T/CRBIM 005-2017 Railway Engineering Information Modeling Expression Standard (Version 1.0)
Basic Information
Scope
Main technical content: This standard is mainly used to standardize the expression of railway engineering information models and coordinate the way in which various parties involved in railway engineering identify railway engineering information. It is applicable to the establishment, transmission, and use of railway engineering information models during the design and construction of railway projects, as well as to the coordination among various professional fields and the collaboration among all parties involved in engineering design. This standard covers and involves 21 professional fields, including railway bridges, tunnels, track beds, station yards, rail tracks, catenary systems, traction substations, power supply, communication, signaling, information, natural disasters and foreign object intrusion detection, land use, landscape, comprehensive inspection and maintenance, water supply and drainage, locomotives, vehicles, EMUs, and environmental protection. The content includes general principles, terminology, basic provisions, naming rules, model geometric expression levels, model splitting and combining, model lightweighting, view expression, external references, delivery content and form, and design output delivery format and rendering materials.
