Review of Changes to the Bridge Inspection Requirements


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)


Goal of QA/QC Procedures?

To Help Ensure:♦ Accuracy

♦ Consistency

♦ A Quality Product

♦ Public Safety

♦ Maintenance and Repairs

♦ Prioritize Recommended Work

♦ Identify Training Needs


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


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


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


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

Quality Assurance Review Scope and Changes


Quality Assurance Review Scope and Changes Quality Assurance Form

♦ Metric Comparison vs. Scoring


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


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


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


Determined from findings from all QA reviews

Based on reoccurrence of similar comments and procedures♦ Bridge File

♦ Critical Findings

♦ Load Rating

♦ Fracture Critical Reports

Focus Moving Forward:


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


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


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


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


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


Load Ratings


Load RatingsWhen 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


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.


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

♦ Members within 12” of connection

Fracture Critical Member (Tension)

Limits of Fracture Critical Connection (12”)

Although this member is not

Fracture Critical, this portion is within the limits of a fracture critical connection

Fracture Critical Member (Tension)


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


Fracture Critical Reports Fatigue Details – IBIM Part 4, Appendix B

Sample Report – IBIM Part 4, Appendix A
