  • 1. COSTING AUSTRALIAN PASSENGER RAIL PROJECTS 2000-2012: HOW MUCH DID WE PAY AND WHAT DID WE GET? Scott Martin, CMILT University of MelbourneSUMMARYBetween 2000-2012, 28 major urban passenger rail projects were constructed in Australia, at a costof approximately A$8.8 billion. The projects represented in this paper includes heavy rail and lightrail projects constructed in Australian capital cities between 2000 and 2012 involving theconstruction of new rail lines and extension, amplification and electrification of existing rail lines.The data collected in the survey has been scaled up to constant 2012 dollars and further analysed todevelop indicative construction cost profiles for certain kinds of rail projects, along with adiscussion of the various risks and circumstances associated with the inception, development anddelivery of these projects.This is the only known Australian survey examining the finished costs of urban rail infrastructureprojects and represents an important piece of research into the costs of public transportinfrastructure provision in Australia.INTRODUCTION This study attempts to rank the 28 identified urban rail projects by total project cost and cost perIn the years between 2000 and 2012, 28 major kilometre to develop indicative costings for lighturban rail projects were completed in Australia. and heavy rail projects.

Costings methodologyAs these projects were completed across a 12-year time period from 2000 to 2012, a method wassought to approximate each project’s publiclyknown cost at the time of completion into constant(2012) dollars. Data on total costs across therange of projects was obtained using ‘open source’(that is, publicly available) data, as found in annualreports, budget papers, media releases,newspaper articles and the transport trade press.Once a basic cost profile for all projects wasdeveloped, there was a need to equalise allprojects across the 12-year time horizon of thestudy from dollars of the day into constant dollars.Two methodologies for doing this were examined.The first method developed a simple set ofcalculations where ‘as built’ project costs in dollarsof the day were escalated into constant (2012) Figure 2 : Percentage of completed Australiandollars utilising the Australian Bureau of Statistics metropolitan rail projects 2000-2012 by state(ABS) Consumer Price Index (CPI) figures (22).
