Dredging Framework

Normandy turns one dredging framework into eight evidence chains

Ports de Normandie / F. Monier; Caen-Ouistreham operating-port context, not evidence of framework execution

The Normandy maintenance-dredging procurement is one procedure but not one undifferentiated job. Eight call-off lots divide TSHD, grab or pontoon, stationary-suction and marine-levelling work across seven ports and four prime award chains. TED confirms the contracts and EUR 6.876 million aggregate winning-tender value; the port authority's own deliberation supplies the quantity bands. Neither source proves that those maxima have been ordered or dredged.

The award resolves primes without resolving execution

TED controls the procedure, contract identifiers, awardees, aggregate value and dates. Ports de Normandie's committee record controls the lot-by-lot quantity and hour bands. The authority's procurement page explains its consultation and approval process. Call-off orders, mobilisation, downstream subcontracts, production ledgers and accepted depths remain unpublished.

Lot-level accounting prevents four common overstatements

A framework creates capacity to order work, not evidence that work occurred. Each future call-off must be tied to a port, lot, plant, ordered quantity, measured quantity, sediment route, survey and acceptance record. This also prevents false subcontractor attribution: Eco Systemes de Dragage/Van den Herik, Marc SA, CCI Caen Normandie and Compagnie de Remorquage de Dieppe are separate prime award chains in the public record.

Evidence conclusion

Individual call-off awards now control delivery visibility

Outstanding evidence

  • Port- and lot-specific 2026 call-off orders
  • Plant identity and mobilisation dates
  • Ordered, dredged and accepted quantities
  • Pre- and post-dredge hydrographic surveys
  • Sediment classification and destination
  • Named downstream marine and environmental parties
  • Annual renewal and revised quantity bands
  • Payments and final account by authority and lot
