IJsselmeerdijk foreshore and conventional dike reinforcement

Participation
Not assessed
Project facts checked

Owner reports realization has begun with the lake-side foreshore; conventional dike work planned from early 2027, quantities and acceptance unconfirmed

Project sources

Waterschap Zuiderzeeland identifies a foreshore-first programme with the Boskalis and Van Oord combination. Approximately 12 km of foreshore and 5 km of conventional dike measures form separate treatments within the reinforcement scope.

Project anatomy

Contract scope and delivery roles

Client / authority
Waterschap Zuiderzeeland
Delivery parties
Boskalis and Van Oord, Combinatie IJsselmeerdijk
Contract route
European procurement with provisional selection announced in June 2025 and definitive execution contract reported in July 2025. The cited announcements do not disclose a works contract price.
Execution window
Initial foreshore realization between Maxima power station and Ketelbrug reported in September 2026; existing-dike work between Flevokust Haven and Maxima planned from early 2027. Final acceptance date and measured completion remain unconfirmed.
Works package
Approximately 12 km foreshore with a wave-attenuating dam and shallow-water/reed zone; around 5 km conventional measures including dike raising and exterior revetment replacement. These are announced scope lengths, not accepted constructed lengths.
Marine interfaces
Lake-side material delivery and unloading interact with other waterway users and land access. The dated mobility plan supplies assumptions for nautical logistics; supply-vessel frequency, material tonnage and plant dimensions are not actual deliveries or a selected fleet. Worksite and temporary dike-crossing interfaces require separate execution information.
Commercial evidence boundary
Lake-side and conventional workfronts involve different supply and access interfaces. The June provisional selection and July signed contract are successive procurement milestones. Production rates, final contract price and accepted hydraulic performance are not disclosed by the cited announcements; logistics quantities remain planning assumptions.
