INTRAKON GmbH

What INTRAKON GmbH does

INTRAKON GmbH is a private German engineering firm headquartered in Recklinghausen, North Rhine-Westphalia, with a second office in Münster operated through its wholly-owned subsidiary Otten Beratende Ingenieure GmbH. The firm provides structural engineering (Tragwerksplanung), construction design, and building physics services for reinforced concrete, steel, timber, and hybrid buildings across all HOAI service phases. Its customer base consists of architects, real estate developers, property owners, healthcare facility operators, and public/institutional clients such as Flughafen Düsseldorf, with projects spanning residential, commercial, healthcare, and aviation segments. Notable projects include timber parking structures in Rüsselsheim designed with KG5 Düsseldorf and 89-bed care facilities in Herne and Bochum.

The firm's service portfolio integrates BIM-based 3D planning using Allplan 3D (added in 2016), BOCAD 3D for steel workshop drawings, building-physics certifications (sound and thermal insulation), BAFA-funded energy consulting, and sustainability-certification services including DGNB audits and QNG certification support. Sustainable structural engineering incorporating Life Cycle Assessment (LCA) and plus-energy building design — exemplified by INTRAKON's own self-designed plus-energy headquarters completed in 2013 — is the firm's primary technical differentiator.

Revenue is generated through project-based professional services fees under the HOAI (Honorarordnung für Architekten und Ingenieure) fee structure. The company operates a sales-led GTM targeting enterprise clients via direct relationships, professional networks, referrals, and its own website plus LinkedIn/Facebook/Instagram channels. INTRAKON is family-run, privately held, and has not raised external funding; management consists of Geschäftsführer Jörg Friemel (founder, qualified structural planner and energy consultant), Geschäftsführer Marco Kolloczek (DGNB Auditor since 2023), and Prokurist Marcel Schäfers (qualified structural planner).
