What De Boer & De Groot does
De Boer & De Groot civiele werken b.v. is a Dutch civil engineering contractor headquartered in Harlingen, Friesland, founded in 1997 and operating with 51-100 employees across five northern Dutch provinces. The firm specializes in concrete and water construction (beton- en waterbouw), restoration of monumental water structures, and concrete technology (betontechniek), executing projects at the land-water interface such as bridges, quays, harbor works, sluice gates, and flood-protection infrastructure for government and municipal clients. Service delivery spans design through execution, supported by an in-house developed CE-certified lifting capability and a deep certification stack that includes ISO 9001, NEN-EN 1090, BRL 3201, VCA**, and the CO2 Performance Ladder at Level 5.
The company's revenue model is B2B project contracting acquired through tenders and direct engagement with Dutch public-sector clients. Beyond bespoke project work, De Boer & De Groot commercializes JETTY, a modular sustainable pier system, signaling a shift toward standardized product offerings. In 2025 the firm was acquired by Ploegam and Dura Vermeer alongside ADONIN, integrating it into two established Dutch construction groups and providing access to broader infrastructure programs including the Dijkzone Alliantie Zwolle dike-safety alliance. A partnership with Scheepsbouwbedrijf Groeneveldt and Ploegam has placed an order for three fully electric work vessels for Q4 2026 delivery, formalizing an emission-free operating platform. The firm markets primarily through its website, supplemented by regional industry press such as Ondernemend Friesland.
