Recently, various construction projects are invested with plenty capital, manpower and resources. The advanced methods of the construction management is introduced to Korea. However, the cases which get involved in excessive cost frequently occur. We can explain it means that the cost management in the entire phases and the risk factors in its works has not been done yet as expected. Thus, it is necessary to unearth risk factors relative to cost management and analyse them for preventing cost-increasing and the success of projects. In this point of view, this study aims to identify the risk factors of the cost management focused on pre-construction stages from the perspective of construction management which is possible to take part in the whole phases and works in cost management. Also, the impact priority and grade of risk factors to cost-increasing are evaluated by using FMEA.

Total Project Cost Management System(TPCMS) was introduced with the purpose of increasing the efficiency of cost control for public construction project in 1994. In this paper, general perception of participants of the public construction project on the TPCMS was examined, and the problems in implementing the TPCMS was figured out through expert interviews and survey. Then better ways to implement the system were drawn based on the problems. To effectively manage the cost of public construction project, basically project cost should be estimated accurately in planning stage and managed based on it to have a project complete within the budget. In addition, the cost need to be managed in more systematic ways in terms of data collection and analysis, and the autonomy in managing the project cost given to the project owner needs to be expanded. Most of all, proper budget should be provided to prevent a project from delay through setting the priority of projects and proper budget allocation based on the priority.

Frequent design changes or unnecessary project executions due to illogical practice, lack of feasibility study and, hasty drive have raised problems of budget waste in Korean construction projects. Since the MOCT (Ministry of Construction & Transportation) published Master Plan for budget efficiency for government projects, there have been a lot of policy efforts for budget saving. However, it has been pointed out that cost management at the pre-construction phase, which greatly influences the cost still remains imperfect. The target cost for government clients is not being estimated reasonably, and cost controlling at the pre-construction phase is not yet being carried out properly for keeping the budget. Therefore, improved construction cost management at the pre-construction phase was proposed in this paper. The cost management systems of advanced countries were investigated for it, and the issues were drawn from the cost management systems of these countries. On the basis of the issues, the present conditions and problems of domestic construction cost management at the pre-construction phase were analyzed for suggestion.

Estimated project cost and executed sensitivity analysis for domestic 500 MW coal-fired power plants with monte carlo simulation. As a result of research, the basis of constant price in December, 2011 and 95% level of confidence, the project cost in case of not having adjacent power plant was 1,870 billion won to 2,330 billion won and the project cost in case of having adjacent power plant was 1,240 billion won to 1,590 billion won. In case of not having adjacent power plant is sensitive to civil construction cost but the other case is sensitive to material cost.

Successful implementations of domestic public construction projects have been increasingly concerned with the efforts to improve the inefficient execution. However, the existing factors causing the inefficient execution have been repeatedly occurred in many projects. This is because the previous studies have been concentrated on identifying the factors without in-depth analysis and systematic prioritization. This study has clarified the characteristics of the inefficient public construction projects, identified the causes, constructed their hierarchical structure, and analyzed the impacts on them. In particular, the critical factors causing the inefficient execution are prioritized by the outcomes derived from the questionnaire surveys, which is limited to the pre-construction stage. They are utilized in prioritizing the institutional and political improvements. However, in the future, the analytic and detailed guideline for remedying the factors causing the inefficient execution of a project should be studied, and their analysis will be extended to the construction stage.

As the Korean economy went into a recession because of the global financial crisis in 2008, in order to vitalize the Korean economy, the government raised SOC budget and made its execution earlier. To prevent increases in budget for the government financial investment projects, the government controlled the project cost of SOC construction projects by enacting 'Guideline for total project cost management' in 1994 and complementing the relevant system. However, different from government intention, the total project cost of SOC projects were increased drastically. Hence, the government authorities and research institutions insisted the necessity of supplementation and improvement for the total project cost management system. This research is to provide the improvement for the total project cost management system of domestic SOC projects. In this research, As-Is Model was adjusted considering status of the total project cost management in the current SOC projects. Also the cost management of construction projects between domestic and other developed countries was studied, analyzed and compared. Based on the above, problems related to total project cost management of domestic SOC projects were found out and an improved total project cost management was provided to improve these problems.

국토해양부에서는 건설사업의 생산성을 향상시키고 건설사업의 효율성을 제고하기 위해 건설기술관리법 제15조의 2에 따라 건설공사지원통합정보체계의 구성.운영에 관한 법률을 마련하고 1998년부터 건설사업정보화(Continuous Acquisition Life-Cycle Support : CALS)를 추진중에 있다. 건설사업정보화의 일환으로 건설공사비의 상당부분을 차지하고 개인의 소유권과 관계되어 있어 민원 소지가 많은 보상자료를 관리하기 위해 용지보상시스템이 기 개발되어 운영중에 있으나 보상비 지출의 핵심과정인 지급단계가 국가재정정보시스템과 별도로 운영중에 있어 체계적인 보상자료 관리 및 보상비 지급의 이력관리가 제대로 이루어지 지고 있지 않다. 이는 곧 부적절한 보상비 집행으로 인한 국고예산 낭비의 소지가 있고 보상비 집행에 대한 대민 신뢰도 저하로 인해 다수의 소송으로 이어질수 있다. 이에 기존의 보상비 집행업무 프로세스 개선 및 건설CALS 용지보상시스템과 디지털예산회계시스템의 연계를 통해 보상비 집행의 투명성을 확보하고 민원인들에게 대민행정에 대한 신뢰도를 높일 수 있는 방안을 제시하고자 한다.

Domestic construction industry accounts about 15% of Gross Domestic Product(GDP) and Korean government spends approximately 50 trillion won per year for public infrastructure projects. Effective management of public construction projects would result in cost saving and enhance financial stability of the government. In doing so, the government promoted a new budgeting system, Continual Budget Method(CBM) as a part of public project performance enhancement program published in 1999. This research mainly attempted to investigate and analyze the impact of new budgeting in term of cost and schedule performance. Based on the analysis result of n2 projects. The new budgeting system could save project cost by 9.83y. Due to the saving of indirect costs from reduction. Although limited government budget cannot allow all the projects to be excuted with the new budgeting system, the new budgeting system should be more-widely utilized in the public sector because of its proven benefits from this research.

To reduce uncertainties and make rational plans, the presumption of contingency against a failure of projects and an occurrence of unpredictable risks is important with accurate estimations as the work progressing. Therefore, if the presumption of contingency reflecting uncertainties carries out at a decision making point of time, be able to prepare for risks. The purpose of this paper is to present a management process of contingency through the performance analysis of project. In the cost planning phase, this study offers a process which is predictable contingency and predicts the range of fluctuation of the cost, laking an advantage of EVM in construction phase. With reflecting the results from this procedure, this study presents a process, rationally manageable contingency.
