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.

The Cost Estimation Guidance is referred to in Appendix B of the department's Notes on Administration (NOA) for Land Transport Infrastructure Projects for the 2014 to 2015 financial year to the 2018 to 2019 financial year.

Guidance notes

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.

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 Notes on Administration (NOA), which seek Australian Government funding for road and rail infrastructure projects.

More information on the Notes on Administration (NOA) and the associated National Partnership Agreement can be found at Investment Road and Rail Program.

Published guidance notes

The following Guidance Notes have been published following a thorough consultation process, where applicable, and are available now for download:

  • Guidance Note – Overview, Version 1.0, August 2018 PDF: 1.6 MB
  • Guidance Note 1 — Project Scope, Version 1.0, March 2017 PDF: 354 KB ReadSpeaker

Upcoming guidance notes and future consultation

It is anticipated that Guidance Notes 3A and 4 will be published on this website before the end of 2018.

While the department does not intend to expand its cost estimation guidance beyond the six key components at this stage, further notes on additional topics may be developed in future. The department will undertake a process of consultation with any future guidance note prior to final publication.
