2. Compile an asset inventory that provides the base data for calculating asset values for all road infrastructure assets.

3.Calculate the initial value of the road infrastructure assets. This involves the following:

  • Calculating the gross replacement cost for each asset within a group or subgroup

4. Calculate the consumption of the assets, which involves the following:

  • Calculating in-year depreciation
  • Assessing for in-year impairment and calculating loss in value when required

5. Calculate the depreciated replacement cost, which involves the following:
