Cost Estimation Guidance

The Department is in the process of developing a series of cost estimation Guidance Notes which, in aggregate, will constitute the Cost Estimation Guidance referred to in Appendix B to the Department's Notes on Administration for Land Transport Infrastructure Projects 2014–15 to 2018–19 (the NOA). The Cost Estimation Guidance will provisionally comprise the following key components:

  • Overview
  • Guidance Note 1 (Project Scope)
  • Guidance Note 2 (Base Cost Estimation)
  • Guidance Note 3A and 3B (Probabilistic and Deterministic Contingency Estimation)
  • Guidance Note 4 Outturn (Escalation) Cost Estimation

It is not intended that the Cost Estimation Guidance be available as a printed bound document. Rather it will be published on the Department's website in PDF form, both as individual components, as well as a single consolidated document, that can either be read online or downloaded for subsequent use.

The version date of each component of the Cost Estimation Guidance will be listed on the webpage and will also appear as Appendix A Current Component Version Status–Cost Estimation Guidance to the Cost Estimation Guidance Overview component.

The Guidance will outline the principles that must be followed by proponents in preparing cost estimates accompanying Project Proposal Reports, submitted in accordance with the NOA, which seek Australian Government funding for road and rail infrastructure projects. The NOA and the associated National Partnership Agreement is available at the following link:
