Stocklin und Partner AG, Ingenieurburo

What Stocklin und Partner AG, Ingenieurburo does

Stöcklin und Partner AG, Ingenieurbüro, is a privately held Swiss engineering consultancy headquartered at Flurstrasse 56, 8048 Zürich. Founded in 1961 by Bruno Stöcklin and reorganized as a stock corporation in 1983, the firm has operated continuously for over 60 years. It functions exclusively as a pure planning office — it does not execute installations and is neither a manufacturer representative nor a product reseller — which positions it as a manufacturer-neutral specialist across electrical and building automation projects.

The company's core services span electrical installation planning for residential, commercial, and industrial buildings; building automation using bus systems such as KNX/EIB, Dali, and Luxmate; data center infrastructure design (cold aisle containment, redundant power and UPS systems, heat recovery, cooling optimization); communication cabling (copper and fiber); and energy supply planning including medium-voltage systems up to 22 kV. S+P plans systems it does not build, using computer-aided electrical schematic tools adopted in 1985, and acts as specialist construction supervisor and invoice verifier on behalf of clients. The 2011 acquisition of Martin Gallmann Engineering added building automation specialization, and a Green Energy advisory line addresses CO2 reduction, standby management, and building envelope consulting.

S+P serves property owners and developers, architects and general planners, public sector clients (notably the City of Zurich's school facilities since 2012), data center operators (Data Center Wien, 2014–2023), district energy utilities (Limeco AG since 2019), and industrial/logistics firms (Syntegon Beringen 2006–2023, Planzer Wädenswil). Revenue is generated through project-based professional service fees determined per engagement, with the firm currently led jointly by Martin Gallmann and Alexander Guntersweiler since August 2022. Operations are predominantly Zurich-centric, with occasional cross-border engagements in Austria and Germany.
