Structural steel recertification: when you need it and how it works

6 min read

Mezzanines without paperwork, change of use, added load or damage. What happens between the first inspection and the signed certificate.

Recertification means getting a structural engineer to confirm that an existing steel structure is fit for the way it is being used today. It usually comes up when someone asks for paperwork that nobody can find.

When it comes up

  • A certifier, council or insurer asks for certification of an existing mezzanine, platform or canopy.
  • The use of a space changes, for example storage racking moving onto a mezzanine built for foot traffic.
  • New load is being added, such as plant on a roof frame or a heavier floor finish.
  • A member has been hit, cut, corroded or modified without sign-off.
  • A property is being sold or leased and the due diligence flags the structure.

How the process runs

  1. Site inspection. We measure members, connections, bolts and welds, and record their condition with photos.
  2. Engineering review. A qualified structural engineer checks the structure against the intended loads and current Australian Standards.
  3. Outcome. The structure is certified as is, certified subject to modifications, or found unsuitable for the intended use.
  4. Modifications. Where needed, we carry out the work the engineer specifies: stiffeners, extra bracing, new bolts, plates or members.
  5. Sign-off. The engineer inspects the completed work and issues the certificate.

What speeds it up

Any original drawings, previous certificates, photos from construction or the name of the original builder all help. Clear access to the connections helps too, since hidden details often need to be exposed for inspection.

We coordinate the engineer, the inspection and any modifications so you deal with one contact from the first visit to the final certificate.
