As data management and analysis technology advances, there is active discussion on how to utilize data generated in construction projects. Among them, the materials produced during the supervision work are highly useful because their generation cycle and format are regulated according to relevant laws. In this study, we analyzed whether the data produced during the supervision work in the construction phase of apartment housing can be utilized for project performance management. First, this study identified key data necessary for performance management through FGI with experts in the field of apartment housing. Next, we collected supervisory data from the case project and identified whether the data was generated, its cycle, and storage format. As a result of the analysis, the supervisory data contained various information that could measure the performance of construction projects and had the advantage of standardized data. In the future, utilizing supervisory data is expected to enable effective performance management of apartment housing construction projects.

Each year the amount of construction wastes increases at a rapid pace. Particularly, wastes from apartment housing projects that make up 89.14% of the total construction projects have increased about 48% as compared with those of the year 2000. Construction wastes are therefore rising as an issue related to environmental problems and disposal costs. And there are ongoing studies of the disposal, control and recycling of construction wastes. Mitigation measures for the wastes, however, have been a rare subject of research that focuses on waste-generating factors by activity during apartment housing projects. Given that, the purpose of this study was to categorize construction wastes by work type and to identify the factors causing wastes in order to reduce them. This study investigated the amount of the wastes from apartment housing constructions by activity as related to disposal costs, and examined causes in the ordering, transport, material management and construction stage, respectively. The analysis results will likely bring about expectation effects that help reduce the generation of the wastes by establishing action plans.

The government has enforced the Green Building Certification System since 2002 to resolve environmental pollution from building construction projects. The Green Building Certification System offers additional financial incentive worth 3% of basic apartment unit construction cost for apartment housing projects that have passed preliminary certification and has been revitalized drastically since 2006. However, after the system was put in place, comparative analysis of each item in certification criteria has not been performed yet in reference to actual certification cases. This paper aims to provide a comparative analysis of such evaluation items by studying green building certification cases involving apartment housing. Conclusions drawn herein are expected to provide a framework of continued advancement for the certification system subsequently.

Construction duration is very important as a factor which comprises three axises of construction management with quality and cost in construction project. In general project condition, construction duration is optimized while minimizing construction cost and securing required quality. However, in case of insufficient project time duration or delayed projects, project progress management is different from those of normal projects. These project areas need solutions to complete work within a given completion day. To time shortening the current duration of each typical floor of structural framework in apartment construction is investigated, and a basic time schedule planning for typical floor of structural framework in normal projects is planned. This study proposed 3 ways for time shortening of urgent project or insufficient construction duration project. Also, This study proposed detailed time shortening method and technical solution conditions while time is shortened.

In the large scale projects, it is difficult to manage every blocks because of the apartment housing project have repetitive shapes and structures. Therefore, it is necessary to divide construction site into work zones and blocks considering site plan, the number of units per each floor, arrangement of blocks, etc. In this study, 20 influencing factors on the grouping of work zones and formwork crew team formation are identified through case study and literature review. Factors are analyzed to determine the degree of influence through experts interviews. A systematic process of crew formation based on work zoning and the considerations by each steps are presented.

In this study, various factors affect on the reconstruction of the deteriorated apartment housing complex in the Taegu-City were analyzed. The conclusions obtained in this research were summarized as follows; 1) In case of 4 to 5 storied apartment buildings, those were main objects for reconstruction. The number of the buildings and households consisting apartment complex and the total building area and the ground area were appeared as major factors. Those factors were highly correlated with the consensus of reconstruction. 2) As a maximun area of reconstruction was limited, higher existing consensus capacity and its ratio affect negatively on reconstruction of deteriorated apartments. 3) The main motivation for reconstruction is disadvantages among the members of reconstruction association were main obstacles to reconstruct the deteriorated apartment buildings. Therefore, a resoanble alternatives for reconstruction plans and administrative managements were needed.

The purpose of this study is to analyze of profitability accordance to the different sales timing in apartment housing development projects. The adapted research method about public apartment hosing development projects by a private construction company is concentrated on the middle and large scale housing. The methodology for analysis of profitability through the change of timing for sales is analysed. According to this methodology, the difference of profitability by different timing of first sales is compared and analyzed. The results of this study are as followed 1)The major factors to affect the profitability for apartment housing development project consist of the timing of sales, the method of payment and the rate of sales. 2) The case study was carried out and then the profitability is analyzed the profitability for the three of cases is got worse when the sale after construction especially on the time of construction progress rate 80% is carried out.

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.

While many studies on feasibility analysis for housing projects have been released, the main focus was on economic feasibility and factors related to developers were not clearly identified enough to be used in practice. In order to establish a feasibility analysis model for apartment development projects requested by developers in Korea, 31 driving factors behind projects' success were identified under seven different categories. Criterions of the each factor were also developed, and weight of each factor was assigned by applying the Analytical Hierarchy Process(AHP). Finally, based on the Monte Carlo simulation, the feasibility analysis model was established, providing probability distribution of project's grade. The model was applied to 12 housing projects to verify its reliability, and found that the model properly filtered projects that are unlikely to be profitable, indicating reasonable reliability of the model. The model can be a useful tool for contractors, especially with less experience in analyzing project development feasibility.

This research is about Apartment Remodeling Upgrading Programme by Singapore Housing Development Board(HDB). For this study, we visited HDB and made field survey of the projects. There are basically three types of upgrading, namely, Precinct Upgrading, Apartment Block Upgrading and Flat Upgrading. Precint Upgrading refers the upgrading of services and facilities of the precinct. It involves the extention of open space, car-park, commercial space and additional covered linkways. These afford the residents greater convenience and comfort and generally enhance the environment of the community. Apartment Upgrading refers the upgrading of the block facade, improvements to the elevator, lift lobbies, letter boxes, trash chute and rain chute. The upgrading improves the quality of life of the residents. Flat Upgrading Involves the addition of space which may be in the form of a new Utility-room, replacement of old services, piping and equipment within an apartment unit. These provide the residents with a bigger and more comfortable living space.
