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.

With the promotion of the u-City project in recent years, the need for the systematic and efficient management of ground and underground facilities comprising the urban infrastructure has been increased. Considering that the diverse services provided in the u-City are closely related to the physical environment of the city itself, including its location and condition, the core of such management must be to continuously maintain these facilities in a normal state, based on accurate data collection from the facilities. This paper discusses a method of collecting the sensor and the object data that are needed to accurately understand the state of the underground facilities, and presents a plan to build an Underground Facility Management System on this basis. This plan is then verified using a scenario test performed by a prototype system.

본 연구에서는 자연재해에 따른 재해 발생 시 신속하고 효율적인 대응을 위하여 시설물의 중요도 위험도 피해액 평가 인벤토리를 구축하였다. 인벤토리 구축을 수행하기 위해서 재해에 따른 시설물의 위험 발생 시 피해 시설물에 대한 구분 및 분류가 이루어져야한다. 하지만 재난관리가 수행되어야 하는 시설물 건축물의 정보가 정부 여러 기관에서 각기 다른 형태의 정보로 관리되어짐으로써 재난관리 업무의 효율적 운영에 대한 문제가 제기되어 왔다. 따라서 본 연구에서는 미국의 HAZUS-MH와 DIMSuS의 위험도와 중요도 개념을 기반으로 피해 시설물의 중요도, 위험도 등을 평가할 수 있는 항목들을 선정하고 국내 시설물 분류, 건축법규 및 자산 가치 산정 정보를 활용하여 시설물 재해 대응을 위한 인벤토리 구축을 수행하였다. 본 연구에서는 대구 성서산업단지를 TB지역으로 선정하고, TB지역내의 수변구조물, 산업시설, 주거시설 등 다양한 시설물의 속성 정보를 수집 구축하였다. 또한 신속한 재해 대응을 위해서는 시설물 정보와 공간정보를 융합한 복합적인 정보가 필요하기 때문에 TB지역의 공간정보를 구축하고 시설물의 위치 정보를 생성하고 속성 정보와 연계하여 통합 인벤토리를 구축하였다. 향후 본 연구에서 제안한 인벤토리 시스템을 활용하여 신속한 재해 대응을 위한 의사결정 도구로 활용될 것으로 판단된다.

The existing facility management system is capable of managing two-dimensional and three-dimensional models that were driven from maps and registered documents. However, it is not capable to collect various fields data on a real time and operate the integrated systems. To supplement those obstacles, constructing a facility management system based on ubiquitous environment is needed. Therefore, this research has proposed the modified UFID(Unique Feature IDentifier), which is more suitable for the facility management by modifying management agency and serial codes system in the existing UFID. In addition, we established the procedures for ubiquitous environment based on facility management using proposed UFID. The feasibility of this research was assessed through case study focused on roadside trees. It is considered that the results can be applied to many other ubiquitous environments based on facility management.

Recently, the paradigm shift of new construction into efficient operation and maintenance of infrastructure is seen. Also, concerns about infrastructure safety, especially the aged infrastructure, are on the increase. This study evaluates the current status of infrastructure safety and maintenance using data from 1994 to 2014 in Facility Management System operated by Korea Infrastructure Safety Corporation. Also, a quantitative analysis of safety performance of infrastructure is conducted to find out the enhancement of infrastructure safety in Korea. It was found that safety of facilities in Korea have been enhanced for the past decades. Improvement of safety performance of facilities is attributed to periodic safety inspection and repair and reinforcement. The result of the study can be used as a basic material for efficient and effective facility maintenance policies and strategies.

우리나라에서는 1960년대부터 현재까지 도시화가 급속도로 진행되고 있다. 도시화가 진행됨에 따라 대부분 농경지로 사용되었던 토지의 이용 방법이 변화하였고 포장면적이 증가하면서 불투수면적과 강우유출량 또한 증가하였다. 이러한 현상으로 인해 도심지의 유출량이 증가하여 도심홍수가 빈번해지고, 비점오염물 증가로 인한 수질악화 등의 환경 문제가 더욱 심화되고 있다. 따라서 도시화로 인한 피해를 저감시키고 물순환 체계를 효율적으로 관리하기 위한 저영향개발(LID, Low Impact Development) 기법의 필요성이 대두되고 있으며, 그로 인해 LID 기법의 가치가 재조명되고 있다. 현재 LID 기법과 관련된 많은 연구가 진행되고 있지만 LID 시설물에 대한 이해와 유지 관리 필요성에 관한 연구가 미흡한 실정이다. 따라서 본 연구에서는 LID 기법을 보다 쉽고 효율적으로 적용하기 위해 국내 9종의 매뉴얼과 국외 2종의 매뉴얼을 검토하여 국내 실정에 적합한 LID 시설 유지관리 기법을 고안하여 LID 개념을 통합적으로 정립하였으며 LID와 관련된 시설물, 모니터링 요소, 유지관리 등의 기술적인 정보를 제공하기 위한 한국형 LID 시설유지관리 매뉴얼을 작성하였다. 매뉴얼은 첫째, LID 전반적인 이해를 돕기 위해 LID 정의, LID 시설물의 종류, 설치기준 및 운영 관리기준에 대한 내용을 다루고 둘째, LID 시설물의 특징, 구성, 설치가능 지역, 설치 시 고려사항, 유지관리 기법, 설치 예에 대한 내용으로 구성하였으며 이외에도 시설물의 일반적인 점검사항, 토지이용별 고려사항 등 시설물 설치 후 점검 방법, 유의사항 등을 제시하였다. 향후 매뉴얼의 타당성을 검토하기 위해 부산대학교 양산캠퍼스에 완공된 LID 실증단지의 시범 LID 시설물에 적용하여 국내 LID 시설물에 대한 매뉴얼의 적용성을 높일 예정이다.

To reduce facility management costs and safety concerns due to aging of facilities, it is important to estimate the future facilities' condition based on facility management data and utilize predictive information for management decision making. To this end, this study proposed a methodology to estimate facility elements' condition using XGBoost. To validate the proposed methodology, this study constructed sample data for road bridges and developed a model to estimate condition grades of major elements expected in the next inspection. As a result, the developed model showed satisfactory performance in estimating the condition grades of deck, girder, and abutment/pier (average F1 score 0.869). In addition, a testbed was established that provides data management function and element condition estimation function to demonstrate the practical applicability of the proposed methodology. It was confirmed that the facility management data and predictive information in this study could help managers in making facility management decisions.

In this study, legislative and policy issues related to advancing the maintenance system of water resource facilities were presented by investigating and analyzing the degree of aging and management status of water resource facilities. Data from the comprehensive Facility Management System (FMS) operated by the Korea Infrastructure Safety Corporation were collected and used to analyze the aging of water resource facilities. Using safety grade data categorized by facility, type, local area, and grade, the ratio of dangerous facilities and the aging rate were calculated to analyze the status of water resource facilities and guidelines and manuals related to water resource facilities were investigated. Through this, four required actions to address legislative and policy issues were presented: 1) Readjusting the scope of water resource facilities and supplementing guidelines and manuals, 2) Establishing a maintenance system considering changes in disaster conditions, 3) Improving the FMS and activating standard linkage services, and 4) Establishing a facility asset management system.

Recently, the scale and technical complexity of agricultural production has been growing. Therefore, agricultural facilities are being gradually diversified, expanded, and made more complex. To furnish Korea's agricultural industry with international competitiveness, it is thus necessary to introduce new management techniques. The PCM (procurement-construction-maintenance) information management system for agricultural facilities is established by setting up its WBS (work breakdown structure). In this study, the WBS of a facility such as facility, space, element, works, and resources is analyzed. Following this analysts, a WBS of an agricultural facility that is appropriate for the PCM information system of an agricultural facility, is proposed by deriving it from actual WBS.
