Project anatomy

Contract scope and delivery roles

Client / authority
London Gateway Port Limited, the DP World port company and statutory harbour authority
Delivery parties
Jan De Nul nv - selected dredging supplier under the latest UK6 award notice, No lower-tier subcontractor, survey provider, disposal operator or support-vessel provider is identified in the reviewed public record
Contract route
Utilities competitive flexible procedure under the Procurement Act 2023. The tender allowed up to four suppliers into the tender stage and weighted commercial evaluation at 70% and technical quality at 30%. It estimated GBP 10 million excluding VAT for a 1 October 2025 to 2 March 2026 period, with a possible one-month extension. A 14 October award notice selected Jan De Nul at GBP 57 million for an estimated 3 November 2025 to 1 November 2027 period with a possible extension to November 2028. The 19 December notice retained the same supplier and value but labelled the result Contract 2 and revised the estimated period to 6 January 2026 through 30 December 2027. No UK7 contract-details notice was located in the reviewed procurement chain by 3 August 2026.
Execution window
The latest public award notice gives an estimated 6 January 2026 start and 30 December 2027 end. Those dates are not treated as proof of signature or field execution. Earlier notice dates remain procurement history: the original tender expected a six-month 2025-26 campaign, while the first award expected a November 2025 start and allowed extension into November 2028.
Works package
Maintain deep-draft access by dredging designated areas within the Yantlet, including Sea Reach and the manoeuvring area, the Sunk and Knock John Channel, and by removing high spots from berth pockets. London Gateway may also instruct dredging at Yantlet/West Oaze and Black Deep. The works include mobilisation and demobilisation of dredging equipment. The C2526 notices do not publish a bill quantity, target depth, dredging method, vessel, sediment classification, disposal or beneficial-use route, survey specification or acceptance criterion.
Marine interfaces
The works sit inside a live Thames Estuary navigation system serving an operating deep-water terminal. DP World currently lists four berths, 1,690 metres of quay, 16.5 metres chart-datum depth alongside and a tidal approach range of 14.5 to 21 metres, while Berths 5 and 6 are being developed separately. Dredging must therefore protect deep-draft access and berth availability without conflating this maintenance award with the separate quay and yard expansion packages.
Commercial evidence boundary
The latest GBP 57 million award value is 5.7 times the tender estimate, but the public notices also lengthen the period and the first award mentions possible maintenance and capital dredging. Without the priced scope, contract-details notice, instructed quantities, rate schedule, change record and final account, the difference is not evidence of overrun, final spend or a unit-rate benchmark. The same value in two award notices is one procurement result, not two contracts to be added together.
