What IG BAU does

IG BAU (Industriegewerkschaft Bauen-Agrar-Umwelt) is a German trade union (Gewerkschaft) headquartered in Frankfurt am Main at Olof-Palme-Straße 35, founded in 1996 per available firmographic data and organized as a registered membership association under German law. The union represents workers across five core sectors: construction (Bauwirtschaft), agriculture and forestry (Forst und Agrar), building cleaning and facility management (Gebäudereinigung / FM/IDL), construction materials manufacturing (Baustoffindustrie), and gardening/landscaping. It structures itself across 56 Bezirksverbände (district associations) with local Mitgliederbüros (member offices) serving as primary in-person contact points.

Its core digital products are the IG BAU Mitglieder-App (available on Google Play and Apple App Store) and the password-protected Mitgliederbereich on igbau.de, which together provide members with access to collective bargaining agreements (Tarifverträge), regional office contact routing, event calendars, member data management, and digital editions of its publications Der Grundstein/Der Säemann (construction) and Forstliche Mitteilungen (forestry). The underlying technology is a conventional web-and-mobile membership platform with SEPA-based recurring payment processing; no AI/ML or third-party platform dependencies are disclosed. Sub-brands Junge BAU (youth), IG BAU Queer (LGBTQ+ network), and Frauen/Senioren structures broaden internal engagement, while campaign microsites such as the Hitzeschutz (heat protection) initiative extend its public-facing surface.

The revenue model is a single recurring subscription stream — membership dues set at 1.15% of each member's monthly gross income, collected via SEPA direct debit with monthly, quarterly, semi-annual, or annual billing options. Go-to-market is direct-to-consumer via the website's online application portal, supplemented by mobile app self-service and field recruitment through district offices. The union is governed by a Bundesvorstand (Federal Executive Board) and holds periodic Gewerkschaftstage (congresses), with the 24th Ordinary Trade Union Congress referenced on the website. It maintains an ongoing cooperation agreement with the Hans-Böckler-Stiftung for labor-law research and policy development.
