## Summary

The Cardiff Council is currently conducting a tender for a five-year maintenance dredging contract for the Outer Harbour and Approach Channel, spanning from 2022 to 2027. This is classified under the works category and includes key activities such as dredging and harbour construction works. The tender process has reached the award stage, with the contract valued at approximately £3,188,340, awarded to Boskalis Westminster Ltd. The original tender submission deadline was on 18th May 2022, following a period for clarifications up to 6th May 2022. The contract is set to serve a critical navigational purpose, helping maintain safe access for vessels in the Cardiff Bay area.

This tender offers significant business opportunities, particularly for companies involved in dredging, harbour construction, and maintenance services. Given the scale and duration of the contract, firms specialising in environmental and social value initiatives may also find this a suitable opportunity, as the buyer intends to include community benefits in the contract performance. Suppliers with capabilities in large-scale dredging campaigns, alongside those who can demonstrate a commitment to social responsibility, will be well-positioned to compete for this contract.

## Notice

The Outer Harbour of the Barrage provides a safe haven for boats entering the Inland Bay and it was designed to allow access and egress for boats at all states of the tide. Siltation of the harbour is a continuing maintenance liability that was anticipated when the barrage was constructed. The Harbour Authority has a duty under the Cardiff Bay Barrage Act to maintain the Outer Harbour and Approach Channel as a navigational route to the Inland Bay and also has to comply with the requirements of the dredging licence. Dredging is therefore required twice yearly at times agreed with Natural Recourses Wales. Dredging campaigns currently cost in the region of PS250,000 to PS300,000 and remove around 70,000cubic metres of silt.
