Abstract:
Addressing sustainability issues in the delivery of an infrastructure project requires, firstly, a definition of sustainability which accounts for the specifics of that project. However, sustainability is such a complex concept that defining it "on the ground" can be problematic. A process for articulating a working definition would be useful for sustainability practitioners to communicate and translate sustainability into meaningful terms for stakeholders in specific projects.

This paper outlines a process for developing a working definition of sustainability for application to the delivery phase of an infrastructure project, and uses the results of a semi-structured interview process with the NSW urban rail sector, including design engineers, planners, consultants and rail authorities; along with a review of infrastructure sustainability literature. The author’s practical experience as a sustainability consultant to large infrastructure project proponents is also drawn on to address the paper’s objectives.

Key findings include that a process should:

  • Include negotiation and collaboration across project stakeholders in early stages of project delivery using a workshop approach.
  • Be driven by a sustainability manager who facilitates stakeholder involvement.
  • Utilise technical expertise within the project team.
  • Identify key sustainability risks and opportunities.
  • Reflect prevailing governance structures and procurement methods.
  • Enable communication in language that project stakeholders will understand.
