What is NBIS's role in maintenance planning?

• A. Provide a basis for repairs, monitoring, and reporting.
• B. Only archived historical records.
• C. Not used for maintenance decisions.
• D. Replaces all independent inspections.

Answer: (A)

NBIS is the national data system that stores bridge information such as inspection results, condition ratings, inventory data, and maintenance history. That information provides the basis for choosing what needs repairs, what should be monitored over time, and how progress is documented in reports. It isn’t just a repository of old records; it actively supports maintenance planning by guiding prioritization, monitoring plans, and reporting to stakeholders. Inspections are still performed independently, and NBIS records their findings to inform decisions rather than replacing the inspections themselves. While NBIS data is essential, maintenance decisions are made by combining this information with safety considerations, funding, and design requirements.
