While construction projects vary in size and complexity, they almost always include the same essential steps including laying a solid foundation. ‘Earthwork’ is a term that comes up often in construction and civil engineering, where it plays a crucial role. So what is earthwork in construction? Are kerbs a part of earthworks or do they come later in the process? And why is earthwork so necessary for a construction build?
Pinnacle Earthworks is a locally owned family business servicing Adelaide, Adelaide Hills and all the way out to Murray Bridge. We can take the mystery out of earthwork and its role in the construction process as we provide you with earthmoving and excavation services suited to local conditions. If you’re wondering ‘what is earthwork in construction?’, here is the Pinnacle Earthworks guide.
What is earthwork in construction?
In the fields of construction and civil engineering, earthwork is the process of moving, shaping and processing materials such as soil and rock to make way for buildings, roads, bridges and other developments. It involves excavating parts of the soil as well as refilling and compacting other areas of it, providing a stable foundation for projects. As one of the earliest stages of the construction process, earthwork uses the power of heavy machinery to reinforce a structure’s strength.
Activities
Soil testing
Knowing the variety and chemistry of the soil is an essential first step in any earthworks project. Testing for stability and moisture determines whether it’s safe to proceed with the construction project to begin with or if you may need to relocate to a more stable area.
Stripping and clearing
This stage of the process involves moving trees, plants, topsoil and other debris from the area.
Excavation
Excavation involves using machinery such as bulldozers and excavators to dig out sections of earth and lower the ground level. This is often the first step to laying a stable foundation or installing underground infrastructure.
Filling
This moves soil into lower sections in order to raise the ground level.
Grading and levelling
Grading compacts the earth to create a hard, smooth surface layer and levelling fills dips in the ground and smooths out bumps.
Testing
Testing ensures earthwork is completed to the required design and safety standards and a project is ready to commence.
Equipment
What is earthwork in construction’s most utilised forms of equipment? Machines such as excavators, bulldozers, backhoes, compactors and rollers all have a part to play in effectively moving and compacting the soil.
The importance of earthwork in construction
What is earthwork in construction’s significance? Earthwork is an important part of any construction project for the following reasons:
Stability
Earthwork creates a stable base for any construction project and minimises the risk of foundation issues.
Effective drainage and flood prevention
Earthwork ensures adequate drainage, which helps prevent future structural issues and minimises the risk of flooding.
Higher safety standards
By removing hazards and obstructions in the soil, earthwork makes construction sites safer for workers and anyone else who wanders into the area.
Are kerbs a part of earthworks?
A kerb is the raised edge that separates a pavement or footpath from a road. If you’re managing a civil project or pricing a tender you may be wondering ‘are kerbs a part of earthworks?’
The answer is no. Although both processes happen on a construction site and rely strongly on one another, they remain two distinct phases. The earthwork phase includes bulk excavation and grading, cutting and filling the land. The civil and concrete phase includes pouring or laying the concrete kerbs and constructing channels and gutters to go with them.
Project managers should keep these two scopes independent of one another. Earthworks need to be tested, verified and signed off on before the team responsible for the kerb commences work.
