I ndiana Bridge Inspection QA/QC Procedures Discussion Topics INDOT Quality Assurance Procedures/Scope Focus Moving Forward/Reference Materials Review of Changes to the Bridge Inspection Requirements
I ndiana Bridge Inspection QA/QC Procedures Need for QA/QC Procedures? Federal requirement for QA/QC ♦ 23 CFR 650.313(g) Quality Control and Quality Assurance requires each state to assure that systematic Quality Control (QC) and Quality Assurance (QA) procedures are being used to maintain a high degree of accuracy and consistency in the inspection program Without QA/QC procedures in place, FHWA would find INDOT non-compliant, NBIS Metric #20 INDOT designated Beam, Longest & Neff (BLN) as Quality Assurance Officer (2011 – Present)
I ndiana Bridge Inspection QA/QC Procedures Goal of QA/QC Procedures? To Help Ensure: ♦ Accuracy ♦ Consistency ♦ A Quality Product ♦ Public Safety ♦ Maintenance and Repairs ♦ Prioritize Recommended Work ♦ Identify Training Needs
I ndiana Bridge Inspection QA/QC Procedures QA/QC Procedures review is the Internal Review conducted from within an inspecting agency Focuses on at-risk bridges Office and field reviews Reviewed by Inspection agency – INDOT or Inspection Consultant
I ndiana Bridge Inspection QA/QC Procedures QA/QC Procedures review is the External Review conducted from outside an inspecting agency Independent oversight reviews to focus on at-risk bridges Reviews by INDOT and BLN
I ndiana Bridge Inspection QA/QC Procedures Quality Assurance Procedures Quality Assurance Reviews ♦ QA/QC Procedures – Part 2 Indiana Bridge Inspection Manual (IBIM) ♦ INDOT Control Bridge – 2 year cycle ♦ BLN and BFS Independent Oversight Review Bridge File Review County Load Rating Verification Reviews
I ndiana Bridge Inspection QA/QC Procedures Quality Assurance Review Scope and Changes Quality Assurance Review Scope ♦ All reviews and forms in accordance with QA procedures per IBIM Part 2 ♦ Bridge reviews as selected by INDOT ♦ 24 Bridges chosen for team leaders who did not attend control bridge, per IBIM Part 2, Section 3.2 Changes in Scope ♦ QA form changes, IBIM Part 2, Appendix ♦ Office reviews revised to bridge file reviews ♦ Reviews based on Metric comparison and not a score
I ndiana Bridge Inspection QA/QC Procedures Quality Assurance Review Scope and Changes Quality Assurance Form ♦ Metric Comparison vs. Scoring
I ndiana Bridge Inspection QA/QC Procedures Independent Oversight Review Independent review of inspection data and findings for accuracy Selected bridges based on posting, condition ratings, need for improvements, and Team Leader Compared QA Officer results to original inspection results and notes Reviews Conducted on District and Consultant Team Leaders throughout the state
I ndiana Bridge Inspection QA/QC Procedures Bridge File Review Review of bridge files for accuracy and completeness Selected bridges by INDOT search of files for known and suspected inaccuracies Bridge file checked for required items as outlined in the AASHTO Manual for Bridge Evaluation, Section 2 Reviews of County and District bridges
I ndiana Bridge Inspection QA/QC Procedures Load Rating Verification Review Independent Review of load rating computations for county bridges Selected bridges based on INDOT query, consultant, team leader, condition ratings, and load posting QA Officer performed field inspection and load rating Compared QA Officer load rating to consultant load rating Results reviewed based on QA form and NBIS Metric 13
I ndiana Bridge Inspection QA/QC Procedures Focus Moving Forward: Determined from findings from all QA reviews Based on reoccurrence of similar comments and procedures ♦ Bridge File ♦ Critical Findings ♦ Load Rating ♦ Fracture Critical Reports
I ndiana Bridge Inspection QA/QC Procedures Bridge File Documentation IBIM Part 1, Section 2.5 and 4.1 Official bridge file is the central database information in BIAS, used to report NBI data and supplemental state information to FHWA Historic data and updated bridge inspection data Other attachments, past reports, load rating summary, correspondence, Scour Plan of Action reports, and special reports such as Underwater, Fracture Critical, Special Detail Indiana Bridge Inspection Application System (BIAS): https://indot-it.bentley.com/login.aspx
I ndiana Bridge Inspection QA/QC Procedures Bridge File Documentation / Reports Note enough deficiencies to provide justification for condition rating. Verify deficiencies noted are consistent between sketches, comments, and executive summary Bridge deck rating for adjacent box beam bridge without deck to be based on beam condition not wearing surface condition Approve bridge data within 60 days of inspection Use text and abbreviations that are easy to follow
I ndiana Bridge Inspection QA/QC Procedures Critical Findings Structural or safety related deficiency that requires immediate follow-up inspection or action IBIM Part 1, Section 5.2 ♦ All bridges - Notification to State Program Manager of critical finding and document finding in BIAS, IBIM 5.2.2 ♦ Documented in BIAS under Maintenance Tab
I ndiana Bridge Inspection QA/QC Procedures Critical Findings IBIM Part 1, Section 5.2 ♦ Locally owned bridges – Report to ERC and State Bridge Inspection Program Manager ♦ Inspection agency to document action taken in BIAS ♦ Take action in reasonable time ♦ Provide closeout documentation in BIAS to closeout critical finding report
I ndiana Bridge Inspection QA/QC Procedures Load Ratings IBIM Part 3 When in the Field…… ♦ Take extra time in field to verify structure member sizes, bridge dimensions, and section loss ♦ Document section loss and remaining section ♦ Verify condition at each phase of inspection, including annual inspections
I ndiana Bridge Inspection QA/QC Procedures Load Ratings
I ndiana Bridge Inspection QA/QC Procedures Load Ratings When in the Office….. ♦ If significant deficiencies or change in condition visible, calculate rating quickly and recommend load posting changes ♦ Verify remaining section or section loss noted matches load rating calculation ♦ Include shear and moment in load rating calculations ♦ Verify load rating calculations or summary are signed and include Load Rating Engineer(LRE) information
I ndiana Bridge Inspection QA/QC Procedures Load Ratings When in the Bridge File… ♦ Inspection agency to make sure load rating information added to bridge file in BIAS, does not have to include all pages of the calculation ♦ Make sure load rating matches BIAS data, must unapproved initial reports after load rating report approved ♦ Make recommendations for posting changes if needed. Remember to recommend advance posting signs.
I ndiana Bridge Inspection QA/QC Procedures Fracture Critical Reports IBIM Part 4 ♦ Develop Fracture Critical or Special Detail reports ♦ Providing fatigue categories and ratings for all fracture critical members at connections Although this ♦ Members within 12” member is not Fracture Critical, this of connection portion is within the limits of a fracture critical connection Fracture Critical Member (Tension) Fracture Critical Limits of Fracture Critical Member (Tension) Connection (12”)
I ndiana Bridge Inspection QA/QC Procedures Fracture Critical Reports IBIM Part 4 ♦ Fracture Critical Reports to provide condition ratings and fatigue categories for floor beams at connections ♦ Need to report section loss ♦ Need to report cracks or holes
