Haarsma Groep

What Haarsma Groep does

Haarsma Groep is a privately held, family-owned Dutch civil engineering and construction company headquartered in Tjerkwerd, Friesland, founded on October 1, 1975 by Ule and Hiltje Haarsma. The company operates as an integrated multi-discipline contractor organized into six operational divisions: Infra & Milieu (ground, road, water and civil concrete construction), WegenBouw Recycling (WBR), Transport, Kraanverhuur (crane rental), Projectontwikkeling (project development), and Gladheidsbestrijding (winter road maintenance). With approximately 90 employees and four operating sites in Tjerkwerd, Franeker, Wieringerwerf, and Sneek, Haarsma delivers project-based civil works including roundabouts, sewer reconstruction, residential district preparation, marinas, dike reinforcement, and energy-transition cable-laying across North Holland and Friesland.

Underlying technology centers on a modern, GPS/3D-equipped fleet (Leica 3D GPS excavators, an electric SANY 215E crawler for nitrogen-sensitive zones, Develon DX140W-7 graders, and 8x8 off-road trucks) coupled with in-house material recycling that closes a circular loop between construction waste generation and aggregate supply. The WBR division processes concrete rubble, asphalt, and green waste into menggranulaat, sand, certified compost, and other road-building inputs, supported by a loading quay (loswal) at Franeker enabling inland waterway shipment and a direct-to-customer webshop. The company holds ISO 9001, CO2 Prestatieladder, VCA, BRL, and KAM certifications, and is a founding member of the Betonketen Fryslan consortium working to decarbonize concrete in the region.

The business model is overwhelmingly project-based and B2B/B2G, with revenue generated from one-off public tenders (municipalities such as Den Helder, Hoorn, Heerhugowaard, Langedijk, Stede Broec, Waadhoeke; Province of Friesland) and negotiated private contracts (subcontracting for BAM Infra, KWS, and Boskalis). Additional recurring streams come from transaction-based sale of recycled aggregates via WBR, crane and equipment rental, bulk/low-loader transport, and recurring winter maintenance contracts. Pricing is not publicly disclosed; multi-year contracting and tender-driven quote-based pricing dominate, and the firm is family-managed with Tjeerd Haarsma serving as Directeur and no external investors or funding rounds on record.

Core offering

Haarsma Groep is a family-owned Dutch civil engineering and infrastructure group delivering civil infrastructure construction (Infra & Milieu), construction and demolition waste recycling (WBR), heavy transport, mobile crane rental (Kraanverhuur), project development (Projectontwikkeling), and winter road maintenance (Gladheidsbestrijding). The company sells these as contracted services — not physical products — to municipalities, provincial authorities, developers, contractors, and industrial clients primarily in the North Holland and Friesland regions of the Netherlands.

Product overview

Haarsma Groep is a multi-disciplinary civil engineering and construction company organized as a unified group of divisions rather than a platform-plus-modules structure. The core offering centers on Infra & Milieu, which delivers integrated ground, road, water, and concrete construction services for projects ranging from roundabouts and bicycle tunnels to complete residential district development. Supporting this core are specialized divisions: Wegen Bouw Recycling (WBR) handles construction waste recycling at Franeker and Sneek locations, producing construction materials like menggranulaat, sand, and compost; Transport operates a modern truck fleet for materials logistics; Kraanverhuur provides crane and excavator rental; Projectontwikkeling develops commercial sites, marinas, and residential areas; and Gladheidsbestrijding offers winter road maintenance. The company also maintains a WBR Webshop for online ordering of recycled construction materials.
