Frioul East breakwater rehabilitation and rock spur

Elevated view of Frioul marina and the full East breakwater protecting the basin from the Mediterranean

Métropole Aix-Marseille-Provence; exact Frioul East breakwater context before the 2026 main-contract mobilisation evidence

Métropole Aix-Marseille-Provence is strengthening the Frioul marina basin at Marseille by rehabilitating the approximately 320-metre East breakwater and constructing an internal rock spur. TED records a EUR 19,589,919 works contract concluded with Océlian Corse Méditerranée, GTM Sud, Eurovia, Jean Negri & Fils and TP Spada after five tenders. The owner's design material describes about 90,000 tonnes of rock, reuse of the historic core and habitat measures, while the procurement warns that island access, waterborne material transport and work inside an operating port constrain delivery.

Project anatomy

Contract scope and delivery roles

Client / authority
Métropole Aix-Marseille-Provence as port infrastructure owner and contracting authority
Delivery parties
Océlian Corse Méditerranée - works-group lead / mandataire and co-awardee, GTM Sud - works-group co-awardee, Eurovia - works-group co-awardee, Jean Negri & Fils - works-group co-awardee, TP Spada - works-group co-awardee, EGIS Ports - designer and maître d'œuvre named in the owner brochure, Downstream quarry, marine transport, survey, diving, ecological monitoring, concrete, services and other specialist subcontractors - publicly unnamed
Contract route
Métropole Aix-Marseille-Provence opened procedure f134c1e4-d81d-4d9f-9e90-c37980ab2ce8 in 2025 for marine works under CPV 45244000, 45220000, 45200000 and 45243300. The authority concluded Contract Z250608F00 on 2 February 2026 after receiving five tenders. The 9 February award notice records a single five-company winning group and a EUR 19,589,919 total contract value. Its subcontracting field reports no declared subcontracting; this is an award-date disclosure, not proof that no lower-tier party can later be appointed.
Execution window
The consultation-stage brochure described a three-year construction period and a 2025 completion ambition. The works contract was not concluded until February 2026. A June 2026 owner financial report says the breakwater programme continues during 2026 but gives no main-contract notice to proceed, mobilisation date, physical progress percentage or revised handover date.
Works package
Rehabilitate the roughly 320-metre East breakwater by anchoring a new rock shell into the degraded historic structure, strengthening the toe and reusing suitable existing core material; construct an internal rock spur, described at approximately 100 metres in the 2019 programme record, to reduce easterly wave penetration. The owner brochure gives an indicative 90,000 tonnes of rock and includes public-space, utility, landscape, ecological-design and Posidonia protection measures, including three-dimensional habitat modules.
Marine interfaces
Frioul is an island port reached from Marseille by water. Tender clarification tells bidders to account for waterborne delivery of construction materials, constrained access, active-port operations and island conditions. The works must preserve marina use while coordinating rock transport and placement, the existing masonry and rubble core, a military-pontoon interface, underwater and terrestrial survey controls, Posidonia protection and environmental monitoring.
Commercial evidence boundary
The EUR 19,589,919 figure is the awarded works-contract value and five submissions were received. The owner's EUR 32 million figure is an earlier whole-project estimate; EUR 2 million was an initial studies allocation; EUR 1.3 million was programme expenditure executed by 31 December 2025, before conclusion of the principal works contract. None of those three figures is the contract's paid-to-date amount, certified production or final account.

Owner financial report kept the programme active in 2026

The report says the full Frioul breakwater rehabilitation continues and records EUR 1.3 million executed by 31 December 2025. It is programme-level evidence, not proof that the February 2026 principal works contract had mobilised.

TED published the five-company works award

The award notice confirms Contract Z250608F00, a EUR 19,589,919 value, five received tenders and the Océlian, GTM Sud, Eurovia, Jean Negri & Fils and TP Spada winning group.

Source

The authority concluded the principal marine-works contract

Contract conclusion closes the procurement award gate but does not by itself establish a notice to proceed, mobilisation, rock delivery or accepted physical progress.

Source

Tender clarification exposed the island logistics

The notice directed bidders to account for waterborne material transport, constrained access, active-port operations and island conditions, making logistics and live-port coordination central execution risks.
