Westforce Constructions delivers bulk earthworks and site preparation for mine-site, energy and civil projects across Western Australia. Part of the Raubex group, with more than 320 people across WA, we self-perform the full scope: site clearing, mass haul and cut-to-fill, excavation and backfill, soil stabilisation, ground improvement and remediation. Earthworks are the first true test of a project. Get the formation right and every scope that follows starts strong, which is why we assess conditions early, lock in access and sequencing before the machines roll, and build formation that is safe, compliant and ready for the trades behind us.
Bulk earthworks: heavy cut, fine trim, and everything in between
Westforce delivers high-volume excavation, cut and fill operations, backfill and subgrade preparation with efficiency. Just as critically, we execute detailed excavation and final trimming with precision. Our teams handle foundation zones, drainage benches and fine-tolerance work using GPS-controlled machinery and tight handover sequencing. That combination of scale and accuracy removes rework, gives clients confidence in what has been built, and lets downstream trades start with certainty.
Mine-site earthworks and non-process infrastructure (NPI)
Much of our earthworks scope is delivered on operating mine sites across the Pilbara, Goldfields and beyond, where the civil works sit outside the processing circuit but keep the site running. This is the non-process infrastructure (NPI) that miners and their EPCM contractors package and tender separately: the bulk earthworks, hardstands, laydowns, roads, stockyards and the foundations and slabs that workshops, warehouses, tanks and facilities are built on.
Westforce has delivered named NPI packages for tier-one resources clients, including the Iron Bridge NPI mobile maintenance works and the Newman ROM 4 NPI SMPEI and concrete works. We self-perform the earthworks and concrete, coordinate the trades around them, and give you one accountable contractor for the civil scope, on a live site, without slowing production down.
Solutions at the point of pressure
Ground conditions don’t always match the drawings. When that happens, we adapt quickly and maintain momentum. Our supervisors stay present and solutions-focused, bringing experience and accountability to every shift.
With a can-do attitude and personal accountability, we find the solution. That might mean stabilising a soft area, adjusting a line to suit conditions, or getting a new spec approved without delay.
Connected across disciplines, consistent in control
Earthworks never operate in isolation. They sit at the junction of civil, structural and services. Westforce makes sure those links are seamless. Engineers, surveyors and client teams are aligned from the outset. Each element of formation is built to serve what comes next.
Operators understand the technical benchmarks. Supervisors monitor quality, pace and safety. Reporting is clear, and no gaps are left between trades.
Confidence at every level
We work shoulder to shoulder with engineers, surveyors and client teams to make sure the earthworks scope is aligned with every other discipline. Our operators know the technical requirements. Our supervisors manage the pace and the risk. And our reporting gives clients confidence that nothing is slipping between the cracks.
Clear, honest communication and practical solutions make us a partner people can rely on. We’re not interested in shortcuts. We’re here to deliver a result that supports the project in full. Every bench, batter and base is delivered with that commitment in mind. That includes the schedule, the quality, and the integrity of the ground itself.
