Guide to Project Evaluation Part 8: Examples


Publication no: AGPE08-06 Pages: 49
Published: 30 June 2006

Part 8 of the Guide to Project Evaluation (the Guide) presents worked examples demonstrating appropriate use of project evaluation techniques applied to a selection of infrastructure upgrading projects commonly faced by practitioners. Some of these examples are updated and expanded from the Austroads Benefit Cost Analysis Manual (1996), and are intended to demonstrate the benefit-cost analysis (BCA) methodology and techniques described in Part 2. Each of the nine worked examples (flood mitigation, sealing and realignment, bridge maintenance, ferry upgrade, blackspot evaluation, timing of project, bus priority, town bypass and road widening) is linked to an executable Excel spreadsheet showing all relevant BCA calculations.
