Pavement Preservation - Multi-layered System Application
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!
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
Inter-Agency Agreements Is this option possible? What are the liability issues for the lead agency?
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
Tag-on Contract Communication - Tag-on Usage Unknown! * Lead Agency Price to all Participants Communication – Tag-on Usage Known! * Similar Pricing as Concurrent Bidding
Renewable Contracts and JOC’s
Specifications – Consistency! Early Bidding - Contractors are Hungary! Project Scheduling - Start and Cutoff Dates? Construction Criteria - Production Limitations! Materials Indexing - Equality at Bid Time!
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?
