The earthworks involve all the bulk cut and fill works to bring the stage to the designed finished surface level.

The sewer works are the first item completed after Earthworks as it is typically the deepest service. This involves the construction of the sewer pipelines, the authorities maintenance structures and individual lot connections.

The drainage typically follows sewer and involves the construction of the drainage pipes and pits to ensure the stage will drain efficiently.

Water and gas usually share a trench due to their close proximity and are constructed at a similar time. The construction involves the installation of pipework, valves, hydrants and individual lot connections.

Subgrade is considered the road base and is critical to the future performance of the road. It is made up of the subgrade (natural clay or engineered fill), capping layers and crushed rock layers.

The kerb and channel is the concrete edging of the asphalt designed to catch stormwater flow and direct it into the drainage system.

The electrical and NBN services are the last services to be constructed as they are typically the shallowest. This involves the construction of the “pit and pipe” for each service.

This is the final clean up portion of the works with all the finish touches constructed and installed. During this phase of works you will see concreters constructing footpaths, asphalt crews layer the base, intermediate and wearing course asphalt and bobcats spreading top soiling across lots and nature strips.

This indicates that construction is now complete and that Statement of Compliance (SOC) is now underway. See the SOC process below.
