With this acquisition, Ingérop continues its expansion in French-speaking Switzerland alongside a major engineering player in the building and industrial sectors.
This transaction is fully in line with the group’s growth strategy, which aims to strengthen its regional presence both in France and internationally, whilst developing its expertise across the entire engineering value chain. In Switzerland, following the acquisition of Geos in 2005 and SGI Suisse in 2023 (which became Helveos in 2025), Ingerop is taking a new step forward in its development and now has a workforce of nearly one hundred employees in the country.
The Pierre Chuard Group: an expert in technical installations and energy efficiency in buildings in French-speaking Switzerland
Based in Lausanne and Geneva, the Pierre Chuard Group comprises nearly 50 staff across three complementary entities:
- Chuard Ingénieurs – Heating and ventilation systems,
- Fluides Concepts – Sanitary and industrial systems,
- Sorane – Building energy performance.
The Pierre Chuard Group is involved throughout the entire project lifecycle, from design studies through to site supervision and operational audits on large-scale projects. In 2025, the group achieved a turnover of 6.5 million Swiss francs.
Its areas of expertise include, in particular, heating, ventilation, air conditioning and plumbing; complex thermal and energy systems; energy-efficient building design; advanced thermodynamic simulations; building physics; renewable energy; geothermal energy; certification schemes (Minergie, DGNB, SNBS); the design of neighbourhood energy supply systems; and advanced building envelope design.
The group also possesses recognised expertise in high value-added technical installations, particularly in the hospital sector (operating theatres, clean rooms, laboratories) and in infrastructure requiring high energy performance or complex fluid management.
Since its foundation, the Pierre Chuard Group has contributed to several major projects in French-speaking Switzerland, including the Rolex Learning Centre, the Hôtel Métropole in Geneva, the Audemars Piguet Hôtel des Horlogers, Geneva International Airport, the Tulipe building in Geneva, the new Comédie de Genève, the Innovation Quarter at the Swiss Federal Institute of Technology in Lausanne, Morges Hospital, the Spark industrial building and the Foundation for Public Research in Geneva. The company thus supports a wide range of public and private clients across the commercial, residential, industrial, hospital and hospitality sectors.
