What AJS ingenieurs civils SA does

AJS ingénieurs civils SA is a privately held Swiss civil engineering consulting firm founded in 1960 in Neuchâtel, organized as a Société Anonyme. The company delivers professional engineering services across six domains: Structures (buildings, conservation, and art structures/bridges); Génie civil (roads, tunnels, and railways); Voirie et réseaux divers (VRD — utility networks and PGEE plans); Project Management and General Planning; Expertise and Easement; and Innovation (HVAC/electrical installations). It also operates a BAMO (Bureau d'appui au maître d'ouvrage) offering owner-support services to public road authorities. Underlying technology is conventional civil/structural engineering consulting, supported by an ISO 9001-certified quality management system in place since 1997 and applied across the full project lifecycle — feasibility, tender, execution, and supervision.

The firm serves a mix of public-sector clients — notably OFROU (Swiss Federal Roads Office), cantons (Neuchâtel, Geneva, Vaud), and communes — and private-sector enterprises across watchmaking (Hublot, Jaquet-Droz), pharmaceuticals/medtech (Celgene, Stryker), healthcare, and research infrastructure (CERN). Revenue is generated through project-based professional-services fees on public tenders and direct enterprise mandates. The firm has 35 collaborators across its Neuchâtel headquarters and branch offices in Brügg and Geneva, with national and international reach via partnership with RSA (Yverdon) and Frisarom (Bucharest) and majority stakes in Richardet & Associés and TMP (Soleure). Notable reference projects include the Vue des Alpes tunnel (~CHF 80M), the A5 La Béroche highway section (~CHF 450M total), the Lötschberg base tunnel works, the CEVA railway link, and the Hublot Nyon headquarters/general planner mandate (~CHF 21M).
