Overview of Bridge Program Performance Measures and Compliance Indicators

This document provides an overview of the performance measures and compliance indicators for the Bridge Program overseen by ODOT and FHWA. It outlines various performance indicators related to bridge condition, including the percentage of structurally and functionally deficient bridges on NHS and non-NHS systems. It also details compliance indicators that track the completion of routine, fracture critical, and underwater inspections within established cycles. Maintenance performance measures highlight urgent and critical unresolved recommendations. Additionally, it discusses future changes to performance indicators based on compliance review results.

  1. Bridge Program Performance Measure Overview ODOT/FHWA Stewardship Oversight Committee Meeting Gary Bowling (ODOT) and Tim Rogers (FHWA) May 29, 2012

  2. Bridge Program Area • FHWA Lead – Tim Rogers • ODOT Lead – Bruce Johnson • “Bridge” Performance and Compliance Indicators address the following: • Performance Indicators1 &2: Bridge Condition • Compliance Indicators 3 thru 5: Bridge Inspection • Performance Indicators 6 & 7: Bridge Maintenance

  3. Bridge Condition Performance Indicators • Percent of NHS bridges rated structurally and functionally deficient as measured by deck area • Percent of Non-NHS bridges rated structurally and functionally deficient as measured by deck area • Structurally Deficient = Structural Components are in “Poor” or worse condition or the “Structural Evaluation” or “Waterway Adequacy” is intolerable. • Functionally Deficient = Deck geometry, load carrying capacity, clearance, or approach roadway alignment no longer meets the criteria for the system.

  4. Bridge Condition Performance Indicators • Percent of NHS Bridge Deck area rated structurally and functionally deficient

  5. Bridge Condition Performance Indicators • Percent of Non-NHS Bridge Deck area rated structurally and functionally deficient

  6. Bridge Inspection Program Compliance Indicators • Percent of routine bridge inspections completed within the established bridge inspection cycle • 24 month inspection cycle • Percent of fracture critical bridge inspections completed within the established bridge inspection cycle • 24 month inspection cycle • Percent of underwater bridge inspections completed within the established bridge inspection cycle • 60 month inspection cycle

  7. Bridge Inspection Program Compliance Indicators • Percent of bridge inspections completed within the established bridge inspection cycle • Routine Inspections • Fracture Critical • Underwater

  8. Bridge Maintenance Performance Indicators • Number of “urgent” maintenance recommendations not resolved after 12 months • Needs to be repaired ASAP to address a specific traffic safety concern. • Structural component rated in Poor Condition • Number of “critical” maintenance recommendations not resolved after 12 months • Needs to be repaired to prevent structure from being load posted. • Structural Component rated in Serious Condition

  9. Bridge Maintenance Performance Indicators • Number of Urgentmaintenance recommendations not resolved after 12 months • Number of Critical maintenance recommendations not resolved after 12 months

  10. Future Changes to Bridge Program Performance Indicators? • Bridge Inspection Program Compliance Indicators • Incorporate the results of the annual National Bridge Inspection Program (NBIP) compliance reviews: • % of NBIP Metrics in Satisfactory Performance Level • % of NBIP Metrics in Actively Improving Performance Level • % of NBIP Metrics in Unsatisfactory Performance Level • Delete the following: • Percent of routine bridge inspections completed within the established bridge inspection cycle • Percent of fracture critical bridge inspections completed within the established bridge inspection cycle • Percent of underwater bridge inspections completed within the established bridge inspection cycle

  11. Future Changes to Bridge Program Performance Indicators? • Bridge Inspection Program Compliance Indicators

  12. Bridge Program Performance Measure Overview • Questions?
