What Rampini & Cie SA Entreprise de construction does

Rampini & Cie SA is a Geneva-headquartered civil engineering and construction firm operating as a Swiss Société Anonyme (SA) under private ownership. The company offers a full-stack portfolio across 11 service lines — buildings, renovation/transformation, demolition and earthworks/special works, 24/7 emergency response, underground canalisation networks, transportation infrastructure, art structures (bridges, tunnels), lake and river engineering, floor coverings, drilling and cutting, and exterior arrangements. With 32 employees and 80 years of operating history, Rampini executes both standalone projects and consortium tenders, with disclosed lot values ranging from sub-CHF 1 million service jobs to CHF 23.8M flagship commissions such as the Geneva Airport underground gallery, alongside participation in multi-partner consortium megaprojects exceeding CHF 16 million.

The company's go-to-market is project-based competitive tendering for both public and private clients, with no standard rate card and no public pricing disclosure. Rampini's customer base is dominated by Geneva-area public-sector and quasi-public entities: municipal and cantonal administrations across communes (Vernier, Bernex, Satigny, Plan-les-Ouates, Carouge, Chêne-Bougeries, Lancy, Anières, Presinge, Avusy, etc.), utilities such as SIG (Services Industriels de Genève) for water and district heating, transport authorities including TPG and SBB/CFF for tram and railway works, Geneva Airport for aviation infrastructure, and HUG (Geneva University Hospitals) for healthcare campus works. Private-sector exposure includes luxury hospitality (Kempinski via the GENILAC district-heating connection) and real estate developers.

The business model relies on direct bid-and-build execution backed by 5,400 training hours per year and CHF 373,000 in workforce development, supporting a 98% client repeat-intention rate. There is no evidence of software, digital platform, or proprietary technology; differentiation is grounded in deep local relationships, multi-disciplinary construction know-how, and the ability to mobilize both direct workforce and consortium partners on large public infrastructure tenders within the Canton of Geneva.
