The application of the BIM for the KEPCO' new headquarters in Naju involved alternative approaches and accompanied many trials-and-errors as the project adopted new targets and purposes that were not used in Korea before. In particular, for a large BIM-based project, clearly defining the BIM-including the objective, scope and the outcome-is critical for a project owner. For a successful implementation, project owners should improve the utilization of the BIM. Against this background, this research examines the case of the BIM application for the KEPCO' new headquarters in Naju, identifies its effects and problems, and proposes how to improve application of the BIM for public projects. The improvement in the BIM application can be divided into several stages: project order, design development, construction, and post-construction maintenance. In the initial stage, it is important to fully discuss the project planning among participants, and clarify the goal, scope, expected outcomes and role of the BIM. In the design stage, the level of detail (LOD) for the 3D model should be defined in consideration of information use in the stages of estimation and construction. In the construction stage, the scope of project that is managed based on the processing and use of the BIM data should be clearly given and understood. After construction is complete, measures should be sought to use the BIM for maintenance, and corresponding requirements and outcomes should be provided. The analysis is expected to provide basic data for successful implementation of BIM-based public projects, by assisting project owners and involved parties in enhancing work in different stages of a project.

Building Information Modeling (BIM) is a digital facility representation of the physical and functional characteristics, and is the process of creating, using, and maintaining shared knowledge resources as a tool for making decisions throughout the facility s life cycle. The expected benefits from the early introduction of BIM were ideal, but large construction companies, which initially invested a lot of money, are also cutting costs and are looking for alternatives with Small-BIM. In order to introduce BIM without failure, medium-sized construction companies(MSCC) lacking expertise, financial strength, and organizational capacity compared to large corporations, this study examines the introduction cases of MSCC and suggests obstacles and solutions to those problems. 1. Current market situation of BIM - The stage of re-examination of the BIM field, 2. Application of BIM to MSCC - Minimizing the risk. 3. Barriers to introducing BIM - Initial investment cost, additional work, professional manpower, lack of information, etc. 4. Solutions to the obstacles to introducing BIM - Selection of programs and systems, how to establish relations with the field management, how to secure BIM personnel, etc. 5. BIM Utilization of MSCC - Daehan Steel, Digital Design Lab, etc. 6. IS-Dongseo BIM - Pilot Project, Tool Selection, TFT Operation, Future Plans, etc. 빌딩정보모델링(BIM)은 시설물의 물리적, 기능적 특성을 디지털로 표현한 것이며, 시설의 생애주기 전반에 건친 의사 결정을 위한 도구로써 공유 지식 리소스를 생성, 사용 및 유지하는 프로세스이다. 초기의 BIM의 도입으로 인한 예상된 이익은 매우 이상적이었으나 초기에 많은 비용을 투자했던 대형건설업체들도 비용을 축소하고 있으며 스몰빔으로 대안을 찾고 있다. 대기업에 비해 전문가, 자금력, 조직 여력이 부족한 중소건설업체가 실패 없이 BIM을 도입하기 위해서 본연구에서는 중견업체 도입 사례들 검토하고 도출되었던 장애요인과 해소방안을 제시하고자 한다.

BIM technology, which is widely used in the construction industry, has been introduced in various fields for the purpose of saving construction cost and reducing construction schedule. However, in the case of BIM-based cost estimate, there are various trials and errors in applying BIM technology which can be applied for calculating quantity and cost estimate. BIM-based cost estimate can improve the quantity accuracy and allow to easy modifications that were not expected in 2D-based construction process. However, for this purpose, it is necessary to take into consideration that interoperability between BIM data and cost information should be planed in advance. Besides, the definition of a BIM data specification is also required for the seamless data exchange and integrity in each phase of the construction process. Therefore, in this study, we propose a BIM - based cost estimation method and technology in each type of work applicable to the current domestic construction industry.

The consistency between a building information model(BIM) and drawings are very important and has a critical impact on the usage of BIM throughout the project life-cycle. The purpose of this study is to develop a checklist for the consistency check between BIM and drawings. In this research, requirements for drawings in the construction documentation phase were analyzed. In generating drawings based on BIM, a checklist can help practitioners confirm what to modify in the BIM model and what to modify in CAD drawings. Finally, it is expected that the work efficiency will be improved by reducing the unnecessary work by distinguishing the elements that can be extracted from the BIM model from the elements that requires additional works when generating BIM-based drawings.

The current study focused on the utilization of building information modeling (BIM) data in steel-frame structures, which help to reduce project durations because they employ prefabricated structural members that are assembled on-site. In addition, a business process model was proposed using BIM data collected during the preconstruction, structural steel fabrication, and on-site construction phases of an actual steel-frame project. The ultimate expectation is that BIM data support at each phase, as well as the increased understanding among project participants, will result in an increase in project management productivity. The results from the current study are summarized as follows: To implement a BIM capable of application to steel-frame projects and data utilization, existing theories were studied to develop the construction project steps, both generally into the preconstruction (A1), steel fabrication (A2), and on-site construction phases, (A3) and specifically into 19 BIM-applicable phases. Based on the derived BIM-applicable phases, the model elements of the BIM object were identified, and the shortcomings of existing steel-frame projects were ameliorated, resulting in an improved data flow model. Moreover, for the proposed BIM data flow to progress efficiently, the BIM specialist needs to be well-acquainted with the phase-specific three-dimensional (3D) model output, and the infrastructure to construct an error-free 3D model must be provided. Based on the actual construction example, the BIM data utilized steel-frame projects - via production reports, clash checks, two-dimensional (2D) drawings, four-dimensional (4D) simulations, and 3D scanning - to make cooperation and communication among participants easier.
