Quick Answer
For most residential earthworks, a 1.7T or 3.5T mini excavator combined with a tipper truck covers the majority of applications — site preparation, cut and fill, service installation.
Residential earthworks in NSW typically involve site preparation (stripping topsoil, establishing levels), cut and fill (moving material from high areas to low areas), service installation (trenching for water, sewer, stormwater, electrical), and retaining wall construction. For most residential earthworks projects, a 1.7T or 3.5T excavator combined with a tipper truck is sufficient. The excavator does the digging and loading; the tipper truck removes excess material from site. For smaller residential projects — landscaping, pool construction, service trenching — the 1T or 1.7T is the standard choice. For larger projects — site preparation for new homes, subdivision earthworks — the 3.5T or 5.5T is more efficient. BuildHire can supply multiple machines for larger projects. All earthworks in NSW must comply with the Environmental Planning and Assessment Act and local council requirements. Erosion and sediment control measures are required on all earthworks sites.
For earthworks exceeding 1 metre cut or fill, or affecting more than 100m² of land, development consent is typically required. Check with your local council.
Cut and fill involves excavating (cutting) material from high areas of a site and using it to fill low areas, minimising the amount of material that needs to be removed from or brought to the site.
