The search for a main construction partner is due to start in summer of 2023 with contract award anticipated in early 2025.
The Environment Agency has already developed outline design proposals and an initial procurement strategy for the phased 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.
It aims to test this strategy and the outline design proposals through a series of market engagements while undertaking the Environmental Impact Assessment and preparing for the consenting process.
The scope of the construction partner contract and main works include the detailed design and construction of new flood channel built in two channel sections.
River Thames Scheme works
- First section (Runnymede channel) – Egham Hythe to Chertsey
- Second section (Shepperton channel) – Laleham to Shepperton
- Increasing the flow capacity of existing Sunbury, Molesey and Teddington weirs
- Increasing the capacity near the Desborough Cut
- Utility diversion works
- New road and pedestrian bridges to accommodate the new channel sections
- Demolition of residential properties to make way for the Runnymede channel
- Earthworks including excavation and disposal of material
By June 2023, the Environment Agency aims to provide a final overview of the planned tender process and tender requirements prior to issuing the formal contract notice and tender documents.
