2. Quality Assurance - Definition AASHTO R10 & TRB Circular E-C173 Quality Assurance –All thoseplanned and systematic actions necessaryto provide confidence that a product or facility will perform satisfactorily in service …

3. Applicability of 23 CFR 637 • Applies to projects on the NHS • State administered and locally administered • Including Design-Build - 23CFR637.207(b) “All provisions of 637.207(a) are applicable to Design-Build projects and other alternative contracting methods.” • Non-NHS projects • Many States apply same QA procedures as NHS

4. Core Elements of a Quality Assurance Program

5. Core Elements of a QA Program Quality Assurance Agency Acceptance Quality Control Independent Assurance Dispute Resolution Laboratories Personnel

6. Agency Acceptance • All acceptance activities must be carried out by the Agencyor their “Designated Agent” • Agency independently performs: • Random (Verification) Testing ( Materials) • Inspection ( Workmanship)

7. Acceptance Program • Acceptance program. All factors that comprise the Agency determination of the quality of the product as specified in the contract requirements. These factors include: • verification sampling, • testing, • inspection

8. Acceptance Function • Acceptance is not focused on directing the methods used to achieve conformance • The primary objectives of agency acceptance are: • Measure the Quality of all materials producedand placed by the contractor • Determine the corresponding paymentthe contractor should receive

9. Acceptance Function • Quality measurement is achieved through three general acceptance activities: • Monitoring the adequacy of contractor QC activity • Performing acceptance inspection to identify visually deficient work • Performing Acceptance sampling and testing for key quality characteristics • Agency obtains information to confirm that all products meet the specified quality level

10. Independent Assurance - IA Independent Assurance- “Activities that are an unbiased and independent evaluation of all the sampling and testing procedures used in the Quality Assurance Program”

11. Scope of IA Activities Independent Assurance activities: • Provide an assessment of personnel proficiency and equipment for both agency and contractor

12. Independent Assurance – IA (cont.) • Performed by Agency or Designated Agent personnel who are not directly responsible for project Acceptancesampling and testing • Provides periodic independentevaluation of QC and Acceptance personnel and their equipment • Not used to make a determination of work quality or acceptability

13. Definition Contractor Quality Control Quality Control - QC - “The system used by a Contractor party to monitor, assess and adjust their production or placement processes to ensure that the final product will meet the specified level of quality.”

14. Contractor Responsibility for Quality Control QC is the responsibility of the Contractor The party producing or placing the product is in the best position to exercise Quality Control

15. Scope of Quality Control Activities • Contractor’s QC system should address: • Materials production processes • Materials transportation and handling • Field placement procedures • Calibration and maintenance of equipment • Activities (sampling, testing and inspection) to maintain each process in control • Means to make timely adjustments and corrections

16. Contractor QC Operating Documents Quality Control Plan - A project specific document prepared by the contractor which identifies QC personnel and procedures that will be used to maintain production and placement processes in control and meet theagency specification requirements.

23. Materials Testing Dispute Resolution Dispute Resolution- The procedure used to resolve discrepancies between the Agency’s Acceptance and Contractor’s QC testing results that could impact payment. Dispute Resolution system required when QC results used in Acceptance decision.

24. Responsibility for Dispute Resolution Can be performed within the DOT Use of accredited third party laboratory can be used.
