Create a credible route

The challenges shaping infrastructure delivery include increasing project complexity and cost pressures, energy systems needing to adapt to pace of global decarbonisation, and increasing engineering, environmental & societal constraints on route options. Tourmaline provides solutions to these challenges through:

  • An automated approach

    Tourmaline enables clients to identify constraints and credible route options faster, reducing time and effort at the earliest stage.

  • Rapid comparison of route corridor options

    Tourmaline helps identify the most consentable option as constraints or assumptions change.

  • Building the route narrative

    Tourmaline creates a transparent, defensible evidence base for route decisions, supporting greater confidence in consentability.

Construct the route narrative
