The project was developed for a Phase 1 capacity of 45 Mtpa including mine site ore handling infrastructure, marine facilities to enable the export of 45 Mtpa of iron ore through Port Hedland, rail and port materials handling facilities at Anderson Point and Harriet Point, and 256 km of heavy haul rail connection.
WorleyParsons provided technical solutions to a wide range of geotechnical challenges including:
- Geological mapping of 256 km rail corridor, 50 km mapping via helicopter
- Investigation program comprising 1,440 m borehole drilling and 1,350 test pits
- Laboratory test program comprising 2,000+ samples
- Design of 82 km of cuttings based on geological models developed
- Geotechnical slope stability assessment for 256 km of railway embankment
- Sourcing of 6 million m3 of borrow for rail construction
- Developing geotechnical design solutions for the management of soft soils around the port and collapsible soils along the rail formation
- Design of 22 m deep 150,000 m3 excavation for train unloading facility
- 3D FEM design of roof vaults supporting 45 m high iron ore stacks
- 5 million m3 dredging and land reclamation program
- Foundation design for 13 communications towers of 65 m height
- 670 m of driven piles for port facilities
Completed in three years, this was the fastest ever delivery of a mine-to-market project.
