How does an inspector determine the required maintenance actions from NBIS findings?

• A. Based on severity, risk assessment, redundancy, and expected life of the element.
• B. Based on inspector mood.
• C. Based on alphabetical order.
• D. Based on fiscal year budget.

Answer: (A)

The main idea is to use a risk-based assessment of the finding to decide what maintenance is needed. Inspectors look not just at how bad a defect is, but at what risk it creates for public safety, how much redundancy the bridge has (whether other elements or paths can carry the load if this one is out of service), and how long the element is expected to last. This combination helps determine the appropriate action—repair, retrofit, or replacement—and how urgent it should be. If a deficiency is severe and the structure has little alternative load paths, action is prioritized and may be required soon. If there’s good redundancy and the element has significant remaining life, the action can be scheduled later. Budget or mood aren’t used to determine these actions; safety-focused, data-driven criteria drive the decisions.
