What is a typical NBIS inspection sequence?

• A. Plan and safety briefing, access structure, perform visual inspection of components, document with notes and photos, complete NBIS forms, plan follow-up actions.
• B. Inspect first, then plan, then document, then finalize.
• C. Plan, purchase materials, perform repairs, and sign off.
• D. Only document with photos; no planning.

Answer: (A)

The main idea here is that NBIS inspections follow a safe, organized workflow that ensures thorough observation and proper documentation. You start with planning and a safety briefing to define scope, identify hazards, and ensure the right PPE and traffic controls are in place. Next comes accessing the structure safely so you can reach all required areas. With safety in place, you perform a systematic visual inspection of the bridge components—deck, superstructure, substructure, bearings, joints, and other NBIS-relevant features—while noting conditions and capturing photos to document what you observe. After fieldwork, you complete the standardized NBIS forms to record findings in a consistent, regulatory-compliant way. Finally, you plan follow-up actions, such as recommended repairs, additional inspections, or monitoring, based on the observed condition and NBIS criteria.

This sequence is best because it emphasizes safety first, then access, then observation, followed by formal documentation and actionable planning. The other approaches skip essential steps or mix in maintenance activities (like repairs or purchases) that aren’t part of the NBIS inspection process, or rely solely on photos without the necessary planning and form completion.
