21 China Railway BIM Standard
• China Railway BIM Standard is composed of three parts: • Part 1: Railway BIM Classification Standard • Refer to ISO 12006-2 • Was completed in December 2014. • Part 2: Railway BIM Data Standard • Based on ISO 16739 • A draft version was accomplished in June 2015. • The public version was expected to be available in December 2015. • Part 3: Railway BIM Delivery Standard • Based on ISO 29481, started in July 2015, expected to be available in 2016. • Led by the Third Railway Survey and Design Institute & Tsinghua University, all direct members involved.
