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.

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.

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 was carried out to establish the database system by using the safety inspection and in-depth inspection results for infrastructures such as bridges, tunnels, dams, and water supplies. A classification system of each facility was proposed by standardizing items for inspection & diagnosis in order to automatize work process. Also, it justifies data structure based on database from pre-investigation to field survey, evaluation of facilities, and report making. In addition to this, it suggests improvement plans of relative regulations and guidelines such as Facility Management System(FMS), operational regulation, and inspection detailed guideline to make inspection result database of infrastructures which can be used effectively.

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.

The frequency and severity of damage caused by extreme climate events are increasing due to climate change. If the infrastructure is not prepared for the risks of climate change, property loss may occur in the facility itself and its surrounding areas. Therefore, climate change adaptation technology should be introduced to reduce future losses. Policy makers need to understand the economic impacts of each technology in order to select an appropriate option. Both the primary damage, which is the direct damage to the facility, and the secondary damage, which is the damage to the surrounding area due to climate change, should all be identified for understanding the economic impact from adaptation. This paper presents a procedure for deriving primary and secondary damage reductions from introducing adaptation technologies and suggests a methodology for evaluating adaptation technology specific to each infrastructure.

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.

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.
