Now, let’s get straight to it! There are three main aspects of Site Preparation that need to be taken care of in order to ensure a stable foundation for your new home.

Here’s what you need to know about the three aspects:

Soil Classification

For this aspect, you will need a geotechnical engineer to analyze the soil at your property. After analyzing a sample of the ground, a specialist will be able to tell you what kind of foundation you need for the house (slab or stump), the suggested depth of foundation as well as outlining potential issues that you might encounter in coming years such as underground waters.
After you get a complete analysis of the soil you can start the site works. The site works usually include:

  • Site scrape – removing the organic matter from the land
  • Removal of the surplus soil
  • Compacting the soil – preparation of the sand pad. Usually, the depth of the sand is given by the geotechnical expert and depends on the site.


Site Survey
Surveying the land on which you will build the house is crucial. This investigation is carried out by a land surveyor that will ensure the property borders are accurate. The land surveyors use purpose-built that measures the vertical and horizontal plans to a high degree of accuracy in order to establish the boundaries of your property so there are not questions when it comes to building regulations or insurance.

Site Inspection
When constructing a new home, there are inspections carried out at different stages of construction to ensure compliance with the Building Code of Australia and other local regulations that may be in place.
These inspections are carried out by building inspectors that are independent to the builders in order to avoid any conflict of interest. Inspections that may be required on your property (depending on specific location) include: 

  • Footing inspection: This is the inspection of excavation and reinforcements prior to placing the house’s footings.
  • Slab inspection: Usually including floor level checks and termite treatment. This inspection is conducted before the foundation is poured.
  • Framing inspection: After the foundation is poured, a specialist will determine if the dimensions and placements of the frame conform to the plans.
  • Waterproofing and plumbing inspection: This is a very important inspection. The specialist will check out if there’s any risk of water infiltration in the new home and if the pipes and plumbing were completed correctly.
  • Final inspection: Conclusive review of all previous inspections to ensure the structure is safe.
