Geotechnical Engineer- Takes samples of the soil on your piece of land to give you a classification of the soil type that you are building on. The structural engineer will then use this to calculate the structural components specified in the detailed documentation (slab and footings etc).
Structural Engineer- Specifies in detail all the structural components within the project.
Energy Efficiency Consultant- Assesses the design and the proposed specification of the build to ensure it meets the minimum standards for energy efficiency (all homes must be a minimum of a 6 star rating).
Building Certifier- Whilst engaging a building certifier isn’t a requirement, it is a huge benefit when lodging your documentation to council as it fast tracks the process. A building certifier will assess the plans against the Building Code of Australia, or BCA, to ensure it meets the required standards and will then provide a Certificate of Design compliance (also referred to as a CDC).
By lodging ‘certified’ plans to council it fast tracks this stage, with council processing the application within 10 working days, with reduced council processing fees. However, if you lodge ‘uncertified plans’ to council, they can take up to 25 working days to process and will be subject to the full processing fee.
Building Code of Australia – Also referred as the BCA, is a uniform set of technical provisions for the design and construction of any buildings structures throughout Australia.
Australian Standards – Commonly referred to as AS are documents setting out specifications, procedures, and guidelines. They are designed to ensure products, services and systems are safe, reliable and consistent.
Certificate of Design compliance – Or commonly referred to a CDC, is a certificate provided from the Building Certifier stating the building permit application package is compliant with the required Australian Standards and Building Code of Australia and is therefore ready to be lodged to council as a Certified Building Application.
Larger projects (i.e multi-residential) will require additional consultants. These consultants can include an acoustic engineer, fire engineer, mechanical engineer, hydraulic engineer and civil engineer among various others, depending on the exact nature of the project.
The whole package (detailed drawings including the required information from all of the engaged consultants) along with the Building Certifier certificate of design compliance (if this process is selected) is then lodged to council for a Building Permit under the selected builders builders registration.
Building Permit - Also commonly referred to as a building application, building approval or building license. This is the final approval process from council.
If you are an owner builder, prior to lodging your documentation for building approval, you will need to lodge an application to the Department of Commerce for an owner builder application in order to receive your owner builder license.
Once approval is granted by council for the building permit, your project has received the green light and construction can officially begin!
