Tasmanian trailblazers

Our DM Roads team working on the North West Tasmania Road Maintenance contract are ticking off a number of firsts in the State.


Working in partnership with the Department of State Growth Tasmania, they’re not only maintaining roads, they’re also blazing a trail for sustainable solutions in Tasmania. 

It’s the first road contract in Tasmania to lay a bitumen sprayed seal modified with crumbed rubber sourced from waste tyres, first to use battery-powered equipment to reduce noise and greenhouse gas (GHG) emissions, and first to obtain ISO 55001 Asset Management accreditation.

These solutions are improving the durability of Tasmanian roads and providing better experiences for the local community and road users. The initiatives have also led to another major first for a Tasmanian road project – an Infrastructure Sustainability (IS) Operations rating from the Infrastructure Sustainability Council of Australia (ISCA).

The IS rating scheme provides a framework around sustainability, and fosters a culture of efficiency and waste reduction. 

Obtaining this IS rating achieves a key goal set by Downer in our 2019 Sustainability Report. It also demonstrates the economic, social and environmental benefits of the approach taken by DM Roads in partnership with our customers to deliver services that create shared value through employment opportunities for disadvantaged Australians and support the North West Tasmanian community.

Setting the standard in sustainability

DM Roads, our customer and supply partners are implementing a range of initiatives on the North West Tasmania Road Maintenance contract. 

  • First contract in Tasmania to utilise battery-powered chainsaws, resulting in a 19 per cent reduction in noise, significant reduction in GHG emissions,
    and significant cost saving
  • First contract in Tasmania to utilise crumbed rubber, removing 668 tyres from waste piles and resulting in a five per cent reduction in GHG emissions or 880kg CO2-e
  • Delivered ISO 55001 asset management accreditation, which improves decision making using real time, specific and accurate data; reduces unnecessary maintenance; and implements whole-of-asset lifecycle considerations
  • Community-focused delivery model has created 33 full-time local jobs, including 28 people from disadvantaged backgrounds.

This project demonstrates Downer’s contribution to achieve the following Sustainable Development Goals:
