GESA Ingenieurgesellschaft für Technische Gesamtplanung

What GESA Ingenieurgesellschaft für Technische Gesamtplanung does

GESA – Ingenieurgesellschaft für Technische Gesamtplanung mbH is a privately held German engineering services firm founded in 1992 and headquartered in Dresden, with two additional offices in Hamburg (Pinneberg) and Cologne. The firm specializes in comprehensive planning of technical building equipment (TGA — Technische Gebäudeausrüstung), delivering full-scope engineering services according to HOAI performance phases 1–9, including expert studies, concept development, detailed design, construction supervision, and project management. Its portfolio spans nine service lines: energy generation and distribution; ventilation, air-conditioning and refrigeration; heating and sanitary technology; electrical engineering and data networks; automation technology and monitoring; facility management; GMP/FDA qualification; pure-media and technical gas systems; and pharmaceutical technology.

The firm's technical stack relies on industry-standard 3D CAD and BIM tooling (AutoCAD, Plant 3D, CADvent, Revit) integrated with engineering calculation software (C.A.T.S. for heating/cooling loads and pipe/air-duct networks, Solar) and manufacturer-neutral building automation via open BACnet interfaces. Specialized capabilities include GMP/FDA-compliant clean-room and pharmaceutical-facility qualification (DQ, IQ, OQ, PQ plus URS, QMP, RA) and AGFW-certified district-heating energy and CO2 auditing. Staff hold certifications from DGNB, DIN 14675, VdS, AGFW, and VDI 6022/6023, which function as gating credentials for regulated pharmaceutical, energy, and public-sector work.

GESA operates a project-based, professional-services revenue model billed per engagement under HOAI fee structures, with revenue not publicly disclosed. It sells directly to enterprise clients — predominantly German pharmaceutical manufacturers (e.g., ONCOTEC, medac, Bausch + Lomb, GSK, Menarini–Von Heyden), energy utilities (SachsenEnergie AG Dresden, Stadtwerke Riesa), public-sector building owners (HTW Dresden, Sächsisches Immobilien & Baumanagement), and residential developers — through direct field engagement and industry reputation. Projects are delivered nationally across all German federal states by GESA's own engineering teams, with no reseller or partner distribution layer. Following a management succession on 1 January 2024, Björn Böhme, Sebastian Hoffmeister, and Heiko Schubert now lead as Geschäftsführer, with the prior directors retained as Prokuristen.
