Earthworks involves excavation and grading of the land to prepare it for the installation of civil infrastructure. Excavation includes the removal of any vegetation, trees, rocks, and debris that may hinder the development process. Grading, on the other hand, involves shaping the ground to ensure it is level and has proper drainage, as well as to prepare for the installation of utilities.
Once earthworks are completed, the next step is to install the sewer and drainage infrastructure. This is an important step to ensure the proper disposal of wastewater and the prevention of flooding. This involves excavating trenches for the pipes, laying pipes in the trenches, and then backfilling the trenches with soil. The sewer and drainage systems are also connected to the overall network to allow for the proper disposal of waste and drainage.
Water supply and gas mains are essential for providing potable water and gas to the properties being developed. These mains are typically installed by laying pipes and connecting them to the main water and gas supply.
Once the water and gas mains are installed, the electrical and telecommunication infrastructure, including power and NBN lines, are installed. This involves laying cables and connecting them to the main electrical and telecommunication supply. Installation of streetlights and other essential infrastructure are also be included in this step.
Once the infrastructure is installed, the next step is to construct the roads and kerbs. This involves grading and compacting the ground, laying a base layer of crushed rock, and then adding asphalt to create the road surface.
After the roads are constructed, the next step is to lay concrete footpaths and driveways as well topsoil adjacent the title boundaries and footpaths. This involves pouring and finishing the concrete for the footpaths and driveways, topsoil is spread between the lot and footpath in preparation for the streetscaping works.
