What LEONHARD WEISS does

LEONHARD WEISS is a fourth-generation, family-owned German construction company headquartered in Satteldorf with an additional founding-site office in Göppingen. Founded in 1900 as a railway track construction specialist, it has grown into a full-service infrastructure provider delivering railway construction, track-laying machinery services, road and underground engineering, civil and structural engineering, turnkey building, facility management, overhead line construction, network construction, timber hybrid construction, and raw materials production through ten wholly owned subsidiaries (AMG Asphaltmischwerk, FOCUS RAIL Engineering, infra-tec, invatec, Rose Kabelmontage, SDC, VIA Verkehrssicherung, IHM, and others).

The company operates an enterprise field-sales go-to-market, bidding on large public-sector and regulated infrastructure contracts (notably with DB Netz AG, the City of Munich, and the Frankfurt municipal authority) and joining ARGE working-group joint ventures for mega-projects such as the Riedbahn general renovation and Stuttgart 21. Revenue is generated primarily through project-based construction contracts with multi-year durations, complemented by a recurring facility management services stream and specialized subsidiary offerings in asphalt, noise protection, cable infrastructure, flooring, and traffic safety. Building Information Modeling is deployed as the digital backbone for planning, execution, and facility management, with newer AI applications limited to drone-based site documentation and the LW.Kraftwerk energy-load optimization program.

LEONHARD WEISS reports revenue of over EUR 2 billion (up from approximately EUR 300 million in 1998, implying a doubling cadence every ten years) and employs more than 7,500 people. It is ISO 45001 certified, has been a Focus Business Top Employer in the construction industry since 2013, and operates internationally with projects in Poland, Romania, Sweden, Estonia, and historically Egypt.
