최근 건설사업시장의 개방과 건설사업관리제도(이하CM)의 도입으로 국내 건설업계 및 생산시스템에도 많은 변화가 일어나고 있다. 이에 따라, 건축물의 초기시설비는 물론 유지관리 및 최종 폐기단계까지의 비용을 종합적으로 고려한 건물생애주기비용(이하 LCC)에 대한 중요성이 증대되었으며 특히 기계장치의 유지관리비 중 많은 부분을 차지하는 공기조화시설 부문에서 LCC가 주로 검토되고 있다. 그러나 국내에서는 공기조화 설비의 LCC에 대한 절차 및 기준 등이 미비하여 효과적인 LCC분석이 이루어지지 않고 있다. 본 연구는 최근 수행된 국내 공기조화 설비분야의 LCC분석 사례를 조사하여, 국내 공조설비의 LCC분석의 문제점을 분석하였다. 또한 사례 분석을 중심으로 공조설비의 LCC분석 절차를 제시하고 이 절차에 따라 7개의 사례를 비교분석하였다. 그 결과, LCC측면에서 최적 대안을 선정하는 경우 각 대안 별로 뚜렷한 차이를 보이고 있는 에너지비용과 초기투자비를 주된 비용요소로 고려하는 것이 가장 효과적인 것으로 나타났다.

The importance of LCC analysis has been enlarged. Also, it would be necessary to computerize LCC analysis for accurate and logical analysis of LCC. In other papers, they showed LCC analysis model but the study of database development which could be applied in LCC analysis have been undeveloped. As a result, the final goal of this study is to develope LCC database. And this progress is devided 4 steps as design, construction, maintenance and disposal and derived the detailed cost item in the progresses. Futhermore, it would be possible to develope cost DB, fluent DB, general DB, building section DB, material DB and to propose database which would be applied in accurate and logical analysis of LCC.

Reports on VE/LCC based coastal structural design were analyzed to derive possible improvement. VE/LCC technique may be effectively applied to making decisions in coastal structural design. However, it has not been well utilized in recent projects for some problems. Therefore, recent project reports on VE/LCC have been analyzed and merits and demerits were classified. Then, the reason why VE/LCC cannot be effectively applied to real projects was drived. Finally, some pre-requisites to improve the technique were summarized.

For a successful construction project, systematic and objective decision-making is a prerequisite from the planning and designing stages. However, previous LCC analysis methods have focused only on simple cost savings and the accompanying economic efficacy while missing the environmental aspects of a structure. Although recently, a new approach of integrated $CO_2$ analysis has been introduced, which is more advanced than the existing simple LCC methods, it is difficult to collect all of the data necessary for each evaluation item since the product-specific cost is not presented under the LCC. In this research, cost evaluation items were selected by relatively high weights and items with heavy influence over a decision-making process in order to suggest an LCC-LCA integrated analysis model that is useful in comprehensively assessing the economic cost and environmental cost throughout the whole life cycle of a structure. The developed LCC-LCA integrated analysis model was applied to actual practices and compared with previous methods to test the model's effectiveness.

This study is a LCC case analysis on the school one of the BTL projects which is constructed by private organizations and rented to government. According to the RFP to make out documents, it is performed the case analysis based on the results of LCC calculation about maintenance & conservation costs; repairing costs and replacement costs. It is analyzed LCC on maintenance & conservation costs for 20 years(rent period) and 65 years(life cycle). As a result of LCC analysis, about more than 50% of total LCC are architectural works and the rest of them are machinery works, electric works, and civil works in the order. And it is also suggested some problems and their solutions to perform LCC analysis on the current BTL projects of school.

Recently, the demand on the practical application of life-cycle cost effectiveness for design and rehabilitation of structure is rapidly growing unprecedently in engineering practice. Accordingly, in the 21st century, it is almost obvious that life-cycle cost together with value engineering will become a new paradigm for all engineering decision problems in practice. However, in spite of impressive progress in the researches on the LCC, the most researches have only focused on the Deterministic or Probabilistic LCC analysis approach (Level-1 LCC Model) at design stage. Thus, the goal of this study is to develop a practical and realistic methodology for the Lifetime risk based Life-Cycle Cost (LCC)-effective optimum decision-making at design stage.

Building information modeling (BIM) is a smart construction technique that is recognized as essential for current construction facility projects. The Public Procurement Service (a construction project-ordering agency) announced a plan to introduce BIM and has required changing the operation of projects by using BIM design information. LCC analysis is essential for items, quantity, and cost information of the construction, and it is expected that efficient work will be achieved by using BIM design information. In this study, a BIM-LCC analysis system was established for selecting optimal design alternatives by actively using open KBIMS libraries. The BIM-LCC analysis system consists of a single alternative and an optimal alternative LCC analysis, but it has a limitation in that only the architecture and machine libraries have been applied. However, by applying BIM, practical use and work efficiency can be expected. In order to use the method as an LCC analysis support tool with BIM design information in the future, it will be necessary to collect user opinions and improve the UI.

In this study, the concepts of integrated VE analysis assessment is introduced in order to achieve "Design for Deterioration performance" in design VE phase. For this purpose, a framework for fuzzy reliability based LCC and value analysis model using fuzzy logic based approach for breakwaters Projects is suggested. It is anticipated that the methodology Proposed in this paper can also be utilized in the design and maintenance phase of other facilities where decision making is made for the fuzzy reliability based life cycle cost and value analysis.

To analyze the total cost of ownership in a building construction project, we have to consider initial plan, maintenance and operation cost, in addition to the design and construction cost. This is called "Life Cycle Cost (LCC)." Currently, it is difficult to analyze LCC because of a lack of data and the appropriate criteria. This study tries to suggest a way to analyze the LCC of building construction projects, and apply it to case studies of modern apartment houses and Han-Ok, a type of traditional Korean house. The case studies found that a Han-Ok is more efficient than a modern apartment house from an LCC point of view, in terms of maintenance and operation cost.

The purpose of this research is to identify problems and solutions of domestic Life Cycle Cost analysis in BTL(Build-Transfer-Lease), a PFI(Private Finance Initiatives) project. It is expected BTL would be quite effective delivery method for public construction introducing the private's major capital investments and technologies, and obviously LCC analysis is becoming more important factor for success of BTL projects. Nevertheless, there are still some complicated issues in LCC analysis, a technique for selecting the optimal VE(Value Engineering) proposals and estimating OM&R (Operation, Maintenance, & Repair) cost of the buildings, and has been applied limitedly. This research mainly focuses on educational facility, as most frequently delivered by BTL currently, especially with two levels (Alternative LCC and Building LCC) , which is occupied main potion in BTL project. In addition, it identifies four main problems and suggests their solutions through case studies focusing six major factors (WBS, Repair Information, Life Cycle, Time value of money, Repair Information Database, LCC Model) from three projects. Advanced development of this research requires closer partnership between the private / public sectors, and their long term strategies.
