The firm provides consulting, planning, supervision, certification, and organizational fire protection services across all construction project phases, serving property owners, architects, public sector entities, corporations, project developers, and facility operators. It operates through four specialized subsidiaries: KK FIRE ENGINEERS (planning and site supervision), KK FIRE REVIEW (testing and certification by three Bavarian Prüfsachverständige), KK FIRE SERVICES (organizational fire protection, training, and external fire protection officers), and KK FIRE INSPECT (inspection of safety engineering systems such as fire alarm and voice alarm systems).

The company's core technology is specialized fire protection engineering expertise delivered by certified professionals, including expertise in engineer-based proof procedures under DIN 18009, evacuation concepts and time analysis, fire brigade plans, and escape and rescue plans. It is one of only a few engineering firms in Bavaria with three state-authorized Prüfsachverständige for fire protection, and holds additional certifications including Eisenbahn-Bundesamt recognition for railway infrastructure fire protection and authorization across multiple German states (Bavaria, NRW).

The business model is professional services fee-based, with revenue generated through project-based engagements typically procured via competitive tendering or direct referrals. Headcount is approximately 25+ employees across the parent company and subsidiaries. The firm has been involved in major Munich and Bavaria infrastructure projects including Munich Airport Terminal 1E, Munich Central Station, Deutsche Bahn projects, Ludwig-Maximilians-Universität medical complex, Roche Penzberg biotechnology facilities, Rosewood Hotel Munich, and the Deutsches Museum, where it has consulted for nearly 25 years.

Direct peers

• PLG Ingenieure: German fire-protection and building services engineering consultancy; competes for similar architect, developer, and corporate accounts with comparable service lines including fire concepts and certification.
• BFT Cognos: Specialist fire-protection engineering consultancy offering fire safety concepts, evacuation planning, and Prüfsachverständige services — directly comparable scope to KK's planning and certification subsidiaries.
• hhp Ingenieure: Hamburg-based specialist fire-protection engineering firm offering fire protection concepts, simulation, and Prüfsachverständige services across Germany; directly comparable product portfolio and target customers with national reach.
• Kempen Krause Ingenieure: Aachen-based engineering firm with a fire-protection division providing fire protection concepts, structural fire protection, and certified inspection services for complex construction projects across Germany.
• Werner Sobek: Stuttgart-based engineering firm active in structural fire protection design and engineering for complex/landmark buildings (e.g., heritage, high-rise), partially overlapping with KK's planning and structural fire-protection (DIN 18009) services.
• Halfkann + Kirchner Sachverständigenpartnerschaft: German fire-protection consulting and Prüfsachverständigen partnership; the most direct comparable given overlapping service offerings and personnel crossover (Udo Kirchner was previously a partner there; Ferdinand Wirsching joined KK from this firm).
• Sachverständigenbüro Jung: Independent German fire-protection expert office providing fire protection concepts, expert opinions, and Prüfsachverständige services; comparable niche consultancy model serving architects, developers, and public clients.

Broad incumbents

• Arcadis Germany: Global design and engineering consultancy with German fire-protection and building-safety capability; competes for large infrastructure and corporate fire-safety mandates that KK also targets (e.g., rail, airports).
• DEKRA: International testing and certification firm; broader portfolio but operates in fire-protection inspection and certification, addressing some of the same enterprise and public-sector clients as KK.
• TÜV SÜD: Global testing, inspection, and certification giant; competes in the same inspection/certification space as KK FIRE INSPECT and KK FIRE REVIEW, with much broader geographic and service scope. (KK's KK FIRE INSPECT MD Michael Ulman previously worked at TÜV SÜD.)
