Terrain Modification

Gajawari KW provides full-scope terrain modification services, covering bulk, civil, and detailed earthworks along with excavation and trenching for utilities and structural elements. Works include cut-and-fill operations, pad shaping, trench formation, and site grading to meet design tolerances and geotechnical requirements. Executed with precision equipment and strict QA controls, these services support efficient ground preparation for infrastructure, mining, and industrial developments across WA.

Groundworks are planned to protect heritage sites, with excavation and trenching locations verified against cultural registers through early assessments and consultation with Traditional Owners.

Bulk Earthworks

We deliver large-scale earthworks involving mass cut, fill, and compaction across civil, mining, and infrastructure projects. Works are executed to spec with control over geometry, sequencing, and site conditions.

Civil Earthworks

We perform precision earthworks to support infrastructure, site prep, and resource development. Works are staged and controlled to meet design tolerances from bulk reduction through to final trim.

Detailed Earthworks

We deliver fine-tolerance earthworks for structural zones, service areas, and final surface prep. Works involve close control over shaping, trimming, and compaction to meet design-specific margins.

Excavation & Trenching

We undertake excavation and trenching for utilities, drainage, and foundations with precise line and level control. Works are staged to maintain access and minimise disruption in active environments.
