What SNZ Engineers and Planners does
SNZ Ingenieure und Planer AG is a Zürich-based, employee-owned Swiss engineering and planning consultancy that has operated continuously since 1959. The firm delivers infrastructure consulting across the full project lifecycle — from feasibility studies and master planning through construction supervision — for Swiss municipalities, cantons, federal agencies, and the Swiss Federal Railways (SBB). Its work is organized across four departments: Traffic Planning (Verkehrsplanung), Project Development (Projektentwicklung), Project Realization (Projektrealisierung), and Railway and Civil Engineering (Bahn- und Ingenieurbau), covering traffic modeling, public transport strategy, pedestrian and cycling infrastructure, road construction, and railway construction. Marquee engagements include the Ceneri Base Tunnel, Limmattalbahn light rail, MehrSpur Zürich-Winterthur capacity expansion, and SBB's BZU 23 accessibility upgrade program under the BehiG disability equality law.
The firm employs approximately 70 specialized professionals at its Zürich Oerlikon headquarters and uses an established engineering technology stack centered on Building Information Modeling (BIM), CAD platforms (Allplan, Microstation), and the PTV traffic simulation suite (VISUM for strategic traffic modeling, VISSIM for mesoscopic and microscopic flow simulation). It has maintained ISO 9001 certification continuously since 1997, signaling process maturity that is typically a procurement prerequisite in Swiss public-sector tenders. To deliver projects whose scope exceeds its internal capacity, SNZ regularly operates as a member of Ingenieurgemeinschaften (IG joint working groups) with peer firms including ACS-Partner AG, Gähler und Partner AG, F. Preisig AG, WBI Wüst Bauingenieure AG, and AeBo.
Commercially, SNZ generates revenue through project-based professional services fees negotiated individually with public-sector clients, supplemented by multi-year framework contracts (notably with SBB for track renewal planning under IG Mitte) and joint-venture participation in large infrastructure programs. The go-to-market is sales-led and relationship-driven, with brand visibility supported by membership in suisse.ing, VSS, and SVI industry associations. All revenue is generated within Switzerland; the company is privately held as an Aktiengesellschaft with shares distributed among senior employees since the 2000 restructuring, with no venture capital, private equity, or parent-company involvement.
