A Form 11 Certificate of Compliance (Design) is a prescribed Victorian building form in which a suitably qualified practitioner — often a structural engineer — certifies that a design they prepared complies with the relevant requirements. Building surveyors commonly request one to accompany engineering computations for a building permit.
If your surveyor has asked for "a Form 11 from your engineer," here's what that means.
What is a Form 11?
Victoria's building regulations set out a series of numbered forms used at different points in the permit process. Form 11 is the certificate of compliance for design — the mechanism by which the person responsible for a design formally certifies it.
For structural work, that means the engineer who prepared the structural design certifies that design, alongside the drawings and computations they've provided. It's a statement of professional responsibility, not a formality: the engineer is putting their name and registration to the design.
When is it required?
The most common trigger is straightforward: where a design relies on engineering computations rather than the prescriptive provisions.
Many elements of a standard home are covered by Australian Standards and deemed-to-satisfy provisions that a building surveyor can assess directly. But where an element falls outside those — a long-span beam, an unusual footing arrangement, a structure with non-standard loading — the surveyor needs an engineer's design, and a certificate confirming that design complies.
Council building permit checklists frequently list it explicitly: engineering computations, accompanied by a certificate of compliance from the engineer.
Requirements can vary between surveyors, councils and project types, so your building surveyor is the one who confirms exactly what's needed for your permit.
Who can issue it?
The certificate must come from a practitioner qualified and registered in the relevant category for that design — for structural design, an appropriately registered engineer. This is one practical reason to check registration before you engage anyone: an engineer who can't provide the certification your surveyor requires leaves you stuck at permit stage.
What it isn't
A few clarifications, because these forms get confused:
- It's not the building permit. The building surveyor issues that; the Form 11 is one input.
- It's not a certificate that the work was built correctly. It certifies the design. Certification of completed work is a separate step.
- It's not a substitute for drawings and computations. It accompanies them.
How it fits into your permit
In practice, the sequence usually looks like this: your engineer prepares the structural design, produces the drawings and computations, and provides the certificate of compliance for that design. Those documents go to your building surveyor as part of the permit application. The surveyor assesses the whole package and issues the building permit.

Frequently asked questions
What is a Form 11 in Victorian building? A prescribed certificate of compliance for design, in which a qualified practitioner certifies that a design they prepared complies with the relevant requirements. Structural engineers commonly provide one with their computations.
When do I need a Form 11 from my engineer? Typically when your design relies on engineering computations rather than prescriptive provisions, and your building surveyor requests certification for that design.
Who can issue a certificate of compliance for structural design? A practitioner registered in the relevant category — for structural design, an appropriately registered engineer.
Is a Form 11 the same as a building permit? No. The building surveyor issues the building permit; the certificate of compliance is one of the documents supporting the application.
Does it certify that the building was built correctly? No — it certifies the design. Certification relating to completed work is a separate step in the process.
