Build-Transfer-Lease (BTL) was introduced to the domestic construction market in 2005. Now, seven years later, the BTL model is most active for educational facilities. In 2011, 93 educational facility projects entered the maintenance stage. Considering the characteristics of today's BTL projects for educational facilities, the main issues are the initial performance and maintenance of educational facilities and the service-providing status for the 20-year operational management period, in relation to providing safety and convenience to students, the facility users. Seeking a solution, local education offices and departments in charge of BTL under the Ministry of Education, Science, and Technology have been exploring various methods of evaluating operational maintenance performance from various perspectives. For educational facility BTL projects, however, the appropriateness of initial operation performance evaluation, rather than considering the 20-year operational management period, is controversial in regards to sustainability. On this account, performance evaluation items in four areas-operational maintenance evaluation, facility performance status evaluation, maintenance subject evaluation, and sustainable change response evaluation-should be extracted. An indicator of facility performance evaluation is presented in this study through an AHP survey targeting experts, as part of establishing an operation performance evaluation system for educational facility BTL projects.

This study focuses(selected) on garden facilities of designer gardens created at the 1st and 2nd Seoul Garden Shows and examined installed facilities at each designer garden by categorization according to type, material and functions. The study observed problems occurring from maintenance of garden facilities as time passes by and collected basic data to develop maintenance guideline aiming to make contribution to further spreading and promotion of high quality garden culture. This study examined all gardens created at 1st and 2nd Seoul Garden shows in 2015 and 2016. There were 18 gardens built in 2015 and 16 in 2015.The study looked at responsible entities for maintenance of facilities and examined maintenance system for managing these gardens. Garden facilities of the study were categorized into paving, facility for rest, playground, water facility, environmental sculpture and planting media facility according to categorization by landscape design standards and construction guidelines. Target gardens of this study are maintained mostly by citizen gardeners who are passionately carrying out maintenance work while communicating with designers. However, these citizen gardeners lack technical knowledge to manage various facilities. Also, maintenance manuals submitted by garden designers do not offer sufficient details on facility maintenance which calls for professional maintenance and clear instructions on facilities from early phase of design.

Many construction projects have used the building information modeling (BIM) extensively considering data interoperability throughout the projects' lifecycles. However, the current approach, which is to collect the data required to support facility maintenance system (FMS) has a significant shortcoming in that there are various individual pieces of information to represent the performance of the facility and the condition of each of the elements of the facility. Since a heterogeneous external database could be used to manage a construction project, all of the conditions related to the building cannot be included in an integrated BIM-based building model for data exchange. In this paper, we proposed an ontology-based facility maintenance information model to integrate multiple, related pieces of information on the construction project using industry foundation classesbased (IFC-based) BIM data. The proposed process will enable the engineers who are responsible for facility management to use a BIM-based model directly in the FMS-based work process without having to do additional data input. The proposed process can help ensure that the management of FMS information is more accurate and reliable.

The purpose of this study is to provide a basis for calculation of school operation fees for normal functioning of the school facilities, and facility maintenance and repair cost through their life spans, considering remodeling of the facilities and changes of their functions. This study analyzes maintenance and repair records during the three years from 2003 to 2005 in primary, middle and high schools in Incheon Metropolitan city and also the facility management and operation expenditure of the same schools in the city during the year of 2005, and presents quantified unit cost of each item according to the area, the age of the facilities, and the number of classroom, student, and lessons given. The calculation can be a basis for both BTL school facility managers and the general school facility mangers to budget school facility maintenance cost appropriately and the quantity of energy, water, electricity, and telephone fees calculated here can be a criteria for the managers to check the normal maintenance of their facility.

시설 관리는 시설의 자산적 가치뿐만 아니라 시설 환경 및 사용자 성능까지도 시설 관리 수준에 의해 결정된다는 점에서 매우 중요하다. 시설 전체 생애 비용 중 운영 및 관리 비용은 시설의 용도와 사용 정도에 따라서 초기 건설비용의 3배에서 10배에 달한다. 효율적인 시설 관리는 다양한 용도로 건설된 다수의 시설을 관리하는 공공 시설관리 기관의 경우 더욱 중요하며, 특히 제한된 자원(인력/장비 등)과 제한된 예산으로 다양한 사용자를 위한 다양한 시설을 관리할 때 이 중요성은 증폭된다. 본 연구는 전국에 있는 16개의 공공 시설관리기관의 시설관리 현황을 조사 분석하였다. 주요 조사 항목은 1) 시설 관리 시스템 구성 및 활용현황, 2) 중장기 수선 계획 수립 및 활용현황, 3) 수선대안 선정 시스템 수립 및 활용현황 등이다. 본 연구는 분석 자료를 기반으로 지방 공공 시설관리 기관에서 사용하고 있는 시설관리 시스템의 개선 사항을 도출하고 추후 연구 방향을 제시한다.

It is focused on a methodology to establish a optimal inspection cycle of electrical facility of railroad Decision method of optimal inspection cycle is a process which establishes maintenance plan for facilities' immanent function as using reliability theory in operation term In order to ensure normal operation in a given condition, the decision method is logical for selecting effective maintenance plan to consider characteristic of system In estimation of failure rate, critical facility is selected firstly. After that, proper distribution function on each facility is decided to investigate distribution function for extraction of failure rate. Next, cost produced by the case that facility's failure is occurred is surveyed. Finally, maintenance method developed until now is investigated, before suitable model for the facility applying maintenance method is developed, and that maintenance decision is made. Therefore, this process is the method to find optimal inspection cycle for reasonable cost and effective reliability on facility.

This study purpose is seeing that the independent standard sufficiently reflecting the characteristics of the school facility as the basic material needed to calculate the maintenance and repair expenses is needed to make a more realistic and valid qualitative VFM analysis of the school BTL project. this study attempted to develop the standard for the repair cycle and rate and economic year of the school facility. The quantitative VFM analysis should be conducted based on the repair cycle and repair rate proper to the school facility, not the residential space, when calculating the maintenance and repair expenses of the operating expenses of the school facility. An attempt was made to calculate the repair cycle, repair rate and economic life of 114 component materials of the school facility judged to be able to explain the school field best. And it was confirmed that the repair and maintenance expenses more is needed to be set by about 35% than the existing maintenance and repair expenses.

The objective of this study is to develop an improved algorithm for layout problems. Computerized facility layout program was also applied to solve the layout problem in locomotive maintenance workshop. The current facility layout is structured in the large space without considerations of many variable factors. For this reason, effectiveness of layout results in loss on effective space utility. This study is to develop an algorithm in the consideration of importance weight and desirable shape of specific department in the computerized layout planning and quantitative relationship rating between each department was used. Standard process duration of locomotive maintenance workshop was used to select the main activities of locomotive maintenance work. This study could generate more efficient facility layout design to reduce the number of movement frequency and travel distance in maintenance workshop.
