Schluter + Thomsen Ingenieure Gmbh

What Schluter + Thomsen Ingenieure Gmbh does

Schluter + Thomsen Ingenieure GmbH is a privately held, owner-managed German engineering consultancy headquartered in Neumünster, founded circa 1976, that delivers integrated building services, electrical, and fire protection engineering. The firm operates four core service lines under one roof — Brandschutzplanung (fire protection planning), Elektroplanung (electrical engineering), TGA-Fachplanung (technical building equipment), and a specialized Heissbemessung (Eurocode-based fire resistance structural analysis) — covering all HOAI performance phases 1–8. This combination of electrical and fire protection planning from a single office is positioned as unique in the northern German market.

The firm's technology foundation is BIM-based 3D and CAD planning using DDS-CAD, DIALux, and AutoCAD, with Eurocode-based numerical and analytical methods for fire structural analysis, and a partnership with imagine digit for the resqmatic dynamic escape route management system. The firm also supports DGNB, LEED, and BREEAM sustainability certification as part of integrated planning. Across nearly 50 years of operation and 4,000+ realized projects, S+T serves enterprise, government, and nonprofit clients across nine vertical segments — sports venues (KSV Holstein, HSV, VfL Osnabrück, THW Kiel venues), commercial real estate (Justus Grosse, CITTI, Holstenhallen), healthcare (DRV Nord), pharma/industrial (Ferring GmbH, LESER), education, culture (Europäisches Hansemuseum), and public sector (Stadt Neumünster, Berlin) — through project-based professional services fees across 5 German locations (Neumünster HQ, Hamburg, Kiel, Stuttgart, Sylt). Sponsorship partnerships with KSV Holstein, Hamburger SV, THW Kiel, and KTV Adler anchor its sports venue positioning.

Revenue is generated through professional services fees for consultancy, design, construction supervision, and technical due diligence, billed on a project basis with no public pricing disclosure. Go-to-market is direct sales-led, engaging project developers, architects, general contractors, and public authorities through professional networks, referrals, industry events (Light & Building, Feuer Trutz), and the firm's own content marketing and sports sponsorship channels. The legal structure comprises SCHLÜTER + THOMSEN Ingenieurgesellschaft mbH & Co. KG (operating entity), SCHLÜTER + THOMSEN Brandschutz GmbH & Co. KG (fire protection subsidiary), and related Verwaltungs-GmbH entities, all registered in Neumünster with managing directors Sönke Reimers, Silke Hinrichsen, and Devrim Yilmaz. No external institutional investment or PE/VC backing is indicated.

Expansion highlights5 records

Broad incumbents

• ZWP Ingenieur-AG: Cologne-based engineering firm offering TGA planning, structural engineering, and building services design across Germany. Overlaps with S+T's TGA-Fachplanung and Elektroplanung services at a larger scale, serving many of the same commercial real estate and public-sector clients.
• Kempen Krause Ingenieure: Larger German engineering consultancy with broad TGA, structural, and fire protection planning services across multiple German offices. Comparable offering to S+T but with substantially greater headcount and national footprint, making it both a peer and an incumbent competitor for larger mandates.
• EGS-plan Ingenieure: German engineering consultancy focused on energy, building services, and solar/renewable systems planning. Comparable to S+T's TGA-Fachplanung offering, with particular overlap in energy-efficient and sustainable building design — including support for sustainability certifications.
• Drees & Sommer: One of Germany's largest engineering consultancies, with comprehensive TGA, sustainability, and project management services including DGNB/LEED/BREEAM support. Directly overlaps with S+T's integrated planning and sustainability certification offering, but operates at substantially greater scale with national and international reach.

Direct peers

• Planungsgruppe M+M AG: German engineering consultancy delivering integrated TGA, electrical, and fire protection planning across multiple offices. Closely comparable to S+T in service mix and integrated one-roof positioning, with somewhat broader geographic coverage.
• BRENDEL INGENIEURE: German engineering consultancy offering fire protection, structural, and technical building equipment planning. Comparable to S+T in combining Brandschutz and TGA planning from a single German office, with similar mid-sized, owner-managed characteristics.
• hhpberlin: Berlin-based engineering consultancy specializing in fire protection and structural fire engineering (Brandschutz), with national reach. Directly comparable to S+T's fire protection planning offering; notably, S+T's Hamburg branch lead Devrim Yilmaz previously worked at hhpberlin, indicating close technical and cultural overlap.
• JBP Planungsgesellschaft mbH: Mid-sized German engineering firm offering TGA and electrical planning services. Comparable to S+T in scope and structure, serving commercial real estate and public-sector clients with integrated technical building equipment planning.
• Schneider Brandschutz: Specialized German fire protection planning consultancy. Comparable to S+T's Brandschutzplanung offering, particularly in code compliance, escape route planning, and fire safety certificates — though narrower in that Schneider focuses primarily on fire protection rather than the integrated electrical + TGA scope S+T delivers.

Emerging players

• BOLINGER + GROHMANN: German engineering firm with strength in structural and building services engineering, particularly on complex architectural projects. Overlaps with S+T on the engineering consulting side of technically demanding building projects, though B+G focuses more on structural engineering than fire protection.
