Client: Rio Tinto Iron Ore Expansion Projects
Capex: $1.7 Billion USD
Location: Pilbara, Western Australia
Completion Date: 2013-2015

Rio Tinto Iron Ore Expansion Projects engaged Calibre Global as the EPCM for the expansion of their Yandicoogina (Yandi) mine. The phase of the project DBM Vircon was involved with increased production from 53 to 56 million tonnes per annum (Mtpa).
Project Details: The expansion project included construction of a new primary and secondary sizer plant at Junction South West (JSW); modification to existing dry plant at Junction Central (JC); construction of overland conveyor from JSW to JC; construction of a new wet plant at Junction South East (JSE); additional stackers and conveying infrastructure within the stockyard and upgrading to existing site wide infrastructure.

Project Stats:
  • Over 15,000 tonnes issued
  • 28 Conveyors
  • 416 Active models
  • 320 Models issued
  • 68,711 Issued fitting details
  • 77 Areas and 1,101 phases
  • 49,172 Issued detail drawings
