Compared with other industries, the construction Industry has many parties(A/E/C) as well as many types of construction activities. Especially, as for the remodeling project, the owner group the remodeling union consists of various stakeholders union and requiring the additional activities of demolition except for the existing new building construction project. Like this, the remodeling project has its own characteristics different from a new building construction project. As for the remodeling project, the Owner's decision making for a remodeling alternative has to be preceded, and other parties are required to propose a remodeling alternative which satisfies the Owner's requirements. However, because of time constraints, many types of problems occur during the decision-making process. In consideration of this, in this research, the authors would like to suggest a decision-making support system to help the Owner's decision-making in the early stage of a remodeling project. For this paper purpose of a remodeling decision-making framework based on Building Information Modeling(BIM) was suggested to help with the Owner's decision-making for each remodeling item and the decision-making support system was evaluated through Case Study.

To promote the remodeling project it is important to get apartment residents' consent. It is significant variable to determine project to progress smoothly from planning stage which committee of association establishment sets up to establishment stage of association. On average, it takes about 1~1.6 year in planning phase which means before construction phase of remodeling. Therefore, it is very important issue to get apartment residents' consent in planning phase. In this research, we focused on residents' opinion and proposed solution of conflict with gathering residents' opinion to proceed remodeling project. By setting particular remodeling situation, related residents represented as agents made effort to efficient coordination to reduce total duration of decision making. Therefore, we proposed multi-agent based on fuzzy inference to simulate behavior of decision making on remodeling project effectively. From this method, optimal alternative is selected by considering each agents' attributes which represented by fuzzy set. This research will develope to further research for realizing concrete multi-agent based on fuzzy inference considering all stakeholders in remodeling project.

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.

Housing development, particularly apartment buildings, has been increasingly growing due to the construction promotion policy of the government since the 1980s. However such a volume-oriented policy results in unfavorable side effect of substandard quality and early deterioration in line with the expansion in volume. As part of measures to deal with the problems, rebuilding and remodeling have surfaced as alternative recently. Remodeling is expected to create the more benefits, compared to the rebuilding, in cost, efficiency and duration. To come up with the solution to such a challenge, it's necessary to analyze the influence factors of remodeling. Hence, the study was intended to compare the remodeling in the aspect of influence factors. The results of this study is expected to the propose of effectual management factors of the remodeling construction.

Aging buildings over 15 years reaches about 74% of 177 thousand buildings in Domestic public buildings. Due to the aging building, the energy loss is a serious problem. In order to reduce the energy usage through improving the energy efficiency on the existing buildings, the government & the local autonomous entity conduct the energy efficiency projects through the remodeling, repairing & equipment replacement on the existing buildings. The green remodeling is applied to the existing public buildings in recently revised the act on the creation and support of green building. However, the standard is not obvious that the work scope of green remodeling, financing and project delivery method. This paper propose is to suggest project delivery system for vitalizing the green remodeling. Green remodeling is defined on basis of the occurring work under project life cycle based on the existing building process and the financing method for owners and companies and the project delivery system according to work scope of green remodeling are proposed in this paper

Recently, the architecture remodeling is rising as new alternative for activating the construction market as the interest toward life cycle of buildings has increased. But the reality is that current remodeling business is suffering various types of difficulties in its performance due to the absence of general management technology and factor technology in systematic performance procedure or evaluation, etc toward remodeling effect, evaluation on performance, imperfect system for reflecting user requirements and remodeling life cycle ; planning, $feasibility ^{\circ}\hat{E}designing^{\circ}\hat{E}construction^{\circ}\hat{E}management$ along with lack of overall understanding on remodeling. Accordingly, this research has attempted to search for an effective management method through overall understanding in project performance by presenting work procedure of remodeling project and analysis items for decision making, etc centered on early planning stage out of three stages called planning, designing and construction.

In 2020, it was estimated that more than 2.4 million households in South Korea are over 30 years old. That is, more than 40% of all houses in Korea are old and that they require proper rehabilitation. The two options to improve poor living conditions are reconstruction and remodeling. Compared to reconstruction, remodeling has advantages in terms of the construction period, cost, and environmental impact. As such, the current Korean regulations are more favorable for remodeling than reconstruction. Typically, several candidate floor plans are presented in the early stages of an apartment remodeling project. Extracting information about bearing walls and other structural elements from the multiple plans to compare those plans quantitatively is one of the essential tasks during the early stage of a project. To cope with this task, an automated data extraction method for walls and slabs from before and after remodeling plans is developed. Through the developed program, load-bearing walls, non-bearing walls, slabs, and weight changes after remodeling can be analyzed and visualized in a fast and automated manner.

Recently, remodeling construction project has been prevalently conducted in major city areas in Korea. However, remodeling construction project has a difficulty in conducting a construction because of non-existing drawing or lack of drawing information. To solve these problems, modeling techniques by using reverse engineering have been widely studied in other industries such as aerospace and automobile industry. But reverse engineering techniques have not been used in remodeling construction projects because those technology haven't supplied less accuracy during required time for surveying. So, this study suggests optimal method of acquiring accurate 3D laser scanner information for reverse engineering at interior remodeling project.

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.
