two.1.4) Short description

This notice is only an invitation to express interest to participate in a market engagement exercise for the River Thames Scheme. The Environment Agency and Surrey County Council, through a collaboration partnership, are issuing this PIN for the purpose of seeking organisations that wish to take part in Market Engagement exercises, Phase 1 to Phase 5 before we start a formal procurement process, for which a separate contract notice will be issued. Organisations should ensure that they express their interest for all the relevant phases of the market engagement process so that their intent is correctly noted by the Environment Agency.

The Environment Agency has already developed outline design proposals and an initial procurement and contract strategy for the delivery phases of the River Thames Scheme, which will involve a range of works to reduce flood risk from the River Thames between Egham Hythe, Staines and Teddington weir. The Environment Agency intends to test this strategy and the outline design proposals through Phase 1, 2 and 3 of the Market Engagement whilst undertaking the Environmental Impact Assessment and preparing for the consenting process.

Our current project programme intends to initiate publishing a contract notice and the tender documents in the autumn of 2022 with contract award anticipated in summer 2024 (subject to required approvals). We are seeking feedback from the supply market to help us shape our current strategy, design, contracting and risk management proposals to ensure delivery in the most efficient and effective way.
