Earthwork carried out within the residential, commercial, and mining sectors needs to dislodge and move large amounts of soil, rock, and other material. Excavation and backfill are the main type of earthwork, but not the only one; other operations include site preparation and cleanup; stripping; driveways and landscape leveling, contouring and shaping; tree and stump clearing; material cutting, spreading, and trimming; creating spoon and table drains dozing; dam construction; land grading for slopes stabilization.
There are companies offering both human and technical resources for hire to assist with projects within specified areas; more precisely, both specialists and entire fleets of dozers and drotts. These fleets are made up of heavy duty machinery, such as bulldozers, trucks, dragline excavators, graders, loaders, etc, built specifically for earthmoving and construction projects.

Different jobs require machines of different sizes and capabilities
Some earthmoving in Brisbane machines are fitted with spreader bars and laser leveling to ensure a perfectly leveled finish, while some are also equipped with reduced ground pressure tracks that enable them to move across soft ground. These larger tracks make extended contact with the ground and thus apply low pressure so that the machine stays stable even on very soft terrain. This ability is further enhanced by the extended undercarriage and the added track roller.
The versatility of the drott (also called a track loader) makes it a popular presence on most construction sites, particularly because when compared to dozers, drotts have a flexible bucket that can be used for many purposes, including bulldozing, loading, and collecting debris. Most widely used drotts are the Caterpillar and the Liebherr brands; for instance, the newer Caterpillar drott models have been redesigned and improved so that operating costs are lower, the operator cab is more comfortable, and the machine has extra horsepower, a hydrostatic drive system, a double grouser track shoe with a standard ground contact area of 2.3 m2, etc.
The ripper-scarifier is a ground-engaging tool mounted on the rear of earthwork machines like the drott; it has three shanks fitted on a hinge and operated by two cylinders that raise and lower the tool to help with the grading process.
When excess water is present on site, an excavator is employed to clear rocks and other obstacles, then special machines can be used to dig drains up to 1.2 meters deep to collect surface water. As with other types of earthwork machines, the drain digger has a laser system onboard which ensures the grade is even; alternatively, a spoon drain bucket also fitted with a laser system can be used; the spoon drain can have a width of up to 2.5 meters.
