RPEQ design certification and drawing stamping explained
In Queensland, engineering services must be provided by or under the direct supervision of a Registered Professional Engineer of Queensland (RPEQ). That signature — the stamp on your drawings — is what a building certifier relies on.
What certification actually means
An RPEQ stamp is a statement that the engineering work complies with the NCC and the relevant Australian Standards, and that the engineer takes professional responsibility for it. It is not a formality and it cannot be applied to work the engineer has not checked.
When you will be asked for it
Building approval through a private certifier or council, retaining walls above the exempt height, removing or altering structure, sheds, decks and pools, form 15 and form 16 documentation, and manufacturer or fabricator drawings that need independent verification.
Certifying someone else's drawings
We can review and certify third-party or supplier drawings, but only after checking the design ourselves: loads, spans, connections, footings and compliance. If the design does not work, we tell you what to change rather than stamp it.
Practically that means a design review fee rather than a rubber stamp. Send the drawings and we quote the review free of charge.
What you get
Certified structural drawings and calculations, form 15 or form 16 where applicable, and responses to certifier and council RFIs at no extra charge on projects we design.
Frequently asked questions
- Can you just stamp my drawings?
- We can certify drawings after reviewing the design. No engineer can lawfully certify work they have not checked, so the review is part of the service — and the quote for it is free.
- Do you provide form 15 and form 16?
- Yes, for structural design and inspection work carried out under our RPEQ registration.
