Bridge Program Quality Assurance (QA) Reviews

To ensure compliance with the National Bridge Inspection Standards (NBIS) two types of reviews are performed on local agencies’ bridge inspection programs.

Quality Assurance Reviews

  • QA reviews are scheduled for agencies owning bridges listed on the National Bridge Inventory (NBI) on a three year cycle.
  • WSDOT Local Agency Bridge Engineer works with agency personnel to evaluate the program’s strengths, weaknesses and makes suggestion to correct any deficiencies.
  • A close-out conference is help to discuss the findings and a report is sent to the local agency.

National Bridge Inspection Program Reviews

  • FHWA coordinates with the WSDOT Local Agency Bridge Engineer to conduct National Bridge Inspection Program reviews for NBIS compliance.
  • Specific areas of interest are load ratings and scour analysis.
  • Recommendations for improvements are given and a report is filed.
  • If the state or local agency program is deemed out of compliance with NBIS, a request to achieve compliance is issued.
  • If an agency fails compliance, federal funds can be withheld until compliance is achieved.
