Saint-Malo Terminal du Naye Lot 2 marine works

Tracked excavator carrying out lock-guide demolition under the Terminal du Naye Lot 2 marine works package in Saint-Malo

Ports de Bretagne - Région Bretagne; exact Terminal du Naye lock-guide demolition and Lot 2 marine works

Région Bretagne awarded the second marine-works lot of the Terminal du Naye modernisation to the ETPO, Merceron TP and Avenir Déconstruction group. The package removes the old lock guides and berth 1 Ro-Ro ramp, builds replacement reinforced-concrete caisson guides and includes maintenance dredging of the outer harbour and lock approaches while keeping a live ferry gateway operating.

Project anatomy

Contract scope and delivery roles

Client / authority
Région Bretagne, acting through the Conseil Régional for the Port of Saint-Malo Terminal du Naye
Delivery parties
ETPO - lead contractor in the awarded Lot 2 group and lead for the December 2025 Ro-Ro ramp removal, Merceron TP - marine-works and dredging member of the awarded Lot 2 group; no narrower project allocation is published, Avenir Déconstruction - deconstruction member of the awarded Lot 2 group, SCE Aménagement & Environnement and Fondouest - engineering group identified by the owner for Lot 2, SCE and Créocéan - environmental owner-assistance group identified by the owner, Sarens - named by the owner for transfer and skidding of the removed Ro-Ro ramp; no broader Lot 2 role is inferred, EDEIS - port-concession operator whose tug supported the ramp-removal marine operation; not a Lot 2 works contractor
Contract route
The Conseil Régional used an EU works procedure for Lot 2. TED notice 113250-2025 opened the competition and award notice 664551-2025 records ETPO, Merceron TP and Avenir Déconstruction as winners, a EUR 23,594,961.67 result value and contract conclusion on 6 October 2025. The owner announced the group and the two-year mission on 20 October 2025.
Execution window
The owner framed Lot 2 as a two-year assignment beginning in late 2025. The 60-metre, 270-tonne Ro-Ro ramp was removed in December 2025; demolition of the old lock-guide structures was active in March and April 2026, using a monobloc pontoon and 300-tonne and 120-tonne cranes. The broader phase-one terminal programme targets early 2028, but no Lot 2 completion or acceptance date has been published.
Works package
Remove the two existing lock-guide structures and berth 1 Ro-Ro ramp; fabricate reinforced-concrete replacement guide caissons in dry dock; float, tow and immerse the caissons; and perform maintenance dredging in the outer harbour and lock approaches. Owner publications say deconstruction and dredged materials are to be reused on site, including dried sediment in the new structures, without sea disposal.
Marine interfaces
Lot 2 combines demolition, heavy lifting, caisson construction, tow-out, immersion and maintenance dredging at a working ferry terminal. The owner describes a monobloc pontoon, two large cranes and port-concession tug support around the demolition sequence. Water-quality controls, sediment containment, adapted dredging tools and marine-mammal monitoring sit alongside ferry access and lock-operation constraints.
Commercial evidence boundary
The exact TED award is EUR 23.59496167 million for Lot 2. It is not the EUR 150 million whole-terminal programme or the EUR 87 million nautical programme envelope. The approximately 45,000 cubic metres reported after the first 2025 dredging campaign and the approximately 90,000 cubic metres covered by the wider environmental authorisation are separate scope indicators; neither is a measured Lot 2 quantity or a basis for a contract unit rate.

Owner documented active lock-guide demolition

One of the two old guide structures was being dismantled under SCE engineering oversight by the ETPO-Merceron-Avenir group. This confirms physical Lot 2 construction but not completion of both structures or caisson installation.

Source

The old berth 1 Ro-Ro ramp was removed

The owner recorded removal of the 60-metre, 270-tonne ramp, led by ETPO with Avenir Déconstruction, Sarens and port tug support. The operation closed a visible demolition step without establishing full Lot 2 acceptance.

Source

Lot 2 concluded with the ETPO-led group

TED records ETPO, Merceron TP and Avenir Déconstruction as winners at EUR 23.59496167 million. The award created a bounded two-year demolition, caisson and maintenance-dredging package inside the wider terminal programme.

Evidence gap

What remains unverified

Outstanding evidence

  • Completion of both old lock-guide demolitions
  • Fabrication, launch, tow and immersion dates for the replacement caissons
  • Maintenance-dredging mobilisation, measured volume and achieved depths
  • On-site reuse ledger for dredged sediment and deconstruction material
  • Post-dredge hydrography and navigation acceptance
  • Ferry-operating restrictions and marine-access sequencing
  • Subcontractors for caisson fabrication, heavy lifting, dredging, survey and monitoring
  • Owner completion certificate and final account
