T/CQGBAIA 021-2025 Automatic Procedural Checking Specification for Construction Quantity of BIM Model in Project Costing

Scope

The main technical content includes: the method of establishing the corresponding relationship between BIM model components and measurement rules; the standardization of model attribute parameters and data structure specifications; the logic of quantity extraction and the identification rules of model components; the process design of quantity verification, the setting of verification nodes, and the division of responsibilities; the error identification mechanism and determination threshold of automatic verification algorithms; the identification strategies for common error types (such as duplicate measurement, component omission, attribute errors, etc.); automatic verification methods based on model comparison, graphic element analysis, and rule engines; and the visual presentation, traceability, and reporting generation standards of verification results. The standard emphasizes adaptability to actual engineering scenarios and compatibility with software platforms, strengthens process controllability and result traceability, and lays a foundation for digital review of the entire engineering cost process.
