The BTL project, 4 years since its operation, has benchmarked the PFI Project in Japan and has been introduced. Given the evaluation step to select a preferred bidder, in a technological factor, the basic plans are corrected and complemented, whereas in a price factor, the low price bidding system is being enforced. There is concern that how to select preferred bidders and how to operate project costs during operation and management period may be problematic. Thus, in this study, using the Analytic Hierarchy Process, the method of deciding the pribrity to select preferred bidders in an early stage of the project and the evaluation model to evaluate the validity of BTL project expenses in process of project enforcement are established. Targeting the group. composed of experts who have experiences in the BTL project. Then, the levelling of evaluation factors and grouping have been carried out as following: LCC analysis and disbursement for government including two more detailed factors.

According to revision of Construction Technology Management Act (2005), the government ordering construction which cost is more than 10billion won should investigate the value engineering(VE) of a construction. In this sense, the government actively promote plans in 2008 after identifying the examining standards of the investigation on the VE(2007). It is substantial issue to introduce Pre-Qualification(PQ) in oder to restrain unlicensed VE consulting companies or VE consultants. This system will contribute to the quality and the settlement of the value engineering in our country. The reason why the Korea VE Society founded in 2006 is one of the afore-mentioned reasons. Therefore, we try to establish the value engineering of Build-Transfer-Lease Scheme by providing the practical application of construction value engineering and definite procedures through the example of Andong Culture and Art Center's research in one of the various construction fields.

The 10,876 school buildings(year 2006) including elementary, junior high and high schools have been operated and the number of school buildings will increase with BTL(Build Transfer Lease) projects. However, as population is expected to decrease rapidly with low birth rate, it needs to pay more attention to managing existing school buildings. The present maintenance and management system is not being operating with regular plans but with making repairs when if problem happens. Therefore, in this study I will propose a new maintenance and management system which will improve the process of maintenance and management works and reflect the needs of related officials in charge of with analyzing a present maintenance and management system through making research into documents and questionnaires. It enables to simplify maintenance and management work, to manage budget with transparency and to make better communication between each work so that it promotes efficiency of maintenance and management work.

The purpose of this research is to identify problems and solutions of domestic Life Cycle Cost analysis in BTL(Build-Transfer-Lease), a PFI(Private Finance Initiatives) project. It is expected BTL would be quite effective delivery method for public construction introducing the private's major capital investments and technologies, and obviously LCC analysis is becoming more important factor for success of BTL projects. Nevertheless, there are still some complicated issues in LCC analysis, a technique for selecting the optimal VE(Value Engineering) proposals and estimating OM&R (Operation, Maintenance, & Repair) cost of the buildings, and has been applied limitedly. This research mainly focuses on educational facility, as most frequently delivered by BTL currently, especially with two levels (Alternative LCC and Building LCC) , which is occupied main potion in BTL project. In addition, it identifies four main problems and suggests their solutions through case studies focusing six major factors (WBS, Repair Information, Life Cycle, Time value of money, Repair Information Database, LCC Model) from three projects. Advanced development of this research requires closer partnership between the private / public sectors, and their long term strategies.

This study is a LCC case analysis on the school one of the BTL projects which is constructed by private organizations and rented to government. According to the RFP to make out documents, it is performed the case analysis based on the results of LCC calculation about maintenance & conservation costs; repairing costs and replacement costs. It is analyzed LCC on maintenance & conservation costs for 20 years(rent period) and 65 years(life cycle). As a result of LCC analysis, about more than 50% of total LCC are architectural works and the rest of them are machinery works, electric works, and civil works in the order. And it is also suggested some problems and their solutions to perform LCC analysis on the current BTL projects of school.

The purpose of this study is to improve project performance analysis indicators for BTL sewer rehabilitation projects. Among the assessment indicators for BTL sewer rehabilitation projects, an infiltration assessment indicator is given a high score of 17.5 points as a single assessment item. This infiltration assessment indicator is assessed focusing on the amount of infiltration, and presently calculated according to 'Nighttime Domestic Flow Evaluation' method. However, this assessment indicator's failure to reflect the geological features of Jeju region is emerging as a problem in the operational stage. Thus, this study intended to compare and analyze the calculation result depending on the assessment indicators and the actual amount of infiltration, centering on Jeju region. To this end, this study analyzed the amount of infiltration in five areas of Jeju Province calculated according to 'Nighttime Domestic Flow Evaluation' method. Also, a complete enumeration survey was carried out about the conditions for actual infiltration occurrence. According to the results of this survey, ground water level is distributed lower than the level of sewer pipes. The results of a sewer pipe function test show there was no infiltration occurrence caused by sewer pipe defect. So, it is concluded that 'Nighttime Domestic Flow Evaluation' method, which is utilized for the current assessment indicator, is not appropriate to apply to Jeju region, and it is thought that there is a need to establish infiltration criteria specialized for Jeju region.

The aim of this research is to suggest the model of reconstruction and remodelling of S high school of broadcast for converting into a specialized one in the section of broadcast industry. The method of reconstruction of the laboratories by each department is as follows. First, the names of laboratories, ground plans, and perspective drawings are designed according to the principle of constructionism. Second, each department is recommended to install 7 laboratories. For the department of broadcasting facilities, a laboratory of processing broadcasting machines, a laboratory of broadcasting machines, and a laboratory of screen picture machines are needed. For the department of broadcasting, electricity, and communication, a laboratory of image and sound edition, a laboratory of broadcasting and communication, a laboratory of broadcasting system, and a laboratory of stage illumination. For the department of broadcasting stage construction, a laboratory of broadcasting stage building, a laboratory of broadcasting stage design, a laboratory of broadcasting stage decoration and etc. Third, an office room is designed by department in the form of seminar room and places for practice is formed by department to be a laboratory. Fourth, a room for industrial-educational cooperation is installed by department, by which education of industrial-educational cooperation is carried out harmoniously. And one example of a remodeled laboratory by one department is shown with laboratory name, ground plan, perspective drawing, and running method. Especially employment of teachers working both school and business, professional club which is concerned with broadcasting technique, and attraction of enterprise in school is suggested as important elements to manage broadcasting laboratories efficiently. Finally, it is desirable for us to attract private capital, that is, Build-Transfer-Lease(BTL) because much budget is required for purchasing the broadcasting equipments and remodelling the laboratories to succeed as specialized high school on broadcasting section.
