According to Korean Ministry of Land, Transportation and Maritime Affairs, total national SOC(Social Overhead Capital) stock comes up to 500 billion dollars. Until now, although the construction of SOC is more important than the maintenance of them in Korea, it is necessary to introduce of valuation based total asset management concept in nowadays. In this paper describes problems of exsiting data collection method, needs of Information Technology and introduction of RFID/USN(Radio Frequency IDentification/Ubiquitous Sensor Network) in data collection stage.

Infrastructure asset management can be defined as the long term and cost effective management strategy to meet the required service level. In most developed countries, the major motivations of the introduction of asset management are increment in number of assets, extension of maintenance field, accounting approaches of public facilities, performance-based FM(Facility Management), limitations of public funds and public-private partnership, life cycle cost approach, and the development of information technology. This paper discusses the strategic and stepwise methods of introducing infrastructure asset management. Strategic approaches are suggested to develop the practical methods of condition and value assessment of assets, and long-term capital investment plan for optimized decision making(ODM). Required systematic processes are analyzed in terms of resource and technical limitations and detailed implementation plan for each development phases are suggested.

In many developed countries, social infrastructure asset management has become an important issue for the effective operation and management, performance improvement, and providing better quality services. This paper describes infrastructure asset management practices in Korea and in the developed countries. Learning lessons from those countries and improve the asset management practices in Korea is the main theme of this paper. Considering the definition and basic structure of infrastructure asset management, authors have analyzed main concerns regarding infrastructure management, techniques, organizations (systems), and processes. The requirements and considerations are presented to overcome the limitations of current maintenance system. This paper will assist adopting infrastructure asset management in Korea and provide guide for the infrastructure maintenance.

Many of the researchers have tried to enhance the satisfaction of both users and owners of social infrastructures by applying the asset management methodology. This study is to develop more efficient asset management framework for bridge management. Based on various literature review, an asset management procedure for bridge management was suggested, and appropriate practices at each step were given. The suggested procedures include the determination of operation and maintenance strategy, level of service, performance measure, valuation of assets, and decision-makings. In addition, this study suggests an applicable decision-making process for the resource distribution based on the management strategy.

사회기반 시설물들의 노후화로 유지보수 비용이 급격하게 증가하고 있는 선진국뿐만 아니라 국내에서도 시설물을 체계적으로 관리하여 안전사고를 예방하고 유지관리 예산을 절감하고자 하는 관심이 날로 증대하고 있다. 해외의 뉴질랜드, 호주, 캐나다, 미국, 영국 등의 나라에서는 공공시설물 유지관리에 자산개념을 도입하여 관련 법과 제도를 정비하고 대웅적 유지관리방식보다 자산의 가치 중심의 예방적 유지관리로 전환하여 일정 부분 성과를 내고 있다. 국내에서도 시설물을 체계적으로 관리하여 안전사고를 예방하고 유지관리 예산을 절감하고자 하는 관심이 날로 증대하고 있다. 이에 IIMM의 자산관리 업무절차 모델과 국내에서 제시된 KTAM-40을 비교하여 공공시설물 자산관리 정보시스템의 설계방안을 제시하고자 한다.

With the social infrastructure being deteriorated, there is a growing need to introduce the asset management to social infrastructure management in order to increase their value and save budget. Social infrastructure asset management is a new concept of facility management in response to these demands. It is defined as a procedure for collecting and analysing facility maintenance data and for making and practicing an economically optimized management plan. Detailed survey work of asset management business is analyzed in order to derive a strategy for asset management information. The contents of IIMM of New Zealand and the asset management definition of the FHWA of the United States, and representative facility management systems of Korea are analysed. The role between organizations and the relationship between business and organization were analyzed. Information required for asset management and for existing facility management systems is compared with business of asset management. In this thesis, three development strategies are suggested. The first one is to develop core business of asset management while excluding duplicated development. The second one is to divide system's structure into three layers. And the last one is to share information by interfacing asset management systems with existing facility management systems.

Recently, the paradigm of social infrastructure investment has been changed from new construction to maintenance and management. As a consequence, the management and maintenance system of existing highway facilities needed an innovation involving the concept of asset management. This paper discusses the new facility management system suitable to local highway agencies. The new system incorporates asset management concept so that it can analyze the network level facility management solution and it can also improve the budget efficiency for local government. This paper also presents systematic method to integrate various facilities for management system.

국도는 사회간접자본 중 하나로서 지속적으로 관리되어야 그 기능을 발휘할 수 있는 국가의 중요한 자산이다. 지금까지는 국도를 포장관리시스템이라는 체계로 관리하여왔다. 이 포장관리시스템은 시설물유지관리차원에서 사회기반시설을 관리하는 것으로서 주로 관리자 관점에서 공학적 판단을 기준으로 최소의 비용으로 공용수명을 최대화하는 모델이다. 그러나 경제발전으로 국민의 소득수준이 올라감에 따라 기본적인 욕구가 해결되어 이제는 납세자로서 국민의 동의는 국가의 정책을 결정하는데 중요한 변수로 작용하기 시작했다. 따라서 사용자 관점의 평가는 이러한 요구의 수준을 측정할 수 있는 중요한 척도가 되었으며 이에 기반한 LoS(Level of Service, 서비스 수준)라는 지수를 시설물 자산관리에 활용하려는 여러 가지 시도가 있다. 이 논문에서는 기존 국도포장관리시스템의 정보모델과 KTAM-40(Korea Total Asset Management-40)이라는 자산관리 정보모델을 비교하여 LoS의 필요성과 도로포장자산관리에서 LoS가 사용자 관점을 반영하는 방식을 조명해 이의 장점을 밝히고자 한다.

Management of social infrastructure has been advanced from facility management (FM) to asset management (AM), which adopts the aggressive and proactive methods in predicting the deterioration of infrastructure, prevents failures, and eventually saves maintenance cost. Infrastructure asset management is not a simple engineering technique, but it is a new paradigm evolved from facility management practices. To implement the infrastructure asset management successfully, organizational reform is very important. This paper suggests critical success factors and key performance indicators to implement the infrastructure asset management for facility managers of government owned social infrastructures such as roads and bridges. Reorganizing the facility management group requires new vision, objectives, strategies for the paradigm-changing asset management. This paper uses Balanced Score Card (BSC) which is a proven method in measuring and setting new objectives for an organization. Once the performance indicators are reviewed repeatedly by facility managers through experts workshops, developed BSC can be used in practice. This paper discusses the development of robust BSC scoring method through in depth literature reviews and investigation of asset management practices of domestic and international cases.

As the social infrastructure becomes deteriorated, its maintenance cost has been increased rapidly. There are growing needs to manage facilities systematically to reduce this kind of maintenance budget, and furthermore to avoid safety accidents in Korea. Asset management is widely used in New Zealand, the United States, Great Britain to manage their social facilities. In these countries, standardized information model and its system are developed and in service for asset management. There are several researches on asset management of social infrastructure in Korea, and the KTAM-40 work procedure is one of the main results for these researches. In this paper, the IIMM of New Zealand and the KTAM-40 of Korea, were surveyed to develop a business architecture of the highway asset management system. A new business architecture for the highway asset management system is proposed based on the KTAM-40 work procedure: First, the organization and its role for the highway asset management are defined. Second, business functions of the highway asset management are classified. Third, the highway asset management functions and the flow of information are defined. In the last section, differences between the newly designed architecture and the other systems' architecture is reviewed.
