What Leyrer + Graf does

Leyrer + Graf Baugesellschaft m.b.H. is an Austrian, family-owned construction group (Familienkonzern) headquartered in Gmünd, founded in 1926 and led by CEO and co-owner Stefan Graf. The company is a general contractor and vertically integrated construction group operating across seven core service areas: Hochbau (building construction), Tiefbau (civil engineering), Energie + Telekom (energy and telecom infrastructure), Asphalt, Rohstoffe (raw materials), and timber construction via its subsidiary Graf-Holztechnik. It also operates owned production assets for concrete (Graf-Beton), aggregates, and recycling, and has expanded into real estate development through Graf Development and network planning through Netz + Plan.

The business operates a project-based revenue model: it wins work through direct enterprise sales, public tenders, and established client relationships, executing multi-year contracts across public infrastructure (e.g., Wiener Linien metro), commercial real estate (e.g., Büro 21), and specialized timber projects (Europe's largest wood hotel at Vienna Airport). The company reports €635 million in annual construction output (Bauleistung), employs 2,800 people across 18 Austrian locations, and serves municipal, federal, and private-sector clients exclusively within Austria. The recently launched Graf Building Solution extends the offering into modular/system construction for affordable housing, signaling an intent to move up the value chain into standardized, repeatable productized construction.

Go-to-market is sales-led and relationship-driven, supplemented by an unusually broad owned-channel marketing mix (LinkedIn, Facebook, Instagram, TikTok, YouTube, plus press and project publications). Customer concentration appears moderate, with named anchor clients in government and large commercial real estate offset by a diversified segment mix. The competitive position rests on 100 years of brand equity, vertical integration into raw materials, scale to bid on flagship projects, and a sustainability-oriented positioning reinforced by 2024–2025 industry awards (Green Business Award, Trend Pioneer for Sustainability, Goldene Kelle).

Regional players

• Implenia AG: Swiss-based construction and real estate services company with building construction, civil engineering, and timber capabilities. Comparable services mix and timber/wood focus, but primarily serves Switzerland rather than Austria.
• Gebrüder Haider Bauunternehmen GmbH: Austrian regional construction company operating in civil engineering and building construction. Smaller competitor focused on Upper Austria, representing a regional peer face for the same Austrian tender market.

Direct peers

• Porr AG: Major Austrian construction company with comparable Hochbau, Tiefbau, and infrastructure exposure. Publicly listed competitor headquartered in Vienna, competing directly for the same Austrian and DACH-region projects.
• Swietelsky AG: Privately held Austrian construction company with similar scale (€3-4B revenue) and a comparable mix of building construction, civil engineering, and tunneling. Closest like-for-like peer in terms of ownership structure and service portfolio.
• STRABAG SE: Largest Austrian-headquartered construction group with €18B+ revenue, active across Hochbau, Tiefbau, and infrastructure across Europe. Direct competitor in the Austrian construction market and on public tenders.
• Habau Group: Austrian family-owned construction group operating in Hochbau, Tiefbau, and pipeline construction. Comparable mid-sized private competitor with overlapping geographic and service exposure.

Broad incumbents

• Bilfinger SE: European industrial services and process industry construction firm. Comparable in its energy and process infrastructure work, though predominantly serves industrial clients rather than the residential/commercial mix of Leyrer + Graf.
• Hochtief AG: German-based global construction company (subsidiary of ACS Group) with extensive infrastructure and building construction capabilities. Less direct in Austria but a relevant benchmark for scale, contracting approach, and energy/telecom infrastructure execution.
• Vinci Construction: Global construction division of Vinci group with significant European infrastructure and civil engineering exposure. Comparable in Tiefbau and large public-projects execution, though far larger and geographically diversified.

Others

• Stadtwerke Wien / Wiener Stadtwerke Group: Vienna municipal utility group that owns Wiener Linien and procures major infrastructure projects. Less a competitor and more a customer/ecosystem participant, but central to the public-infrastructure ecosystem Leyrer + Graf operates in.
