Recently, interest in the necessity and practical application of BIM (Building Information Modeling) is also increasing in the civil engineering field. However, there are difficulties in building BIM models and utilizing BIM modeling in the civil engineering field due to various reasons. To this end, it is necessary to develop management tools and research on management methods that can effectively utilize the BIM library in the civil engineering field. Libraries in the civil engineering field are complementary to each other, so library management in consideration of library management in various combinations and continuous updates is important. BIM library management was proposed through the development of a management tool that reflects these characteristics, which is expected to contribute to improving productivity in the field of civil design.

본 논문에서는 토목분야에 BIM 기술을 적용하기 위해 파라메트릭 모델링 디자인 기법을 기초로 한 토목 구조물 모듈 라이브러리를 구축하고자 하였다. 국제 표준설계방법론에 부합하는 개방형 BIM을 구현하기 위해 표준정보모델은 IFC로 연동하며, 형상 분류체계는 PLIB Part 42(ISO 13584-42)로 정보 분류체계는 Omniclass와 통합건설정보 분류체계를 따른다. 토목분야에서의 BIM 기술은 토목 구조물 표준 라이브러리를 통해 동시공학적 협업설계를 이룰 수 있을 것으로 판단된다.

BIM(Building Information Modeling) technologies should be applied for the construction life cycle to maximize its efficiency, but the utilization for the construction phase has been significantly lower than that for the planning and design phase. Recently, some of BIM techniques such as 3D design review, 4D schedule management and so on are being introduced for efficient managing to the big national construction projects. In this study, the utilization plans of BIM are presented for the construction phase of civil engineering facilities. The methods of utilization of BIM are discussed for each type of construction, and the techniques applied to the Seoul Subway Lot No. 919 are analyzed for checking the applicability and usability. In particular, a web construction management system based on BIM can help field engineers, headquarters and contractors to use BIM more effectively, and it can be extended to maintenance phase for more efficiencies.

Recently, BIM proliferates at high speeds so that BIM planning is trying to be used in various kinds of engineering. However, when using different software during design phase and construction phase, the problem of mutual compatibility is coming out. Even the BIM technology has been used or the practical applicability has been made into result, it would be fair to say that BIM has limitations in the visual level. In this research, it is meaningless to obtain the BIM result as the primary purpose. As the usefulness of it is judged incomplete, we committed to master the trend and problems of terrain spatial information systems and BIM. Furthermore, the plan of building the BIM in the civil field, especially the civil-BIM based on the technology ofterrain spatial information has been presented. It can be judged through this research that the high-capacity DB of BIM occurred during the whole process may cause poor performance of the following stage the structure system which connects the terrain spatial information and civil-BIM. In order to manage the optimal full cycle, the spatial analysis technology of the stages after choosing the DB has been described.

Building information modeling (BIM) has been receiving attention as an integrated information model instead of CAD since the 2000s. BIM technology was first used in the architectural field and was later introduced to the civil engineering field. However, the government announced a plan for the application of BIM to 20% of all SOC projects from 2020, so the adoption of BIM technology is expected to accelerate. In order to successfully adopt BIM, a systematic structure should be supported for integrated design information and implementation technology. Also, it is important to establish the relationship between information systems because many complicated factors are intertwined in the construction industry. In this study, we propose a framework for constructing integrated information through identifying the information relations for introducing BIM in the civil engineering industry. We applied this framework to a bridge project to confirm its effectiveness. This study can be applied to the integrated management of the construction process and costs by introduction of a work breakdown structure (WBS) to BIM. In addition, this study is expected to contribute to the adoption of BIM in the civil engineering field through the proposal of information system standardization in this field.

Industry Foundation Classes(IFC) is the core product schema for ensuring the interoperability of information in Building Information Modeling(BIM) environment. However, since current IFC is mainly focused on building structure. there are limitations in the generation of functional information of components when applied to civil infrastructures. Previous studies have proposed IFC-based new entities for the civil infrastructures, it takes long time to support them in BIM authoring software packages. In this study, we proposed practical rules to apply IFC-based information modeling using BIM authoring software and additional new entities for the civil infrastructure through attributes and information mapping. The availabilities of proposed method were examined using the rail and sleeper information models based on an extended IFC data schema for the railway infrastructures.

BIM technology, based on 3D model of civil engineering structures, creates and manages information of the structures throughout four stages: Planning, design, construction, and maintenance. BIM is now used around the globe for improvement of the construction productivity. However, in order to expect the efficient engineering work, collaboration system between participants in a construction project is necessary. Therefore, in this paper BIM based CPLM (Construction project lifecycle management) system was designed and developed by analyzing the requirements of participants of a construction project. CPLM system offers an environment which enables the sharing and management of information according to the each stage of construction. CPLM is expected to aid cooperative decision-making during the overall construction process through the process innovation and the efficient data management.

In this paper, we propose a novel method for converting the existing 2D processes in the design and construction phase of civil engineering, to the future BIM-based processes. First, we compare and analyze the actual application processes of the outputs of the existing 2D method and the outputs of the 3D BIM method, for the whole process of BIM design of earthworks and road structures and integrated utilization of quantity, process(4D) and construction cost(5D), in view of life-cycle. The proposed method acquire the outputs of the design phase integrating IFC international common standard file information and CBS/OBS/WBS standard classification scheme information, and acquire the outputs of the construction stage by using an integrated utilization module for quantity, process(4D) and construction cost(5D). Ultimately, we intend to commercialize the step by step technologies for BIM design and construction in civil engineering by using the proposed method.

BIM (Building Information Modeling) is a new paradigm that includes construction life-cycle, and BIM has become mandatory regulation according to the Public Procurement Service since 2016, which accelerates its application. BIM is now expand from architectural field to infrastructure industry. Through pilot projects, BIM has been challenged with verification process. This trend has affected to maintenance and operation (M&O) phase of construction life-cycle. Advanced country has already published their research and result with feasibility study and guidelines. In this paper, we conduct the feasibility study to adopt BIM-based infrastructure management system. Bridges and tunnels were selected as application target, and benefit/cost ratio were used. The result shows that BIM-based infrastructure management system is feasible when the level of detail is more than "Medium" in bridge, and "High" in tunnel.
