Might have missed the bus here, but in case it's still useful:
H&S PQ is a good example of 'demonstrated safety work' (Rae & Provan, 2019).
It's the very first (and least important) stage in a Supplier Selection Process. It really only can assure the buyer of services that the suppliers who are able to tender for work have an appropriate H&S management programme (suitable and sufficient for the type of business they are).
Research shows that work-related accident and fatal accident rates can be significantly reduced by implementing a suitable OHSMS (Yoon et al. 2013).
A written and comprehensive H&S management programme is effective in helping reduce H&S risk for construction businesses (Hallowell and Gambatese 2009)
Investment in a suitable H&S management programme is shown to be a good investment (Bayram, Ünğan, and Ardıç 2017)
The attention created by the adoption of a management programme opens possibilities for giving priority to key OHS issues in the business (Uhrenholdt Madsen et al. 2020)
Using system levers to require businesses to have a structured and proportional H&S management programme tends to have positive safety benefits (Frick and Kempa 2011)(Frick 2011)
The problem is that pre-qualification processes are overcooked, overcomplicated, expensive, confusing, and bureaucratic.
Prequalification is the 'ticket to the dance' - 'getting a date' is a different conversation and where the energy and effort should be.
Tōtika has been developed to de-clutter H&S Pre-qualification in NZ and move the conversation forward.
