The purpose of this paper is to understand the key factors for efficient maintenance of rapidly aging facilities. Therefore, the safety inspection/diagnosis reports accumulated in the unstructured data were collected and preprocessed. Then, the analysis was performed using a text mining analysis method. The derived vulnerabilities of tunnel facilities can be used as elements of inspections that take into account the characteristics of individual facilities during regular inspections and daily inspections in the short term. In addition, if detailed specification information and other inspection results(safety, durability, and ease of use) are used for analysis, it provides a stepping stone for supporting preemptive maintenance decision-making in the long term.

3D-based BIM(Building Information Modeling) technologies can be utilized effectively as a means of systematic management of facility information for safety assurance and effective maintenance of waterworks facilities. In this study, BIM models of water treatment facilities that can be used as basic data for BIM-based maintenance of waterworks facilities were developed. Information exchange and generality of the developed BIM models were evaluated by conducting interoperability analysis of IFC(Industry Foundation Classes) conversion models. In addition, the application of COBie(Construction Operations Building information exchange) was recommended as an effective countermeasure to deal with technical limitation regarding exchange and utilization of facilities-related information through current IFC models. The results of this study can contribute to the development of BIM-based maintenance system for waterworks facilities.

PURPOSES : This study is to improve the highway management and rehabilitation efficiently by method for asset management. METHODS : Based on the literature review, The concept of this paper is to investigate the use of asset values from a Bridge management system to improvement of maintenance system more efficiently. This study is suggested for an evaluation method based on the current bridge condition by Written-down replacement cost of the assets. RESULTS : We suggests the optimization methodology of road asset valuation for budge distribution and performance measure. CONCLUSIONS : We evaluate all of national highway's bridge by the optimization methodology of road asset valuation, and suggest application methods of asset result.

최근 공공시설물의 노후화에 따른 사회문제가 빈번하게 발생하고 있으며, 이에 따라 시설물에 대한 국민의 불안감도 증가 하고 있다. 향후 10년 내에 급증하게 되는 시설물 노후화 문제의 효과적인 대응을 위해 현재의 사후적인 유지관리에서 예측을 통한 선제적 유지관리로의 패러다임 전환이 시급한 실정이다. 본 연구에서는 빅데이터 시범분석을 통해서 교량, 터널, 공공건축물 일부에 대해 FMS 축적된 유지관리 데이터를 활용하여 지역별·환경별·공용년수별 취약요소를 도출하였고, Social Media의 비정형 데이터 분석을 통해 국민이 체감하는 불안/불편요소를 도출하였다. 또한 교량 취약요소의 손상발생패턴 분석을 통해 향후 선제적으로 관리해야 하는 유지관리 항목 및 추가적으로 확보해야 하는 디지털 정보 등을 제안하였다.

This paper proposed the measures that to predict changes in the state of the individual tunnels, and maintenance costs during its life cycle by using the big data of tunnel facilities. This is expected to be used to efficiently establish long term maintenance plans for tunnels based on data-based engineering analysis.

Many of the facility management information system are being operated by each government departments and Acts. Therefore, it is difficult to share and integrate data through the network because data standard codes are not established. In spite of these problems, the Special Act on the Safety Management and maintenance imposes duties on the main agent of national infra structure management and the maintenance results should be integrated in Infra Structure Information Management System(FMS). Thus we propose the structure classification standard codes for the FMS to integrate and analyze safety and management data.

This research is a basic study to develop mid - and long - term data base platform for maintenance of aging infrastructure (bridges, tunnels, retaining walls, road facilities, etc. In this study, the degradation and damage data and experiment data obtained from various monitoring technologies are secured in the medium to long term, and the degradation environment and damage model are developed based on the data acquired later. Predicted and standardized services to the management or the people of the nation. In this study, the database will be constructed at the planning, design and implementation stage, and mid - and long - term data will be used for precision safety diagnosis report and monitoring measurement report.

Recently, the importance of facility maintenance has been increasing due to the problems caused by the occurrence of new types of disasters and the deterioration of facilities. However, it is difficult to maintain consistent facilities because the related laws are dispersed depending on the size and purpose of facilities. In addition, when a collapse occurs, there is difficulty in response activity. This paper analyzes the problems in the maintenance of facilities in accordance with the deterioration of facilities and draws out the Mediumand long-term development plans of facility maintenance field

The purpose of this study was to suggest the foundation of LDA-based model for infrastructure maintenance cost evaluation. The LDA-based model enables to evaluate not only overall maintenance cost, but also various combination of each cell of risk matrix.

Ministry of Oceans and Fisheries has developed the port facility management system(POMS) that can be run systematically manage safety inspection and maintenance results about the mooring facilities, counter facilities and pier pavement in a national 60 port. This paper contains a description of the POMS.

본 연구에서는 비용예측모델과 성능예측모델을 이용하여 네트워크 레벨에서 향후 교량과 터널 유지관리 비용과 성능을 예측할 수 있는 방법론은 개발하였다. 현재 국내의 시설물 유지관리 관련 연구는 대부분 단일 시설물에 집중되어 있어 도로망차원의 네트워크 레벨 분석 에는 적용하기 어렵다. 따라서 시설물군 단위로 유지관리 계획을 수립해야하는 실무주체에게 유의한 정보를 제공하지 못하고 있는 실정이다. 본 연구의 예측모델은 시설물의 성능에 현재 시특법에 의해 평가하고 있는 상태외 사용성과 기능성을 포함하였으며, 기본 분석과 확장 분석을 통해 각 시설물의 조치 시기와 연간 예산을 추정할 수 있다. 또한 사례 분석을 통해 기술적 타당성을 검증하였다. 본 연구의 방법론이 활성화된 다면 다수의 시설물의 비용대비 미래 성능을 파악할 수 있으며, 효과적인 중장기 예산 수립을 할 수 있을 것으로 판단된다.
