Kleywegen B.V.

What Kleywegen B.V. does

Kleywegen B.V. is a Dutch civil engineering contractor headquartered in Woerden, Utrecht, founded circa 1998 and operating under director Jelle van der Kleij. The firm specializes in grond-, weg- en waterbouw (GWW) — ground, road, and water construction — serving waterschappen (water boards), gemeenten (municipalities), construction companies, and project developers across the Netherlands. Its named client roster spans large construction primes (Cordeel Nederland, Dura Vermeer, Ballast Nedam, Jan Snel, Heddes Bouw & Ontwikkeling, Batenburg Bouw en Ontwikkeling), water authorities and municipalities (Waternet, Gemeente Gouda, Gemeente Lansingerland), and developers/transit operators (Amvest, AM, Arriva).

The company's service portfolio is anchored in risk-bearing soil remediation (risicodragende bodemsanering), a differentiated line of work in which Kleywegen assumes contamination liability that most GWW competitors decline. Adjacent service lines include custom construction pits (Bouwkuip op Maat), bridges via the KleyBruggen sub-brand, and rooftop and structural gardens via Kleydaktuinen/Kleytuinen. Operational technology includes GPS-controlled excavation with 3D machine control for precision earthworks. The firm holds VCA**, ISO 9001:2015, BRL 7000/7005/7007 (soil remediation protocol), CO2 Prestatieladder Trede 5, SCL Light Trede 3, and BRL 3000-ERB certifications, which collectively gate access to Dutch public-sector tender pipelines.

Kleywegen operates a project-based contracting model, tendering directly for civil works from public bodies and acting as subcontractor for larger construction primes. The company has been a portfolio entity of the Valutum group since 2016; Valutum holds approximately ten Dutch SMB companies totaling roughly 350 employees. With approximately 40 employees, Kleywegen is positioned as a specialized mid-market regional contractor rather than a national prime, and the firm's growth path to date has been driven by service-line extension within the Dutch GWW market rather than geographic or scale expansion.

Broad incumbents

• Koninklijke Boskalis Westminster N.V. Global Dutch dredging and marine contractor with significant Dutch civil engineering and environmental remediation activities. Comparable on the environmental/civil engineering overlap, though operating at vastly larger scale and with a maritime focus.
• Koninklijke BAM Groep: Major Dutch construction and civil engineering group with national reach across infrastructure, public-private partnerships, and property. Competes with Kleywegen in Dutch tendered GWW work (roads, bridges, water) and is a typical benchmark competitor for Dutch public tenders.
• VolkerWessels: Large Dutch construction and infrastructure group with Dutch and international operations in civil engineering, housing, and energy infrastructure. Comparable as a competing bidder for the same Dutch municipal and waterschap infrastructure projects.
• Heijmans N.V. Largest Dutch-listed construction and civil engineering company operating across infrastructure, residential, and non-residential markets. Comparable as a Dutch GWW contractor serving municipalities, waterschappen, and developers with overlapping capabilities in road, water, and earthworks, though at vastly larger national scale.
• Dura Vermeer Infra B.V. Major Dutch construction and infrastructure firm. Listed as a Kleywegen customer (OKU House Amsterdam) but also a broad incumbent bidder for the same Dutch tendered GWW work. Comparable Dutch infrastructure competitor.
