HAROPA PORT is building the first 35 hectares of Port Seine-Metropole Ouest at the Seine-Oise confluence. Phase one opens the first section of the inland basin to the Seine and delivers sheet-pile quays, pile-supported jetties, roads, utilities and landscape works. TED records two contracts totalling EUR 44,612,979.42: Océlian's EUR 34,317,079.42 Lot 1 for civil and port works and Spie Batignolles Le Foll TP's EUR 10,295,900 Lot 2 for roads, networks and landscape. Owner updates move the package beyond award: South Quay sheet piling, west-jetty piling, earthworks, a retaining wall and river loading were active or starting by July 2026.

Project anatomy

Contract scope and delivery roles

Client / authority
HAROPA PORT DT Paris - public port owner, buyer and project authority
Delivery parties
Océlian - Lot 1 winner and group lead for basin earthworks, river works, civil engineering and port structures under contract 2025.60.04, Spie Batignolles Le Foll TP - Lot 2 winner for roads, utilities and landscape works under contract 2025.60.06, SETEC International - project manager named in HAROPA's current site-participant register, Lot 1 official site participants include Terélian, CDES, Botte Fondations, Chantiers Modernes Construction, Eurovia, Leduc TP and other named firms; legal workshares and values are not published, Lot 2 official site participants include Auddicé Seine Normandie, Jean Freon Elagage, Holma, Vallois and Spie Batignolles Valerian; legal workshares and values are not published
Contract route
TED award notice 326986-2026 records two works contracts under one phase-one procedure. Contract 2025.60.04_OCELIAN_LOT 1 concluded on 1 August 2025 at EUR 34,317,079.42. Contract 2025.60.06_SPIE_LOT 2 concluded on 28 October 2025 at EUR 10,295,900. Publication followed on 13 May 2026, making that date a disclosure event rather than either award date. The notice says subcontracting was not known.
Execution window
HAROPA's current programme places phase one in 2025-2028 and the first operators in 2028. Its September 2025 public materials used an end-2027 construction objective before operating release. The July 2026 schedule and work notices supersede the earlier presentation for current sequencing. Neither the programme nor the start of piling proves completed quays, accepted jetties, an opened basin or operational service.
Works package
Lot 1 covers excavation of the first basin section, site levelling and the river and port structures, including quays, pile-supported jetties, banks and the basin opening. Lot 2 covers roads, dry and wet networks, power, lighting, telecoms, water, wastewater, stormwater, public realm, landscape and urban furniture. The owner brochure identifies South Quay sheet piles, east and west jetties, 1.3 million tonnes of excavated material, a basin bypass route and the later removal of the plug separating the basin from the Seine.
Marine interfaces
The new basin enters the Seine beside the existing Ile du Bac riverfront and the Andresy barrage at the Seine-Oise confluence. Delivery joins excavation, sheet-pile quay walls, driven jetty piles, retaining structures, river loading by conveyor, barge export, live inland navigation, temporary access and eventual basin opening. HAROPA reports approximately 60% of excavated material reused on site, 25% moved by river and less than 20% by road; these are logistics plans and reported controls, not a final reconciled material ledger.
Commercial evidence boundary
The two TED lots total EUR 44,612,979.42. HAROPA's September 2025 owner update gives an approximately EUR 150 million whole-project investment and says EUR 62.5 million had been committed to studies and phase-one works, while an older owner overview still shows EUR 122 million of public investment. Those figures describe different dates and boundaries and must not be blended with the two contract awards. Final payments, variations, lot-level earned value and the downstream participant values remain unpublished.

Open this project in the Change Log

HAROPA updated the summer marine-works sequence

The owner moved the record beyond generic construction by reporting active sheet-pile work, retaining-wall and earthworks activity, conveyor loading and the west-to-east jetty piling sequence.

Source

TED published the two-contract phase-one award result

The notice disclosed EUR 44.613 million across Océlian Lot 1 and Spie Batignolles Le Foll TP Lot 2 while preserving their separate contract dates and scopes.

Source

The Lot 2 roads, networks and landscape contract concluded

Spie Batignolles Le Foll TP became the confirmed EUR 10.296 million Lot 2 contractor; this does not assign it the port-structure scope in Lot 1.

Source

HAROPA launched phase-one construction

The owner marked the move from preparatory work into the 35-hectare operational phase, without claiming completed marine structures or service.

Source

The Lot 1 earthworks and port-structures contract concluded

Océlian became the confirmed EUR 34.317 million Lot 1 winner and later owner materials identify it as group lead.

Evidence gap

What remains unverified

Outstanding evidence

  • South Quay sheet-pile installation quantity and accepted wall geometry
  • West and east jetty piling, deck works and structural acceptance
  • Basin excavation, 1.3 million tonne material ledger and river-export reconciliation
  • Retaining wall, basin bypass route and removal of the Seine-side plug
  • Lot 1 and Lot 2 participant workshares, subcontract values and variations
  • Road, rail, river, power, water, wastewater and stormwater interfaces
  • Environmental monitoring, noise, dust, carbon and restored wetlands
  • First-operator handover, navigation release and owner-confirmed service in 2028
