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 between 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 and whether the suppliers are UK suppliers under the Procurement Act. A clarification process will be used during the PSQ period to allow suppliers to seek clarification from the Authority. Within the PSQ there are Pass/Fail questions and suppliers are required to pass all of the questions to be eligible to be invited to Tender. 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 • Supplier presentations / site visits - during the Tender, and Tender Evaluation period • 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.
