More than 50% of the existing buildings in Korea are over 15 years old. Therefore it is necessary to be held reconstruction or remodeling deteriorated buildings more efficiently. Especially, since remodeling project reserves existing structures, it requires less period of project and construction period compare to reconstruction. It is possible to minimize uncertainty in communication between participants and able to manage information and construct efficiently in remodeling projects. This paper is first step of integrated BIM-based whole lifecyle management of apartment remodeling process. It suggests 3D laser scanner specification factors and site constraint factors for mapping between two groups. Therefore it will contribute to develop mapping algorithm of two groups and find optimal combination for apartment remodeling.

The apartment reconstruction project is making some problems, such as delay of lack specialty, conflict between project owners and cost increasing etc. The enforcement process of project are very complicated, the term of project is long and too many project owners are participating. For this reasons. it is always in the face of uncertainty. To promote the reconstructing project successfully. we need to make risk management process to get rid of uncertain factors which occur in forwarding the reconstructing project This study has for its objects. First, suggest the best way of risk analysis to manage risk factors systematically and efficiently recognized in The Apartment reconstruction protect. Second, furnish basic data to build the risk managing system of The apartment reconstructing project.

Reconstruction and remodeling have been introduced as a part of renewal (redevelopment) projects for old apartments built after the mid-1970's and government policies for revitalizing each project has been changed continually. However, the frequent changes of the policies have caused conflicts among business entities in selecting business methods. The conflicts from their early stages have made serious problems in the entire business process. Therefore, this study deduced factors of business selection by applying comparison analysis between the two business projects on how certain factors have an influence on selecting reconstruction and remodeling business projects. Based on the analysis, four categories and 26 factors were finally selected. After then, the priority of each selection factor was deduced through the AHP method and PROMETHEE method used for analysis of relative importance and impact values regarding to the business selection.

Most old apartment housing have been replaced with new ones by means of the reconstruction. But with the change of the construction environment, remodeling is introduced as a new alternative for the replacement. Remodeling is expected to reduce national loss owing to the early reconstruction of old apartments resulted from economical and functional deterioration. But there still remains a lot of problems to be first solved for Remodeling. One of those is to figure out how to perform an economic feasibility analysis effectively. The researches of remodeling done under the rally stage are not sufficient in economic feasibility for apartment housing. Therefore, this paper suggests an effective method for the economic evaluation of remodeling projects focusing on a rental high-rise apartment.

Established redevelopment and reconstruction projects were unified into one law in 2003 when the 'Act of Urban, Residential and Environment Improvement' was enacted. However, the act only focused on the improvement of the physical state of residential environments established by maintenance projects. In order to be effective, the law also needs to improve the nonphysical aspects of the residential environment. While conducting our research and comparing it with past research, we identified the major factors of residential preferences in order to extract and analyze the nonphysical state of residential environments. As a result, we found that social and economic factors are significantly more important to residents than cultural factors. Also, we found that in each district studied the housing preferences were the most important in redevelopment and reconstruction with the exception of Sangdang-Gu (where the community was the most important factor) and Hungduk-Gu (where the social factor was most important). For future purposes, it is necessary to consider the variables according to each location in order to reflect the needs of the residents when building an apartment complex within the redevelopment and reconstruction district.

In recent years, there has been more reconstruction and redevelopment of apartments rather than efforts to consider alternative to extend the life time oh the apartments. It is essential to try to develop ways to adequately maintain and to use the apartment facilities efficiently in order to preserve earth environment and the limited resource. However, lacking research on the effects obtained through remodelling and maintenance have interfered with the vitalizing of the market. The objective of this study is to propose criterions and methods with which to evaluate adequacy of developing method. A survey was performed to investigate important evaluating methods in order to obtain advices that can smoothly progress improve apartment developing method. This study applied AHP(Analytical Hierarchy Process) methods for reasonable dependancy of developing in apartment. Through this study, the flow of apartment market is elevated to reaching the level in advanced nation.

Apartment housings that adopt a bearing wall structure design, which account for a majority of the housing units available in Korea, are not free from structural constraints that limit the extension of their service life. The resulting need for reconstruction from the ground up requires a massive consumption of resources and energy, and triggers environmental pollution resulting from construction wastes. As a solution to such issues, the government enforces incentive schemes to promote a remodeling-friendly rahmen structure design. Green Frame, which is a novel concept of composite precast concrete structure to support rahmen structure apartment housing buildings, can address the constraints of bearing wall structure and conventional rahmen structure designs that limit the potential for remodeling projects, while reducing the term of construction. Therefore, this study aims to analyze the characteristics of Green Frame and its absolute term of construction, and compare the terms of frame work construction in apartment housing projects adopting different structural design approaches to illuminate their differences. In the end, Green Frame is found to be capable of reducing the term of construction in apartment housing projects. As the term of construction is a very critical element of a construction project, Green Frame will ultimately prove to be one of the key enablers to ensure the success of apartment housing construction projects.

Recently, apartment-remodeling project is booming since various reconstruction controls are tightened. However, the project has difficulties because management systems used for apartment-remodeling projects are not available. Identifying and analyzing risk factors that are required for risk management, this paper suggests the risk level through paired comparison performed by AHP method and probability assessment for risk level analysis. It is expected that this research will be utilized to minimize the risk of apartment remodeling project and for basic materials to perform the project and helpful to change newly build-oriented construction into sustainable industries. Hereafter using the risk factor analysis data of this paper for this research project, risk management model is considered to be constructed.

Because a procedure is complicated and various related parties participate in the redevelopment and reconstruction project, it can be extended to diverse disputes when the relation with the related parties is smoothly adjusted. In particular, when the dispute occurs in a phase of occupancy after the complete construction, the regional residents-centric association must give up many rights of invisible parts caused by the construction company's profit maximization because they are short of professionalism about the business. Accordingly, this study is aimed at providing the construction project manager's dispute and claim process for responding to the dispute or claim reasonably and for obtaining the client's (association) rights for the reconstruction project, and at developing the checklist for obtaining the necessary documents by each phase, when the dispute or claim is made by the association against the construction company after the completion of construction. Through this study, the association can obtain the related documents in advance and can implement the reasonable response data when the dispute or claim occurs due to it. Also, it will enable the construction manager to analyze the project costs reasonably and will reduce the estimated wastes. That is, the work efficiency is expected to be improved.
