Profit, the performance of an apartment development project, is directly affected by the sales ratio, unit sale price, financial costs, land costs and construction costs. However, these factors fluctuate in response to changes in the environment, including various stake holders, and the profits fluctuate as a result. In order to ensure that profits are managed within target levels, these factors must be able to be predicted, controlled and monitored and managed up to the start, sale, and end stages of the project. The purpose of this study is to develop a profit risk management model for apartment development projects. The results of this study will contribute to the establishment of academic basis for the dynamic management of project profits that fluctuate with time and environment. And in practice, it will help project developers manage their business revenue to the proper level. In addition, the risks that occur from time to time can be identified quantitatively and visually, and it is expected that it will be easier to derive consensus points for smooth business progress by reducing conflicts of interest among stakeholders.

In the domestic construction industry, large-scale housing construction projects are being carried out by construction companies with competitiveness in the domestic top 10, it is said that the competence of the construction engineer is a factor for the success of the project. In Korea, there is National Competency Standards (NCS) that systematize contents of knowledge, technology, and attitude required in order to perform job in industrial field as the importance of individual ability is systemized in the country. Therefore, in this study, defined the detail competence in construction administration works, and examined the level of competence and degree of impotance detailed competency of construction engineers using AHP analysis & ANOVA. As a result, it was found that the current capacity of the Engineers in the apartment construction work is insufficient compared to the level of the competence they think they have, and that they have different competencies depending on their work experience and job position. This means that if the career is accumulated, the capacity that is possessed naturally will be changed. Therefore, it will be necessary to improve the capacity of the construction engineers who have a short work experience and a low job level.

In planning phase of Public Multi-Housing Projects, it is required to develop the methodology and criteria for fair cost prediction with influencing power from planning phase to occupancy phase. Many studies still have focused on the prediction of cost by multiple regression. However, there is no logical explanation about the influence of nonmetric variables for the prediction of cost in planning phase. Accordingly, this research pursues a cost prediction model including nonmetric variables for use in planning phase. There are 3 steps of this research : 1) Finding the factors influencing construction cost and assigning variables for a multiple regression. 2) Conducting a dummy regression analysis with nonmetric variables and model validation by comparing actual cost data. 3) Developing the ratio of RC structure cost to wall structure cost by using cost predection model. The results could establish cost prediction process including the influence of nonmetric variables and the ratio of RC structure cost to wall structure cost.

우리나라의 건설산업은 70년대에서부터 지금까지 압축된 경제성장 과정을 거치면서 인구의 도시 집중화 현상에 따른 엄청난 물량의 아파트 건설로 숨가쁘게 물량 공급에만 급급해 왔지 상대적으로 건설시공의 효율성과 합리적인 건설관리에는 소홀하여 왔다. 이는 곧 반복되는 부실시공과 대형 건설재해를 유발시켜 건설업에 대한 대중적인 이미지 실추는 물론 품질과 안전관리가 국가적인 위신문제로까지 대두되게 되었다. 이러한 시접에서 건설산업의 문제점을 풀어나가기 위한 개선책으로 등장하게 된 것이 CM이라고 생각한다. CM을 통하여 설계와 시공을 통합관리하고 현장 시공과정에 내포되어 있는 부실 요인을 찾아내어 제거하고 시정조치하고 이를 유사 Project에 Feed-back시킴으로써 점진적인 향상(Progressive Improvement)을 이루어내며 제약된 자원을 효율적으로 이용하여 원가를 절감함으로써 건설산업의 경쟁력을 강화시켜 나가는 것이 곧 CM 활용의 효과라 할 수 있을 것이다. 본 논문은 15년간 현장소장(Project Manager)의 경험을 바탕으로 CM기법을 건설현장에 적용 사례한 결과를 정리한 것이다.

Housing culture has rapidly changed since apartments were first introduced in the 1970's. Among our living spaces, particularly, the kitchen reflects our lifestyle and its changes are more remarkable. Activities in kitchen areas include a diverse range of behaviors such as greeting guests, conversation, and family gathering besides cooking and dining. kitchen areas would not be the dedicated housewives' area, but rather a space for all family members. Kitchen areas become a 'living center' where all family members get together and have various family activity. This housing project was designed for the double income family who is consisted of 4 persons. The total area of Apt was 237.6M2. A residence is always comfortable, resting, and consistent for the family. Intimacy image, functional equipments and space, healthy materials were used for this project.

Construction projects have unique characteristics that these may be carried out by contractors thus, cost should be estimated before execution. The importance of cost estimation and cost check has become increasingly emphasized in all phases of construction project that would be performed numerously. It is needed that owner have to estimate reasonable budget, and contractor should predict the bid price. However, there are lack of standard cost estimation method before quantity takeoff, cost analysis method, and cost database thus, the method of area cost, such as square foot method, is as used as ever in Korea. Therefore, this research suggested standard cost database structure CUBE, and analysis method of item quantity per one household categorized by area type. Whereafter, database of all item quantity of finish work has been built with 90 building cost data, and validated it's availability. In this respect, the suggested method and the findings from this research are expected to help enhancing the efficiency and productivity of cost estimation in Korea.

With the intensifying of price competition and structural diversifications, the uncertainty of the domestic housing market has been increased. This highlights the importance of the planning stage of construction projects, and the increased need for a higher level of accuracy in approximate estimates. Currently, a number of research and development programs to calculate construction cost at the initial planning stage are being conducted. However, there are few cases in which local characteristics are considered in deriving the results. If local calibration can be conducted during estimates, more accurate cost estimates will be enabled. This could also play a major role in ensuring the success of a project. Therefore, the purpose of this research is to develop a calculation methodology and a model for a local index based on the historical data of public apartment buildings, and to derive a local index that supports accurate construction cost estimates.
