Form 15
Do You Actually Need a Form 15?
A Form 15 is typically required when an engineer must certify that a design complies with Australian Standards and relevant building regulations before construction or certification can proceed.
You may need a Form 15 if:
✔ Structural or civil engineering designs are being submitted for approval
✔ A building certifier has requested engineering certification
✔ Retaining walls, slabs, drainage or structural elements require design sign-off
✔ You are preparing documentation prior to construction
If you’re unsure — that’s completely normal. Many clients contact us simply to confirm whether a Form 15 applies to their project.
