As part of Pilbara Minerals’ growth in the lithium sector, Westforce is delivering the Midstream Concrete and Detailed Earthworks package for a groundbreaking joint venture between Pilbara Minerals and Calix. Located at the Pilgangoora Lithium Mine near Marble Bar, the project supports the development of an innovative midstream lithium processing plant designed to enhance product value on site.
The package includes over 2,500m³ of in-situ reinforced concrete, along with bulk earthworks and deep excavations across a technically demanding footprint. With structural walls rising up to 3.5m high and a major 550m³ foundation pour completed in a single shift, the works demand precise coordination and sequencing.
Working within the constraints of an active mining environment, Westforce has applied detailed planning, consistent delivery and disciplined execution to maintain program momentum. The concrete forms the structural base for new midstream technology, helping shape the next phase of lithium processing on site.
Westforce is delivering the scope under a Construct Only contract, with a mix of structural concrete, bulk excavation, underground services and HDPE infrastructure. The works are being carried out with a strong focus on structural precision and safety within a live operational zone.
Scope highlights:
All components are staged to integrate smoothly with future equipment installation and commissioning phases.
Concrete Volume: 2,600m³~
Bulk Earthworks: 5,600m³~
Reinforcement Steel: 320T~
