Feasibility analysis is a crucial key to success or failure of housing project. Existing feasibility analysis in construction company is based on intuitive approach rather than systematic approach. Usually feasibility analysis in a narrow sense is a financial analysis of project. Feasibility analysis focused in this study is confined to the matter of finance. So, the purpose of this study is to analyze the sensitivity of financial analysis item about profit rate by means of monte carlo simulation and this will improve accuracy of feasibility analysis and decision making.

내년부터는 건설근로자 퇴직공제대상 사업이 '5억원 이상 공공공사'와 '20가구 이상 공동주택'으로 확대된다. 또 사업주가 내는 납입금액이 1일 4,000원으로 높아진다. 건설교통부는 불안정한 고용과 낮은 임금 등 열악한 환경에서 일하고 있는 건설 일용근로자의 복지를 확대하기 위해 이 같은 내용의 퇴직공제제도 개선 방안을 마련했다.

In the resent years, the importance of VE (value engineering) and LCC (life cycle cost) analysis for apartment building construction projects has been fully recognized. Accordingly theoretical models, guidelines, and supporting software systems were developed for the value engineering and life cycle cost analysis for construction management including large building systems. However, the level of consensus on VE and LCC analysis results is still low due to the lack of reliable data on maintenance. This paper presents time dependent LCC model based value analysis method for rational investment decision making and design alternative selection for construction of apartment building. The proposed method incorporates a time dependent LCC model and a performance evaluation technique by fuzzy logic theory to properly handle the uncertainties associated with statistics data and to analyze the value of alternatives more rationally. The presented time dependent VE and LCC analysis procedure were applied to a real world project, and this case study is discussed in the paper. The model and the procedure presented in this study can greatly contribute to design value engineering alternative selection, the estimation of the life cycle cost, and the allocation of budget for apartment building construction projects.

Work delay is the one of facts that make the reliability of construction business decrease. Building a causal classification system of work delay and deducing the managemental item for it gives a great competition to the construction industry. It is, however, so rare to study about work delay so far. Therefore, this research analyzed a questionnaire, which is focussing on the public apartment construction, to look into the causal root factors and deduce the work delay factors. Finally, we suggest a major managing point to remove effectively the work delay factors.

Markets for the apartment remodeling projects will be a major portion of the construction industry in near future. However, only partial remodeling works in the apartment were done so far. This situation caused bad impact to expand the remodeling markets and less profits of the remodeling projects. In order to solve this problem, many other researches were done previously to Improve profits of the apartment remodeling projects. However, the results are too theoretical to implement them and Improve profits. In this research, profitability influence factors that are possible to improve effect of the remodeling works are selected and analyzed through several studies. Then, correlation analysis is performed between the improvement level in the remodeling projects and the numerical profitability based on actual cases. The result clearly shows that some improved remodeling items are strongly related to the profit. These results lead us to the strategy to follow for the purpose of increasing profits of the remodeling projects.

After IMF bailout crisis in Korea, project financing has been employed as a major funding vehicle for the housing development. In 2008, the recession of housing market due to the global financial crisis had an significant impact on the increasing insolvent site of PF based housing development project, resulting in serious impact to whole economy as a chain effect. In order to resolve this vicious circle of bankruptcy, the major construction companies were urged to take over the insolvent sites and invest to them for normal project exit, and finally play a critical role in normalization of market. Therefore, this study aims to define the core factors for decision making to invest to insolvent site and find out differences among constructors, developers, financial lenders. The results from AHP analysis, the profitability was the most important factor to constructors. Moreover, even though the location merit is little less, through competitive price, we can assure that stable profitability is most important factor to decide to invest in insolvent site. In conclusion, the price is cheap, is highly feasible, if the land secured, major construction company will participate in a PF business investment. These findings were verified by the investment case of major construction company.

Until now, the domestic construction market has been formed focusing on new construction and reconstruction in the apartment industry. Recently, however, the remodeling market for old structures have shown a tendency towards land shortage and land price increases in the major cities : the reinforcement of regulations regarding reconstruction ; expenditure reduction and the solving of environmental problems by regarding old structures is pursuing low costs and maximum efficiency. The interest in remodeling is increasing, however, remodeling has not been successfully initiated in the apartment division for a reasonable period of time. Consequently to acquire mutual agreement for remodeling from the residential occupants. In order to evaluate profitability, it is necessary to set priorities and reasonable criteria for remodelling and to this end, it is also required to assess each fact of remodelling in view of both customers and supplied.

The importance of the life cycle cost analysis(LCCA) for apartment housing remodeling projects has been fully recognized over the last decade. Accordingly theoretical models, guidelines, and supporting software systems were developed for the life cycle cost analysis of apartment housing remodeling systems. However, the level of consensus on LCCA results is still low due to the lack of reliable data on remodeling activities for safety diagnosis. in order to predict the reliability based LCCA of the given case, suggested the remodeling strategies level after reviewing other related materials. Apply the real information of the economic index. And based on such analytical measures, remodeling and operation cost and LCC in remodeling strategies level have been predicted; suggests the basic information about remodeling interventions level for the apartment housing. The LCC analysis models and the fuzzy logic based safety assessment presented in this study can greatly contribute to the value-oriented design alternative selection, estimation of the economic analysis, and the allocation of budget for apartm.

Gangform is used as exterior wall forms in the most of apartments. Existing system forms developed for high-rise building, RCS and ACS, are too heavy and over-designed to be applied to general apartments, leading to higher costs. A more simplified rail Gangform(R/GF) is also used, but it depends entirely on T/C for the lift like Gangform. The T/C's legal inactivity time for moving Gangform and materials has increased, and the higher allowances have to be paid for overtime work, thus causing to the cost increase and time delay. Therefore, this study aims to develop an automated Gangform climbing system that can be used universally and economically in apartment houses. The use of the development system is expected to improve the safety of Gangform operations and reduce the workload on T/C.
