Société Publique de l'Agglomération Dunkerquoise awarded three Port de Plaisance du Grand Large packages. Eiffage Travaux Maritimes et Fluviaux won Lot 1 marine civil works at EUR 3,739,243; Atlantic Marine won Lot 2 floating pontoons at EUR 2,083,000; and the Lot 3 winning tender, named as Ramery Travaux Publics in consortium with Montanier, was EUR 2,777,007. Those legal awards define the package map and 24-month planned periods, but they do not prove field mobilisation, identify Lot 3's declared lower-tier subcontractors or explain the difference between the three tender values and the notice-level total.

Project anatomy

Contract scope and delivery roles

Client / authority
Société Publique de l'Agglomération Dunkerquoise (SPAD), acting on the Grand Large marina works
Delivery parties
Eiffage Travaux Maritimes et Fluviaux - Lot 1 marine civil works, EUR 3,739,243; six electronic submissions, Atlantic Marine SAS - Lot 2 floating pontoons, EUR 2,083,000; two electronic submissions, Ramery Travaux Publics - Lot 3 contract reference, EUR 2,777,007; winning tender named a consortium with Montanier and five electronic submissions, Unnamed Lot 3 subcontractors - the winning tender declares EUR 678,449 or 24% for subcontracting, but the cited award XML gives no company names, Lot 4 networks and electricity contractor - not established by the cited three-lot procedure
Contract route
SPAD published open procedure 47258-2026 on 22 January 2026 with a 27 March tender deadline. The wider operation was divided into four lots: this formal procedure covered Lots 1-3, while Lot 4 networks and electricity was to run separately under an adapted procedure. Award notice 542678-2026 records Lot 1 and Lot 2 award decisions on 15 June, Lot 3 on 30 June, and contract issue or conclusion on 30 June 2026 for all three.
Execution window
Each of Lots 1-3 carries a 24-month planned duration. The award notice does not publish a start date, notice to proceed, site-possession record, current programme, completion date or acceptance event. Counting 24 months from the 30 June contract date would be an inference, not an official delivery schedule.
Works package
Lot 1 covers removal of existing breakwater modules and unusable piles, new guide piles, new breakwater modules and equipment, a lifting basin, a collector-gangway access platform and acoustic monitoring. Lot 2 covers phased permanent pontoons, temporary removal and reinstatement, catways, six gangways including a utility gangway, safety equipment and relocation of the pilots' pontoon. Lot 3 covers earthworks, trenches, refuelling pontoon and networks, ducts, careening and storage areas, roads and pavements, lighting, fencing, access control, signage, waste facilities and associated equipment.
Marine interfaces
The live interface joins pile and wave-attenuation work, floating pontoons, six gangways, marina traffic, pilots' berthing, lifting and careening operations, fuel and utility services, water treatment, access control and environmental noise monitoring. The official Pointe des Alliés concept places these works inside a broader 450-berth marina and 10,000 m2 technical-zone plan, but that wider urban and waterfront programme is not the disclosed scope of the three contracts.
Commercial evidence boundary
The award XML provides a lot ledger but not a reconciled programme account. Lot-level payable amounts total EUR 8,599,250; the top-level notice amount is EUR 10,488,651. The XML contains no bridge between them. Lot 3 also declares EUR 678,449, or 24%, of subcontracting without naming the recipients. Montanier appears in the winning-tender reference as Ramery's consortium partner and should not be relabelled as the unnamed subcontractor. Payments, variations, final account and the Lot 4 award value remain undisclosed.

The three-lot award notice was published

The result disclosed winners, lot values, bidder counts and Lot 3 subcontracting while leaving mobilisation and the total-value reconciliation open.

All three works contracts were concluded

Lot 1 went to Eiffage TMF, Lot 2 to Atlantic Marine and the Lot 3 winning tender named the Ramery-Montanier group; contract dates do not prove site start.

SPAD opened the three-lot works competition

The notice separated marine civil works, floating pontoons and landside systems from a fourth networks-and-electricity procurement with its own award path.
