FAQs
You will be charged a design fee upon lodging your application.
Once your project proceeds to construction phase the design fee, excluding GST, is deducted from the price on your Access Offer and Acceptance.
Sometimes your circumstances change and you may need to cancel or change the information within your application after you have submitted it to us.
If you wish to change the scope of work in your application we will first review the change and then either:
- continue the project with the variation and invoice you for any additional materials, design work and remobilisation costs incurred. We will typically only take this approach when the change is very minor.
or
- if the change is significant we will cancel your project. You will need to submit a new application with your new requirements.
For cancelled applications we will invoice you for the costs incurred up to the point of cancellation (time and materials). If construction work has already commenced we will refund the difference from your access offer less any costs incurred.
