Fa. Gebr. Van der Lee signed Rijkswaterstaat contract 31205036 at EUR 8.199 million. The final design allocates 1.74 million m3 across Westkapelse Zeedijk, Westkapelle-Zoutelande and Breezand, while the first site, assigned dredger, borrow area and physical start remain undisclosed.

Contract signature fixes the Van der Lee role

TenderNed establishes the signed EUR 8.199 million award and execution period. The final bestek establishes 550,000 m3 at Westkapelse Zeedijk, 750,000 m3 at Westkapelle-Zoutelande and 440,000 m3 at Breezand. Van der Lee's capability page documents an own TSHD fleet without tying a vessel or physical milestone to this contract.

Three beaches create a sequenced mobilisation

The Walcheren award is a compact but multi-location delivery programme rather than one continuous placement zone. Its three beach packages span roughly 7.05 km and require separate site logistics, survey baselines, access control and grading. Van der Lee's own TSHD fleet creates a credible self-perform route, although capability evidence does not identify the vessel or workshare selected for this contract.

Evidence conclusion

Physical start awaits project-specific evidence

TenderNed fixes the signed contractor, value, seven-bid competition and 2026-2027 delivery period. The bestek fixes the three designed quantities. No source yet connects a Van der Lee hopper dredger, borrow area, pipeline spread and survey team to one of the named beach packages, leaving mobilisation sequence and self-performed workshare open.

Outstanding evidence

  • First-site notice to proceed and mobilisation date
  • Named Van der Lee trailing suction hopper dredger
  • Borrow area, sand quality and environmental controls
  • Floating pipeline, shore pipeline and grading spread
  • Site-by-site surveys, placed quantities and acceptance
