Other Requirements

Reduction Criteria
Tenderers’ response to the PQQ will be scored in the order as outlined in the sourcing portal, with those sections marked as Pass/Fail where the Tenderer will either meet or fail to meet the minimum criteria. All prospective Tenderers are required to pass each question within the SWS PQQ response forms. A full response to Qualification Envelope is required, except where indicated. Failure to respond fully to any required question in this section or not being able to meet the minimum requirement will result in the submission being non-compliant and being excluded from the process, except where the SWS Commercial Head determines that a genuine error has been made, and a correction may then be permitted. Sub-criteria applies to the technical evaluation, as specified within the IITT document.

Selection criteria

Criteria

Criterion 1
Type
economic
Description
Southern Water is required by its investors to ensure that any key supplier has good economic and financial standing. A CreditSafe check will be used for this purpose, together with other background checks if needed, at the discretion of the Client. A Tenderer may be rejected if the recommended annual contract value for their company on CreditSafe is below the proposed annual value of the contract. The annual value of the contract is calculated by dividing the estimated total value by the initial period. The Creditsafe value for each lot is specified within the IITT document. Where a contract is tendered, the annual value would also be divided by the number of Service Providers expected to be appointed; this would not always be an equal division, as different lots may have different values. If a bidder fails this test, and only publishes abridged accounts, Southern Water may allow the bidder to proceed. This would be on the basis of providing turnover data that satisfies the annual contract value accounting for less than a half of their annual turnover; and do not have an adverse risk score on CreditSafe. Alternatively, a Parent Company Guarantee or bank Guarantee may be accepted, however it would need to fulfil the above.
