Conditions of participation

Within the PSQ there are a mix of questions which are Pass/Fail and Scored. A ‘Fail’ will result in the potential provider being excluded from further participation in the tendering process.

For those suppliers who Pass all of the Pass/Fail questions, their overall technical score will determine their ranking. Those ranking in the Top 5 will be invited to Tender.

Where there is a tie at Position 5, the decision on which supplier will be Invited to Tender will be based initially on the highest score on question 1 of the Technical Conditions of Participation.

Where this still results in a tie, the decision will be based on the highest score for question 2. This will continue sequentially down the list for Questions 1 to 4 until a supplier is selected for 5th place. If this sequential process does not result in a clear 5th place then the Authority reserves the right to proceed to tender with additional suppliers who share equal 5th position.
