Bulk Earthworks & Earthmoving

Bulk Earthworks & Earthmoving — Western Australia

DCG delivers bulk earthworks and earthmoving across civil and mining projects throughout WA — cut and fill, site clearing, embankment construction, compaction, and spoil management. Supplied with our own plant and experienced operators, or as a full scope delivery package.

Bulk Earthworks — Our Scope

Our bulk earthworks capability covers the full range of civil and mining earthmoving works — from initial site clearing and topsoil stripping through to cut and fill, embankment construction, compaction, and final grading. We bring our own GPS-equipped plant and experienced operators, and we coordinate specialist subcontractors where required for soil stabilisation and related works.

Site Clearing & Grubbing

Vegetation clearing, tree removal, and grubbing across project sites of all sizes — minimising disturbance and preparing the ground for earthworks commencement.

Topsoil Stripping & Management

Careful topsoil removal and stockpiling for later reinstatement — preserving environmental integrity and supporting rehabilitation requirements on civil and mining projects.

Cut and Fill Operations

Bulk material movement to achieve design levels — balancing cut and fill volumes efficiently to minimise haulage costs and keep the earthworks programme on track.

Embankment Construction

Embankment formation for roads, platforms, and civil infrastructure — placed and compacted in layers to specification and design requirements.

Compaction

Soil compaction to specified density requirements using our roller fleet — tested and verified through inspection hold points and soil testing throughout the works.

Erosion Control

Erosion control works self-performed by DCG personnel — sediment barriers, diversion banks, and surface protection measures to manage stormwater and protect disturbed areas during and after earthworks.

Soil Stabilisation

Enhancing soil strength with lime or cement treatments.

Grading & Levelling

Bulk grading and levelling using GPS-equipped dozers and graders — achieving design levels efficiently across large earthworks footprints ahead of pavement or slab construction.

Spoil Management & Material Hauling

Efficient handling, transport, and disposal of excess cut material — coordinated to minimise double-handling and keep the site clean and programme on track.

GPS-equipped earthworks fleet — owned, maintained, and ready to mobilise

Every piece of DCG’s earthworks fleet is owned, mine-spec maintained, and available for rapid mobilisation across WA within two weeks of contract. Our excavators carry Trimble GPS for precision digging and grading — the same technology our grader fleet runs for final trim work.

Excavators — CAT 15T to 40T
CAT excavators from 15-tonne to 40-tonne, Trimble GPS equipped. Suited to bulk dig, embankment work, drainage excavation, and detailed civil works across civil and mining project environments.

Dozers — D5 to D9
Dozer fleet from D5 to D9 — available with or without GPS. Suited to bulk pushing, clearing, and grading operations across civil construction and mine site earthworks.

Supporting Plant
Graders, rollers, watercarts, skid steers, and supporting civil plant available alongside the earthworks fleet — deployed as a package or individually to suit your project requirements.
Need Moxy dump trucks or additional earthmoving plant? We coordinate hired-in plant alongside our own fleet where project scope requires it — giving you a single point of contact for the full earthworks package.

Soil stabilisation — coordinated through trusted suppliers

Where projects require lime or cement soil stabilisation, DCG coordinates this through established specialist suppliers — managing the scope as part of the broader earthworks package. You deal with DCG as a single point of contact while we manage the stabilisation subcontractor, quality testing, and programme coordination on your behalf.

Building toward head contractor bulk earthworks delivery

Dunamis currently delivers bulk earthworks in a support and supply model — providing GPS-equipped plant, operators, and supervisors to Principal clients and Tier 1–3 contractors across WA. Our bulk earthworks capability has been demonstrated across major civil and mining projects including 152km of haul road construction in the Pilbara for Onslow Iron.

We’re actively growing toward taking on broader bulk earthworks packages as head contractor — bringing the plant, people, systems, and project management to own a defined earthworks scope end to end.

If you have a bulk earthworks scope coming up — whether it suits our current support model or represents an opportunity to work with us in a head contractor capacity — we’d welcome the conversation.
