## Summary

The Environment Agency has awarded a contract for the project titled "Grand Redoubt Gate 1" to JT Mackley & Co. Ltd. This project, classified under River regulation and flood control works, involves the replacement of a tidal flap at Redoubt Sluice in Dymchurch, located in the South East of the United Kingdom, specifically postal code TN31 7PH. The contract, valued at £65,337.90, commenced on 28 August 2024 and is set to conclude on 25 September 2024. The procurement method used was selective, specifically a call-off from a framework agreement. The tender described involved the provision of labour, equipment, and materials required for the specified works, with the procurement stage currently marked as Award.

This tender represents a significant opportunity for businesses specialising in flood control and river regulation works, particularly those capable of delivering bespoke equipment and materials such as plastic composite flaps. The project’s requirement to allow elvers' passage upstream and address defects in the southern tidal penstock suggests an opportunity for innovative solutions. Small and medium-sized enterprises (SMEs) are encouraged to compete, enhancing their capabilities in specialised environmental engineering. Businesses already part of relevant framework agreements may find this opportunity particularly advantageous, as it leverages established procurement relationships.

## Notice

ECSC for labour, equipment and materials re: the replacement of one tidal flap within the tidal basin at Redoubt Sluice in Dymchurch (the northern flap). The Contractor shall provide a plastic composite flap of the same size and configuration as the existing flap. The new flap shall be shimmed to permit some leakage, so allowing the passage of elvers upstream. The Contractor shall inspect the southern tidal penstock and suggest remediation to remedy a defect; the flap only opens halfway.
