T/UNP 710-2025 Municipal Road Engineering BIM Application Design and Delivery Specifications

Scope

Main technical content: This standard applies to all stages of the entire life cycle of municipal engineering, including planning, design, construction, and operation and maintenance. In terms of modeling, it clearly specifies the detailed requirements for model delivery content, format, and granularity at different application stages for various municipal engineering specialties (such as roads, bridges, tunnels, etc.). For example, in the construction phase, the BIM general plan layout should include the general plan layout model and walkthrough animation videos; the deliverables for structural deepening design should include the structural construction deepening model and model collision check files. In addition, the book also analyzes multiple BIM application cases in municipal engineering, providing practical reference for the application of the standard and helping municipal engineering achieve efficient and accurate construction and management with BIM technology. It also establishes rules, architectures, and unit specifications for model creation from scheme design to operation and maintenance. For example, all professional models need to uniformly adopt the current national geodetic coordinate system and elevation benchmark, and determine a unified project origin, units, and measurement system before creation.
