A Development of libraries for BIM Design of railway infrastructure and Establishment of sharing system

Abstract

As part of the digitalization efforts in the construction industry, the mandatory implementation of Building Information Modeling has been progressing rapidly. This study conducted research to establish a shared system for accumulating and expanding data, aiming to secure an ample library throughout the life cycle. The research was conducted in three directions: the development of design libraries, the configuration of open properties, and the establishment of an expandable shared system. The design library, based on railway standards, analyzed the quantity and information of useful objects, resulting in the development of 741 items suitable for the design phase with a LoD 300. The properties of the libraries were configured in an open format to operate in the sharing system, providing design-specific parameters and information reflective of design details. In particular, the sharing system was established with an expandable concept, integrated with the delivery system to allow for the addition of new data, expanding the objects within the existing data bank. Initially, the facility classification system PBS was integrated with railway standard codes. Considering the WBS and ISO system to enable stepwise expansion throughout the lifecycle, a sequential numbering system was implemented in an expandable format. Designing data management properties to prevent duplication and loss of data, a database for the delivery system was developed. A program was written and implemented to enable search, sharing, and additional expansion. The scalable shared system and open design libraries will contribute to consistent information management and library augmentation throughout the design, construction, and maintenance lifecycle.
