What is unsustainable infrastructure?

  • stranded asset
    • financially – poor business case, social liscence, economic changes etc
    • physically – natural hazards (including climate change)
  • negatively impacting the majority to service the minority
  • direct and indirect environmental and social degredation
  • resists, retards and reversees liveable city and community objectives, outcomes and opportunities
  • ignoring system and network optimisation over short term project pipeline priorities; project focussed not solution focussed


  • improved governance

  • social and environmental return
  • advanced benefit cost and associated business cases
