Competitive flexible procedure description
Southern Water Services Limited (SWS) 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. The procurement will follow a three-stage process.
Tenderers will be required to complete a 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 capability to deliver the contract.
The PQQ establishes the minimum Conditions of Participation. There is an additional scored technical section within the PQQ. The PQQ envelope clearly identifies any questions that may result in exclusion from the process. SWS will take a maximum of five top-scoring Tenderers through to the next stage of the process.
The Invitation to Tender (ITT) will be the second stage of the procurement process. It will consist of Technical and Commercial envelopes. Details of the ITT, including the questions, evaluation criteria, and the weightings of the envelopes, will be published to the qualified Tenderers at the start of the ITT stage.
The top two scoring Tenderers from the ITT stage will be invited to a two-step Demo stage. Details of this stage, including the demo tasks, will also be published at the start of the ITT stage to all Tenderers that qualify for the ITT stage.
