  "description": "This crop is the continuation of the General Notes and the Design Data block from a bridge structural drawing sheet (sheet page 2), covering pile driving, vibration monitoring, steel H-pile material, and smooth dowel bar installation notes, alongside a Design Data table listing specifications, live load, concrete classes/strengths, reinforcement and prestressing steel grades. A small partially-illustrated table for Bent Number vs. Pile Tip Elevation is shown at top center with placeholder/illegible values, annotated by a green callout requesting a table be added for elevations 2 feet above the estimated pile tip elevations."
