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
Pavement Remaining Life Categories Percent of Network Pavement (0-2)(3-7)(8-12)(13-17)(18-22)(23-27) 19% 10% 40% 8% 6% 17% Current Condition (Years)
18
Yearly Distribution Pavement Remaining Life Categories Percent of Network Pavement (3-7)(8-12)(13-17)(18-22)(23-27) (Years) (0-2) 1 3 8 13 18 23
19
Ideal Condition Pavement Remaining Life Categories Percent of Network Pavement (0-2)(3-7)(8-12)(13-17)(18-22)(23-27) (Years) 11% 17% 20% 18% 16%
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
31
Flushing
32
Rutting
34
Conflict Resolution Process Five Member Team Two Department Two Contractor One Mutually Selected Never Invoked To Date
35
Warranty Call Backs CPM < 5% Repair Work Cash Settlement R&R < 2% Repair Work
36
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
37
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
38
