When Building Information Modeling (BIM) was introduced at the early stage, it was only utilized as a three-dimensional visualization tool. Nowadays, however, BIM is being studied for increasing design productivity and managing enormous information on building life cycle. One of the representative research is developing 'common prototype BIM libraries'. BIM data made of common prototype libraries should be utilized in various ways, quantity takeoff, code checking, energy analysis and so on. However, common prototype BIM libraries are not enough to estimate accurate cost. For example, composite wall libraries should be divided into several single objects, wall structure and finishes, for the quantity takeoff and construction cost calculation. In this paper, we are suggesting an automated division algorithm of composite wall and developing a system prototype for it. This study is expected to reduce extra modeling work and contribute to fast and accurate cost calculation in the construction.

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.

Roof structure of the traditional buildings in the Northeast Asia region including Korea contains the most complicated and crucial components of the building and therefore the issues such as cost down, productivity and the attempt to combine the traditional building methodology with contemporary building technology turn out to be vital to the survival of the old yet disconnected traditional building industry. One of the distinctive modern building technologies is handling life-cycle building information by constructing virtual buildings using BIM, building information modeling tools. In this paper we follow a procedure to implement some of the design modules to be applied in BIM tools which are platforms for constructing virtual building models. We focus on Gong-po components namely the bracket-sets which are the essential part that connects the middle parts to the top parts (the roof structure) which are considered to be the most elaborate parts of the traditional buildings. The target building to work with in this paper is the Sung-Rye-Moon which has special cultural and social meanings nowadays and we tested our understanding and the design modules such as the bracket-sets by constructing a virtual building model of Sung-Rye-Moon.

The construction projects are recently having changes in their magnitude and complexity. Therefore, the amount of information created and managed by participants over project phases is enormous and this may cause difficulties in consistent and integrated data management. Because of the change in construction projects, there is a need to apply more logical and systematic ways to deal integrated data management. For the solution to this, BIM(Building Information Modeling), a new paradigm for integrated management of the information over project life-cycle, has been seriously considered. Also, the Korean Public Procurement Service announced that project over 50 billion Korean Won should introduce BIM into procurement starting from 2012. However, the studies and development have lack on studies of applying BIM and managing the data made using BIM in pre-design and maintenance stage. In pre-design stage, the concept of schematic design model is made to support for making major decisions concerning the size, shape and cost of the project. To decide the cost for the building in this stage by making use of BIM, estimating the amount of building materials used for constructing should be preceded. In this study, the pre-design BIM is explained to gain a better understanding of its process, since this paper focused on space programming stage. Finally, the paper suggests the concept process of estimating the amount of materials in building interior finishing from selecting the type for the elements of each space made to support the client for making decisions in space programming stage based on pre-design BIM.

BIM은 건설 전단계를 포괄하는 새로운 패러다임으로서 2016년 조달청이 발주하는 정부기관 건축공사에서 BIM 설계를 전면 의무화 하는 등 BIM 기술의 도입이 점차 가속화 되고 있다. BIM 기술은 건축분야에서 벗어나 점차 사회기반시설물로 적용 범위가 확대되고 있으며 이미 국내 토목건설 공사 파일럿 프로젝트를 통해 적용 타당성이 검증되고 있다. 이러한 추세는 건설 생애주기에서 가장 넓은 범위를 차지하는 유지관리 단계로까지 확장되고 있으며 선진국에서는 경제성 검토와 BIM기반 유지관리 가이드라인도 출간되고 있는 실정이다. 이에 본 연구에서는 사회기반 시설물의 BIM기반 유지관리 기술 도입의 경제적 타당성 분석을 수행하였다. 교량과 터널을 적용 가능한 사회기반 시설물의 범위로 판단하였고 편익/비용비(B/C ratio)를 활용하여 BIM 기술의 유지관리 도입의 경제적 타당성을 분석 하였다. BIM 모델의 세밀도별로 시나리오를 가정하여 분석한 결과 편익/비용비는 교량의 경우 중간 이상의 세밀도에서, 터널은 높은 세밀도에서 1.00 이상의 값이 산출되어 시스템 도입의 경제성이 있음을 확인할 수 있었다.
