The domestic CM business market has continued to grow, but its size is relatively small yet in comparison with the total size of the domestic construction industry. Evaluation of CM projects was conducted through questionnaire surveys. Both clients and CM firms showed positive satisfaction levels. Nevertheless, the clients' satisfaction levels were relatively low in safety management, cost management, and document and information management. Superior areas of CM tasks were time management and recovery scheduling, quality control and technical instruction, and design value engineering. On the other hand, inferior areas of CM tasks were claim analysis and dispute resolution, cost estimation, and life cycle costing. Both entities have agreed with the positive effects of CM involvement in terms of cost saving, time reduction, quality improvement, and safety incidents prevention to at least 0~5% extent.

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.

Construction manager must consider the possibility on the failure of the project in advance and the contingency to provide against the situation, those of which is a dangerous condition not to predict. If they have a quick decision without understanding the contingency, the over-cost in the total cost would be continuously accumulated, and be a barrier at a project going in progress. A various risk could not be coped with at a time to decide either going or sloping the project until the contingency is applied from the first step to progress the project. But a case to apply the contingency to the construction for the investment or the analysis of the project is a little. The process to evaluate it is also absent. The propose of this paper is the followed ; To establish the total cost including the risk first of all, devide into plus or minus factor of the cost, and then the process to calculate the contingency must be suggested by the regression analysis.

This study aims to introduce "Street-Housing" Redevelopment Projects adopted by the revision of regulations in 2012 and promote them by surveying residents' needs. The objectives of the street-housing redevelopment projects are to maintain existing street systems and redevelop housing by small units, as an alternative to the large-scale housing redevelopment by the expropriation. Residents, however, do not seem to support the new projects since they are satisfied with their current housing, have difficulty in raising funds, and are uncertain about proceeding with the pre-arranged. Despite these barriers, residents may support the projects if project charges can be lowered by the reduction in each resident's share and the increase in supporting funds. This study proposes new practical methods for realizing the projects: choice of an appropriate site, engaging for resident's participation in projects, reduction in project charges, and removal of barriers to co-operative development. etc.

This paper analyzes problems related to total cost changes in private investment projects, and then proposes an improvement measure for the control of cost changes within the framework of the project management, contract, human resource, project communication, cost, and time management. From the viewpoint of contract management, the basis of cost change ought to be cleared up with standardization of related provisions in the concession agreement, and potentiality of change ought to be excluded with prescription of the private investor's leading role from the design phase. Regarding human resource management, this paper proposes a standard work flow granting much sovereign rights to private parts by putting restriction on work scopes of the entrusted authority of government, and transferring the rights of assignment, contract, and control about the responsible supervisor to the concessionaire. With regard to project communication management the notification of changes on drawings and technical documents ought to be automated and the realtime database ought to be established with DMIS (Drawings & Documents Management Information System). From the cost management point of view, this thesis integrates the control of cost-change-approved items and disapproved items to one cost breakdown system, and then harmonizes the actual progress with EVMS in time management.

Public institutions recognize the importance of cost management from the planning stage but they do not have an organized construction cost estimation and management system. Thus, at the stage of planning a new public construction project and estimating the cost, those in charge of budgeting estimate construction cost based on existing data and experiences, compare construction cost estimated after the basic design stage and the execution design stage with budgets, and then decide whether to continue the project or change the design according to the budgets. Therefore, we would develop the cost prediction model through regression analysis that can predict construction cost in Schematic Design Phase of the Public Multi-Family housing. Accordingly, if public institutions have a construction cost prediction model and management system that can estimate the optimum construction cost, they can make and execute budgets in a more efficient way than they do at present.

통신사업은 일반 제조업에 비해 기간산업인 동시에 네트워크 산업으로서의 특성을 갖고 발달해왔다. 또한 통신산업은 현지의 시설을 기반으로 서비스가 전개되는 특성을 가지고 갖는다. 따라서, 전통적으로 국가별 독점사업자에 의해 발전해 왔으며, 사업허가 및 영업활동과 관련하여 규제당국의 역할 및 영향이 절대적이었다. 이러한 특성 및 과거의 방식에 비추어 최근의 통신사업 글로벌화 움직임은 기존의 사업체제를 크게 뒤흔드는 것이라 할 수 있다. 따라서, 최근 들어 매우 복잡한 양상으로 전개되고 있는 이 부문의 글로벌화 움직임을 올바로 파악하는 것은 통신사업자의 향후 전략수립을 위해서 필수적일 뿐만 아니라 통신부문의 특성이나 중요성에 비추어 기업활동의 글로벌화 및 글로벌전략 연구에 있어서도 의미 있는 일이라 생각된다. 이에 본 논문은 통신사업 글로벌화의 전개방향 및 해외사업자의 전략에 관한 종합적인 고찰과 분석을 통신사업 글로벌화의 특성을 파악·제시하며, 나아가 글로벌화와 관련하여 통신사업의 향후 발전방향에 대한 전망을 제시하고 있다.

Domestic dominant method in subcontract cost estimate for comprehensive program management is estimation by referencing similar cases or relying on the experience and expertise of the engaged. However, this method is not reliable due to lack of accuracy, making it harder for clients to plan and budget the program. Since budget itself is roughly estimated, it becomes a source of cost rise in the course of management due to design modifications. Therefore, the client and service providers shall calculate more accurate service cost by applying objective and scientific method in order to minimize cost rise and cost related dispute. Traditional cases, in estimating program management cost, took Top-Down approach based on precedents and experience. On the contrary, this study will categorize management structure into phases and activities, issue WBS for each phase to estimated schedule and cost for each code, and take Bottom-UP approach. By taking this approach named ICEP (Integrated Cost Estimate based on Project), Set project typical model will be developed for service cost estimating, calculate cost by applying project-specific factors. Also, by analyzing progress data and allocated management cost to complement them, more efficient construction management will take shape based on program management cost standards which reflect project-specific features.
