How do I work out for a network of unsealed roads the expenditure and resources required to meet certain service levels so that our organization can see the impacts quickly at budget time?
- Step 1. Break-up your road network into similar roads using a road classification system. Eg. Arterial, Collector, Local and Property Access.
- Step 2 . Summaries the lengths of each road class in a spreadsheet.
- Step 3. Determine your standard costs $/km for grading and resheeting works for each different road class.
- Step 4. Determine your service levels. For example, the grading frequencies and resheeting renewal % for each class.
- Step 5 . Set-up a calculations
- Total grading cost = Length of Road Class x $/km (Grading Std) x Frequency
- Total resheeting cost = Length of Road Class x $/km (Resheeting) x % Renewal (4-8% normally)
- Step 6. Take model to Council and change the services levels to show the required expenditure to meet certain service levels.
This is basically how it is completed. If you would like to use a Excel Model that has already been set-up click below.
