What De Vries Werkendam does
De Vries Werkendam B.V. is a Dutch family-owned civil engineering and water construction contractor founded in 1963 and headquartered in Werkendam, Netherlands. The company operates three wholly-owned divisions under one roof — De Vries Beton- en Waterbouw (concrete and hydraulic engineering for quay walls, bridges, locks and bank structures), De Vries Titan (anchoring, foundation piles, and geotechnical engineering including self-drilling grout anchors and live anchor-force monitoring), and De Vries Vsp/Tensa (post-tensioning and cable-stay prestressing systems, acquired from Strukton in March 2022). Core technical capabilities span in-house design, NEN-EN 1090-certified steel manufacturing up to execution class 3, and specialized equipment including the hybrid hydrogen-electric 'Ruigt' workship commissioned in December 2022 for emission-free operations.
The firm serves government agencies (Rijkswaterstaat, provinces, municipalities, water boards such as Waternet and Waterschap Amstel Gooi en Vecht), construction prime contractors (ProRail, THV Rinkonien, Sagro, Mobilis-Van Gelder), and industrial clients across the Benelux. Projects are won predominantly through competitive public tendering under UAV-2012, RAW 2012, and UAV/gc contract frameworks, with disclosed individual contract values ranging from approximately EUR 1.25 million to EUR 4 million.
Revenue is generated through project-based professional services contracts for new construction, maintenance, renovation, and restoration of waterway and civil infrastructure, with pricing determined per project. The company maintains approximately 90 fixed employees, holds a comprehensive certification stack (Safety Culture Ladder Level 4, VCA**, ISO 9001, ISO 14001, CO2 Performance Ladder Level 5, FSC, Green Award Gold), and leverages technology licensing partnerships with Tensacciai S.r.l. (since 2002) and BBR VT International LTD (since April 2024) to access specialized prestressing and cable-stay systems.
