In Design Checks, which is a valid source for criteria files?

• A. Standard ASHTO Criteria Files
• B. Revit Models
• C. Excel Spreadsheets
• D. CAD Block Libraries

Answer: (A)

Design checks rely on criteria files to encode the rules and limits used to evaluate a roadway design. The Standard ASHTO Criteria Files are the official source that provides these thresholds in line with recognized highway design guidelines, covering aspects like sight distance, alignment, superelevation, cross-section features, and lane/offset requirements. Using these files allows the design check engine to compare the model against consistent, nationally accepted standards, yielding reliable, comparable results across projects. Revit models aren’t used to supply design-check criteria since they belong to BIM data for buildings rather than highway design rules. Excel spreadsheets or CAD block libraries aren’t the built-in source the checks reference for rule definitions; they may store related information, but they don’t serve as the criteria files that drive the checks.
