Procedure

Features
The Procurement Specific Questionnaire (PSQ) (including Conditions of Participation) is available within the Defence Sourcing Portal (DSP) and will be used to down-select to 5 suppliers to be invited to Tender. This will also include the assessment of whether a supplier, its connected persons, associated persons or any intended subcontractors are excluded or excludable persons under the Procurement Act 2023. A clarification process will be used during the PSQ period to allow suppliers to seek clarification from the Authority. 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. An Invitation to Tender (ITT) will be issued to those successful at PSQ. A clarification process will be used during the tendering period to allow suppliers to seek clarification from the Authority. A summary of the award criteria is in this notice and will be explained in the Tender Evaluation Strategy, which will be published in the DSP, with the ITT. The Authority reserves the right to refine the award criteria before and - where negotiation/final tenders are used - during the Tender period in accordance with section 24 of the Procurement Act 2023. This may include revision to the weightings of the sub-criteria. The following supplementary processes may be used, with further details set out in the additional tender documents; • Clarifications - during the tender evaluation period • Negotiations - following evaluation of the Tender • Final Tenders - following negotiations, if used • Preferred Supplier Stage - to confirm solutions and/or finalise the draft contract. The Authority reserves the right to amend the procurement, where such amendment would not be substantial, as follows, including and not limited to; • amendments to the tender documents which may provide clarification • refining the specification as the competitive flexible procedure progresses • reducing timescales. If any amendments are made, the Authority will consider whether any applicable tender deadlines should be revised, and whether any tender documents or notices need to be re-issued. The Contracting Authority reserves the right to directly award a contract for similar goods or services without further competition pursuant to Schedule 5 paragraph 8, including to other parts of the Ministry of Defence. A tenderers' conference is to be held online via MS teams for the 5 potential providers who are given an ITT. The date will be confirmed when the ITT is released on the Defence Sourcing Portal. The Authority will issue invitations to the tenderer’s conference using the messaging facility on the Defence Sourcing Portal. Further details of the conference can be found within the DEFFORM 47.
