SNBI Data Validation Logic - Version 1.1
The release version of the SNBI data validation module is used for validating National Bridge Inventory (NBI) data in preparation for the first submittal of NBI data in accordance with the SNBI on March 15, 2026.
The data validation module identifies three types of errors:
- When critical errors are found by FHWA in the annual data submittal, the data must be corrected and resubmitted within 15 business days.
- General (non-critical) errors fall into two categories:
- Minor or isolated errors may be corrected at any time, but not later than the following year’s data submittal.
- Widespread errors of similar type may indicate larger issues with the data and may require additional analysis to determine a timeline for correction.
- Flags should be reviewed to determine if they are true errors. If corrections are needed, the data may be corrected at any time but not later than the following year’s data submittal.
For the 2026 and 2027 data submittals, datasets may contain temporary codes as well as null values for data items that were not collected under the Coding Guide. FHWA will issue guidance prior to the 2026 data submittal that will specifically address the expectations for data quality and completeness. As noted in FHWA’s May 25, 2022, memorandum titled Implementation of the Specifications for the National Bridge Inventory, temporary codes will not be accepted for the 2028 data submittal or thereafter.
