Development of social overhead capital (SOC) requires huge national finance, and performance issues such as cost-efficiency, safety, and environment have been constantly raised. However, currently each construction client has limited access to its own projects' performance without analytic methodology for industry-level comparisons and benchmarking for improvement. To overcome this problem, this study proposes a comprehensive performance analysis framework for post-evaluation of large-scale construction projects. To this end, this study performed a case study of advanced countries (the U.S., the U.K. and Japan) and consultation with related experts to develop a tailored performance analysis framework for the Post- Construction Evaluation and Management system in Korea. The developed framework covers three categories (project performance, project efficiency, and ripple effect), nine areas (cost, schedule, change, safety, quality, demand, benefit-cost ratio, civil complaint, and defect), and 31 detailed metrics. Using industry-level project performance database and statistical techniques, the proposed framework can be used not only to diagnose excellent and unsatisfactory performance areas for completed construction projects, but also to provide reference data for future similar projects. This study can contribute to the improvement of clients' performance management practices and effectiveness of construction projects.

At the Bank of Korea, capital stock statistics were created by the PIM (perpetual inventory method) with fixed capital formation data. Asset classifications also included 2 categories in residential buildings, 4 non-residential buildings, 14 constructions, 9 transportation equipment, 28 machinery, and 2 intangible fixed assets. It is the Korean government accounting system which is developed much with the field of the national accounts including the valuation, but until 2008 it was consistent with single-entry bookkeeping. Many countries, including Korea, were single-entry bookkeeping, not double-entry bookkeeping which can be aggregated by government accounting standard account. There was no distinction in journaling between revenue and capital expenditure when it was consistent with single-entry bookkeeping. For example, we would like to appropriately divide the past budget accounts and the settlement accounts data that have been spent on dredging into capital expenditure and revenue expenditure. It, then, tries to add the capital expenditure calculated to FCF (fixed capital formation), because revenue expenditure is cost for maintenance etc. This could be a new direction, especially, in the estimation of capital stock by the perpetual inventory method for infrastructure (SOC, social overhead capital). It should also be noted that there are differences not only between capital and income expenditure but also by other factors. How long will this difference be covered by the difference between the 'new series' and 'old series' methodologies? In addition, there is no large difference between two series by the major asset classification level. If this is treated as a round-off error, this is a problem.

As the economy of a country develops, the necessity for social overhead capital such as railroad, highway and other transportation infrastructures becomes an utmost issue as the volume of traffic increases. As the standard of living has been raised the needs for ecological road pavement also increase. As a matter of fact, the concrete and asphalt pavement have been constructed without considering the harmony with nature. The Road Compound pavement is constructed with local soils from optimum mixture proportions that did not contaminate the surroundings and represent the ecological pavement.

This Paper deals with the development of Incheon International Airports and Pusan and Kwangyang Ports as Hub Ports in order to systemize nationwide logistics networks. Now, Korea has core competences in terms of social overhead capital, telecommunication, information technologies, all fields of manufacturing plants, and the other infra-structure. As the environments of North-East Asian countries changes dynamically, at least we should keep up with the situations which require to meet the globalized level of international logistics services in Pusan and Kwangyang Ports to be a competitive Hub Ports in this region.

This paper reviews the achievements of the infrastructure investment policies since around 1990 and identifies policy area in which further efforts should be made. Traditional definition of social overhead capital has implied that the government should be the main, if not sole, supplier of the service. However, many sectors or sub-sectors of infrastructure investment and service allow room for private sector involvement. Expanding the role of the private sector will supplement the resources of the public sector, but more importantly, introduce competition in infrastructure provision. Competition will enhance the efficiency even a particular service remains in the hand public supplier. Private sector involvement, however, raises special problems in Koran context. They are the concentration of the Capital region and regional imbalance; excessive economic powers of large business conglomerator, so-called land problems. We examine each problems in detail and suggests possible solutions.

To provide the basic policy informations for environment-friendly and economical construction of green forest road, forest road density considering for the forest terrain and characteristics was computed. As results, designing the effective forest management and protection, standard forest road density as a social overhead capital (SOC) concept was computed to 8.57 m/ha. Considering as based facilities for forest management, we also optimal forest road density for preparing the sustainable forest management system was computed to 14.01 m/ha.

The Korean government is encouraging positively PIP(private infrastructure project) to relieve financial burden and get the facilities in time. The portion of the PIP has grown rapidly into 15% of the whole SOC(Social Overhead Capital) projects. It is estimated that the growth will continue for the present. However, there are still rising problems on efficiency of the project and productivity, properness of the project scale are pointed against surprising growth. In this study, we analyze underlying problems of private infrastructure investment project and suggest CM Models to relieve the problems. To verify the validity of the suggested models, a survey has been conducted through questionnaires and analyzed the taste of the stakeholder. The owner-support Model is chosen as the practical model to apply in time. By applying the suggested model to PIP, it is possible to enhance the efficiency and productivity of the project.

As the urban development economy is stagnating due to the reduction of the budget for Social Overhead Capital (SOC) and the stabilization policy of the real estate market, there is a steady increase in the interest of domestic construction companies to enter the overseas market. However, domestic construction companies are showing a decline in overseas urban development market as compared with advanced foreign companies having excellent financial management and overseas project management ability. Therefore, it is necessary for domestic companies to select an urban development model that meets the environment and the level of the country of entry, and to establish an advance strategy to manage the risks of overseas business. For this purpose, the factors of entry into the overseas urban development market through the existing research, literature analysis, and FGI were derived, and survey strategy and IPA analysis were conducted to develop strategies for entering the overseas urban development market. As a result, we have established a strategy for private companies to enter the overseas urban development market.

To enlarge the international competition and construction productivity, the domestic construction market attracts the private capital and expands the facility of :iocial Overhead Capital(SOC). However, the application of the business system used at the public project didn't utilize the effect of social overhead capital. It caused problems that parties' business was inefficient and their allotment of the risk was inadequate. This paper presents the course to reorganize the business system which the coincides with the origin aim of the SOC. For the reformation of the supervisor's work scope and business system and the government's overall project management, in other words, this paper proposes the professional organization to replace the superintendence and the formation of optimal business system. This paper confirms the privity of contract among parties of SOC project and parties' work scope and system between relative laws and concession agreement that government made a contract with Special purpose Company (SPC).
