Estimates based on supplied values
The calculators produce arithmetic estimates from the values entered. You are responsible for checking measurements, units, product specifications, supplier rates and the scope of the work. Default values illustrate how a tool works and should not be treated as a recommendation for a particular project.
Information and calculations are provided without a guarantee that they cover every installation detail or will match a final supplier order. Availability and operation of the website may change.
Professional and product requirements
These tools do not provide structural design, installation certification, legal advice or a determination of local tax treatment. They do not replace product instructions, project specifications or the judgement of a qualified professional where that is required.
Review final material quantities, allowances and purchase increments with the supplier or installer. Confirm the suitability of any proposed material or design through the appropriate project process.
Quotation documents
You may use the quotation generator to prepare and download your own documents. You are responsible for the accuracy of business details, customer information, descriptions, prices, taxes, terms and commitments included in them.
Generating a document does not send it to a customer, obtain acceptance or guarantee compliance with the document requirements of a particular jurisdiction. Review a quotation before sharing it.
Responsible use and references
Use the website in a way that does not interfere with other visitors or the operation of the service. Do not use the tools to create deceptive documents or misrepresent another person or business.
External references are provided to explain measurement conventions or product assumptions. A reference does not imply endorsement of Build Calculator by the referenced organisation, and its content may change independently.
Your rights and questions
Nothing in these terms is intended to exclude rights that cannot be excluded under applicable law. The contact page provides the available route for questions about the website and its calculations.
