What FELDMANN+WEYNAND does

FELDMANN+WEYNAND GmbH is a privately held German engineering consultancy headquartered in Aachen, founded around 2000 by Prof. Markus Feldmann and Dr. Klaus Weynand. Both founders are co-authors of Eurocode 3 Part 1.8 (EN 1993-1-8), the European standard for steel connection design, and the firm operates as an internationally active competence center for civil engineering, with a headcount of 11-50 employees. The company serves construction companies, engineering offices, public authorities, and industrial clients across Europe, the Middle East, and Asia, with named projects including the Elbphilharmonie Hamburg, BMW-Welt Munich, the European Central Bank in Frankfurt, Havenhuis Antwerp, and Letzigrund Stadium Zurich.

The firm operates two interlinked business lines. The first is professional engineering services covering steel construction, bridge and infrastructure engineering, facade and glass consulting, structural dynamics, building aerodynamics (including an in-house Eiffel-type boundary layer wind tunnel), and proof engineering/Prüfstatik. The second is proprietary software centered on COP (Connections of Profiles), a Windows desktop application for designing and verifying joints in steel structures according to Eurocode 3 using the component method. COP is offered in two perpetual-license editions — LITE (from €490) and PRO (from €1,480) — with optional annual update/support subscriptions at roughly 20% of license price, sold directly through a self-service web shop at cop.fw-ing.de. Differentiation rests on Eurocode authorship, integration with multi-national annexes (CEN, DE, FR, UK, AT, BE, NL), and a software development history jointly rooted at RWTH Aachen and the University of Liège.

The revenue model blends one-time software licensing, recurring support subscriptions, and bespoke engineering service contracts. Distribution is hybrid: direct e-commerce for COP software with global reach, and direct sales-led engagement for engineering services primarily in Europe, the Middle East, and select international markets. The firm maintains close strategic partnerships with RWTH Aachen, the University of Liège, KoRoH GmbH (CCTH), and other regional engineering offices, which sustain its talent pipeline, testing infrastructure access, and influence on European steel design standards.

Core offering

FELDMANN+WEYNAND provides specialized civil and structural engineering consultancy services for steel structures, bridges, facades, glass constructions, structural dynamics, and aerodynamics, supported by in-house testing facilities including a boundary layer wind tunnel and hydraulic component testing rigs. In parallel, the firm develops and sells the COP software (Connections of Profiles) for the design and verification of joints in steel structures according to Eurocode 3 (EN 1993-1-8), available in LITE and PRO editions with single-user and network licensing.

Product overview

FELDMANN+WEYNAND operates as an engineering consultancy offering both proprietary software products and professional engineering services. The core software product is COP (Connections of Profiles), a specialized Windows desktop application for designing steel structure joints to Eurocode 3, available in two editions: COP Lite (entry-level, from €490) and COP Pro (full-featured with moment connections and advanced analysis, from €1,480). COP is developed by co-authors of Eurocode 3 and is offered as a downloadable desktop application with single-user or network licensing, including update and support contracts. In parallel, the company provides comprehensive civil engineering consultancy services spanning steel structures, engineering bridges, facades and glass, structural dynamics, aerodynamics, testing, and proof engineering, supported by research and development activities.

Others

• Arup: Arup is a global engineering consultancy with a major structural steel, facade, and bridge practice. It is comparable to Feldmann + Weynand's engineering services business for signature projects, though it is much larger and operates across many more disciplines and geographies.
• RWTH Aachen – Institute of Steel Construction (Lehrstuhl für Stahlbau und Leichtmetallbau): RWTH Aachen's steel construction chair is Feldmann + Weynand's core academic partner and the institutional origin of much of its Eurocode expertise. It is not a commercial competitor but is highly relevant as the upstream research and talent source that shapes the firm's technology and credibility.
• Bollinger + Grohmann: Bollinger + Grohmann is a European structural engineering consultancy with deep expertise in steel, timber, and complex facades, frequently working on signature architecture. It is a relevant services-side peer for Feldmann + Weynand in the high-end European structural engineering market.

Direct peers

• IDEA StatiCa: IDEA StatiCa is the most direct competitor to COP, offering steel connection design software (IDEA StatiCa Connection) that targets the same Eurocode-based joint design workflow. It competes head-to-head on feature parity, BIM integration, and European structural engineer adoption.
• RISA Technologies: RISA-3D and RISA Connection are widely used structural engineering and steel connection design tools. While more US/AISC-oriented, they are a relevant peer for the steel joint design and verification use case that COP addresses.
• MIDAS IT (midas Gen / midas Steel): MIDAS provides structural analysis and steel design software (midas Gen, midas Steel) used internationally on bridge, building, and steel projects. It competes for the same structural engineering software wallet, with stronger international footprint than COP.
• SCIA Engineer (Nemetschek Group): SCIA Engineer is a structural analysis and design platform within the Nemetschek portfolio, used by European engineers for steel and composite design per Eurocodes. It competes with both Feldmann + Weynand's services and the broader CAD/CAM-adjacent position of COP.
• Dlubal Software (RFEM / RSTAB): Dlubal provides RFEM and RSTAB structural analysis software widely used by European steel engineers, including steel connection design modules. It targets the same Eurocode-driven structural engineering customer base and competes with COP in joint-design workflows.
• Trimble Tekla Structures: Tekla Structures is a leading BIM-integrated steel detailing and structural engineering platform widely used for steel connection design in Europe. It competes with COP for the same steel-construction engineer and draughtsman segment, with deeper BIM integration and a much larger commercial footprint.

Broad incumbents

• Autodesk Advance Steel: Autodesk Advance Steel is a broad structural steel detailing and connection design platform embedded in the Autodesk AEC ecosystem (Revit). It overlaps with COP on connection design but competes mainly as part of a much wider, BIM-centric workflow rather than a Eurocode-3 specialist niche.
