Australia’s 560 Councils are responsible for the management of a range of assets valued at approximately $212 billion, many of which have a life span greater than 50 years and so will be affected by climate change. 

Currently, maintenance and replacement of hard infrastructure by Local Government is guided by the principles, models and tools provided in the International Infrastructure Management Manual (IIMM), developed by the Institute of Public Works and Engineering Australia (IPWEA) in conjunction with Councils, engineers and manufacturers of various components and materials. Currently these tools do not allow for the incorporation of climate change impacts or calculate the likely flow-on effects to asset and financial management and so Councils are limited in their capacity to estimate these changes.

This document is an Addendum to the National Climate Change Adaptation Research Facility (NCCARF) Settlements and Infrastructure funded research project to develop a financial simulation model and supporting decision tools to provide a clear, comparative analysis of the financial impacts of climate change on three major asset classes of importance to Australian Local Government – sealed roads (hotmix and spray sealed) and unsealed roads. The full report of the original project is available from the NCCARF Website at: http://www.nccarf.edu.au/publications/quantifying-cost-climate-change-impacts 

This Addendum provides contextual information to the original full report and details on the expansion of the financial model and supporting decision support tools in collaboration with IPWEA to include additional climate data sets for a total of 75 local government areas across southern Australia. In addition, three workshops across southern Australia in Perth, Adelaide and Melbourne were run to extend the findings of the original project and this additional work to local government engineers, asset managers and financial managers.

The expanded model will provide Local Government with the capacity to update road asset maintenance and replacement cost analyses to include climate change. The outputs have been designed to interface with the existing tools developed to support the IIMM or other Excel based asset management tools and include a simple user friendly look up table that can be used by Local Government staff.
