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.

The purpose of this paper is to provide baseline on the current status and the activation of BIM in civil engineering which can integrate and manage the information and tasks generated during the life cycle. Hierarchical analysis was conducted to identify the level of BIM application, recognition survey for practitioners, and activation plans. The survey results show similar trends in BIM activation inhibition factor, the need for BIM, the effect of BIM and the future possibility of BIM. The utilization of BIM and the technical training in the civil engineering field were lower than those in the architectural field. The analysis of AHP(Analytic Hierarchy Process) is performed to identify the degree of importance in financial, operational, investment, technical, and institutional sections as its activating factors. As a result, the technical factor points the highest degree. Thus, study shows the direction to apply BIM in civil engineering in the future by suggesting an efficient plan.

In architecture projects, BIM library has widely been using for prefabrication of products and design process. However, since the shape of structures is different by each project in civil engineering projects and a shape representation system is complicated, it is not easy to develop a standardized BIM library. To solve these issues, this study develops BIM library based on standardized 2D shop drawings for civil structures. The standardized shop drawings, which are the targets of the BIM library model, should be first selected. Besides, in order to define modeling scope with the level of general and shop drawings for each structure, LOD(Level of Detail) and breakdown structure are determined, and development methods of families of 3D object type including 2D profile and rebar through commercial software are established. With these, properties of BIM library are configured, and a utilization model of the BIM libraries is constructed for 3D modeling and a simulation using the BIM library. Therefore, this study can identify properties that are necessary when IFC schema is configured for civil engineering projects. For future, it is expected that easiness of BIM design for the civil engineering projects and generation, management, and analysis system of BIM library for road projects will be secured.

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.

As the utilization of the BIM model increases in the design and construction stages of a construction project, the utilization of BIM in the maintenance stage can also increase. In the maintenance stage, BIM objects created in the design and construction stages that have already been completed are used. Therefore, it is necessary to verify the reliability of whether the used BIM object is a certified model created in the design stage. In particular, the reliability of the BIM model becomes more important in a project such as railway facilities composed of various construction activities with civil engineering, architecture, electricity, signal, and track work. This study proposes a methodology of using blockchain technology as a way to secure the reliability of the BIM model used in the maintenance phase, and constructs the block structure and detailed process for applying the blockchain technology to BIM. In addition, by applying this process to the BIM model of an actual facility to generate a block, it was confirmed that the blockchain technology can be used as a tool to secure the reliability of the BIM model.

Owing to the increase in large and complex construction projects, the design paradigm of architecture and civil engineering projects has changed from 2D CAD to 3D CAD. For this reason, to meet the strong requirements of project contractors, various efforts have been made to adopt a Building Information Modeling (BIM) technology for effective construction management. On the other hand, compared to architectural projects, only a few civil engineering project cases have been conducted in the perspective of public contractors. This is because the characteristics of civil project contractors and the negative pursuit of adopting BIM technology due to the lack of a current BIM system and technologies. Recently, positive changes in adopting BIM technology for public projects were anticipated by public owners, such as the Public Procurement Service and the Ministry of Land, Infrastructure and Transport. In this regard, this study analyzed the current BIM technology status of public owners in Korea to adopt the BIM policies and guidelines of the Korean government. Strategies for adopting BIM technologies for Korean public owners are also discussed based on an analysis of civil engineering BIM project cases.

Recently, the adoption of BIM technology in domestic civil engineering projects has continually increased both in its numbers and scope. However, the BIM model was developed and used after the 2D design was developed instead of creating the BIM model from the conceptual design phase. BIM must be used throughout every phase of design and construction to use BIM for its original purpose. However, if BIM application is applied in heavy civil projects without a step-by-step guideline, it can confuse the market and face industry resistance to using BIM. Therefore, BIM is currently being used step by step in the civil engineering field by using BIM as a conversion design. However, the BIM conversion design method, currently being performed in the Preliminary design stage, has many difficulties due to low work efficiency. This paper analyzes the existing process of converting a 2D design into a 3D BIM model while addressing the issues related to its low work efficiency. To this end, a novel approach to 2D to BIM conversion for the design development stage is proposed.

In BIM environments for infrastructures, civil structures such as road, bridge and tunnel etc., created into 3D objects, integrated with their properties, securing BIM design productivity is very critical during 3D modeling. To solve this issue, configuring BIM libraries so that the users can utilize prefabricating in advance 3D objects that have been applying repeatedly during BIM design is essential so much. Current BIM libraries have made focused on Ready-Made for architectural facilities. However, establishing environment for delivering BIM library for civil facilities is very sparse. Accordingly, this study developed a web-based sharing system for delivering BIM library contents based on standardized drawing for civil area. To do this, we have analyzed core features and operation system of BIM library sharing system in domestic and overseas. Besides, functional requirements that are necessary for developing BIM library sharing system was derived, and through operation scenario configuration, the web-based system was developed according to the detailed mechanism. It is expected that this system can enhance BIM design productivity during library based modeling, and can be utilized as construction supporting tools that can help construction managers to make a design change.
