Since 'Act on Private Participation in Infrastructure' were changed in January 2005, BTL(Build-Transfer-Lease) projects of Private Participation in Infrastructure was introduced in the domestic construction market for the purpose of providing public facilities with the public. Selecting the most qualified Promoter should be considered discreetly in BTL projects because BTL projects is for projects with approximately thirty year project life cycle, plan, construction, operating, maintenance and obviously the success of the project totally depends on the capability and role of Promoter. However, score for cost is likely to influence selecting Promoter to take the project. Accordingly, low bid contract with too much competition could decrease the quality of the construction plan and operating plan. Thus, this study did preliminary research and documents on problems of evaluation criteria for selecting Promoter in BTL projects, and proposed improvement factors by doing questionnaire over specialists of each field.

BTL(Build-Transfer-Lease) Project for Education Facilities is contracted as a package which consists of several education facilities and its maintenance period is 20 years. Thus, total cost variation largely depends on the accuracy of the maintenance cost forecasting in the early stage in the life cycle of the BTL Projects. This research develops a method using complete linkage algorithm and branch & bound algorithm to help in finding optimal bundling combination. The result of this research suggests more reasonable and effective forecasting method for the maintenance bundle in BTL projects.

The Build-Transfer-Lease (BTL) projects have rapidly increased under the Government support during recent years. This paper presents the risk analysis of factors affecting BTL projects in the initial phase. This study resulted in 10 significant risk factors influencing on each phase of BTL projects and then factors were grouped into each phase. The sensitivity analysis was also performed to identify risk factors with more significant influence on BTL projects. The results may useful to practitioners in order to cope with risks in initial phase of BTL projects. The paper resulted in the distribution of risks to project parties, thus it can be used as standards for risk assignment to competent authorities and private enterprises of BTL projects.

It requires an interim performance assessment for BTL business of the sewerage rehabilitation which continues from 2005 till now. Means, It is necessary to make an interim performance assessment and an analysis of an business effect of the sewerage rehabilitation BTL projects which still continues, and we presented an improvement method of the new sewerage rehabilitation project in future. This paper has conducted an analysis of the business effect for 3 local government BTL projects which are completed and under operation as of now in Jincheon-Gun, Cheongju-Si and Gangjin-Gun. As a method of business effect analysis, we conducted a business effect of the 3 places using the index set which we previously set for the business effect analysis. The index set in this research was sectionalized to an improvement effect of operating wastewater treatment plant, an benefit effect of the direct cost, an benefit effect of the indirect cost and an environment friendly effect. We, in this paper, conducted an business effect analysis for 3 sewerage rehabilitation BTL projects which are completed or under operation recently as a demonstration, however we judge that an business effect analysis shall be conducted in a stage that a significant time for operation has passed since the completion of the construction in order to induce an actual business effect of the sewerage rehabilitation BTL project.

Build-Transfer-Lease (BTL) was introduced to the domestic construction market in 2005. Now, seven years later, the BTL model is most active for educational facilities. In 2011, 93 educational facility projects entered the maintenance stage. Considering the characteristics of today's BTL projects for educational facilities, the main issues are the initial performance and maintenance of educational facilities and the service-providing status for the 20-year operational management period, in relation to providing safety and convenience to students, the facility users. Seeking a solution, local education offices and departments in charge of BTL under the Ministry of Education, Science, and Technology have been exploring various methods of evaluating operational maintenance performance from various perspectives. For educational facility BTL projects, however, the appropriateness of initial operation performance evaluation, rather than considering the 20-year operational management period, is controversial in regards to sustainability. On this account, performance evaluation items in four areas-operational maintenance evaluation, facility performance status evaluation, maintenance subject evaluation, and sustainable change response evaluation-should be extracted. An indicator of facility performance evaluation is presented in this study through an AHP survey targeting experts, as part of establishing an operation performance evaluation system for educational facility BTL projects.

According to the public information of the Ministry of Education & Human Resources Development, the construction project of educational facilities from 2005 to 2007 will use BTL (Build-Transfer-Lease) contract. Budget of those projects will be the worth over 13 trillion won. In this research, the estimation standards for the public health maintenance expenses are established which is the part of the operation and maintenance cost in the total BTL project cost. Also, a system core module using the developed standard was introduced in this paper. A comparative analyses were conducted with the several possible estimation case to validate the system developed.

To enhance the competition of National power, the investment of SOC is an essential factor for infrastructure construction. The capital for SOC is so gigantic and the national finance is limited, engagement of various subject is necessary. So, Government is promoting the private sector to invest capital in SOC development. Nevertheless the increasement of SOC investment, various problems were issued in selection & operation of BTL. Therefore, to raise the probability of success for BTL project, escalation, unification and specialization of BTL affairs, BTL selection process were suggested in this study.

As the law on the private sector investment in social infrastructure was amended in January of 2005, the government is aggressively promoting BTL projects but many trials and errors and problems are occurring. Especially, the Value-For-Money evaluation conducted by the responsible agencies to judge the appropriateness of the project found there was a conspicuous difference between the computed cost and the final contract sum. Accordingly, this study is aimed to grasp the problems in the current Value-For-Money evaluation and to improve it in order to proceed with BTL projects efficiently. To achieve this, through a relative comparison to the final contract sum, a clear standard for the items of Value-For-Money evaluation was presented and thus, a model that can ensure accuracy in computing the Value-For-Money was established so that a delay in negotiations can be avoided. If the Value-For-Money evaluation established in this study is used in assessing the appropriateness of unit prices for BTL projects for education facilities, a reasonable result can be expected to be drawn in selection and negotiations with contractors, and maintenance and Post-Operation-Evaluation(POE) of education facilities as well.

Since the partly changed 'Private Investment Act for Social Infrastructure Projects' set forth in January 2005, the number of BTL(Build-Transfer-Lease) projects offered to the market has rapidly increased. The scope of BTL projects offered covers not only legally defined facilities but several facilities for the private schools. A BTL project, by definition, is a way of project management that includes the entire process of development such as planning, design, construction and operation over the period of 20-30 years. As a result, various types of risk may happen at each stage of the project and it is extremely important to efficiently control the sensitive factors that affect the risk profiles of the project. The examples of the sensitive factors are construction cost, interest rate, discount rate, lease amount, rental fee, O&M cost and so on. This study examines the characteristics of these sensitivity factors, analyzes their impact on the project feasibility and suggests the alternatives to manage them efficiently.
