The Tokaido Shinkansen high-speed Japanese rail line excels globally in safety, punctuality, and frequency. This project aims to transform infrastructure maintenance using BIM. Although Japan rail owners are adopting BIM, efforts remain siloed across teams and lack integrated optimization. Rail maintenance requires ongoing inspection, diagnosis, action, and documentation. Seamless data handover is essential to reducing lifecycle costs, but information often stays locked in noninteroperable systems. JR Central addressed this by piloting a common data environment and object library for embankments, following ISO 19650-based information management. Interoperability was ensured through openBIM standards such as Industry Foundation Classes (IFC) and bSDD (buildingSMART Data Dictionary), which unify object definitions and data formats. Revit and Construction Cloud, powerful BIM tools, were also adopted to enhance authoring consistency and collaborative workflows. This initiative unlocks a new era in infrastructure maintenance—firmly grounded in interoperability.
