Kurz und Fischer

What Kurz und Fischer does

Kurz und Fischer GmbH Beratende Ingenieure Bauphysik is a privately held German consulting engineering firm specializing in building physics (Bauphysik), founded in 1988 in Winnenden by Roland Kurz and Erik Fischer. The firm delivers professional engineering services across the full HOAI performance phase spectrum — from planning through construction supervision — covering building acoustics, room acoustics, sound immission control, vibration and shock control, thermal building physics, protection of constructions, sustainability consulting (including DGNB auditing and life cycle assessment), radon protection, and the in-house design and construction of specialized measuring equipment (the Gösele system small hammer mill and pressure chambers). It holds rare regulatory credentials including DIN EN ISO/IEC 17025:2018 testing laboratory accreditation, § 29b BImSchG notification for airtightness measurement, VMPA Test Center status, and publicly appointed and sworn expert designations.

The firm serves architects and planners, building owners and developers, public sector clients, and courts/legal entities across Germany, primarily through direct project-based consulting engagements. Its customer base spans healthcare facilities (Klinikum Rechts der Isar, Herzzentrum München), municipal authorities (Stadt München, Staatliches Bauamt München 1), educational buildings, residential real estate developers (PANDION AG, Reiß & Co.), and corporate construction projects. Marketing reach is driven through professional publications, university research cooperation, and active memberships in DEGA, DGNB, VDI, and VMPA rather than traditional demand-generation channels.

The company operates five owned branch offices (Winnenden HQ, Halle/Saale, Feldkirchen-Westerham, Bottrop, Bretten) and is connected to two adjacent operating entities — STEP (Schalltechnisches Entwicklungs- und Prüfinstitut GmbH) in Winnenden for sound engineering development and testing, and BIMphysics Kft. in Budapest for building physics and acoustic modeling — plus the ALN partner office network covering Lübeck/Kiel/Schwerin in northern Germany. Revenue is generated through professional services on a project-based fee structure under HOAI; specific rates are not publicly disclosed and no revenue figures are reported.
