The Construction Management(CM) System in Korea is systematized both in name and reality by being prescribed in Construction Industry Act('97) and Construction Management Act('01) through various discussions considering reformation of construction industry structure and enhancement of construction technology competitiveness. Specially in the public construction works, CM Pilot Project is promoted by central government for the activation of CM system introduced for efficiency of public construction project. The promotion of Pilot Project is not only the settlement and activation of CM system but also the process to embody and diversify the CM system. Now we should develop various CM application type such as Owner type, PM type and type for private capital project in doing so. And with this efforts, we could expect that CM system should play an important role to enhance the efficiency of public construction works and should affect private construction sector.

Koran Government introduced BTL(Build-Transfer-Lease) to provide convenience through early supplying infrastructure and plans to invest 8,315million dollar to 84 projects of 15 BTL type involving official residence and railroad. But some of construction company hates to invest BTL projects because of its low earning rate. In addition if we correctively apply project which partly has profitability to BTL, the earnning rate declines more seriously. So this paper presents BTL+BTO model which operates BTL in the non-profitable parts to improve convenience of users and BTO in the profitable parts to improve earning rate. BTL+BTO model based on operate period was presented and its suitability was confirmed by applting 00 region official residence project.

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.

PFI(Private Finance Initiative) Project is carried to expand infrastructure effectively through participation of private investment. From the year 2005, the range is expanded not only industrial infrastructure such as made road, harbors and so on but living infrastructure such as school facilities, environmental facilities. For this reason BTL(Build-Transfer-Lease) system is mainly used in new private finance initiative project but in existing private finance initiative project BTO(Build-Transfer-Operate) system was used. BTL system is operated to judge fitness of private investment and classified into quantitative VFM(Value for Money) and qualitative VFM. In this research the estimation item of qualitative VFM which is hard to deduce the effect is created and after surveying of questionnaire in target of experts, relative importance and weight is established with AHP(Analytic Hierarchy Process). By estimating efficiency and benefit of quantitative VFM and qualitative VFM aspect effectively it is expected to support a rational making decision for operating BTL.

두산건설(주)은 1960년 동산토건으로 시작, 해외공사 및 국내 유수의 시공실적과 함께 지난 반세기에 걸쳐 앞선 기술과 품질로 건설산업을 이끌어 왔다. IMF당시 과감한 구조조정을 단행 하였고, 두산개발, 고려산업개발을 인수합병한 후 외형적인 성장 뿐 아니라 내실경영에 만전을 기하고 있다. 또한 시장환경변화에 대한 중장기 성장동력으로 복합개발사업, SOC민자사업, 도시개발사업 등 디벨로퍼(Developer)형 사업확대를 중점적으로 추진할 계획이며 이 중 복합개발사업은 후발주자로 시장에 진입했지만 지난해 1조3,000억원의 물량을 확보하는 등의 성과를 거둬 앞으로의 사업전망이 밝을 것으로 예상하고 있다. 두산건설(주)은 최근 부산 해운대에 아시아 최고 높이인 80층 주상복합아파트를 분양함으로써 초고층건물 시장에서의 입지를 다지고 있다.

When the new highway is opened, the new highway has alternative or linkage relationship with current highway networks. This change will lead to the different traffic patterns which can also lead to the change of toll revenue in other surrounding highways. This study investigates the change of revenue on the current highway networks caused by the new highway opening under the unified revenue system. Moreover, this study calculates the effectiveness of the revenue fluctuation when the highway system is under controlled by the public or private institution and proposes the meaning of the revenue fluctuation to those institutions. This study also proposes an index of revenue change that could be used to reflect the individual project evaluation and set the priority between multiple projects. Some limitations and future research agenda have also been discussed.

Korean port developments have been mostly made by the central government. With the introduction of the Port Authority system, however, roles and function assignments of the central government in port development have been in change and the Port Authority has to find a solution for inducement of private investment in port development. This paper has examined the current legal system of port developments and then sought the way for inducement of private capital to improve specialty and efficiency of harbor facilities management and development under Port Authority. As the Ministry of Maritime Affairs and fisheries(MMAF) has two types of legal system for inducement of private investment on port developments, the Port Authorities can also have two types of private finance. Private finances by the Port Authorities has some more critical advantages than the one by the central government. It is also required to change the the administrative permissions and concession agreements which MMAF conveyed to private participants in port developments into the concession agreements between Port Authorities and private participants.

The construction supervisors of the public companies are usually responsible for process management, quality management, safety management, and many other various tasks that occur during construction project. Public companies such as Korea Highway Corporation have developed a framework and manual for management and supervision of construction projects. But, there has been the change of business environment such as increase of private investment project and the introduce of construction management system recently. It has been necessary for construction supervisor to streamline the current project management system in the owner's aspect in order to cope with the expected new challenges. Accordingly, this research has been investigated and analyzed the operation system between Korean supervisor and foreign supervisor in their public corporation. This research has suggested the advanced project management in their public corporation. Especially, this study has proposed the construction management manual for supervisors such as inspectors training, supervisors construction manual, and supervisors training road map.
