Maassluis M2 quay-wall replacement and waterfront renewal

Official Maassluis Haven M2 quay wall construction phases showing the retaining wall and raking piles in the staged replacement sequence

Gemeente Maassluis / Ingenieursbureau Maters en De Koning; exact official construction-phase drawing, not current progress or as-built evidence

Gemeente Maassluis has awarded De Vries Werkendam B.V. a EUR 7,887,000 contract to replace approximately 210 m of quay wall on the east side of the Haven and reconfigure approximately 3,000 m2 of public space. TED records contract conclusion on 4 August 2026. The municipality's project page, last modified the same day, says physical work is planned for 5 October 2026 to 21 July 2028. That owner programme differs from the TED procurement periods and no cited source yet proves site possession, first waterside operation or installed work.

Project anatomy

Contract scope and delivery roles

Client / authority
Gemeente Maassluis
Delivery parties
De Vries Werkendam B.V. - confirmed main contractor under TED notice 542353-2026, Sheet-pile, piling, demolition, temporary-works, public-realm, survey and utility lower tiers - no organization disclosed
Contract route
Gemeente Maassluis used an EU open works procedure under TED procedure 3618cf23-2ac0-42bb-bbe1-90567d6ff804. Tender notice 107393-2026 was published on 16 February 2026. Award notice 542353-2026, published on 5 August, identifies De Vries Werkendam B.V. as the single winner, records contract conclusion on 4 August and states that no subcontracting is reported.
Execution window
The original tender notice planned 7 July 2026 to 24 December 2027, and the award notice carries 3 August 2026 to 24 December 2027. The municipal page instead plans physical delivery from 5 October 2026 to 21 July 2028. These scheduling fields do not establish site possession, mobilisation, first physical work, completion or acceptance; an accepted contract programme must reconcile them.
Works package
The works replace approximately 210 m of the M2 quay wall on the east side of the Haven and renew approximately 3,000 m2 of adjoining public space. The owner says the 1935 structure has a poor foundation and is rotating toward the water. Its official phase drawing shows staged demolition, temporary support, new retaining-wall installation, raking piles, a structural floor, anchors, quay wall and furniture; the public-space plan shows the linear waterfront arrangement. These drawings define intended scope, not completed quantities.
Marine interfaces
Delivery must maintain stability along an ageing inner-harbour edge while existing elements are removed and a new retaining and piled structure is formed. Critical interfaces include the temporary October 2024 stabilisation, retained foundations, demolition sequence, water-side access, sheet-pile and raking-pile installation, anchors, structural slab, utilities, adjacent properties, traffic and public-space reinstatement. Marine plant, issued-for-construction quantities, utility diversions and navigation controls remain undisclosed.
Commercial evidence boundary
TED records EUR 7,887,000 as the contract result and identifies De Vries Werkendam as a medium-sized enterprise. No cited record establishes a final account, payment status, variations, contingency allocation, lower-tier values or savings. The value should not be combined with unverified programme or municipal budget figures.
