IBK Engineering Office Kohn

What IBK Engineering Office Kohn does

IBK Engineering Office Kohn (legal name Ingenieurbüro Kohn GmbH & Co. KG) is a privately held German engineering services firm founded in 1970 in Barmstedt, part of the Hamburg metropolitan region. The firm specializes in technical building equipment (Technische Gebäudeausrüstung, or TGA) planning, covering heating, ventilation and air conditioning, sanitation, electrical engineering, conveyor systems, kitchen technology, technical/medical gases, and building automation. It delivers its services across all nine HOAI (Honorarordnung für Architekten und Ingenieure) performance phases, from initial requirements analysis and conceptual design through detailed execution planning, tendering, construction supervision, and final documentation, providing clients with an integrated single-source planning solution.

The firm's technology stack is centered on CAD-based technical system planning, including 3D modeling for building services, combined with standard modern planning tools. Its service portfolio emphasizes holistic, coordinated planning — combining supply engineering (Heizung, Lüftung, Sanitär) with electrical engineering within a single engagement to reduce interface risk on construction projects. There is no indication of proprietary software products, AI/ML capabilities, or platform-based delivery; the offering is purely a professional services practice.

Commercially, IBK operates on a project-based, quote-based fee model tied to HOAI service phases, generating revenue through professional services engagements with construction and building-project clients across Hamburg and northern Germany. The firm employs approximately 20 people and is owned and led by the founding Kohn family, with Philipp and Henrik Kohn and Jens Hansen serving as managing directors following a 2024 generational succession from Kai Kohn. Customer-facing channels are limited to a direct project inquiry form on the company website, reflecting a sales-led, relationship-driven GTM motion concentrated in its regional market.

Direct peers

• ZWP Ingenieur-AG: German MEP engineering firm specializing in technical building equipment planning (Heizung, Lüftung, Sanitär, Elektro) across HOAI phases. Closest functional peer to IBK in scope of services and delivery model.
• Ingenieurgruppe Bauen: Mid-sized German engineering consultancy providing integrated building services and structural engineering planning. Directly comparable to IBK in offering integrated TGA + electrical planning for building projects.
• GA-tec Gebäude- und Anlagentechnik GmbH: German building services engineering and technical facility management provider covering heating, ventilation, air conditioning, sanitation, and electrical systems. Comparable as a German MEP/TGA peer, though broader into installation and FM.

Broad incumbents

• Sweco GmbH (Germany): European engineering consultancy with a German office covering buildings, infrastructure, water, and energy — including MEP/TGA planning. Comparable as a broader incumbent offering overlapping building services capabilities.
• Drees & Sommer: Large German engineering consultancy offering integrated building services, MEP planning, energy and sustainability consulting across all HOAI phases. Comparable as the scaled, broad-incumbent version of IBK's TGA + electrical planning model.
• Ramboll Germany: International engineering consultancy with German operations delivering building services design, energy consulting, and sustainability across HOAI phases. Comparable as a large, multi-disciplinary incumbent operating in IBK's category at greater scale.

Others

• HPP Architekten: Major German architecture practice that coordinates MEP/TGA consultants on integrated building projects. Comparable as a downstream counterpart that frequently engages the same TGA planning scope IBK delivers, particularly on commercial and cultural projects.
