Case Study: Inland Rail – Gowrie to Kagaru, Queensland

Inland Rail is a $10 billion investment in moving freight through and inland corridor between Melbourne and Brisbane to avoid metropolitan bottlenecks. The section from Kagaru to Gowrie requires a $5 billion investment for its design and construct elements due to its geographic and technical complexity.

Gowrie – Kagaru rail section in Queensland

Project Value:

> AU $5 billion

Overview of Works:

Inland Rail is 1,700 kilometre rail line between Melbourne in Victoria and Brisbane in Queensland. The 128km Gowrie to Kagaru section of new and upgraded rail track is the most geographically challenging and technically complex of the 13 projects comprising Inland Rail. It requires the construction of a 6.2km tunnel through the Toowoomba Range, numerous viaducts, bridges and crossing loops to build.

The Australian Rail Track Corporation (ARTC) appointed Regionerate Rail – a consortium comprising Plenary Group, Clough, GS Engineering and Construction, Webuild and Service Stream – as preferred bidder for the development of the Gowrie to Kagaru section. The contract is worth more than $5 billion for the design and construct elements.

AES was engaged to work with and across all of the engineering disciplines in whole of life solution development.

Works included:

  • Lead for the asset management team
  • Work with Design SMEs across all asset types – tunnel, bridges, viaducts, MEP, etc, providing design solution input
  • Member of the systems engineering working group performing RAMS analysis
  • Prepare and present at client Interactive Technical Workshop (ITW) sessions
  • Development of asset management framework and delivery solution
  • Prepare various parts of the tender bid submission – asset management and review a number of engineering discipline Returnables

Deliverables / Outcomes:

AES provided a number of outputs including:

  • Development of the Asset Management and Maintenance Services Response Document
  • Development of the Asset Management Plan
  • Input into the Systems Engineering Plan
  • Input into the Digital Engineering Plan
  • Input into the Interface Management Plan
  • Input into the Innovation Plan
  • Review a number of engineering discipline returnables
