2005년 1월 민간투자법의 개정에 따라 전국적으로 44개 국공립 시설 뿐 아니라 사립대학을 중심으로 BTL사업의 발주가 급증하고 있다. 그러나 BTL사업은 시설의 기획, 설계, 시공, 운영 및 관리까지 포함하여 20여년 이상의 프로젝트 관리 과정을 대상으로 하는 포괄적 사업방식이다. 따라서 각 단계별로 다양한 리스크 인자들이 발생하게 된다. 그러나 사업제안단계에서 재무적 리스크를 정량적으로 분석할 수 있는 민감요인은 공사비, 차입금리, 할인율, 부대사업 임대료, 운영비용 등이 있다. 본 연구에서는 BTL사업 제안단계에서 사업에 영향을 미치는 리스크 요인들의 특성을 고찰하고 이 요인들이 사업성에 미치는 영향도를 분석하고 이에 대한 대응방안을 제시하는 것을 목적으로 한다.

민간투자사업의 자본구조는 사업시행자가 출자한 자기자본과 대출금융기관으로부터 조달한 타인자본으로 구성된다. 민간투자사업 기본계획에서는 사업시행자의 최소 자기자본비율을 25%로 규정하고 있으며, 일반적으로 정부와 사업시행자 간의 실시협약을 통하여 자본구조를 결정하게 된다. 그러나 민간투자사업의 자본구조는 사업의 수익률과 재무적 안정성을 결정하는 중요한 기준이기 때문에 자금조달계획 수립 시 자본구조에 따른 수익률의 변동성을 파악하고 적정 수익률과 재무적 안정성을 고려하여 자본구조를 최적화할 필요가 있다. 본 연구는 민간투자사업의 수익률과 재무적 안정성을 동시에 극대화할 수 있도록 자본구조를 최적화하기 위한 방법론을 제시하는데 그 목적이 있다. 이를 위하여 기존 민간투자사업들의 자본구조를 고찰하고 민간투자사업 재무모델을 분석하였다. 재무분석을 바탕으로 최적 자본구조를 결정하기 위해 효용함수 개념과 다목적 유전자 알고리즘을 이용한 자본구조 최적화모델을 제시하였다. 제시된 최적화 모델을 인천공항철도 민간투자사업에 적용하여 최적 자본구조를 도출하였고 민감도 분석과 시나리오 분석을 통해 그 활용성을 검증하였다. 사례분석 결과, 최적 자기자본비율은 실시협약에서 결정된 30%보다 낮은 22.3%에서 결정되었으며 이는 자기자본비율을 더 낮추어도 수익률과 재무적 안정성을 유지할 수 있다는 것을 시사한다. 본 연구는 수익률과 재무적 안정성을 동시에 고려하여 최적 자본구조를 결정함으로써 민간투자사업의 사업시행자에 적합한 자본구성과 자금조달을 위한 합리적인 의사판단 기준을 제시하였으며 사업시행자의 수익률 향상에 기여할 것으로 기대된다.

Recently, BIM has been widely applying in civil engineering projects centering on the private construction industry in order to establish self guidelines for spreading in practice. However, most BIM technologies and software are based on the architectural projects. In these environments, it is not easy to apply the BIM to a infrastructure field. Even BIM standards with IFC (Industry Foundation Classes) are also focusing on architectural projects. Especially, both private and public sectors do not know about how BIM delivery system should be performed, and how such deliverable should be submitted to the government yet. Thus, we need to analyze an application level of BIM S/W (Software) in real projects and verify their interoperability. Besides, since there are not any common standards that can exchange IFC models for civil engineering projects, we have many issues in converting as-built infrastructure models into IFC and delivering their design documents to the government. Accordingly, this study aims to perform a BIM process with commercial software for real road project after a detailed design process is finished and verify interoperability between diverse BIM software for securing BIM data reliability.

This paper aims to suggest a validity analysis model that would be helpful for local governments considering u-City construction projects and a methodology for them to promote build-transfer-lease (BTL) u-City projects. This methodology mainly uses quantitative and qualitative analysis based on the Value For Money (VFM) designed by the Public and Private Infrastructure Investment Management Center (PIMAC) under the Korea Development Institute (KDI). BTL projects requires a large amount of capital and involves long-term investments. Therefore, multi-faceted validity analysis is required for the success of a project. This study will enumerate various factors to be considered in the pre-analysis of validity of BTL projects and suggest a methodology to verify them. A case study of a BTL project promoted by Ansan City assisted in designing this study in detail.

As a leading nation of ubiquitous technology, South Korea has been promoting u-City pilot projects throughout the country. According to 'Fundamental Construction Law of u-City,' u-City projects are classified into old-town and new-town types. However, most projects have focused only on the new-town type. Pushing forward large-scale land development projects, Korea Land and Housing Corporation (LH Co.) under Ministry of Land Transport and Maritime Affairs (MLTM) has gained a development profit out of the u-City infrastructure and then donated the infrastructure to a local government without making any plan for operations. In the process of u-City pilot projects, old-towns have been relatively ignored and various of unexpected problems have emerged. Building the u-City of an old-town is not easy due to many constraints such as huge initial investment, long validity and verification procedures, lack of useful services for citizens, lack of professional outsourcing methods for business promotion, high operating costs of the integrated control center, inadequate law related, insufficient institutional requirements and so on. This paper introduces a case study on u-City development for an old-town, Ansan City, as a private investment project. The case will help boost u-City projects for old-towns by solving their problems and providing an effective operational mechanism. As the first BTL (Build-Transfer-Lease) project for constructing u-City, 'Broadband Information Network Development Project' of Ansan City will provide a reference model of expanding u-City projects for other cities.

It is no news that Nigeria's infrastructure challenge is enormous. In the global ranking, Nigeria ranked low in quantity and quality of its infrastructural provision which has a great impact on the ease of business transaction. Low investments in transportation have brought about the current infrastructural deficit. Recently, the Nigerian government has made effort to address at least to some extent the infrastructural deficit through Public-Private Partnership, but this has not yielded the desired result. Moreover, the sustainability issues relating to railway projects such as, emissions, noise pollution, ecosystem, and other environmental issues calls for urgent attention. Hence, this necessitated consideration on sustainability appraisal for the Chinese rail project in Nigeria. This study reviews sustainability of railway projects built by the Chinese firm in Nigeria with particular emphasis on the environmental and social impact of these projects. The study further identified issues and challenges in project implementation with a particular focus on civil dialogue and community engagements. A detailed literature search was conducted on railway projects and infrastructure by systematically reviewing selected published articles.The analysis of the selected articles identified sustainability issues and potential for improvement of Chinese railway projects and how they contribute to or inhibit competitiveness in the Nigerian railway market. From the literature searched, some of the projects constructed by Chinese firm revealed that there is economic and social impact of railway projects delivered by the Chinese firm in terms of capacity development and knowledge transfer potentiality. For instance, in the just concluded Lagos-Ibadan railway projects, the study gathered that the project brought about 5000 jobs and local staff were trained by the Chinese company, this will boost man power and local content capability. Also, it will significantly improve Nigeria's infrastructure and boost its economic development. The study suggests that Nigerian government should ensure and provide an enabling environment that is conducive for investment on the continent. Peace, improved security, and decent governance are the best conditions for sustainable transportation growth.
