducted for the same person is considered as the limitation of the study, but it is meaningful in that it systematically assesses the effectiveness of the project on the cognitive health of the outdoor residential environment towards age-friendly city.

Alongside the increasingly larger domestic construction projects is the gradual rise in construction waste. Consequently, serious environmental problems emerge. The increase in demand for housing remodeling due mainly to the increase in national income and improvement of quality of life is the main reason for the increase in construction waste. This study was conducted as the basic study for the prevention and reduction of construction waste generated by apartment remodeling; it aimed at identifying the remodeling items and reasons. Toward this end, this study targeted apartments at least 15 years old and conducted a questionnaire survey to determine the remodeled sections and remodeling reasons. As a result of the questionnaire survey, the bathroom, floor finishing, and kitchen furniture recorded the highest ratios in remodeling. Old materials, aesthetic motivation, and pleasant living space composition were cited as the major remodeling reasons. This study is significant as a basic study for generating environmental and economic profits through systematic waste management. Further studies should develop guidelines suitable for construction waste reduction and recycling in line with the construction and demolition phases in case of remodeling.

In the process of industrialization of our country in 1970's, Korea's housing strategy has focused on housing supply. Rapid completion and supply of apartment house buildings have caused a problem of their early deterioration due to their poor quality. In 1987 Housing Construction Promotion Act, therefore, included new regulations on housing re-construction. In July 2001, other new regulations on remodeling apartment buildings were also included in the Act. Reconstruction and remodeling have been considered to deal with such problems. This study suggests an appraisal criteria if they can select reconstruction or remodeling method in conducting their apartment building project. At first, evaluation items should be selected by the criteria of function31ity and economical efficiency. Second, the selected item is screened by AHP and multi-criteria decision-making methods. The result of study shows that the owners of apartment units will be able to select reasonable alternatives through the suggested appraisal method

This article deals the investigations how to solve the social deficiencies of deteriorate apartments, which is a half cycle of a building and it goes slum clearance and redevelopment. And this proposes an active remodeling and design strategy, management, and housing policies for extending the usage of the resource. Most of apartment housing in Korea is built by the panel wall and slab structure system fur economic price. To remake is possible, even though not designed in flexibility and variation. The remodeling strategies are dwelling unification, transformation of two units to one or three units, addition of a room, changing into commercial and community required spaces, and reshaping of a envelop and facade by addition of a dwelling or dwellings, roof floors, change of materials and colors, and so on. And, all activities in structural aspect are proposed removal in upper part and addition in lower part of an apartment housing. Active remodeling cost a great deal compare to new construction, so any remodeling activities should be based on a minimal interfere and budgets to enhancing the quality in existing building. The final aim of an active remodeling is to enhance the quality in economic values, and to keep original state and to put on the new one in a small part. To promote the active and careful management and rehabilitation, it is necessary to give the positive incentive in terms of architectural law, bank loan, and any redevelopment project should get the remodeling record in national resources.

As people pays more attention to remodeling as a method to effectively improve, maintain, and manage building properties, it is important to ensure the economic feasibility of remodeling compared to reconstruction, instead of focusing on systematic regulations. In order to identify core technologies, the study set criteria to survey cost of a remodeling project by analyzing current status of remodeling projects. Based on the criteria, the study calculated average construction cost for five remodeling projects that were conducted recently, compared the cost with new construction projects, and examined major level works that are essential in a remodeling project. Based on the major level works, the study conducted interviews with construction experts to draw core technologies in design, structure and construction of a remodeling project.
