Due to the rapid civilization, the need for social facilities is increasing. When these facilities controlled by the integrated facility management system (GIS), various adverse situations such as emergencies, inconvenience of the public and duplication of construction cost can be improved. In this study, the types of information for GIS which may be needed by the facility management agencies are investigated and analyzed. Based on this information, major components for the integrated facility management system including standard format of digital map, basemap scales, and basemap management methods are established.

BIM (Building Information Modeling) is a new paradigm that includes construction life-cycle, and BIM has become mandatory regulation according to the Public Procurement Service since 2016, which accelerates its application. BIM is now expand from architectural field to infrastructure industry. Through pilot projects, BIM has been challenged with verification process. This trend has affected to maintenance and operation (M&O) phase of construction life-cycle. Advanced country has already published their research and result with feasibility study and guidelines. In this paper, we conduct the feasibility study to adopt BIM-based infrastructure management system. Bridges and tunnels were selected as application target, and benefit/cost ratio were used. The result shows that BIM-based infrastructure management system is feasible when the level of detail is more than "Medium" in bridge, and "High" in tunnel.

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.

It is important to estimate the future maintenance budget of all SOC infrastructure at the national strategic level. In this study, Based on a currently available statistics data, we predicted future maintenance investment for all SOC infrastructure in Korea. We have studied the applicable prediction models, and we developed the prediction models that can calculated the future maintenance cost by a real expenditure date. The subjects of facilities are bridges, tunnels, pavements, harbors, dams, airports, water supply, rivers and port. As a result of total estimated cost, eight types of SOC infrastructures are about 23 trillion won for the next 10years, and the most expensive facilities are road pavements and bridges.

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.

본 연구는 효과적 생애주기 지원을 위한 사회기반시설물의 3차원 기반 정보모델의 활용방안에 대해 기술하였다. 3차원 기반 정보모델은 형상 정보뿐만 아니라 각 구성요소의 속성정보도 포함하고 있어야 하며, 의사결정 지원을 위한 엔지니어링 문서정보와도 연계 가능해야 한다. 이를 위하여 본 연구에서는 국제표준 데이터 모델링 도구인 IFC를 도로시설물에 적용하기 위한 확장방안을 제시하였고, XML을 이용한 엔지니어링 문서와의 통합연계 방안을 통해 사회기반시설의 효과적 생애주기 지원 전략을 제시하였다. 또한, 이를 활용한 구조해석 모델의 생성, GIS와의 연계 방안 도출의 실사례 구현을 통해 응용 도메인으로의 활용 가능성을 확인하였다.

This study aims to investigate basic requirements for adopting the Building Information Modeling(BIM) technology to management of civil infrastructures. The state of the art on BIM guidelines developed major countries was investigated, and a common framework of the guideline contents was built in order to categorize the requirements. In addition, it was investigated that the point of view on the facility management in the BIM guidelines showed different from the traditional civil infrastructure domain. On the basis of the investigation results, this paper proposed the core requirements categorized into three respects: development of application models, standardization, modification of regulations.

최근 건설 산업의 패러다임으로 부각중인 BIM 기술은 기획 설계 시공 단계를 거쳐 유지관리 단계에서의 활용성을 넓히고 있으며 시설안전공단에서는 총 5만 6,450개 이르는 국내 사회간접자본(SOC)인 시설물 유지관리에 BIM 기술을 도입하기위한 연구를 진행중에 있다. 현재 국내에서는 웹 기반 시설물관리 시스템(FMS : Facility Management System)을 통해 국내 시설물의 기본정보와 점검 및 관리 정보를 서비스 중에 있으나 대상 시설물의 설계도면 및 유지관리 도면, 안전점검 실사 보고서 등이 2D 기반으로 유통되고 있어 BIM 적용을 위한 많은 체계마련이 시급한 실정이다. 이에 본 논문에서는 2D 기반의 시설물 유지관리 체계에 BIM을 활용하기위한 방안을 제안하고자 하였다.

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.
