Kostmann

What Kostmann does

Kostmann GesmbH is a family-owned, vertically integrated Austrian construction, raw materials, and transport group headquartered in St. Andrä im Lavanttal, Carinthia, with approximately 600 employees as of November 2024 and additional offices in Villach, Klagenfurt, and Kainach bei Wildon. The company operates across the full construction value chain — owning and operating quarries (Fellach, Föderlach, Hart), asphalt and concrete mixing plants, a fleet of more than 160 trucks, in-house quality control laboratories, electrical and vehicle workshops, and BIM-enabled planning services — and executes residential, commercial, industrial, civil engineering, road, bridge, and infrastructure projects for public and private clients across Austria. Revenue is generated through four streams: project-based construction services under fixed-price or cost-plus contracts; raw material extraction and sales of aggregates to external customers; asphalt and concrete production sold to construction projects; and national and international transport services covering silo, tank, tipper, flatbed, and special heavy loads. Go-to-market is sales-led and tender-driven, with active participation in public procurement for government and municipal infrastructure alongside direct engagement with industrial and commercial clients.
