Cm3 prequalification for subcontractors: what you need

If a builder, council or facility owner has asked you to “get Cm3”, they want you to complete a contractor prequalification on the Cm3 platform before you work for them. Here's what that means for a concrete, civil or earthworks business, and how to get through it without weeks of back and forth.

What Cm3 prequalification is

Cm3 is an Australian contractor management platform. Clients invite their contractors to join and complete a prequalification assessment based on their type of work and its risks. Cm3's assessors review your answers and evidence and check whether you've assessed the risks of your work, hold the right competencies, and use tools, plant and equipment that are fit for purpose. Depending on the client, assessments can also cover environment, Chain of Responsibility for heavy vehicles, and ethical sourcing or modern slavery.

Evidence that helps you pass

  • A documented WHS management system and safety policy
  • SWMS and risk assessments for the work you'll actually do for that client
  • Certificates of currency for your insurances
  • Licences, tickets and training records for your workers
  • Plant inspection and maintenance records
  • Incident reporting and corrective action records

Cm3 says it doesn't push clients or contractors into a predetermined management system, so your documents don't need to match a template. They need to be real, current and consistent with how you work.

Common reasons submissions get sent back

  • Generic SWMS that don't match the scope you'll do for that client
  • Expired insurance certificates or tickets
  • Policies with no evidence they're used, such as no toolbox talk or inspection records
  • Missing plant documentation

Other platforms work the same way

Avetta, Rapid Global and similar platforms ask for much the same evidence. Build your safety documents properly once, and each new platform becomes an upload job.

Procura builds WHS systems and SWMS from how your crew actually works, as part of your tender documents. Procura is independent and not affiliated with Cm3.
