What Geiger + Schule BAU does

Geiger + Schüle Bau GmbH & Co. KG is a privately held German Mittelstand construction company headquartered in Ulm (Ernst-Abbe-Straße 26, 89079 Ulm), operating under a GmbH & Co. KG limited partnership structure. The firm traces its roots to 1904/1923 and was restructured under its current legal form in 1990; it is led by Managing Shareholder Rolf Mezger and Managing Director Bekim Mirakaj. The company employs approximately 350 qualified personnel across the group and serves public and private-sector clients in Southern Germany as a general contractor (Generalunternehmer) or general developer (Generalübernehmer).

The company's service portfolio is organized around six core offerings — Straßenbau (road construction), Tiefbau (civil engineering), Gleisbau (railway construction), Netzbau (telecommunications network construction), Sanierung (renovation), and Planung (engineering planning) — supplemented by specialized modules including asphalt construction, site development (Erschließung), canal and pipeline construction, and in-house surveying technology (Vermessungstechnik). Equipment base includes more than 100 Liebherr machines acquired through a cooperation agreement with Nagel, plus self-operated tachymeters, GPS rovers, and digital leveling instruments for machine guidance. The firm holds ISO 9001:2015, DB Netze approvals for rail welding and stress-free temperature setting, Güteschutz Kanalbau AK1/AK2 certifications, BG Bau AMS occupational safety, and § 6a VOB-A prequalification for public procurement.

Revenue is generated through project-based construction contracts acquired via competitive bidding on public tenders and direct client relationships. Named enterprise customers include Deutsche Bahn AG, SWEG (Südwestdeutsche Landesverkehrs GmbH), Deutsche Telekom (via the BASA fiber-optic project), Teva Biotech GmbH, BSH Hausgeräte GmbH, and Merkle Eduard GmbH. The Geiger + Schüle group encompasses five affiliated entities spanning construction, project development (Geiger + Schüle Projektentwicklung GmbH), and logistics/waste disposal (Bühler Logistik + Entsorgung GmbH & Co. KG). Geographic focus is regional — concentrated in Southern Germany across Ulm, Baden-Württemberg, and adjacent Bavarian markets — with no disclosed revenue, external investors, or public market presence.
