The signed Ringvaart 2 contract gives Van der Lee an estimated 108,000 cubic metres of canal material to manage across two distinct routes: about 86,500 cubic metres to an approved processor and 21,500 cubic metres to a local grassland depot.

Signed scope leaves execution evidence open

TenderNed controls the signed award, value, procedure, duration and estimated sediment-routing quantities. The announcement and dataset anchor the official record. Van der Lee's capability page supports general contractor context only and does not identify project plant or progress.

Material routing drives the delivery chain

Roughly four-fifths of the estimated volume is classified for off-site processing rather than local placement. That makes processor access, transport capacity, classification evidence and acceptance records central to schedule and cost, even though TenderNed's award disclosure states no subcontracting and names only the prime contractor.

Evidence conclusion

Separate the two sediment routes from physical progress

TenderNed confirms the EUR 4,087,280.31 signed award, five-bid competition, 23-month estimate, canal sections and the 86,500 / 21,500 cubic-metre routing split. The public record leaves assigned plant, the approved processor, grassland depot, haul route, survey baseline, measured quantities, accepted loads, completion and final account open. The no-subcontracting field is a procurement disclosure, not proof that no later suppliers or service providers will participate.

Outstanding evidence

  • Notice to proceed and mobilisation
  • Dredging and loading method
  • Approved processor identity and capacity
  • Grassland-depot identity and acceptance
  • Sediment classification and chain-of-custody records
  • Measured quantities and variations
  • Completion certificate and final account
