National Structural Steelwork Compliance Scheme

Ensuring compliance to minimise risk


The ASI National Structural Steelwork Compliance Scheme (NSSCS) is an independent third party quality compliance and certification system for supply, fabrication and erection of structural steelwork in Australia. The technical basis for the NSSCS is founded on AS/NZS 5131 Structural steelwork – Fabrication and erection and is applicable to structures designed to AS 4100 (structural steelwork), AS 5100.6 (bridges) and supporting Australian Standards including those for welding, bolting and corrosion protection.


Using the newly published steel fabrication Standard AS/NZS 5131 Structural steelwork – Fabrication and erection as the technical foundation, the Australian Steel Institute has developed the National Structural Steelwork Compliance Scheme (NSSCS), comprising four supporting pillars:

  • AS/NZS 5131 as the technical foundation
  • Risk assessment and engineer selection of the Construction Category for the particular project
  • Conformity assessment to the requirements of AS/NZS 5131
  • Auditing and certification of fabricators to one of the Construction Categories through the separate body, Steelwork Compliance Australia (SCA)

4 pillarsHow does the Scheme fit into your project process?

For engineers:

  • Engineer designs the structure and creates the specification using the NSSS as template
  • Specification calls up AS/NZS 5131, Construction Category and project-specific selections
  • More information

For fabricators and erectors:

  • Undertake a web-based audit with Steelwork Compliance Australia (SCA) to establish current level of conformity
  • If needed, work with ASI and accredited trainers to fill any gaps
  • Obtain SCA certification via an audit
  • Maintain certification with annual audits
  • More information

SCA Logo (Primary)For builders:

  • Client/builder selects fabricator, who works to requirements in AS/NZS 5131
  • Best outcomes with a fabricator independently certified by Steelwork Compliance Australia (SCA) under the NSSCS
