Krawinkel Engineers

What Krawinkel Engineers does

Krawinkel Ingenieure GmbH is a privately held German engineering consulting firm headquartered in Krefeld, North Rhine-Westphalia, founded in 1960 by Raimund Krawinkel. The firm provides consulting, planning, and construction supervision services for technical building equipment (Technische Gebäudeausrüstung, TGA) — covering sanitary and gas systems, heating, HVAC and ventilation, electrical systems, communications and IT infrastructure, conveying systems, usage-specific systems (medical gases, fire suppression), building and plant automation, and outdoor technical systems. Services span all HOAI Leistungsphasen, from basic concept through execution planning, tendering, and construction monitoring, delivered for both public and private sector clients across Germany and neighboring countries.

The firm employs approximately 50 qualified specialists — engineers, technicians, CAD designers, and project managers — working in age-mixed teams. Since 2019, Krawinkel has implemented integral Building Information Modeling (BIM) using Autodesk Revit as its core 3D planning platform, enabling collaborative planning and data exchange with project partners. The firm operates an independent, product-neutral planning approach and is prequalified for German public-sector procurement (PQ VOL). Notable projects include the Berufskolleg Campus Moers (NRW's largest vocational-education build), the Eisarena Bremerhaven (with heat recovery), the Win Win Towers Düsseldorf (~400 residential units), the CARL battery research lab at RWTH Aachen, and the Operatives Zentrum Klinikum Krefeld (19 operating theatres with adiabatic cooling).

Revenue is generated through project-based professional services commissions under the German HOAI fee structure for architects and engineers. The firm is privately held with no external PE/VC involvement. Ownership rests with co-Managing Directors Detlef Wingertszahn (majority since 2015) and Margret Schmidt (since 2020), alongside newly admitted authorized signatories and shareholders Maximilian Kronenberg and Stefan Kotelnicki (2025). Customers span municipalities, Kreise, universities, hospitals, sports venues, and private developers, with a strong concentration of references in NRW.
