What pin does

PIN Planende Ingenieure GmbH is a Berlin-based, privately held German engineering consultancy founded in 1983 that specializes in technical building equipment (Technische Gebäudeausrüstung, TGA) planning. The firm delivers the full HOAI §73 Leistungsphasen 1-9 service spectrum across six core disciplines — sanitary systems, heating, ventilation, cooling, high-voltage electrical, and telecommunications/IT infrastructure — for both new construction and renovation projects. It is operated by a 30-person team of engineers and planners out of a single Berlin office at Reichsstraße 4, with managing directors Tim Müller (also shareholder) and Norbert Müller.

The firm sells project-based professional services directly to building owners (Bauherren), developers, architects, and public institutions. Its revenue is generated per project via HOAI-regulated fee structures tied to TGA construction cost, with disclosed sample project TGA scopes ranging from roughly €0.6M (Max Planck lab) to €48M (Quartier am Tacheles, 127,000 m²). The customer base spans government/embassy (U.S. Embassy Berlin, Bundesamt für Bauwesen), healthcare (St. Joseph Krankenhaus), hospitality (Hotel Adlon, Grand Hotel Heiligendamm), education (Humboldt-Universität), automotive (BMW), and research (Max Planck) segments. BIM coordination has been added to the offering alongside traditional CAD-led planning. There are no disclosed revenue figures, no external investors, and no digital marketing or channel partnerships; growth has been reputation- and referral-driven over a 40-year operating history with 800+ completed projects.
