Additional Information & Variation Topic:
If your site has H2 or P soil conditions, additional costs will apply to re-engineer the footings and conduct the installation to variation requirements.
Every site is unique, and no two sites are the same. As a result, we cannot determine the exact requirements of an individual site without conducting the necessary assessments, reports, and surveys. While our standard inclusions aim to cover most situations, if your site requires anything beyond what is included, we will transparently communicate any potential variations before your full commitment.
Potential foundation variances that may arise after a detailed site checks include the following:
Scenario: Your site has volatile soil, and the footings need to be reengineered.
If the site has volatile soil conditions requiring the footings to be reengineered, we will assess the requirements and advise of any factors that arise. This may include adjustments to additional engineering considerations, or modifications to the construction process to ensure stability and compliance. Any necessary changes or outside of allowance costs will be communicated as they are identified. Any such variances found in our site checks will be clearly communicated to ensure transparency.
- Installation is included in our Complete Dwelling, Council and Installation Package. The standard inclusion and allowance for the Complete Dwelling, Council, and Installation Package includes dwelling installation within a 100km radius of a capital city port.

Additional Information & Variation Topics:
Our standard inclusions are designed to accommodate a broad range of scenarios; however, every site is unique, and no two sites are the same.

For those who choose our Complete Dwelling, Council, and Installation Package, for complete transparency, potential variances that may arise after a detailed site survey include the following:
Scenario: Your site is located beyond 100km from a capital city port.
In this case, our team will assess and confirm any additional travel costs that may apply for our builders.
Scenario: Your site has accessibility challenges.
If access to the site is restricted, requiring alternative entry methods, specialised equipment, or manual transportation of materials, may result in increased labour and time requirements.
Any such variances found in our surveys will be clearly communicated to ensure transparency.

Additional Information & Variation Topic:
Clear and level access is defined as being 3.5m wide with a maximum fall of 100mm every 5 metres. This also includes clear access from powerlines along both the roadside and the site. Unloading is considered standard, provided there is clear, level, and direct access to the site.
Potential crane transport variances that may arise after a detailed site checks include the following:
Scenario: Your site has accessibility challenges, and the crane needs to do an altered lift.
If your site has accessibility challenges or requires a larger crane, this will be noted during the site survey inspection. If necessary, Expandify will arrange for a local crane company to visit your site and provide a revised quote for this variation. If the requirements fall outside of the standard inclusions, we will handle the arrangements and inform you of any variation to the standard inclusion.
Any such variances found in our site checks will be clearly communicated to ensure transparency.
