Have you been forced to consider alternatives to timber as a result of recent supply chain issues? It’s essential you understand that materials differ widely in their maximum allowable span or loading.
This resource explains what you need to do when the materials you plan to use aren’t available or when alterations occur on-site. It’s always best practice to consult with the building certifier/surveyor to check if proposed changes trigger an amendment to the approval. If so, you’ll need to gather additional evidence, which may require an engineer’s report or a resubmission of the compliance information.
In this detailed resource we cover what's needed to achieve compliance, including use of the housing provisions within the National Construction Code (NCC). If modifications fall outside of the timber framing code requirements, or if a different material is used, an engineer’s assessment may be required. Also outlined are the documents that can be used to demonstrate that the material, product or design meet the NCC.
Read more to ensure you don’t breach building code compliance stipulations when you decide to make project alterations.
