The "High-reliability Interoperability for Railway Stations" project, (aka “HIRS”), initiated by the buildingSMART International Railway Domain, aims to standardize railway station information through cross-domain collaboration, to solve the information silo problem and asset management challenges.

This survey has been designed to better understand the characteristics and data exchange demands of railway station projects, as well as the application of existing Industry Foundation Classes (IFC) and the buildingSMART Data Dictionary (bSDD).

We invite you to participate in this survey; your feedback is important for our research and the railway industry’s development.
