GERSTL BAU

What GERSTL BAU does

GERSTL BAU GmbH & Co KG is a family-owned Austrian general construction contractor founded in 1921 in Wels and now led by the fourth generation of the Fehringer family through GERSTL Holding GmbH. The company operates as a Totalunternehmer (total contractor) and Generalunternehmer (general contractor) across Hoch- und Tiefbau (structural and civil engineering), serving housing associations, public institutions, commercial and industrial clients, and healthcare providers from three Austrian offices in Wels (headquarters), Vienna (regional), and Salzburg. Its 12-service portfolio spans residential housing (Wohnbauten), office buildings, hospitals and care homes, commercial and industrial buildings, schools and municipal facilities, single-family homes, renovations and conversions, structural timber construction, sewer and pipeline work, and prefabricated construction. A wholly-owned subsidiary, GERSTL Beton- und Fertigteilbau, operates an in-house precast concrete plant in Marchtrenk that supplies the core business with prefabricated elements (columns, beams, hollow-core slabs, walls, stairs), providing vertical integration on the largest material category in structural construction.

The company is the lead entity within the broader GERSTL Group, which includes ~920 employees across wholly-owned subsidiaries (GERSTL Massivhaus) and minority-held affiliates (Aichinger Bau, Glatzhofer, Hörlesberger, Norikum, Plonerbau, Steiner Bau, Weber Bau), enabling execution of multi-building projects that exceed the resource envelope of single contractors. Revenue is generated through project-based construction contracts awarded via competitive public tendering and direct negotiation with institutional clients; no standardized pricing is publicly disclosed. Named anchor projects include the €340M MedUni Campus Mariannengasse for Bundesimmobiliengesellschaft (BIG) since October 2022 and the Generalunternehmer role on ARE's VILLAGE 12B/13 in Vienna commenced May 2025. The customer base spans federal and municipal governments, non-profit housing associations (ÖSW, WIGEBA, LAWOG, GWG Linz, WSG), industrial manufacturers (Fronius, FACC), and pharmaceutical operators (Richter Pharma). Recent strategic actions include the ASTRON Buildings partnership for modular system park decks and the 2019 leadership consolidation under Markus Fehringer MBA with Reinhard Egger and Gerold Wimmer as commercial managing directors.
