Abstract
Building Information Modeling (BIM) can act as a solution to improve various difficulties faced in the construction industry. BIM is expanding into infrastructure facilities for integrated information management, productivity improvement, and risk management. There are many cases where BIM is applied to buildings with horizontal and linear characteristics, but the infrastructure is different from the method of applying BIM to buildings with vertical characteristics. Using premanufactured libraries in BIM-based design can shorten the design time and simplify the design method, thus increasing the 3D design productivity. This paper develops BIM prototype libraries based on the standards from the Ministry of Land, Infrastructure, and Transport (MOLIT) of South Korea for railway infrastructure. BIM tools such as Civil 3D, Revit, and AECOsim were used by reflecting the characteristics of each facility, and the libraries, with a total of 762 types in 363 files, were constructed. The specifications were created by linking the common and facility-specific attribute items to the libraries. The result of the test modeling using the developed library showed significant productivity improvement, such as an average difference of 38.2% was observed for roadbed modeling and a mean difference of 50.2% for bridge modeling.
Highlights
Building information modeling (BIM) has been recognized as a tool for overcoming the difficulties faced by the architecture, engineering, construction, owner, and operator (AECOO) industries [1].As well-prepared and information-abundant BIM models support visual shapes and the management of schedules (4D) and costs (5D), the use of BIM can facilitate the construction process [2]

BIM is a building-oriented technology, as the term denotes, and is referred to as civil information modeling (CIM) when it is applied to the civil engineering field
Summary
Building information modeling (BIM) has been recognized as a tool for overcoming the difficulties faced by the architecture, engineering, construction, owner, and operator (AECOO) industries [1].As well-prepared and information-abundant BIM models support visual shapes and the management of schedules (4D) and costs (5D), the use of BIM can facilitate the construction process [2]. Building information modeling (BIM) has been recognized as a tool for overcoming the difficulties faced by the architecture, engineering, construction, owner, and operator (AECOO) industries [1]. BIM and CIM, have different modeling processes. BIM is created perpendicular to the floor, and it is not significantly associated with the surrounding terrain. For infrastructures such as roads and bridges, the cross-section is defined, and horizontal expansion is performed along the designated path for modeling. Aside from these differences, BIM and CIM have similar data management and exchange systems [3]
