Hl-technik Ag

What Hl-technik Ag does

HL-Technik AG is a Swiss consulting engineering firm founded in 1991 in Zürich, providing integrated HLKKS+E planning services — covering Heating, Ventilation, Climate/Cooling, Sanitary, Drainage, and Electrical disciplines — for building projects in the residential, commercial, industrial, hospitality, education, healthcare, and public sectors. The firm operates from two offices (Schaffhausen headquarters and Zürich branch) with approximately 30 employees, and has delivered more than 400 projects over 35 years, ranging from CHF 374,000 to CHF 120 million in scale. Notable clients include Mobimo Management AG, BVK Personalvorsorge des Kantons Zürich, Coop Immobilien AG, AXA Leben AG, Emil Frey AG, and the Kanton Schaffhausen government.

The firm's core technology is BIM-based integral planning using Autodesk Revit/MEP, deployed company-wide since 2017 with all staff trained on the platform. Nine specialist disciplines are coordinated under a single project plan and a single point of contact (Gesamtprojektleiter HLKKS+E), eliminating interface losses between trades. Methodology follows the SIA 102/108 framework across six phases from needs formulation through operational lifecycle management. Project types include Minergie-certified buildings, 2000-Watt-Gesellschaft compliant energy systems, and heritage-sensitive renovations, with engineering fees typically set at 8-12% of the HLKKS+E investment sum.

Revenue is generated exclusively through professional services fees structured per SIA Ordinance 108, with multi-year contracts spanning full project lifecycles. The go-to-market is relationship-driven direct enterprise engagement, targeting property owners, developers, housing cooperatives, cantonal and municipal governments, and corporate clients across German-speaking Switzerland. Since January 2023, HL-Technik has operated as part of the CSD Gruppe network of specialized engineering brands, with the Zürich branch co-located at CSD Ingenieure AG premises, while retaining independent operations and brand identity.
