Highly advanced technologies are being adopted into the domestic construction industry in accordance with rapidly changing global construction industry in the 21st century. Value Engineering methodologies have often been discussed but not yet settled in the country. This research, therefore, aims to provide a useful guide to utilizing design Value Engineering in Build Transfer Lease. 1. Questionnaires had been conducted, answered by those in the field. 2. Questionnaires were in regard to the obstacles in the application of design Value Engineering and activation schemes. 3. Five standards were provided to be chosen according to the degree of influence from each factor, whose answers were technically analyzed by a statistical program afterward. 4. Four obstacles classified in this method were approached systematically to analyze the problems. 5. Efficient Activation schemes have been suggested after various analyses in a variety of aspects.

본고에서는 먼저 재개발사업, 최저가낙찰제 확대, 임대형민간투자사업(BTL), 대규모 개발사업 등 2006년 건설산업 및 건설경기에 영향을 미친 주요변수들의 움직임을 중심으로 건설동향을 파악하였다. 그리고 각각의 변수들이 2007년에는 어떤 모습으로 전개될 것인지를 중심으로 2007년 건설경기를 전망하였다. 아울러 2006년 시멘트를 비롯한 주요 건설자재의 동향과 더불어 2007년 예상되는 국내 건설경기가 시멘트업계에 미칠 영향에 대해서 개괄적으로 살펴보았다.

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.

In case of the BTL project for current educational faculties, the proper standards to analyze those said educational standards lack, so it is very difficult to conduct an exact analysis and those improper standards are problematic when proper management and maintenance costs are calculated. In case of such educational facilities, as students have to use them safely for a long time and the quantity of their activities and the status of their physical growth based on individual classes, as well as the features for use by facility and the regional characteristics are different, other standards for maintenance and management must be considered unlike an apartment house. Thus, in this study, to set up the standards considering the features of educational facilities, the maintenance and management level suitable for educational facilities is presented by comparing and analysing that required to maintain and manage an apartment house, targeting the experts specializing management of educational facilities.

민간 주도형 사회간접자본 (social overhead capital :SOC) 사업은 BOT(build-operate-transfer)를 비롯하여 대상 프로젝트의 정부 정책 등의 여러 환경의 변경에 따라 다양하게 변형되어 적용되어 BTL(build-lease-transfer), BOO (build-own-operate)등의 여러 기법들을 사용된다. 민간 SOC 사업은 프로 젝트의 규모와 장기에 걸친 공사의 불확실성 때문에 프로젝트의 경제성 분석을 하는 것은 복잡하다. 일반적으로 사용하고 있는 현금흐름 할인모형(discount cash flow model; DCF)은 미래의 불확실성 변수들을 적절히 반영하지 못한다는 한계점을 가지고 있지만 현실적으로 많이 쓰이고 있는 방식이다. 본 논문은 옵션기반모형에 근거한, BOT-옵션가치평가(BOT-OV)모형을 국내 민간 SOC 사업의 경제성 분석을 위해 적용한다. BOT-OV모형을 적용하는 것이 기존 순현재가치(net present value; NPV)방식을 통하여 프로젝트 가치 평가 할 때보다 더 정밀한 경제적 타당성 평가를 할 수 있다는 것을 확인하여 기존의 NPV 평가방식의 방법을 대체할 수 있는 가능성을 확인하는데 의의가 있다고 할 수 있다.

The use of school should not be limited to student education any longer but be extended for attaining social benefits. For this reason, school should play central roles not only in education but also in childcare, welfare, culture, physical education, etc. In order for school to accommodate various new functions, it is essential to promote the mixed-uses of school facilities, and this process requires the involvement of private capitals for early achievement of social benefits from school facilities. Thus, this study purposed to examine the necessity of the multiple uses of school facilities through the investment of private capitals, to diagnose the adequacy of build-transfer-lease (BTL) applied currently to the multiple uses of school facilities, and to find obstacles to the activation of private sector investment and suggest solutions for the obstacles. In particular, this study aimed at proposing plans to enhance the efficiency of private sector investment and activate private sector investment projects by suggesting how to promote the multiple uses of school facilities in consideration of profitability for private investors.

Ministry of Environment has been promoting BTL business of the sewer rehabilitation which continues from 2005 up to now. Sewer rehabilitation is classified into three parts : wastewater pipe rehabilitation, rainwater pipe rehabilitation and drainage equipment rehabilitation. Drainage equipment rehabilitation is that drainage pipe connects wastewater pipe directly without water-purifier. In the drainage equipment construction, it is inevitable to have the damage of ground structures(wall, gate and U drain, etc) when an open excavation method is used. Therefore it is necessary to develop non-excavation method to connect drainage pipe and wastewater pipe like jacking method to avoid the damage of ground structure. This paper has conducted an analysis of the non-excavation method using a boring machine attached to backhoe, which is issued the verification certificate of environmental technology according to the Development of and Support for Environmental Technology Act, article.7. The index set in this analysis was sectionalized to the condition of construction, the grade of drainage pipe, the size of excavated hole, the amount of waste cement concrete and asphalt concrete and the benefit effect compared to open excavation method.

The private investment on the SOC facilities is a worldwide tendency since it can supplement the insufficient investment of public finance in the construction of infrastructures. Alter the formulation of private investment law, private sector's investment on roads, harbors and environmental facilities are being progressed considerably. However, railway construction by private sector is not active comparing to the former areas because of huge investment for construction but relatively low and unpredictable benefit in operation. This paper reviews the financial, social and institutional aspects on the private investment for SOC projects, especially railway projects. Also, this paper tries to find the desirable way to expedite the private investment on railway project,. Conclusively, the paper propose that the private sector in railway projects is better constituted with financial investor and the private financing could be. activated and settled if a stable minimum benefit on their investment being ensured institutionally, for example, by BTL.

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.
