In recent years, building information modeling (BIM) has been an important issue within the architect, engineering, and construction (AEC) industry. BIM provides a way to share and exchange semantically rich information about the buildings in order to achieve a successful level of collaboration, communication, and interaction between stakeholders throughout the life cycle of the project. However, despite the recognition of its potential, BIM has not yet been utilized in the construction, operation, and maintenance stages because of the need to reorganize the BIM by reflecting the as-built status of the buildings. In order to improve and increase the use of BIM at all phases of a project, several research efforts are exploring the creation of an as-built BIM that is based on advanced sensors. However, there is a lack of literature and investigation on this research area to date within the domestic AEC industry. The aim of this study is to suggest ways in which BIM can be utilized within the construction, operation, and maintenance stages based on advanced sensors so that it is an approach that might be usefully carried forward. This paper begins by presenting a review of the existing BIM research and achievement in order to determine the limitations of the use of BIM in the domestic AEC industry. Conclusively, this paper suggests a direction for the future applications of BIM and describes how it can benefit from additional research.

상수도시설은 준공후 관련지자체에 이관 관리하는 시설로서 사용관종이 현재 다양하게 생산 보급되고 있어 관종 선정시 다각적인 측면에서 검토하여 채택하여야 한다. 최근 한국토지공사에서 사용하고 있는 상수도 관종은 대부분 택지개발계획 등 인허가 당시부터 관리주체인 지방자치단체 등과의 협의과정을 거쳐 선정되는 경우가 많아 자재선택에 한계성이 있다. 이를 극복하기 위해서는 자재 성능에 대한 공사내 명확한 기준이 제시되어야 한다. 상수관종을 선정하기 위한 가장 중요한 요소는 경제성으로 판단되는데, 관종의 경제성은 시공비와 자재비를 포함한 단순 공사비에만 국한되는 것이 아니라 유지관리비용을 포함한 생애주기비용(LCC: Life Cycle Cost)을 평가하여야 한다. 따라서 본 연구에서는 한국토지공사에서 택지지구 조성을 위해 사용한 배수관.급수관용 상수관종에 대한 경제성 평가기준을 제시하였고, 평가기준에 따라 각각의 택지지구 조성사례별로 종합적인 경제성 평가를 수행하였다. 보다 풍부한 자료를 바탕으로 객관적인 경제성평가 기준을 수립하기 위한 전(前)과정으로 이해되길 바라며, 설계시부터 객관적인 평가기준을 통해 합리적인 상수관을 선정하여 지금까지의 상수관종 자재선택의 한계를 최소한으로 축소하고자 하는데 가장 큰 목표를 가지고 있다.

This study aims to improve bibliographic data of public libraries by linking service data, which are produced out of library service programs. Service data collected from the seven award-winning public libraries were selected and analyzed. A Bibliographic Framework is used for linking bibliographic data and service data. Interfaces are also suggested for the two-way data linking. The results can be used to obtain 1) selective and value-added bibliographic data, 2) bibliographic data updated continuously throughout the lifecycle, 3) structured service data for preservation and sharing, and 4) bibliographic data linked to the additional external linked data.

In general, it is known that the concrete ballast track is possible to reduce a cost of maintenance activities cause of maintenance free by restrictive maintenance in application of track ballast structures. However, if deteriorations and fracture mechanism of a material are considered, proper maintenance activities and repairing are continually required. For the problems, we evaluated an economical efficiency of the gravel ballast and the concrete ballast on a proper level of maintenance activities. As the method based on history path is difficult to obtain sufficient reliabilities cause of an absence of real data for maintenance activities, we chose the delphi survey method by professional group, and we obtained the appropriate index and profiles for maintenance activities. As a result, we founded that effects for cost reduction can be expected by preventive maintenance management, and we proposed economical restrictions and life cycle cost for track ballast structures in a life cycle.

Recently, maintenance of public rental housing becomes a critical issue because its expenditure possesses the majority proportion of life cycle cost. The countries, such as USA and Singapore, have introduced the approaches for advanced property management, which are cost-effective in the maintenance management. However, as maintenance management system becomes advanced, risks associated with its application are also increased. Therefore, it is needed to assess the appropriate applicability of public rental housing maintenance management considering the constrains in domestic construction industry. The main objective of this study are to investigate international cases and systems and to propose strategic introduction, which satisfies the regulations and policies for domestic public rental housing. In order to evaluate the suitability of the investigated systems, practitioners' opinions were reviewed through the questionnaire surveys using analytic hierarchy process (AHP). The surveys indicate that advanced asset management was the suitable process for managing efficiently domestic public rental housing. Moreover, the results showed each weights of considerable criteria for assessing the effective application of maintenance management, and would contribute to further detailed and systematic management.

Because of a wide range of performance and diversity of project and uncertainty caused by complexity and a number of stakeholder, conflict occur necessarily in Urban generation including large-scale and many project which do the same time, for long time. so active conflict management which recognized risk before the fact and deal with conflict is necessarily needed. Therefore, This study is typing conflict cases and indicating critical conflict type through analysis on conflict case about process and stakeholder of urban generation to offer information which is referred to finding a solution when conflict occur by forecasting conflict that can occur before the fact.

재난발생 위험은 불확실성을 내포하고 있으며, 이러한 불확실성 요인을 줄이고 사전에 소멸시키는 일은 매우 중요한 사항이 될 수 있다. 또한 재난관리 관점에서 그것이 발생했을 때 어떤 식으로 대응할지에 대한 과정이 체계적으로 갖추어져 있어야 하며, 복구 및 재발 방지를 위한 지속적인 노력이 수반될 필요성이 있다. 본 연구에서는 기후정보를 활용한 중장기 수문예측을 실시하고 통합홍수위험평가 시스템 구축을 통한 홍수위험도 분석을 실시하였다. 이를 위하여 우리나라 243개 지자체를 대상으로 홍수관련 위해성, 노출성, 취약성 자료를 수집하여 표준화하였으며, 전문가 Delphi-AHP 설문조사 분석을 통하여 가중치를 적용하고 위험도를 예측 평가하였다. 이러한 중장기 위험 예측 정보는 한 달 또는 수개월 전에 지자체 행정력을 집중 및 분산시키고, 수재해(홍수/가뭄 등) 위험관리 계획 수립이 가능하여 재난관리자에게 유용한 정보로 활용될 수 있을 것이다. 또한 재난의 생애주기(Life Cycle)별 예방, 대비, 대응, 복구 단계에 따라 사전과 사후에 가능한 주요 활동들을 구체화 할 수 있으며, 시간 스케일별 기후예측 정보를 활용한 재난관리 패러다임 전환과 골든타임 확보 등 수자원예측 분야 기술적 진보를 이룰 수 있을 것으로 기대한다. 향후 통계 역학 모형 기반 중 장기 예측 정보의 신뢰도가 향상 된다면 보다 다양한 분야 예측 정보 서비스 및 활용이 가능할 것이다.

Recent years, the construction projects of a world-wide have changed toward integrated evaluation considering all environmental and economic aspect for ecological construction.. The object of this study is to suggest the method and system for integrated analysis VE/LCC and LCA. In order to integrate and analyze environmental and economic aspects of alternative design elements, decision maker should handle simultaneously much information such as cost, document and drawing. This study presents applicative methods of WBS for integrated management of these information. Also, this study presents a decision support system that can manage DB easily by using VE, LCC and LCA analysis module separately.

300억원 이상의 국가 및 공공기관 발주공사에 대해 최저가낙찰제를 대신하여 종합심사낙찰제 전면 실시 등의 내용을 담은 국가계약법 시행령이 개정되어 2016년 1월 1일부터 시행에 들어갔다. 종합심사낙찰제는 가격 뿐만 아니라 공사수행능력, 사회적책임을 종합 평가하여 낙찰자를 선정하는 제도로 기존의 최저가낙찰제에서 발생한 덤핑낙찰 및 이로 인한 잦은 계약변경, 부실시공, 저가하도급, 임금체불, 산업재해 증가 등의 문제점을 해소하기 위해 도입된 제도이다. 종합심사낙찰제 도입에 따라 공사 품질이 제고됨으로써 생애주기(lifecycle, 유지보수비용 등을 포함) 측면에서의 재정효율성 제고를 비롯하여 불공정 하도급 관행 개선 등 건설산업의 생태계 개선과 함께 시공결과에 책임짐으로써 기술경쟁 촉진 등 건설산업의 경쟁력 강화 효과도 기대된다. 또한 국가계약예규도 개정되어 주계약자관리방식에 의한 공동계약(주계약자 공동도급)이 최저가낙찰제에서 종합심사낙찰제로 전환됐다.
