Earthworks

From bulk earthworks to complex land development, we own the massive fleet and GPS technology to deliver millimetre precision on any scale.,

Experts in earthworks

We provide a vertically integrated solution, managing every phase from initial site clearance and cut-to-fill to final engineered compaction. We own the plant, the transport, and the quarries to control the critical path.

Bulk earthworks & site clearing

We handle large-scale excavation and material movement for major infrastructure and commercial projects. Our capacity is proven on projects moving over 1.3 million cubic metres of earth, utilising heavy-duty plant including 49T excavators and motor scrapers to reshape rugged terrain efficiently.

Land development & subdivisions

We transform greenfield sites into fully serviced residential and commercial precincts. Using Leica GPS machine control, we deliver millimetre-accurate trimming for building platforms and roading subgrades, eliminating over-excavation and ensuring seamless integration with three-waters infrastructure.

Complex & technical excavation

We specialise in high-risk environments, from steep-slope wind farm access tracks to excavating contaminated sites. Our team is experienced in deep basement excavations, pre-load construction for aviation facilities, and managing high groundwater tables with engineered dewatering solutions.
