Modular Certification

Getting a factory-built home approved

A modular home has to satisfy the same National Construction Code as any other house. What differs is where the evidence comes from. Much of the structure is enclosed and lined before it ever reaches the site, so the inspection regime that works for a conventional build — turn up when the frame is exposed — has to be rethought.

That makes documentation the backbone of a modular approval. Certifiers and councils are being asked to accept a structure they cannot fully see, and the paperwork has to carry that weight.

How structural engineers help

We provide the detailed drawings and calculations required for building approvals, and compliance certification for the structural design — in Queensland, the Form 15 Compliance Certificate for Building Design or Specification that your certifier will ask for.

Where structural elements are inspected during manufacture rather than on site, we attend at the stages that matter and issue the corresponding inspection documentation, including Form 16 where it applies. Our team conducts inspections to ensure that work is being carried out according to the required design specifications, and we can adjust our plans in response to site conditions or unforeseen challenges.

For homes crossing the border into Northern NSW, the approval pathway is different and the certification is prepared to suit the New South Wales process rather than the Queensland one.

What you receive

Structural drawings and calculations, compliance certification for the structural design, inspection attendance and inspection certificates at the agreed hold points, and the documentation package your certifier and council need to approve the home.
