What gbd Holding ZT does

gbd Holding ZT GmbH is an Austrian interdisciplinary engineering services group headquartered in Dornbirn and founded in 1969. The group operates through six wholly-owned subsidiaries across seven locations (with broader footprint including gbd Swiss AG), covering structural engineering (Tragwerksplanung), construction management (Baumanagement), expert opinions (Sachverständigentätigkeit), hydraulic engineering, project management, and sustainability consulting under the gbd SUSTAIN brand. Specializations span timber construction (Holzbau), clay construction (Lehmbau), concrete construction, and renovation of existing structures (Bauen im Bestand).

The firm is led by two managing partners (Geschäftsführende Gesellschafter): Dipl.-Ing. Sigurd Flora, a certified court expert and Austrian standards institute member, and Dipl.-Ing. (FH) Markus Beck M.Eng., a consulting engineer and external lecturer. In 2025 the group added Lehmit GmbH (clay/timber construction), established gbd LAB GmbH, gbd ZERT GmbH, and gbd NDT AG (laboratory, certification, non-destructive testing), launched gbd Swiss AG, and separated its internal structure into gbd Holding and gbd PTA effective September 2025.

Revenue is generated through project-based professional services contracts delivered directly to building owners, architects, municipalities, and public institutions across Austria, Germany, Italy, and Switzerland. Pricing is not publicly disclosed. The visible customer base is weighted toward Austrian municipal and state-government clients (Vorarlberg regional government, several Marktgemeinden, the City of Dornbirn, Landkreis Lindau), with limited enterprise logos in real estate, hospitality, and education. The firm has 60+ employees and reports zero external funding, no parent company, and no AI/software platform elements.

Direct peers

• Knippers Helbig Advanced Engineering: Stuttgart-based structural engineering consultancy specializing in complex geometry, timber/steel/composite structures, and parametric design. Direct peer: comparable mid-sized DACH engineering firm where bespoke structural expertise (notably in timber engineering, similar to gbd's Holzbau service line) is a core capability.
• PIRMIN JUNG Ingenieure: Swiss timber-engineering specialist headquartered in Rain, Switzerland, renowned for large-span timber structures and sustainable building physics. Direct peer: gbd's Holzbau practice, its Swiss exposure via gbd Swiss AG, and the company's project base in alpine DACH timber/clay construction align it closely with PIRMIN JUNG's profile.
• Werner Sobek: Stuttgart-headquartered engineering firm founded around the Triple Zero (zero emissions, zero waste, zero poverty) sustainability thesis, with a global practice in structures, facades, and sustainability consulting. Direct peer: same engineering-consulting DNA combined with sustainability-first positioning; similar DACH origin and multi-office model.
• Bollinger + Grohmann: Frankfurt-based structural engineering consultancy with offices across Germany, Austria, Switzerland, France, and beyond, focused on innovative, complex, and sustainable structures. Direct peer: comparable mix of Tragwerksplanung with strong sustainability/innovation positioning across the same DACH core geographies.

Broad incumbents

• ATP Architekten und Ingenieure: Austrian-headquartered integrated architecture and engineering group with offices across the DACH/CEE region, offering design and engineering services for industrial, commercial, and residential buildings. Broader incumbent: overlaps on structural and construction-management services in Austria but operates a much larger, integrated architecture+engineering portfolio rather than gbd's niche sustainability focus.
• Ramboll: Global engineering, architecture, and consulting group headquartered in Copenhagen with a significant DACH footprint and strong sustainability/ESG practice. Broader incumbent: provides overlap on structural engineering and building sustainability consulting, but at much larger scale and across many more end markets.
• Drees & Sommer: Stuttgart-headquartered real-estate and infrastructure consultancy with strong focus on sustainable, digital, and cost-efficient building lifecycle management across DACH and beyond. Broader incumbent: overlap is strongest on gbd's Baumanagement and Lebenszyklus offerings, but Drees & Sommer is significantly larger and broader in scope.
• Sweco: Stockholm-listed engineering, design, and consulting group operating across the Nordics, Netherlands, Germany, and beyond with strong sustainability services. Broader incumbent: provides overlapping structural engineering and sustainability advisory across DACH but at vastly larger scale and broader service portfolio than gbd's specialized mid-sized group.
• Buro Happold: Global engineering consultancy with European offices covering structural engineering, building services, sustainability, and project management. Broader incumbent: comparable mix of structural engineering, sustainability, and project management services but at a global scale and with much broader sector reach than gbd's specialist DACH profile.
• Arup: Global engineering consultancy operating across buildings, infrastructure, and sustainability with strong activity in Germany, Austria, and Switzerland. Broader incumbent: shares sustainability-first positioning with gbd SUSTAIN but operates at global scale with a far broader sector coverage.
