Mesa A Railway Project

Rio Tinto

Pilbara Region, Western Australia, Australia

The Mesa A Rail Project forms part of Rio Tinto’s Pilbara Iron Railways Division (PIRD) Railway Network and involved the construction of a 47km railway, extending the existing Robe River Deepdale Railway to the recently constructed Mesa A Mine. The completed railway enabled an additional 25Mtpa of iron ore to be transported from the mine to Cape Lambert Port. 

Our team undertook a broad scope of works, which included:

  • 47km of new railway
  • Car dumper track extension
  • New passing station
  • Gas pipeline crossing
  • Fully active and minor road level crossings
  • A rail over road underpass
  • New 280m rail bridge
  • Integrated Control Signalling System (ICSS)
  • Asset protection and required communications
  • Direct locomotive control at the mine, and
  • Realignment of a pubic road. 

The project also involved development of a 760-person temporary construction camp and associated facilities required to support the infrastructure and mine construction activities.

Across the scope of works our team provided all project management, engineering design, cost management, contracts and procurement, construction and commissioning management aspects, from concept through to handover to the client.

The project commenced in early 2005, and was handed over to Rio Tinto Operations on 31 March 2010. The project was completed on time and within budget, with an exemplary safety record.
