The purpose of this study is to provide the feasibility of apartment remodeling types in DaeJeon City. This study was conducted by survey for the residents' perceptions of the apartment remodeling. In addition, this study estimated the cost according to remodeling types by comparing it with that other apartments in DaeJeon City. By doing so, this study evaluated the feasibility of remodeling. The results of this study are as follows: 1. Not only the level of the residents' perception but also the intention of apartment remodeling was high. 2. The cost of remodeling was similar to that of residents had answered at questionaire. Thus, the remodeling cost proven to be very reasonable. 3. The cost of horizontally expanding remodeling type was cheaper than that of moving within the same apartment complex or into the new apartment. The cost of others (duplex, expansion or reduction of household) are cheaper that of moving. But one of the difficulties in carrying out these types lies in the fact that the remodeling should be performed in the apartment complex or building. Accordingly, this study proposes that horizontally expanding remodeling type is more feasible in DaeJeon City.

The present remodeling makes almost no difference from rebuilding as all the building materials are removed remaining frame structure only. And, in case of vertical extension of building, higher construction cost and safety problem occur. The Ministry of Land, Transport and Maritime Affairs, therefore, recommends customized remodeling that can be made in light of the resident' needs such as parking lot, elevator, bathroom, and room for the alternative of remodeling of vertical extension of building. The purpose of this study is to present real data that can be referred to the constructor's decision making before starting the remodeling, by investigating and analyzing the weight and importance between evaluation factors for customized remodeling at the completed time of remodeling. Accordingly, the factors were divided into environmental factor, social factor, and economical factor, and the survey was performed for the residents living in remodeling houses. In addition, for the professionals, AHP (Analytic Hierarchy Process) has been carried out for the priority in the customized remodeling. For environmental factor, the level of importance made difference from that before remodeling, except parking level. For social factor, every item, including psychological satisfaction and community satisfaction, made difference. For economical factor, the recognition level of importance in rent made difference, except sale price of the factor for price satisfaction. In case of the factor for cost satisfaction, it was checked that construction cost and administration cost both could be considered important. As a result of AHP, the most importantly emphasized item was construction cost, and sale price, administration cost, residence structure, and parking lot were followed by priority in order. This study could contribute to reliably settle down customized remodeling by giving reasonable and substantial help from the analysis of the differences in the customized remodeling items before/after the remodeling.

The purpose of this study is to suggest the improved methods for cost sharing in apartment remodeling projects. Case studies on apartment remodeling projects with different plan type were analyzed and compared. Cost sharing estimated by 'proportional rate method' shows similar results estimated by 'return on investment method' in case of similar area ratio of existing plan to remodeling plan. Otherwise cost sharing estimated by 'proportional rate method' shows great differences comparing the results estimated by 'return on investment method'. Although return on 'proportional rate method' is widely used, it is not proper to estimate cost sharing when each householder's contribution for the project varies, such as considerable differences area ratio of existing plan to remodeling plan. Improved cost sharing method is needed taking into account project contribution and characteristics.

In this apartment market, many apartments are being reconstructed within even less than 20 years from their first construction. This entails many problems in environmental and economical facets, for which many researches are under way in several institutions and universities. International cases show that the international trend goes for remodeling of maintenance, management, and repairing rather than new building. The purpose of this study is to investigate the factors of cost evaluation for establishing the time period of apartment based on durability of material and equipment while considering the economic feasibility of apartment, when remodeling as a concept of sustainability regarding building is being vitalized. This study investigates the proper period of remodeling in consideration of weight accruing to the LC(Life Cycle) and cost based on the standardized durability. The weight of cost, period establishment analysis, and LC according durability varies the data values of remodeling periods. The physical durability and cost from this data enable the investigation into not only the repair period of individual materials of the apartment but also remodeling period.

Considering the present development situation of rental apartment since 1982, the supply of rental housing for low-income dwellers has contributed a amount of quantities, but has been deficient qualities in housing policy. To propose the device of remodeling for low-income dwellers in deteriorated apartment, this study investigated the characteristics of maintenance cost and the residents'consciousness of remodeling by rental apartment types. The results of this study were as follows; The annual maintenance cost of permanent rental apartment was 14,249 won/$\textrm{m}^2$$.$yr, that of fifty years period rental apartment was 13,372 won/$\textrm{m}^2$$.$yr. In the case of remodeling in deteriorated heating system, the principal decision factor of choice was showed “economics” as priority. Residents in rental apartment preferred remodeling to reconstruction, and unit heating system to central heating system.

This research is aiming to specify the requirement of the investment such as intial cost, running cost earning rate to make effective investment considering the purpose of remodeling and economical value of store building enough to meet the initial purpose of remodeling. The review of earning for economical evaluation was performed by the on-site auditing on the structure and function of the building and applying the assessment simulation program, which is to find the possible business model to identify the requirement of building owner through case study. After the research, the following results are obtained. First, it is important that many aspects should be carefully analysis and the best method should be selected as characteristics of remodeling can be defer each other in their implementations. Second, though the remodeling of exist building to promote the functions has been applied, no suitable assessment tool has bee developed for deciding the level of remodeling in the view of economical efficiency so far. Third, the economical benefit was evaluated by analysing annual earning rate which is applied by investment items and recovery period for the investment. More specific date base should be established to apply the suggested economic acessments in business enough ti forecast the future circumstances. More researches should be promoted on the area continuously as well as the integrated economic evaluation of remodeling on existing building.

If we build new building after demolition of commercial building that is located in the downtown, it will be caused a social and environmental problem as wasting of resources and generating of waste. In this study, I investigated about remodel ins, this conclusion is given below. 1. Reconstruction cost is 2.1 times, and construction period is 1.4 times as much remodeling. So remodeling has an advantage. 2. For repairing and reinforcing timeworn building, we reinforced it as using carbon fiber sheet (girder, slab) and injecting method steel plate bonding Also, we tried to maintain efficiency of new building as using epoxy to protect concrete crack. 3. In the side of waste products and cost, remodeling has much more advantage than reconstruct. But demolition used construction period much. Because it had to be reused as repairing and reinforcing. And there was no difference between remodeling cost and reconstruct cost. If we develop research with enterprise.university.laboratory to exploit material and equipment and to train specialized engineer who will has a capacity to know construct repair and reinforce, it can be attribute to prevail remodeling in new construct market.

1960년대의 경제개발계획 이후 한국 건축물들은 고층화되고 현대화되었으나, 시간이 지남에 따라 유지관리의 개념 없이 지어졌던 과거의 건물들을 전면 철거하고 신축하는 재건축이 활발히 진행되었다. 재건축을 추진하는 과정에서 자원과 건설에너지의 낭비, 건설폐기물의 대량배출, 주거환경의 악화 등의 많은 문제점이 드러나기 시작하였고, 세계적인 환경보전의 움직임과 더불어 리모델링의 방향으로 전환하지 않을 수 없는 상황에서 한국정부의 정책적인 지원으로 한국 건설시장도 방향전환이 이루어지기 시작하였다. 하지만 경제적인 측면에서 리모델링 공사는 재건축에 비해 열악하여 리모델링 시행의 걸림돌로 작용하고 있다. 따라서 리모델링을 활성화시키기 위해서는 노후 공동주택 거주자의 경제적 부담을 감소시킬 수 있는 요소기술의 선정이 시급하다. 이를 위해서 본 연구에서는 리모델링 공사의 공종분류 체계를 설정하고, 이를 근간으로 리모델링 공사의 비용데이터와 신축공사의 비용데이터 분석을 통한 $1m^2$당 공사비를 비교한 후, 리모델링 공사의 경쟁력을 확보할 수 있는 요소기술을 제안하고자 한다.
