We are particularly interested in engaging with suppliers who can demonstrate: • Strong technical capability across all stages of capital design • Experience delivering projects within the regulated water sector • Commitment to safety, sustainability, and value optimisation. Further information on the procurement process, associated timelines, and the Contracting Authorities' expectations regarding collaborative and innovative approaches to scheme development will be shared in due course.

Description
The Contracting Authorities intend to undertake preliminary market engagement (PME) through a supplier engagement event ("Supplier Day").

The purpose of this PME is to: • Assess market capacity and appetite to deliver works at the scale envisaged • Formally inform supply chain about the tender process e.g., timeframes and lotting strategy • Identify opportunities to support SME participation and supply chain engagement Information gathered during this engagement may be used to inform the final procurement strategy and tender documentation. Following completion of the PME, the procurement is expected to progress to the publication of a UK4 notice. Further details, including the tender documentation and proposed lotting strategy, will be provided through the UK4 notice. All information contained within this notice is indicative only and subject to change. This notice does not constitute a call for competition, and participation in this engagement is not a prerequisite for participation in any future procurement stages. The Contracting Authorities reserve the right to amend the procurement strategy, including the number and structure of lots, to ensure that the market is able to meet the Contracting Authorities' requirements. The final procurement approach will be confirmed within the tender documentation. The estimated framework value of £200 million is provided for indicative purposes only and may be amended as the procurement develops. Caveats: • All description, values, dates and timelines are indicative at this stage • This notice is NOT a Call for Competition • No party will be prejudiced in the later stages of this procurement by their response or lack thereof to this notice and response to this notice is not a pre-requisite of the tender • Contracting Authorities shall have no liability, in particular liability for costs, or responsibilities arising out of the notice • The Central Product Classifications ('CPC's') chosen are those we consider to be most applicable, but these include sub-sets within that code and the code specified is not exclusive
