The expressway is a key area of road networks for national industry, economics and social development. In addition, the number of lines are increasing continuously. Recently, road management policy have shown a paradigm shift to safe road, low-carbon and green etc. Nevertheless, the road condition has deteriorated dramatically by fatigue cracking, thermal cracking and weather impact. On the other hand, the budgets for highway maintenance have shrunk dramatically. In this study, an effective pavement management and maintenance process was developed to extend the pavement serviceability and pavement life to overcome the rack of budgets.

For a successful construction project not only construction engineering and project management technology but also economic evaluation technique is required. Design and construction technologies are necessary to receive a project order. However, construction management technology which can be apply from the project initial phase to the project operation and management phase is required to create a benefit from the project. Construction management technology is one of the effective factors for project success. Economical and efficient cost management from the planning phase influences the project success. This study investigated cost flow and cost factors of domestic Sewage Treatment Plant project for systematic analysis of cost items following the entire project phase. Particularly, data modeling based on domestic Sewage Treatment Equipment maintenance cost DB was performed, and maintenance cost estimation trend line is suggested using Monte carlo Simulation Method to decrease uncertainty of actual results DB and for feasibility study.

최근 일본에서는 ESCO사업에 PFI법을 새로이 적용하고 있다. 성과배분제, 성과보증제에 이어 이 제도를 적용할 경우, 국가 및 공공기관을 대상으로 하는 ESCO사업의 확대 및 자금조달이 한층 유리해질 전망이다. 지난 99년 제정된 PFI(Private Finance Initiative)법(민간자금 등의 활용에 의한 공공시설 등의 정비 등의 촉진에 관한 법률)에 근거한 사업은 ''공공시설 등''에 있어서 건설, 유지관리 운영 등을 민간의 자금, 경영능력 및 기술적 능력을 활용하는 사업방법으로 사업 전체의 리스크관리가 효율적으로 행해지는 것과 설게$\cdot$시공$\cdot$유지관리$\cdot$운영의 전부 또는 일부를 일체적으로 취급하는 것에 의해 사업비용의 절감이 기대되며 질 높은 서비스의 제공이 가능한 제도이다. 이것과 매우 유사한 개념을 가지고 있는 것이 성과보증제에 의한 ESCO사업이다. 민간사업자인 ESCO사업자가 자금을 조달하고 에너지절약 개수공사에 따른 설계$\cdot$시공$\cdot$, 운전$\cdot$유지관리, 계측$\cdot$검증, 에너지절감 보증 등의 서비스를 제공하며, 광열수도비 및 운전$\cdot$유지관리비의 절감분으로 모든 투자와 ESCO사업자의 경비를 지불한다. 또 에너지절감 및 공공의 이익보증을 포함한 퍼포먼스계약이라고 하는 형태를 취하는 것으로 공공 이익의 최대화를 도모함과 동시에 금융기관의 투자 리스크에 관한 우려를 회피할 수도 있다. 또 PFI법 특유의 법제상, 재정상의 조치와 재정상 및 금융상의 지원이라는 배려에 있다. 예를 들면, 국고채무부담행위의 설정, 행정재산 사용료의 무상화 또는 감면, 프로젝트 파이낸싱 등에 의한 자금조달을 고려할 경우에 있어서 담보권의 설정 등에 관한 제도를 합리적으로 정비하는 것이 가능하게 된다. 그 내용의 대강을 살펴본다.

As time goes by, educational facilities have become superannuated and damaged; therefore, performance and safety of buildings have been decreased. It causes the decrease of service quality and deterioration of educational environment. In order to protect facilities from serious damages and deterioration, a consistent maintenance and repair program is required. The educational facilities can keep the good educational environments and also make better environments through the program. This study is made by investigating and analyzing the maintenance data which was collected from fifty schools in Asan area, Chungchengnam-do in order to derive foundation data for the efficient educational environment maintenance program.

The purpose of this study is to estimate and analyze the optimum economic life of office buildings in consideration of their LCC (Life Cycle Cost), and thereby, explore the ways to manage the outlived office buildings economically. In estimating the economic life, initial investment cost and maintenance cost are taken into due consideration. For this study, those office buildings in Yeouido and Mapo region were sampled. The surveyed details were reduced to unit area to calculate a unit value, and then, their optimum economic life was estimated using LCC. Five alternatives for management of outlived office buildings were compared in terms of reconstruction or rehabilitation cost.

The objective of this research is to develop an assesment system for BTL Project. A new method for the prediction of construction and maintenance cost in the educational facilities has been considered and under development by the authors. This paper explains the current BTL assesment method used by most local district office of education and lists its potential problems. Main conceptual modules in the new Assesment System are shown in this paper. Also, viable results of each module are discussed in this paper.

This paper describes th on-line maintenance system with integrated graphic environment for building electrical equipments. This system is based on the pre-defined troubleshoot knowledgebase with maintenance information. And this system utilizes the database and knowledgebase for the diagnosis of facility and runs on the operator's requirement and response. The operator is possible of a detailed observation, an early detection of abnormal state, a properly operation and a rapidly arrangement of electrical equipments. Especially, this system is developed using the maintenance of equipments, if needed, be operated by non-expertise.
