Element-Level Bridge Inspection & Condition States

3 PDH · Course no. BI-201 · Author: Michael Craig, PE

How element-level data works under the NBIS and SNBI: picking the right elements and units, distributing quantities across Condition States 1–4, tying defects to condition states, coding protective systems with parent numbers, and the QC checks that catch errors before submittal.

Learning objectives

• Explain the federal basis for element-level data (23 U.S.C. 144, 23 CFR 650.315 and 650.317)
• Distinguish SNBI 9–0 component ratings from element condition states
• Identify NBEs, BMEs and agency-developed elements
• Distribute quantities across CS1–CS4 so they sum to the total
• Relate common defects to condition states and code protective systems
• Apply QC/QA checks to element data
