What exactly are bulk earthworks?
Bulk earthworks include the removal, moving or adding of large quantities of soil or rock from a particular area to another. They are carried out in order to make an area a suitable height and level for the construction of a building. The way they are carried out are by cutting into, or excavating, an area of ground or by constructing a new area.
When bulk earthworks are taking place, the aim is to reuse as much as possible of the excavated materials to prevent both the costly collection of waste material and the delivery of extra earth materials. This is done by using specialised computer software which can calculate both the amount of material that will be removed and what will be needed to complete the job. Surveyors and engineers aim to match the soil volumes being used for both processes.
What types of excavations are used during bulk earthworks?
Excavation can be classified in two ways. Firstly, by the type of material that is being excavated and secondly by the purpose of the excavation. When classification is based upon material type, it is very important that the material is accurately identified to keep costs down and prevent technical problems occurring. Surveyors and engineers use various methods to measure how easy or hard the earth is to dig.
Four general categories are:
EASY – loose, free flowing soil or sand
MEDIUM – gravel with clay
MEDIUM to HARD – wet heavy clay, broken rock, gravel with boulders
HARD – materials requiring blasting
Other material-based classifications include topsoil, rock, earth, muck and unclassified (a mixture of earth materials) excavations.
Bulk earthworks are also classified according to purpose. Examples include roadway, bridge, structure, footing, borrow, dredge, channel and drainage excavations.
What types of equipment are used?
Heavy construction equipment is required due to the large quantities of material that needs to be shifted. Examples of equipment that is used includes:
Graders | Rollers | Dump Trucks | Bulldozers | Excavators | Shovels | Diggers | Back Hoes | Loaders
Why choose DIG IT for your next excavation project?
It is important that with any type of earthworks, you choose a company that is reputable and has the specialist experience and knowledge required for the job.
Here at DIG IT, we have a qualified and experienced team that can manage every aspect of the excavation process, including clearing land, excavating rock and managing bulk earthworks and landfill in preparation for construction. We offer bulk excavation services that involve removing, moving or adding large quantities of soil or rock from a particular location to another. We also manage detailed excavations such as building foundations and footings.
We specialise in excavation sites with limited access or tight surrounds and all our machinery is compact with zero swing meaning that none of our machines have a large counterweight overhanging at the rear, so they can fit in tight, confined spaces.
Our work encompasses sites, both residential and commercial, throughout the Greater Sydney area and Central Coast regions and can quote on bulk and detailed excavations based on a cubic metre rate, per tonne rate, or as a lump sum price so you are aware of all the costs up front and can stay within your budget.
