What H4A does
H4A (legal name Holding De Vier Ambachten bv, founded 1968 in Sas van Gent, Netherlands, with predecessor De Ruijsscher & Zn dating to 1920) is a privately held, family-controlled multi-disciplinary construction and infrastructure contractor employing approximately 340 people across Zeeland, the rest of the Netherlands, Belgium (Flanders and Wallonia), and Luxembourg. The group operates through five core expertise divisions — Bouw (construction), Industrie Service (industrial civil and maintenance), Openbare Ruimte (public infrastructure, roads, greenery, road markings), Ondergrondse Netwerken (electricity, gas, water, and telecom underground networks), and Windenergie (civil Balance-of-Plant for onshore wind) — supplemented by subsidiaries Mobach Transport & Verhuur (bulk and asphalt transport, acquired 2017) and W.J. de Bruijn (road markings, acquired 2007), plus the support services Omgevingsmanagement and Projectontwikkeling.
The technology base is conventional civil engineering and construction services — foundation work, asphalt road construction, wind turbine foundation Design & Build with access roads and crane platforms, and certified cable/pipeline installation — combined with an unusually deep stack of credentials (CO2 Prestatieladder Niveau 5, ISO 9001, VCA**, VCA Petrochemie, Safety Culture Ladder Trede 2 and 3, CKB, BRL SIKB 7000, BRL 9142, ErBo, GMP+ FSA) that function as prequalification gates for petrochemical, grid-operator, and large wind-developer tenders. Customer mix spans long-running industrial maintenance accounts (Dow Benelux since 2007, Cargill, Yara, ICL-IP), grid operators (Stedin/DNWG), wind developers (Eneco, Luminus, Elicio, Engie, Aspiravi, Zeeuwind, Lindewind, Hegoa Wind SA, Green Trust Projects, Coöperatie Bommelerwaar, LCL Energy), municipalities (Gemeente Hulst, Gemeente Goes), and housing/property developers (Woongoed Zeeuws-Vlaanderen, AM Zeeland).
The business model is project-based B2B contracting: revenue is generated through tenders, direct quotes, and long-term maintenance agreements, with pricing opaque and bespoke per project. GTM is sales-led, executed through account management for industrial clients and direct project sales for government and developer clients across regional and (for wind) Benelux-wide geographies. Notable current and recent projects include the Windpark Ze-Bra repowering (15 turbines in Rilland for Eneco/Zeeuwind/Lindewind), Project Mufasa battery park civil works in Vlissingen-Oost (~1,400 MWh / 350 MW with SPIE Nederland), and the Aers Truckplaza future-mobility hub in Zeebrugge (~50,000 m2). The firm is led by new general director Leonard Pekaar following the March 2026 retirement of founding family principal Eric de Ruijsscher.
