정부에서는 안전사고의 방지, 기존시설의 수명연장과 성능개선을 통한 재정투자의 효율성을 제고를 위하여 ｢지속가능한 기반시설 관리 기본법(이하 “기반시설관리법”, 공포 ’18.12.)｣을 시행(’20.1.)할 예정이다. 이 법에서는 개별법에 따라 상이하게 관리되는 기반시설의 유지관리 수준을 상향 평준화하기 위하여 최소유지관리 공통기준을 제정하도록 하고 있으며, 기반시설 관리체계의 분석과 정부시책에 대한 검토 등을 통하여 유지관리 개선 방향을 결정하고, 이를 근거로 최소유지관리 공통기준을 마련중이다. 공통기준의 지침화를 위해 기반시설 유형별 적용성을 평가하여 범용성과 확장성을 검토할 예정이다.

현재 국내의 기반시설 안전·유지관리는 소관 개별법령에 의거하여 이루어지고 있으며, 규모나 중요도 측면을 고려하여 정해진 시설물은 「시설물의 안전 및 유지관리에 관한 특별법(이하 “시설물안전법”)」에 의해 관리되고 있다. 이와 같이 분절적으로 이행되고 있는 기반시설 관리를 총괄하여 관리수준을 상향시키고 정부의 재정지원 원칙을 명문화하여 효율적 유지관리를 유도 하고자 하는「지속가능한 기반시설 관리 기본법(이하 “기반시설관리법”)」이 시행 예정(‘20.1)이다. 본 논문에서는 법 시행에 앞서 기반시설 유형별 점검·진단등의 체계와 방법을 비교·검토함으로써 국내 기반시설 유지관리 현황을 파악해보고자 한다.

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.

This paper proposes a process to predict the maintenance cost for the aging urban infrastructure and to manage the facilities reasonably by establishing the budget execution plan based on prediction. It is anticipated that preemptive maintenance will be possible through this, and it will be expected that the average performance grade of the facility will be improved and the management cost will be reduced through longevity improvement.

국가 전략적 차원에서 전체 사회기반시설물에 대해 미래에 필요한 유지보수 예산 파악하는 것은 매우 중요한 부분이다. 그러나 현 재 국내에서는 전체 대규모 시설물에 적용할 수 있는 유지보수비용 예측 기법이 거의 전무한 실정이다. 본 연구에서는 현재 국내에서 가용한 자 료와 적용 가능한 예측모델을 토대로 우리나라 전체 향후 SOC 시설물에 대한 향후 유지보수 투자 규모를 예측하였다. 실제 지출비용과 비교하 여 가장 적합한 예측모델을 선정하고 관리주체에서 과거에 지출한 유지보수비용 자료를 이용하여 일부 모델은 개발하여 교량, 터널, 포장, 항 만, 댐, 공항, 상수도, 하천, 항만 등의 사회기반시설물에 대한 최적의 미래 유지보수 비용을 산출하였다. 앞으로 10년간 총 비용예측결과, 8종의 사회기반시설물에 대하여 약 23조원이 필요한 것으로 나타났으며, 가장 비용이 크게 발생하는 시설물은 도로포장, 도로교량으로 나타났다.

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.

The Ministry of Unification has published the North's social and economic indicators about 'North Main statistical indicators' every years. However, "North Main Statistical Indicators" does not reflect the status and the level of North Korean infrastructure. The purpose of this study is to survey maintenance status and level of North Korean infrastructure, and to propose a regional assessment results.

Main infrastructures in Korea are maintained according to the result from periodical in-depth inspection. The process is based on the ‘Special Act on the Safety Control of Public Structures’ and accompanied specific guide. The Act has mainly focused on the physical condition and safety of structures up to now. Recently we are faced with the threats coming from aging of structures and climate change. These interior/exterior changes are strong challenges to maintain expected performance of structures. What is more, convenience for people and functionality are came to the fore as important indices. In these circumstances, the government of the Republic of Korea is preparing for a paradigm shift to performance-based maintenance system which can evaluate integral condition of structures with regard to the various performances. In this study, performance indices, detailed inspection items and following inspection techniques are defined. The grade assigning method using the results from inspection and integral evaluation procedure are suggested. This can be used for establishing a improved and long-term maintenance strategy toward an appropriate goal considering various performance characteristics.

Infrastructure of the Korean construction industry has been rapidly aging in spite of the major qualitative growth over a short period of time for the last fifty years and interest in the social needs for maintenance has been increasing. Consequently, the paradigm of the domestic infrastructure maintenance market is changing and the needs of users are gradually increasing. According to the results of the domestic maintenance survey and analysis, first-class and second-class public structures specified by the 'Special Act on the Safety Control of Public Structures' are showing remarkable results and effects through the enactment and improvement of related laws. In this study, a survey was conducted for the domestic maintenance market and its status and ensuing reactions regarding policy were proposed for future improvement.

Recently, various studies for reducing GHG and energy consumption are increasing in the world. In this study, the previous studies were analyzed to improve reduction methods and propose alternatives in terms of global competitiveness and environmental protection. The result shows systematic research and policy support are necessary to reduce GHG and energy consumption in maintenance field of infrastructure

Infrastructure safety and maintenance management(ISMM) is one of the most important parts for improving level of people's welfare. The government needs to set up their own improvement strategy for ISMM system. This study was initiated to suggest the strategy to improve ISMM system with long term perspective. In order to investigate the current status and problems of ISMM system, this study reviewed various literature related to the issues of the foreign ISMM systems and conducted the interview with ISMM experts. The strategy would be expected greatly to improve the safety and maintenance management system for domestic infrastructure.
