❓ Question regarding the alliance procurement process for a major infrastructure project, specifically concerning proponent participation, evaluation criteria, and probity oversight.

I refer to Infrastructure WA’s Major Infrastructure Proposal Assessment, which references delivery of the project under an alliance contract model and highlights the need to adequately manage commercial and delivery risks prior to final contract award, and I ask:(a) how many proponents participated in the alliance procurement process;(b) what evaluation criteria was applied; and(c) was independent probity oversight engaged?
