Rijkswaterstaat awarded Fa. Gebr. Van der Lee contract 31205036 for three Walcheren beach-nourishment packages. The Walcheren design set calls for 550,000 m3 in situ at Westkapelse Zeedijk, 750,000 m3 between Westkapelle and Zoutelande, and 440,000 m3 at Breezand, a combined 1.74 million m3 across about 7.05 km of beach. TenderNed identifies no contract-specific vessel, site mobilisation, placed quantity or acceptance milestone.

Project anatomy

Contract scope and delivery roles

Client / authority
Rijkswaterstaat Programma's, Projecten en Onderhoud
Delivery parties
Fa. Gebr. Van der Lee - signed engineering and execution contractor, Assigned TSHD, survey team, sand source and beach pipeline spread - not identified in the reviewed official record, Lower-tier suppliers and subcontractors - no subcontracting was declared in the award notice; subsequent appointments remain unverified
Contract route
The Walcheren package went through an open European Engineering and Construct procedure under UAV 2012. Seven bids were received, including one from an SME. TenderNed records Fa. Gebr. Van der Lee as winner at EUR 8,199,000 excluding VAT and a contract signature date of 31 March 2026.
Execution window
TenderNed schedules execution from 9 April 2026 to 15 December 2027. The programme factsheet and final design allocate three Walcheren work packages. A project-specific mobilisation sequence and physical start remain absent from the official notices.
Works package
WP1 Westkapelse Zeedijk beach: 550,000 m3 in situ over about 1.5 km. WP2 Westkapelle-Zoutelande beach: 750,000 m3 over about 4.7 km. WP3 Breezand beach: 440,000 m3 over about 0.85 km. The contractor must develop execution design, mobilise marine and shore spreads, place and grade sand, survey the works and comply with environmental and safety requirements.
Marine interfaces
The three sites require offshore borrow and TSHD logistics, floating and shore pipeline configuration or alternative approved placement, beach grading, hydrographic and topographic measurement, public-access controls and coordination with exposed Walcheren coastal conditions. Separate site geometry and windows make mobilisation sequencing commercially important.
Commercial evidence boundary
EUR 8.199 million is the signed contract value. The 1.74 million m3 combined design volume provides a scope denominator, but not a valid unit-rate calculation because the public price includes engineering, mobilisation, surveys, environmental controls, pipeline operations and package-specific risk. No package prices, variations, certified quantities, payments or final account are public.
