  • 고속도로 건설사업은 기본설계, 실시설계 단계에서 합리적이고 경제적인 대안 선정을 위해 대안간의 총생애주기비용(LCC)을 산정, 비교하게 된다. LCC 산정시에는 각 대안의 보수주기, 보수율, 보수비용 등의 유지관리 정보가 필요하며, 한국도로공사의 경우에는 자체 개발하여 운영하고 있는 Hi-유지관리시스템의 정보를 이용할 수 있다. 그러나 LCC를 고려하지 않은 기존 유지관리시스템의 데이터베이스 구조 및 입력체계로 인해 유지관리 정보를 효율적으로 획득 및 적용하기가 어려워 전문가의 설문에 기초한 유지관리 정보를 주로 활용하여 LCC를 산정하여 왔다. 본 연구에서는 실제 유지관리 자료를 실용적으로 사용할 수 있도록 연간일상유지관리 개념을 제안하였다. 제안된 개념에 따라 한국도로공사의 Hi-유지관리시스템 자료를 분석하여 일부 제시하였으며 실제 고속도로 건설사업에 적용하여 본 결과, 엄밀한 LCC 분석을 위한 유지관리 데이터가 부족한 현 상황에서 효과적으로 적용할 수 있음을 확인하였다.

  • 고속도로 건설은 여러 국가에서 거의 완료되었으며, 정부나 고속도로 관계기관은 유지관리쪽에 초점을 맞추고 있다. 교량을 효과적으로 유지관리하기 위해, 시스템 신뢰성을 이용한 교량의 잔존수명을 예측하는 것은 매우 시급하다. 그리고 시스템 신뢰성을 이용한 교량의 유지관리 모델을 개발하는 것은 필수적이다. 이 논문에서는 시스템 신뢰성과 라이프 타임 분포를 이용하여 예방 유지관리(Preventive Maintenance)와 사후 유지관리(Essential Maintenance) 모델을 개발하였다.

  • The practiced conventional methods for maintenance management in Malaysian Polytechnic faced many issues due to poor service delivery, inadequate finance, poor maintenance plan and maintenance backlogs. The purpose of this study is to improve the conventional method practices which tend to be ineffective in Malaysian Polytechnic. The case studies were conducted with eight Polytechnics and are selected based on conventional method practices and its major problems. There are around 32 Polytechnics in Malaysia and almost are using conventional methods. The number is considered very big indicating that the use of modern Information and Communication Technology (ICT) is still very limited compared to other institutions of higher learning in Malaysia. The overall findings of this research indicated; poor service delivery, inadequate financial, poor maintenance planning and maintenance backlogs. There is also need to overcome less man power competencies of maintenance management practices which existed with all eight Polytechnics. The proposed system is intended to be used for maintenance management practices at Malaysian Polytechnics in order to provide high-quality of building facility with safe and healthy environments.

  • At this point of time that it is required to improve educational environment and the function of educational facilities as well as interests on educational facility business is increasing, it is actual situation that unsystematic maintenance of educational facility is not being able to cope with the change caused by introducing the 7th curriculum. Also, in spite of enormous career in maintenance work, the function is not properly performed because of unsystematic management. In case of educational facility manager, he parallels performing general administrative work and facilities maintenance work not as a maintenance expert but as a member of administration office. So there are difficulties in performing maintenance work, and systematic maintenance work cannot be expected because of lacking maintenance manual. Therefore, in this research, I would like to investigate and analyze the status of educational facilities and to elicit the point of issue as a basic research to save maintenance expenses and to make pleasant educational environment.

  • As the importance of building maintenance is being emphasized, studies regarding the efficient building maintenance focus on the evaluation of the maintenance plan, implementation and its cost only while the evaluation of the maintenance performance is nearly ignored. At this point when the importance is placed on the performance design we need to have methods to improve maintenance performance of the buildings in Design Phase. The purpose of this study was to set the design evaluation items to improve the maintenance performance of the buildings. Through the review of the existing literature, we set the concept of the maintenance performance and suggested evaluation items to evaluate the maintenance performance through the analysis of domestic and overseas certification and design guidelines.

  • To many developing countries like China, the practical way to constant development of city construction is low consuming. The basic methods of low-cunsuming landscape construction: 1) Low building consumption: Decreasing construction quantity. Using low-costing material. Designing low-consuming landscape. Reusing of building material. 2) Low energy consumption: Decreasing water consumption. Consuming and enrichment of earth fertilizer. Decreasing electrical consumption. 3) Low maintenance: Adapting natural material. Using local plants. Special design to decrease maintaining. Because of many reasons, China has not yet adapting Low-consuming Landscape Construction.

  • This paper focused on problems of design, construction, and maintenance caused by construction implementation processes. They were analyzed through case study of structure safety diagnosis projects. From the case study, it is expected that the introduction of Construction Management from the first stage of procurement will improve construction cost increase or burden on small design company. It strengthens coherent management from design and source contractor selection to build review of responsibility. The coherency will prevent changes in designing or infirm unreliable construction. It is desirable that expert opinions are considered when structure changes and establishment occur and that, if necessary, actions such as source selection, periodic audits, and diagnosis arc checked and fed back to maintenance.

  • BIM has been a reliable construction project management tool to handle various kinds of construction information generated in the facility life cycle. To take these advantages, researchers have been promoted numerous studies in a residential, a commercial, and an educational facilities with a large number of on-going projects. However, despite running as the role of essential energy supplier, power plant related BIM research is relatively insufficient than others. In particular, due to the extending of the facility service period and the requirement of the complicated construction project management for 'overhaul' and 'repowering' in the power plant maintenance phase, the needs for using BIM have been increased gradually. For using BIM based maintenance, it is needed to consider an information collecting methods and necessary to develop an appropriate breakdown structure to share information. Therefore, 'EBS' is produced by reviewing the previous research related to BIM and analyzing the repair activities in the maintenance phase. Proposed 'EBS' must be useful not only a judgment between capital expenditure versus revenue expenditure but also appropriate maintenance strategies development for property management.

  • The poor maintenance and management of HVAC systems finally lead to the shortening of the life expectancy and result in the increase of operating costs and energy consumptions due to low efficiencies. Also, it is essential to try to develop ways to adequately maintain and to use the building facilities efficiently in order to preserve earth environment and the limited resource. In this study, an analysis on the maintenance and management cost for HVAC systems was carried out with the capacity of equipment. Besides, the LCC(Life Cycle Cost) based analysis was carried out to verify the effect of the doing maintenance and management. As the results, the case of the good maintenance and management is able to save LCC to 11 % than the case of the poor method.
