Project anatomy
Contract scope and delivery roles
- Client / authority
- Rijkswaterstaat Programma's, Projecten en Onderhoud
- Delivery parties
- Van den Herik Kust- en Oeverwerken B.V. - signed engineering and execution contractor, Bagger- en Aannemingsmaatschappij Van der Kamp B.V. - named by Rijkswaterstaat as an execution participant for Maasvlakte 2; commercial relationship and package allocation not specified, Assigned vessels, survey team, sand sources and other lower tiers - not identified in the reviewed official record
- Contract route
- For 31205037, Rijkswaterstaat ran an open European Engineering and Construct procedure under UAV 2012. Seven bids were received. TenderNed records Van den Herik Kust- en Oeverwerken B.V. as winner at EUR 16,302,000 excluding VAT and a contract signature date of 10 March 2026. The notice states no subcontracting was declared at award.
- Execution window
- The signed-release schedule spans 3 March 2026 to 15 December 2027. Rijkswaterstaat's current coast-maintenance page places the 1.425 million m3 Maasvlakte 2 beach and foreshore package in September 2026. Physical mobilisation at Maasvlakte 2, Scheveningen and Katwijk remains unconfirmed.
- Works package
- WP1 Scheveningen beach: 435,000 m3 in situ. WP2 Scheveningen foreshore: 690,000 m3. WP3 Katwijk beach: 360,000 m3. WP4 Katwijk foreshore: 1 million m3. WP5 Maasvlakte 2 beach: 1.08 million m3 plus 195,000 m3. WP6 Maasvlakte 2 foreshore: 150,000 m3. Combined indicated design volume is 3.91 million m3. The bestek's MARS measurement requirement adds 15% to each package's in situ design quantity for contractual measurement control; it is not an additional public completed-volume claim.
- Marine interfaces
- The contract combines three coast sectors, paired beach and underwater packages, TSHD production, bottom discharge and pipeline placement, hydrographic and topographic surveys, public beach access, environmental controls and interfaces with the Port of Rotterdam and Maasvlakte wind-turbine area. Vessel and package sequencing will determine mobilisation efficiency and navigational coordination.
- Commercial evidence boundary
- EUR 16.302 million is the signed legal contract value. The 3.91 million m3 in situ design total excludes any inference that MARS control quantities are additional accepted scope. The record leaves the Van den Herik-Van der Kamp commercial structure, package pricing, vessel day rates, certified progress, variations, payments and final account undisclosed.
