1 Partnering & Pavement Preservation -A Contractors Perspective- AACE Meeting June 05, 2008 Mormon Lake, Arizona

2 Before you can Partner a Decision needs to be made as to what Pavement Preservation Strategy or Strategies will be Utilized!

3 Preventative Maintenance or Corrective Maintenance or Both What is Pavement Preservation?

4 Pavement Management System What do you do? Pavement Condition Index (PCI) Visual Inspection Maintenance Experience Rehabilitation - Performance History Initial Cost Dictates

5 What about the pavement condition?

6 Pre-maintenance; What about Patching?

7 Pre-maintenance; What about Crack Sealing?

8 Pavement Preservation – Scrub Seal Application

9 Pavement Preservation - Slurry Seal Application

10 Pavement Preservation - Micro Surface Application

11 Pavement Preservation - Chip Seal Application

12 Pavement Preservation - Hot Mix - Thin O/L Application

13 Pavement Preservation - Multi-layered System Application

14 Don’t Expect Miracles Pre-maintenance is Mandatory Consider Climatic Region (Const. Date) Binder Design Variables Mix Design Variables Construction Procedures (Details) Consider Traffic Conditions DON’T LET THE VARIABLES GET YOU DOWN!

15 Partnering Concepts Cost Issues/Considerations Lets Try to Reduce Initial Cost!

16 a) Inter-Agency Agreements b) Concurrent Bidding c) Tag-on Contracts d) Renewable Contracts e) JOC’s f) Specifications g) Early Bidding h) Project Scheduling i) Construction Criteria j) Materials Indexing

17 Inter-Agency Agreements Is this option possible? What are the liability issues for the lead agency?

18 Concurrent Bidding Practice Asphalt-Rubber Chip Seal Cost Comparison Example: Individual Project Cost - $ 4.87 per s.y. * Total square yards = 68,800 Partnering Project Cost - $ 4.23 per s.y. * Total square yards = 404,000

19 Tag-on Contract Communication - Tag-on Usage Unknown! * Lead Agency Price to all Participants Communication – Tag-on Usage Known! * Similar Pricing as Concurrent Bidding

20 Renewable Contracts and JOC’s

21 Specifications – Consistency! Early Bidding - Contractors are Hungary! Project Scheduling - Start and Cutoff Dates? Construction Criteria - Production Limitations! Materials Indexing - Equality at Bid Time!

22 Additional Cost Considerations Agency: Budget and Fiscal Year Project Size Pre Maintenance Costs Contractor: Asphalt Cement and Fuel (Big Cost) Mobilization Costs Scheduling & Construction (Mother Nature) Partnering Risks! Extended Warranties?

23 Did You Know: When PG Asphalt Cement Rises $ per ton, The Per Square Yard Cost of a Slurry Seal Rises- An Average of $0.14 Per Square Yard. The Per Square Yard Cost of a Micro Surface Rises- An Average of $0.22 Per Square Yard. The Per Square Yard Cost of a Chip Seal Rises- An Average of $0.25 Per Square Yard. The Per Square Yard Cost of a Hot Mix O/L Rises- An Average Cost of _______ Per Square Yard?

24 Discussion!
