What Is a Form 12 and Why It Matters for Your Project
Understanding Form 12 for Queensland Building Projects
A Form 12 is an essential part of the building process in Queensland and is often required after site inspections or when certifiers need confirmation that work has been completed correctly. For many homeowners and builders, it can be confusing to know when a Form 12 is needed and what it actually certifies.
Here is a simple breakdown from the team at JC Engineers.
What Is a Form 12?
A Form 12 is a Certificate of Inspection that confirms building work has been inspected by a competent person and complies with the approved design, NCC requirements and relevant Australian Standards.
While a Form 15 certifies the design, a Form 12 certifies the actual construction work.
When Do You Need a Form 12?
A Form 12 is commonly required when:
An engineer or competent person inspects structural work
A certifier requests confirmation that the installation is compliant
There have been construction changes that require engineering oversight
You need evidence that works were inspected before concrete is poured or elements are concealed
You will often see Form 12 requests for footing inspections, steel placement, retaining walls, roof structures, framing, alterations, renovations and rectification works.
Why Is a Form 12 Important?
This certificate:
Ensures the builder has followed the approved engineering design
Confirms compliance before work progresses
Helps prevent costly rework, defects or failed council inspections
Provides certifiers with the documentation they need to approve the next stages of construction
A Form 12 protects the client, builder, engineer and certifier by ensuring every step meets compliance.
What Is Included in a Form 12?
A Form 12 issued by JC Engineers includes:
Details of the inspection carried out
Confirmation that the work complies with the approved design
Any conditions or requirements that must be addressed
The engineer or inspector’s credentials
Form 12 vs Form 15: What Is the Difference?
Form 15 confirms the design is compliant.
Form 12 confirms the construction work is compliant.
Both play an important role in delivering safe, compliant and high-quality projects.
