buildingSMART International (bSI) is a neutral, international, independent, non-profitorganization aiming at servicing BIM LCC. This organization was set up in 1994, has sub-branches in North America, Europe, Australia, Asia and other countries in mid-east Asia, made tremendous contribution of global BIM technology development, had important influence in international architecture informatization field.buildingSMART regulation is approved and published by bSI. By using this format, the achievement of railway BIM data storage has silicified China’s important role in railway BIM international standard compilation. Also, it can appeal to more colleagues, collect supplementary opinion, improve the adaptability of Chinese railway BIM standard, so that laying a better foundation for it upgrading as an international standard.
