Stage 1 - Conditions of Participation (CoP):
Interested suppliers submit a COP Questionnaire. Responses are assessed against defined pass/fail Selection Criteria to determine whether suppliers meet Yorkshire Water's minimum requirements. Yorkshire Water may conduct one or more rounds of Selection and reserves the right to shortlist suppliers progressing to subsequent stages.
Stage 2 - Contractual Compliance:
Shortlisted suppliers will be invited to review and, where permitted, comment on the Proposed Contract. Yorkshire Water will refine and finalise the contract terms during this stage. Only suppliers who accept the final contract terms will progress to the ITT stage.
Stage 3 - Invitation to Tender (Quality & Commercial):
Suppliers will submit detailed quality and commercial tenders, which will be evaluated in accordance with the award criteria set out in the ITT documentation.
Following evaluation, Yorkshire Water will identify the most economically advantageous tenders and award places on the Technical Services and Assurance Framework.
