Stage 2: Tenderers who pass all PSQ gateways submit a full ITT response evaluated on quality (60%) and commercial (40%) criteria, with a minimum score of 3 required on each quality question. The Crown Estate reserves the right to conduct a discretionary negotiation stage with the two highest-ranked Tenderers prior to preferred bidder selection, following which a Best and Final Offer may be requested. The contract will be awarded to the most advantageous tender.\nThe PSQ can be accessed via: https://secure.sourcedogg.com/profile/676e86f0-50b5-4563-b7b6-529dcfeb28b7/requests/78622\nThe ITT can be accessed via: https://secure.sourcedogg.com/profile/676e86f0-50b5-4563-b7b6-529dcfeb28b7/requests/78623\nThe PSQ and ITT are issued simultaneously. Tenderers may therefore begin preparing their ITT response before receiving the outcome of their PSQ assessment. Tenderers should be aware that they do so entirely at their own risk. The Crown Estate will evaluate PSQ responses before ITT responses. A Tenderer that fails any PSQ gateway question - binary (Part E) or scored (Part F) - will be excluded from the procurement and its ITT response will not be evaluated, regardless of the stage of completion or submission of that ITT response.

under the Procurement Act 2023. The process comprises two stages issued simultaneously. Stage 1: Tenderers submit a Procurement Specific Questionnaire (PSQ) containing hard binary gateway questions (E1-E2) and scored gateway questions (F1.1-F1.6, minimum score 3 to pass). A fail on any gateway results in exclusion. Stage 2: Tenderers who pass all PSQ gateways submit a full ITT response evaluated on quality (60%) and commercial (40%) criteria, with a minimum score of 3 required on each quality question. The Crown Estate reserves the right to conduct a discretionary negotiation stage with the two highest-ranked Tenderers prior to preferred bidder selection, following which a Best and Final Offer may be requested. The contract will be awarded to the most advantageous tender.\nThe PSQ can be accessed via: https://secure.sourcedogg.com/profile/676e86f0-50b5-4563-b7b6-529dcfeb28b7/requests/78622\nThe ITT can be accessed via: https://secure.sourcedogg.com/profile/676e86f0-50b5-4563-b7b6-529dcfeb28b7/requests/78623\nThe PSQ and ITT are issued simultaneously. Tenderers may therefore begin preparing their ITT response before receiving the outcome of their PSQ assessment. Tenderers should be aware that they do so entirely at their own risk. The Crown Estate will evaluate PSQ responses before ITT responses. A Tenderer that fails any PSQ gateway question - binary (Part E) or scored (Part F) - will be excluded from the procurement and its ITT response will not be evaluated, regardless of the stage of completion or submission of that ITT response. The Crown Estate accepts no liability for any costs incurred by a Tenderer in preparing an ITT response that is not evaluated as a result of PSQ failure. Tenderers must not assume that submission of an ITT response indicates that their PSQ has been assessed as a pass." } ] }, "submissionMethodDetails": [ { "releaseID": "065346-2026", "releaseDate": "2026-07-10T16:43:47+01:00", "releaseTag": [ "tender" ], "value": "The PSQ can be accessed via: https://secure.sourcedogg.com/profile/676e86f0-50b5-4563-b7b6-529dcfeb28b7/requests/78622\nThe ITT can be accessed via: https://secure.sourcedogg.com/profile/676e86f0-50b5-4563-b7b6-529dcfeb28b7/requests/78623\nThe PSQ and ITT are issued simultaneously.
