  1. MICHIGAN EXPERIENCE WITH WARRANTY WORK

  2. Warranty Program History • Why Warranties ? • Warranty Specifications • Experience & Lessons Learned

  3. Risk Transfer

  4. Pavement Warranty Summary (1996 – 2002) 473 = Capital Preventive Maintenance (CPM) 131 = Rehabilitation & Reconstruction (R&R)

  5. Warranty Contracts

  6. 2002 Warranties • Over 90% of CPM Program • Over 50% of R&R Program

  7. Warranty Duration • 2 or 3 Years (CPM) • 5 Years (R&R)

  8. 2-Year CPM Warranty • Chip seals • Micro-Surfacing • Crack Treatment • Concrete Joint Resealing

  9. 3-Year CPM Warranty • Non-Structural HMA Overlays • Cold Mill and HMA Resurfacing • Hot In-place HMA Recycling • Concrete Pavement Repairs

  10. 5-Year Rehab Warranty • Multiple Course HMA Overlays on - • Rubblized Concrete • Repaired HMA or Concrete • Crush & Shape Base

  11. 5-Year New & Reconstruct Warranty • HMA Pavements • Concrete Pavements

  12. Why Warranties ? • Quality Control (QC) Transferred to Contractors • Agency Staff Reduction • National Initiative from Method Specifications to Performance Specifications

  13. Contractor Responsibility for Materials and Workmanship Impacts Pavement Performance

  14. Contractor Benefits • Encourages Contractor Innovation • Enhances Contractor Knowledge About the Product

  15. Agency Benefits • Increased Pavement Performance • Reduced Pavement Life Cycle Cost

  16. Project Life Cycle Cost

  17. Current Condition 40% Percent of Network Pavement 19% 17% 10% 8% 6% (0-2) (3-7) (8-12) (13-17) (18-22) (23-27) (Years) Pavement Remaining Life Categories

  18. Yearly Distribution 8 Percent of Network Pavement 23 1 3 13 18 (0-2) (3-7) (8-12) (13-17) (18-22) (23-27) (Years) Pavement Remaining Life Categories

  19. Ideal Condition Percent of Network Pavement 20% 18% 18% 17% 16% 11% (0-2) (3-7) (8-12) (13-17) (18-22) (23-27) (Years) Pavement Remaining Life Categories

  20. Warranty Specifications

  21. Quality Data • Specification Development • Project Monitoring

  22. Spec Development Process • Performance Measures Must Be Linked to Warranty Length • Performance Thresholds Must Be Based on Actual Pavements • Contractor is Involved as Partner

  23. Warranty Spec Components • Initial Acceptance • Warranty Bond • Rights and Responsibilities • Performance Thresholds • Corrective Action • Conflict Resolution Process

  24. Initial Acceptance • Form Signed by Department and Contractor • Acceptance Date of Construction • Linked to “Open to Traffic” • Linked to Pavement Acceptance • Starts Warranty Period

  25. Bond CPM 100% of the warranted work R&R 5% of the contract amount or fixed $ amount

  26. Rights and Responsibilities of the Department • Approve Materials, Methods and Schedule for Corrective Work • Perform Routine Maintenance • Involve Third Party for Emergency Repairs • Notify Contractor when Pavement Condition Exceeds the Performance Thresholds

  27. Rights and Responsibilities of the Contractor • Provide Written Work Plan for Corrective Action • Follow Agency Permit Process • Complete All Corrective Work Before Warranty Expires

  28. Performance Thresholds • Condition Parameters • Segment Length • Contractor Caused Condition

  29. General Condition Parameters (Asphalt) • Transverse Cracking • Longitudinal Cracking/Open Joint • De-Bonding • Raveling • Flushing • Rutting • Ride Quality

  30. Flushing

  31. Rutting

  32. Conflict Resolution Process • Five Member Team • Two Department • Two Contractor • One Mutually Selected • Never Invoked To Date

  33. Warranty Call Backs • CPM < 5% • Repair Work • Cash Settlement • R&R < 2% • Repair Work

  34. Experience After 5 Years • Reduced Agency Inspection Costs • Unknown “Actual” Overhead Cost • No Effect on Bid Costs • Unknown Gains in Remaining Service Life • Improved Workmanship with some Contractors • Premature Distress not Eliminated • Transfer of Risk is in Process

  35. Lessons Learned • Proper Project Scoping is Key • Documentation Becomes More Important • Need for Tougher Pre-Qualification Standards for Contractors • Agency Responsibility has Shifted • Some Contractors won’t Bid Warranty Work • Warranties are here to stay
