A preliminary study was conducted to introduce the concept of asset management in developing maintenance strategies for public facilities. A survey was carried out to analyze public institutions' maintenance status, thereby leading to an asset management system. The survey identified the maintenance priorities for the asset management system, evaluated the weight factor in selecting facilities, and analyzed the current maintenance system. The purpose of the study is to assess the system transitioning to asset management systems considering the life cycle of the facilities from safety management-oriented maintenance policies. As a consequence of the survey results, the study presents data for establishing an asset management system.

Recently, the maintenance concept of infrastructure has been changed from the stability management of the structure determined by the safety inspection of the existing facilities to the asset management related to evaluating and managing the performance of the facilities. For management of the property of the facilities, it is necessary to efficiently classify their information for the maintenance and service level of the facilities and to manage them. In the case of power plant facility, especially, it is a complex structure, which is constructed in a various component and detail. In this study, therefore, the components of power plant facility were classified into facilities, spaces, parts, and elements considering the type of integrated construction classification system in Korea. To reflect the deterioration rate of the facility in accordance with environmental conditions such as airborne salt and humidity etc., it was classified by adding direction, interior, and exterior condition of each component not to be considered in the existing classification system for its effective and systematic maintenance, since it is generally located in the coastal area due to the operation of the power generation structure. The classification system developed in this study can be used as fundamental data for development of the computer system for asset management of power plant facility.

Rail transit agencies in Korea have been struggling to set up a performance-based rail facility maintenance plan because there are no formal definition and decision criteria for aging infrastructure. This study investigates the definition of aging infrastructure through extensive literature review and identifies benchmarking criteria through comparison with rail transit facility management systems in Korea and United States. As results, an aging infrastructure should be defined considering both service age and performance level of a facility. The priority of repair/replacement should be also determined with reasonable criteria based on relationship between service age and performance level. To determine the definition and decision criteria, a practicable classification system for aging rail transit needs to be established in accordance with classification system for performance assessment. Furthermore, a comprehensive database needs to be built including useful life, performance level, and maintenance cost of each component of rail transit. It will allow establishing an efficient budget execution plan for aging infrastructure.

본 연구 성과는 국내토목구조물의 유지관리 업무를 지원하는 분야에 해당한다. 현재 우리나라 토목시설물은 법정비를 통해, 유지관리업무를 체계화시켜나가고 있는 상태이지만, 아직 그 결과물에 대한 DB 시스템이 일반화 되어 있지 못하며, 일부 개발된 툴들도 서로간의 유기적인 연결은 부족하다. 본 연구를 통해 개발한 지하구조물 유지관리 DB시스템을 이용해서 시설물 관리주체, 진단업체, 유지관리업체들이 상호간에 유기적으로 연결되고 효율적으로 데이터들을 관리할 수 있는 시스템을 제안하여, 국내 기간산업의 유지관리 업무 효율성을 높이는데 이바지 하고자 한다.

자연재해에 따른 피해로부터 국민의 재산과 인명 등을 보호하기 위해서는 예상되는 재해로부터 발생하는 피해규모에 대한 분석과 예측을 통한 대책 마련이 필요하다. 본 연구에서는 최근 10년간 발생되어진 자연재해 원인과 시설물별 분류 결과를 통하여 가장 많은 피해가 발생되어진 호우 태풍에 따른 공공시설물 피해에 대한 피해규모를 예측할 수 있는 손상 손실함수를 개발하고자 하였다. 공공시설물 중에서도 제외지에서 대부분의 피해가 발생하는 하천시설물 외에 국민의 생활영역인 제내지에서 피해규모가 크게 발생하였으며, 국가재난관리시스템(NDMS)의 피해내역 시설물 분류가 명확한 도로 시설물과 상 하수도 시설물을 함수 개발 대상물로 선정하였다. 도로와 상 하수도 시설물에 대한 국가재난관리시스템(NDMS)의 과거 피해내역과 호우 태풍에 의한 피해발생 규모로서 일반적으로 활용되고 있는 침수예상도 범람도 등을 활용하기 위하여 피해액을 종속변수로 침수면적을 독립변수로 이용하여 도로와 상 하수도 시설물의 피해액을 추정할 수 있는 손실함수를 개발하였다. 개발되어진 도로 시설물 및 상 하수도 시설물에 대한 손실함수는 향후 재해에 따라 발생 가능한 추정 피해액 규모 분석 등을 통하여 재해저감 대책을 위한 기초자료로 활용될 것으로 기대한다.

This paper provides core standardization items and method for the building information modeling (BIM) based maintenance and management (M&M) of civil infrastructure. Value chain of the M&M and characteristics of BIM technology has been analyzed and compared. As a result, it has been revealed that the initial activity recording damage information is very similar to the BIM-based information operation. The core standardization items for generation and operation of BIM data were identified according to the M&M value chain, The identified items were categorized into common standard item and specialized items for M&M of civil infrastructure, and proper government funded organizations for each standardization items were introduced on the basis of the roles in the laws.

Despite the significant benefits of BIM (Building Information Modeling), it is not being vitalized for the facilities that are designed based on the horizontal and vertical alignments because of the lack of flexibility in manipulating surface models generated based on alignments. Alignment-based design produces a surface model in one piece through the definition of the typical cross-section along the alignment. Therefore, linking these alignment-based 3D surface models, that are not modularized and difficult to partition, to the required attribute information is very difficult This paper presents design of a flexible BIM technology suitable for the alignment-based civil infrastructure by providing the partitioning functionality for surface models, the contents library for cross-sectional design components, and the attribute information along with the critical functionalities needed for the design, construction and maintenance of alignment-based civil infrastructure.
