Jäger Bau

What Jäger Bau does

Jäger Bau GmbH is a fourth-generation, family-owned Austrian construction company founded in 1922, headquartered in Bludenz, Vorarlberg. The group operates three core divisions: Projektentwicklung (project development with in-house architecture, planning and general contractor services), Hoch- und Tiefbau (civil engineering, residential, commercial, tourism, road, water, and flood protection construction), and Untertagebau (underground construction covering hydroelectric power plants, traffic tunnels, caverns, shafts, and water tunnels). Through its Jäger-Gruppe of 15-20 companies and approximately 640-700 employees, Jäger delivers integrated construction services, in-house crafts (carpentry via Jäger Bau Tischlerei, electrical via Elektro Reisegger, sanitary via bad 2ooo), and real estate development under its own brands including AlpinLodges.

The company's core technology spans specialist tunnelling methods (drill-and-blast/Sprengvortrieb, tunnel boring machines, microtunneling), general civil engineering, and purpose-built automated logistics. Notably, Jäger achieved a world first in 1981 by successfully deploying a tunnel boring machine in demanding rock on the Walgaustollen Bürs project, and applies the Allianzmodell (alliance contracting) on landmark infrastructure projects. Its subsidiary VirtuRail develops electrically powered Automated Service Vehicles (ASV) for underground construction site logistics using sensor-based navigation without mechanical track guidance.

Jäger generates revenue through project-based general contracting for public and private clients (acquired via formal public tenders and direct enterprise relationships), real estate development and sale of its own residential, holiday, and commercial properties (Rätikon Eins, Göfis Gässele, Tschagguns Gardenga, Koblach Werben, Hard, Villingen-Schwenningen Atrium Eins), and through commercial operations of subsidiary crafts, aggregates (Transbeton/BSL), and cement logistics (STAG). Its largest single contract is the €178M ARGE partnership for the Stadttunnel Feldkirch (2025-2029). The company holds ISO 9001, Ökoprofit (21 consecutive years), and Familienfreundlicher Betrieb certifications, and is recognised as an Ausgezeichneter Lehrbetrieb for its apprenticeship programme.

Revenue model

1. Generalunternehmer (General contracting): Jäger Bau serves as general contractor for construction projects, handling project development, planning, and execution for public and private clients. Revenue is generated through fixed-price or cost-plus construction contracts across Hoch- und Tiefbau (civil engineering, residential, commercial, tourism) and Untertagebau (tunnel, shaft, cavern construction).
2. Immobilienentwicklung (Real estate development): Jäger Bau develops, builds, and sells/leases its own real estate projects (residential apartments, holiday homes, commercial spaces). Revenue is generated through property sales and rentals, with the full lifecycle from land acquisition through planning, construction, and marketing handled in-house via Jäger Immobilien GmbH / AlpinLodges.
3. Group subsidiaries and crafts: The Jäger-Gruppe includes subsidiaries providing crafts and services: bad 2ooo (bathroom/sanitary installations), Jäger Bau Tischlerei (windows, doors), Elektro Reisegger (electrical installations), VirtuRail (automated logistics vehicles), Transbeton/BSL (aggregate/quarry), STAG (cement/logistics). These generate revenue through their own commercial operations.
