Modular buildings go through the same compliance path as any permanent structure in Australia, assessed against AS and NCC like any other build. The difference is where the certification work actually happens: in the factory, during production, not after the modules land on site. Here is how structural sign-off works on an EcoPrestige project.
What gets certified, and by whom
Each module’s structural design is certified by an Australian engineer, who issues a Regulation 126 Certificate of Compliance confirming the structure meets the relevant Australian Standards and the National Construction Code. This sits alongside an evidence-of-suitability pack, the documented basis a building surveyor relies on to accept a manufactured building element into a building permit.
Where the building surveyor fits in
Rather than inspecting a finished module after it arrives on site, the client’s building surveyor is engaged into an off-site inspection regime during production, reviewing the module at the stages that actually matter, framing, structural connections, services rough-in, before it is closed up and shipped. This is what lets a module arrive on site ready to install rather than needing to be opened up again for inspection.
Why this is faster than inspecting after delivery
A structural element that can only be inspected once it is on site creates a hard stop in the program, work waits for the inspection, and any defect found means remedial work in the field, under weather, with less access. Certifying and inspecting through production instead means the structural compliance question is already closed by the time the crane turns up.
What a builder or developer needs to provide
The client’s own building surveyor stays engaged throughout, this is not EcoPrestige self-certifying in isolation. What changes is when and how that surveyor does their job: reviewing a documented off-site inspection regime and the Regulation 126 certification, rather than only inspecting a finished product on site.
FAQ
Who issues the Regulation 126 certificate?
An Australian structural engineer, confirming the module’s structural design meets the relevant Australian Standards and the National Construction Code.
Does the client’s building surveyor still need to inspect the modules?
Yes. They are engaged into an off-site inspection regime during production, inspecting the module at the stages that matter before it is closed up, rather than only inspecting the finished product on site.
Is this a different compliance pathway to a traditional build?
No, the building is still assessed against AS and NCC like any other permanent structure. What changes is the timing and location of the inspection and certification work.
What happens if an issue is found during production?
It is addressed in the factory, under controlled conditions, before the module ships, rather than becoming a site remedial issue after installation.
Need the compliance basis for a tender or a permit application?
We can provide the Regulation 126 certification approach and evidence-of-suitability pack structure for your building surveyor to review. Email info@ecoprestige.com.au or download our technical brochures.
