"features": "Southern Water will conduct this procurement under the Competitive Flexible Procedure, as defined in the Procurement Act 2023. This approach enables a streamlined and adaptable process, designed to ensure compliance while promoting fair competition and market engagement. This procurement will follow a single-stage process. Tenderers will be required to complete Pre-Qualification Questionnaire (PQQ), which sets out Southern Water's standard mandatory requirements for tendering relating to (but not limited to) Tenderers' legal and financial capacity, as well as their basic capacity and capability to deliver the contract. PQQ establishes the minimum Conditions of Participation. There is no scored technical section within the PQQ, which means the ITT part of the tender is opened to all Tenderers who meet the Condition of Participation. The PQQ clearly identifies any questions that may result in exclusion from further process. Invitation to Tender (ITT) will be issued concurrently with the PQQ. Tenderers are expected to submit both components. If the Tenderer fails to meet the Conditions of Participation, their ITT submission would be invalidated. The ITT part of the tender consists of Technical and Commercial Envelopes. Evaluation criteria and weightings will be detailed within the tender documentation. The entire procurement process will be conducted electronically via Southern Water's e-sourcing platform, Jaggaer: https://southernwater.bravosolution.co.uk Tenderers must be registered on: Jaggaer e-sourcing portal Central Digital Platform, as required under the Procurement Act 2023"
