NSW treats excavating as trade work in its own licence category. The NSW Government describes it as removing earth or rock down to a previously decided level or excavation line, to form a hole or trench for structural supports, for building walls or floors, or in preparing for structural landscaping. A contractor licence is needed to carry out, advertise or contract for residential work of this kind valued at more than $5,000 in labour and materials, GST included, and unlicensed work can draw fines of $22,000 for an individual or $110,000 for a company. Accepted qualifications include the RII30820 Certificate III in Civil Construction Plant Operations, and applications start at Service NSW. If you also build retaining walls, driveways or paving, those come under structural landscaping, a separate category; our Sydney landscapers page covers it. A site that lists both should show which categories your licence actually holds.
Spoil is where a Sydney job gets expensive, and the rules are firm. The NSW EPA defines virgin excavated natural material (VENM) as natural material such as clay, gravel, sand, soil or rock fines from ground not contaminated by manufactured chemicals or industrial, commercial, mining or agricultural process residues, and with no sulfidic ores or soils or other waste; the person generating the material has to look at past and present land use on the site and around it before calling it VENM. Under the EPA's illegal dumping laws, the owner, the transporter and whoever receives the waste can all be committing an offence, with on-the-spot fines of $15,000 for individuals and $30,000 for corporations for larger-scale dumping, and maximum penalties doubled when the waste contains asbestos. Disposal space is also getting tighter: the EPA predicts the landfills serving Greater Sydney will be in deficit for construction and demolition waste by about 1.9 million tonnes a year, and expects the cost of managing that waste to rise. A page explaining how you classify and where you take spoil answers a question builders and owners will ask anyway.
Under the ground, Sydney's electricity network is split by area. Ausgrid says NSW law requires anyone planning excavation to get underground cable plans through Before You Dig Australia, that those plans must be no more than 30 days old when digging starts, and that its standard NS156 applies to excavation near its cables, including hazards such as asbestos conduits and organochlorine pesticides; it expects plans within three working days of an enquiry. Sydney's Greater West is on the Endeavour Energy network instead. SafeWork NSW's code of practice for excavation work treats work in or near a trench or shaft deeper than 1.5 metres as high risk construction work that needs a safe work method statement, requires a trench at least 1.5 metres deep to be secured from unauthorised access, and says digging below the footing of a neighbouring structure, retaining walls included, should be assessed and supported by a competent person. On tight inner-suburb blocks with a house each side, a line on how you handle that reassures an owner straight away.
Some earthworks don't need council approval, but only within the State's exempt development standards. NSW Planning lists among them: not working on a heritage item, staying in the rear yard in a heritage conservation area, keeping at least 40 m from a natural waterbody, not redirecting surface or ground water or carrying sediment onto a neighbour's land, and keeping retaining walls at least 2 m apart. Any structure on or over public land or a road needs approval from the council or Transport for NSW. Your website doesn't need to reproduce any of this, but saying that you check the approval pathway, or work from the builder's consent, separates you from a machine-and-a-mobile operator.
Sydney customers search by region and suburb: the Hills District, the North West growth area around Box Hill, Marsden Park and Riverstone, Penrith, Campbelltown, the Sutherland Shire, the Northern Beaches and the Inner West. If you charge a float fee beyond a certain distance from your yard, the service-area section can say where it starts.
