Cm3 is Australia's leading online Contractor OHS/WHS Prequalification system. Cm3 addresses the need for both contractors and the organisations they conduct work for to demonstrate contractor health and safety management capabilities, along with providing assistance for organisations to better manage their contractors around health and safety requirements.


Our role

Thomson Bridge was appointed as a specialist High Voltage advisor to Cm3 to prepare a set of nationally applicable high voltage safety management system questions for the power generation, transmission, distribution and electrical infrastructure industries.

This work has provided our Company with a strong understanding and respect for the Cm3 platform.

We are currently in the process of developing standardised documentation and associated procedures to assist other contractors who are seeking prequalification via this platform.
