What ACS-Partner does

ACS-Partner AG is a Zürich-based Swiss civil and structural engineering consultancy founded in 1954, operating from a single headquarters at Gubelstrasse 28 with 11-50 employees. The firm delivers engineering services across six practice areas: Brückenbau/Ingenieurbau (bridge and civil engineering), Infrastrukturbau (infrastructure construction), Hochbau/Industriebau (building and industrial construction), Baudynamik (structural dynamics and seismic engineering), Wettbewerbe (competition participation), and Bauwerkserhaltung (structural preservation). Technical work is executed using CAD and BIM tooling, with specialized computational capabilities for vibration measurement, computational vibration prognosis, and seismic safety assessment.

The firm's client base is dominated by Swiss public authorities — SBB (Swiss Federal Railways), ASTRA (Federal Roads Office), the Canton of Zürich (Baudirektion), and a wide range of municipalities (Stadt Zürich, Gemeinde Hombrechtikon, Gemeinde Gossau, Stadtwerk Winterthur, VBZ, EWZ) — supplemented by enterprise clients in pharmaceuticals (Novartis), energy (Axpo), postal services (Post CH), banking (Raiffeisenbank), and real estate development (PSP Properties, Allreal, Steiner AG). Mandates range from sub-million-franc municipal works to mega-projects such as MehrSpur Zürich-Winterthur (CHF 480 million construction volume) and the Eppenberg tunnel (CHF 148 million).

Revenue is generated through project-based professional services billings, with contracts secured via competitive public tenders (including Projektwettbewerbe where ACS has won numerous first-place rankings) and direct negotiations with private clients. The firm systematically partners within Ingenieurgemeinschaft (IG) consortia — alongside Wüst Bauingenieure, Gähler Partner, SNZ Ingenieure, ILF, Aegerter & Bosshard, and c+s ingenieure — to deliver mandates beyond its standalone capacity. ACS-Partner AG is privately held under Swiss law with no disclosed external investment, acquisitions, or M&A activity.

Revenue model

1. Engineering Consulting and Project Services: ACS-Partner generates revenue by providing civil/structural engineering services on a project-by-project basis for public and private clients. Revenue is earned through feasibility studies, project planning, structural design, construction management, and expert opinions across bridge construction, infrastructure, high-rise/industrial buildings, structural preservation, and structural dynamics. Projects range from small-scale assignments to large infrastructure mandates exceeding CHF 100 million in construction value. The firm operates as a professional services firm with billable engineering hours.
