Tragwerk HD Ingenieure GmbH

What Tragwerk HD Ingenieure GmbH does

Tragwerk HD Ingenieure GmbH is a Heidelberg-based structural engineering consultancy (Ingenieurbüro für Tragwerksplanung) founded in 1989 by Gerhard Brauch and rebranded to its current name in 2023. The firm is wholly owned and managed by three equal partners — Dipl.-Ing. Christian Karch, Dipl.-Ing. (FH) Ralf Edler, and Dipl.-Ing. (FH) Markus Wittmann — who assumed control through a management buyout in 2015. From its headquarters in the Heidelberg Innovation Park, the firm delivers structural planning, digital BIM-based modeling, existing building assessments, sustainable construction consulting, and on-site construction supervision for architects, developers, public institutions, and private clients.

The firm's core technical platform is BIM (Building Information Modelling) used in an IFC-compliant, model-driven workflow. Three-dimensional building and reinforcement models serve as the single source of truth from which all two-dimensional plans, reinforcement drawings, quantity and cost calculations, and collision checks are derived associatively. This methodology spans the firm's services — core Tragwerksplanung (structural engineering), Bauen im Bestand (existing building renovations), Nachhaltiges Bauen (sustainable construction), Planerstellung (drawing and documentation), and Objektüberwachung (construction supervision) — without offering them as separate modular products.

The business model is professional-services project-based work, where engagements are scoped and priced per project. The customer base spans several verticals — including the European Molecular Biology Laboratory (EMBL Imaging Centre), the Deutscher Boxsport Verband, Johann-Sebastian-Bach Gymnasium Mannheim, Gesundheitszentrum Heidelberg, and Pfeiffer & May — with no single sector dominating revenue. Distribution is purely direct, with engineering services delivered by the firm's own team of approximately 16 people in Heidelberg, serving the Rhine-Neckar metropolitan region encompassing Heidelberg, Mannheim, and Karlsruhe in Baden-Württemberg. Marketing occurs through a web-published reference portfolio and architect-led professional networks; no paid channels or reseller partnerships are used. The firm maintains educational partnerships with DHBW Mosbach and IU Internationale Hochschule to support a dual-study talent pipeline.

Core offering

Tragwerk HD Ingenieure GmbH is a structural engineering consultancy that delivers Tragwerksplanung (structural planning) for residential, commercial, industrial, and institutional buildings. Services span static calculations, execution and reinforcement plans, building physics and fire protection documentation, BIM-based 3D digital planning, existing-building renovation engineering, sustainable construction consulting, drawing production, and on-site construction supervision from concept through completion.

Product overview

Tragwerk HD Ingenieure GmbH is a structural engineering consultancy (Ingenieurbüro für Tragwerksplanung) based in Heidelberg, Germany. The company offers a unified suite of engineering services anchored by their core Tragwerksplanung (structural engineering) service, complemented by BIM-basierte Digitale Planung (digital 3D/BIM planning), Bauen im Bestand (existing building engineering), and Nachhaltiges Bauen (sustainable construction). All services are delivered through integrated digital workflows where 3D building models serve as the single source for derived 2D plans, reinforcement drawings, and quantity calculations. The portfolio is organized as a single integrated service offering rather than discrete software products or modules.

Functional benefit

Products and services

• Tragwerksplanung (Structural Engineering / Planning) Core structural engineering service covering static calculations, execution plans, structural integrity certifications, fire protection documentation, and building physics considerations for new builds and existing structures across residential, commercial, industrial, and civil engineering sectors. Target clients include property developers, architects, public institutions, and private homeowners.
• BIM – Digitale Planung (Building Information Modelling) Digital 3D planning methodology using IFC-compliant standards, creating associative 3D building models that serve as the basis for all 2D plans, reinforcement plans, collision checks, and quantity/cost calculations throughout all project phases. Delivered to clients as a planning service, not as a standalone software product.
• Bauen im Bestand (Construction in Existing Buildings) Specialized structural engineering service for analyzing, evaluating, and engineering modifications to existing buildings. Includes existing building surveys, structural capacity assessments, renovation and strengthening recommendations, and fire protection certifications for historic and listed structures. Targeted at property owners, municipalities, and developers undertaking conversions including former military sites.
• Nachhaltiges Bauen (Sustainable Construction Consulting) Sustainable building consulting focusing on conscious use of new and recyclable resources, minimization of energy consumption, avoidance of long transport routes, and use of renewable, biodegradable, regional, durable, and recyclable materials, with lifecycle assessment considerations.
• Planerstellung (Drawing and Documentation Services) Professional creation of all plan types including reinforcement plans, design plans, demolition plans, formwork plans, as-built plans, position plans, and construction plans, all derivatively generated from 3D building models for each project phase.
• Objektüberwachung (Construction Supervision) On-site supervision and monitoring during construction execution, ensuring structural works comply with the engineering plans, specifications, and approvals.
