  • 건축분야에서 BIM이 널리 사용되면서, 토목구조물에 BIM을 적용하려는 노력이 최근 급속히 증가하고 있다. 그러나 기존 상용 BIM 소프트웨어의 기능은 건물 등의 건축물 중심으로 특화되어 있기 때문에 선형 중심의 토목구조물에 적용하기에 많은 어려움이 따른다. 본 연구에서는 철도 궤도부의 객체 정보를 관리하기 위하여 선형을 다룰 수 있는 소프트웨어와 BIM 소프트웨어간의 정보공유를 통해 캔트가 반영된 정보모델 생성방법을 제시하였다. 철도 궤도부 모델링은 궤도부 구조물을 연속 구조물과 비연속 구조물로 분류한 후, 연속 구조물을 선형 소프트웨어에서 생성하고, 이후 공유된 선형정보를 이용하여 비연속 구조물의 정보모델을 생성하는 절차로 이루어진다. 이 때 비연속 구조물은 BIM 소프트웨어에 전달한 이산화된 궤도 선형 및 캔트 정보를 바탕으로 비연속 구조물 각각의 위치, 회전 정보를 계산하는 알고리즘을 통하여 생성된다. 본 연구에서 제시한 방법을 오송 철도종합시험선로에 적용하여 그 실용성을 검증하였으며, 생성된 정보모델을 기반으로 명확한 객체 식별과 속성정보 추출 및 객체별 물량산출이 가능함을 확인하였다.

  • BIM 설계에서 라이브러리의 구축 및 활용은 매우 중요하다. 기존 컨텐츠의 재활용이 가능하므로, 설계를 보다 효과적이고 효율적으로 진행할 수 있다. 건축분야와 달리 토목분야, 특히 철도시설분야에서는 라이브러리의 구축 및 표준화가 미진하다. 따라서 본 연구에서는 철도시설분야에 3차원 객체 라이브러리를 구축하고 표준화하고자 한다. 철도시설물 분류체계 및 관련도면을 수집 및 분석한다. 분석된 표준도면의 항목과 분류체계 항목을 매칭하였다. 각 항목별로 라이브러리가 필요한지 여부와 그럴 경우 어떤 소프트웨어가 적절한지를 검토하였다. 사용가능한 소프트웨어는 주로 Civil 3D와 Revit 등으로 나타났다. 향후 이를 바탕으로 철도인프라 3차원 라이브러리의 속성 항목 및 명세서를 설계하고 라이브러리를 구축할 예정이다.

  • In order to use BIM as a tool for improving the productivity and quality of products in the construction industry, a BIM model must be created from the design stage first. Infrastructure structures such as bridges and tunnels are mainly created based on three-dimensional alignment in the generation of BIM models. Especially, generation of BIM models based on three-dimensional linearity has high task difficulty and algorithms for automating BIM modeling for railway infra structures have been suggested in previous studies. This study improved the BIM modeling automation algorithm of railway infrastructures and developed a system based on the algorithm so that it can be easily used by ordinary users. The system was built as an add-in system of Autodesk's Revit. As an improvement first, it is possible to arrange different libraries for each pattern, enabling various uses. In addition, it can be created models of several members with a single process and the system can automatically places structures that are added periodically, such as Rock Bolt and Fore Polling. Finally, 3D length information and volume for each pattern are automatically calculated for more accurate 3D-based volume calculation. This study contributes to increasing user accessibility by building a BIM modeling automation algorithm into a system. The system is expected to improve the efficiency of BIM modeling creation of linear-based infra structures, including railway infrastructure.

  • The interest in the Building Information Modeling (BIM) technology has risen remarkably due to the effects on construction work period reduction, cost reduction, work safety improvement, and other factors. In civil engineering field, BIM applications mainly focus on data modeling and virtual construction. In this study, we present the BIM-based virtual construction and analyze the effects of BIM for the railway facilities so that the conventional approach to the equipment operation plan can be improved in order to prevent safety accidents which can result from unclear information during the operation plan. The BIM-based virtual construction technology is applied to establish the construction plan for the site with constraints, the installation of steel girder needs to be completed, avoiding interference with the existing high-speed railway operation within a given limited time. A virtual construction model consisting of topography, structures, equipments, and avatar was built and more detailed model, including safety guard rails, was then created. Specifications of the construction equipment were input as a database, and the virtual construction model was manipulated in the equipment operation planning. Through the BIM-based virtual construction, including the verification of alternative construction method, 311 million won was saved and the construction period was shortened by 87 days compared to the original plan. In addition, it was shown that the interest and participation of the construction workers can be increased by providing the 3D virtual scene for real construction work and various safety hazards occurring during equipment operation can be effectively removed in advance by the interactive worker education.

  • 기존의 철도교량 유지관리체계는 주로 정보누락, 문서위주 관리 및 유선기반의 정보수집 등으로 인하여 다양한 현장의 환경변화에 실시간 대응이 곤란하여 능동적인 철도교량 유지관리 전략 수립에 제약을 갖고 있다. 본 연구에서는 유비쿼터스 기반의 철도교량 유지관리 정보운용체계 구축을 위한 실무 활용모형과 건설 생애주기의 통합 정보관리체계인 BIM (Building Information Modeling) 개념을 적용하여 유지관리 통합 운용모형을 제안하고 있다. 이의 개발 및 실무적 적용의 타당성 확보를 위해 설문분석에 의한 정량적 평가를 수행하였다. 최근 철도교량의 지능형 유지관리 운영체계가 확대될 것을 고려하면, 본 연구의 제안사항은 운영체계 구축을 위한 통합 프레임워크로 활용될 수 있을 것이다.

  • In the current 2D-based design, design reliability is lowered due to interference and inconsistency between plans, errors in drawings and quantities, etc. At the time of transition to BIM-based 3D design, it is necessary to expand the reliability and usability of BIM by eliminating these errors from the design stage through securing the quality of the BIM digital model. Therefore, in the railway infrastructure design stage, the quality management process and standards of the BIM digital model were defined and quality management index were developed. Based on the rule extracted from the quality management index, a pilot quality management was conducted in connection with the commercial Model-Checker rule, problems and improvement plans were derived, and a rule-based automated quality management plan was prepared.

  • The construction method using PC(Precast Concrete) has been widely used because the method can shorten the construction period and improve construction quality. In this paper, through the analysis of present design process for PC railway platform, design parameters on the geometry and properties were extracted and 3D information models for PC railway platform were constructed by the parametric modeling technique. Furthermore, the interface module was developed to link 3D models to the structural analysis/design sheet and database program using VBA(Visual Basic Application). This information model could be used in various areas including structural analysis and design, 2D drawing, quantity estimation and 4D simulation including clash detection.

  • BIM was introduced under the leadership of public institutions, and projects such as road, railway, and site creation, including BIM tasks, are currently being ordered. In addition, as the Ministry of Land, Infrastructure and Transport(MOLIT) is pushing for the full design of BIM, public institutions under its jurisdiction are also pushing for the full design of BIM. Full design of BIM means that all designs are done with BIM. Public institutions' BIM guidelines only require BIM deliverables, and there is a limited direction for the BIM design process to respond to traditional design approaches. Therefore, it is necessary to develop a BIM-based design process corresponding to the full design of BIM.

  • As the prefecture railroad construction accelerates, unmanned system's reliability and safety is increasing in demand. Accordingly, effective management of construction projects for the PM and SE techniques are being applied, with the introduction and use of PMIS computerized systems. Due to the construction of railways, from the start of PMIS research planning, design, procurement, to construction and commissioning, various expertise is being carefully gathered, and by integrating it into the unified budget ideas and processes, rational, efficient, organized, and manageable financial plans are developed for the computerized system. However, the current PMIS does not take into account the life-cycle. This study is to bring attention to the BIM smart BOM-based configuration management for life-cycle through the consideration for railway construction project management.

  • Based on real jobs, this study was carried out the Railway maintenance works in Taiwan. It hopes to use Geographic Information System(GIS) and Building Information Modeling(BIM) for changing the maintenance model from "post-damage repair" to "preventive maintenance". Accordingly, this research will build a Railway Repairing Database that installs all repair data. This database will also connect to GIS so that can be the source of analysis and statistic for repair paln. The main results of research are as follows: I. All data stored on cloud space that raises the ability to manage and plan on repair. II. Simplify the file work and increase the quantity of case data to the manager who can get more reliable source. III. The data offer objective judgment to avoid subjective argument. IV. Add the GIS information to improve the maintenance because of good analisis.
