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.

Déjà engagé sur de nombreux projets majeurs du territoire et ayant fait récemment l’acquisition de Valétudes, Ingérop renforce sa présence à Dunkerque avec l’ouverture d’une nouvelle implantation.

Dunkerque, un territoire stratégique au cœur des grandes transformations industrielles et énergétiques

Avec une concentration de projets industriels, énergétiques, portuaires et de mobilité, l’agglomération dunkerquoise s’impose comme un territoire central des grandes transitions en cours.

Ingérop y accompagne de nombreux projets structurants qui mobilisent l’ensemble de ses domaines d’expertise : industrie, énergie, ville, eau, bâtiment, transport, infrastructures et mobilités. A l’échelle du territoire des Hauts-de-France, on peut citer : Canal Seine Nord Europe, tramway de Lille et de sa couronne et bus à haut niveau de service (BHNS) sur la Métropole Européenne de Lille, Centre de Conservation de la Bibliothèque Nationale de France à Amiens. Il en est de même sur le territoire dunkerquois avec les projets d’extension du port de Dunkerque (projet CAP2020), de contournement de Cappelle-la-Grande et de BHNS de la Communauté Urbaine de Dunkerque.

Dans le secteur industriel, Ingérop compte parmi ses clients historiques locaux ArcelorMittal, pour lequel il a récemment réalisé les études de génie civil du projet Electryck de création d’une nouvelle ligne de production d’aciers destinés aux véhicules électriques, Colas où le groupe était maître d’œuvre pour la déconstruction de l’ancienne raffinerie de BP à Dunkerque. Ingérop assure de plus la maîtrise d’œuvre du projet XTC Orano d’usine de production de Matériaux Actifs de Cathode pour batteries. Dans le domaine de l’énergie, Ingérop est chargé de plusieurs missions d’études et d’aménagement pour l’EPR2 à Gravelines pour le compte d’EDF.

With this sixth acquisition in Germany, Ingerop strengthens its value chain in Germany by complementing its offer with architectural skills

Bollinger + Fehlig Architekten: German precision and restraint

Founded in Berlin in 2000, Bollinger + Fehlig Architekten develops a wide range of urban construction projects and designs or refurbishes residential properties, offices, laboratories, hotels and educational buildings. Its innovative and unconventional proposals address the operational challenges of construction sites whilst ensuring that clients’ deadlines and budgets are met.

Building on its experience in the construction and industrial sectors in Germany, Ingerop sought to expand its offering by incorporating expertise in functional building architecture: Bollinger + Fehlig Architekten emerged as the obvious choice.

With a fifth consecutive year of double-digit growth, Ingerop confirms its momentum and strengthens its position among leading engineering players in France and internationally.

Sustained growth in France and internationally

In 2025, Ingerop generated consolidated revenue of €507 million, up 11% compared with 2024. Activity remains primarily in France, accounting for more than two-thirds of total revenue. Internationally, revenue has exceeded 31% for the past three years, driven by Germany (10% of revenue), the United Kingdom (5%), South Africa (2.5%), Australia (2%) and Spain (2%). Operating income remains stable at around 5% of revenue. At the end of March 2026, the order backlog stood at €777 million, representing 17 months of activity.

The Group is continuing its development strategy in France with the acquisition of the engineering consultancy Valétudes, which specialises in hydraulic and environmental infrastructure. This transaction enables the Group to strengthen its position in strategic markets and to develop solutions tailored to the challenges posed by climate change.

Valétudes, a key player in river, port and environmental engineering

Founded in Valenciennes, Valétudes is recognised for its expertise in projects relating to hydraulic, river and port infrastructure, as well as the regeneration of brownfield sites. Its teams undertake project management and preliminary design work for national port, maritime and river operators, aquatic environment managers and local authorities.

Valétudes has contributed to numerous landmark projects and has already had the opportunity to collaborate with Ingérop, thereby laying the foundations for a solid and effective partnership.

The complementary nature of Ingerop and Valétudes is based on:

• a natural synergy between strategic vision, comprehensive engineering and on-the-ground expertise,
• a response particularly well-suited to the challenges of the North-East region, a complex and changing territory;
• the creation of value that is commercial, operational and regional in nature.

Ingérop est heureux de présenter les 10 projets sélectionnés dans le cadre de la 4^ème saison de son programme d’intrapreneuriat IN³.

Les porteurs de projets, tous collaborateurs du groupe, vont bénéficier d’un accompagnement de près d’un an pour transformer leur idée en une offre construite et créatrice de valeur pour ses clients.

Ingerop is creating a foundation to pass on its passion for its professions, share its commitment to excellence and place people at the heart of its project to support and assist those who want a better life.

Housed by the Fondation de France, whose mission is to work directly in the field to provide solutions that closely match needs, the Ingerop Foundation intends to draw on its own network in France and internationally to offer its technical expertise and, above all, the interpersonal skills of its employees to the benefit of all.

Supporting projects that will enable everyone to find their place in a sustainable world: the vision of the Ingerop Foundation.

Olivier Poulet, President of the Ingerop Foundation, is a young retiree who worked for the Group for 20 years, notably as Regional Director for the Mediterranean and Indian Ocean. For him, as for François Lacroix, Scientific and Technical Director, and Marie-Pierre Fally, Director of Corporate Social Responsibility and Integrated Management Systems, there is a need to pool resources in the countries where Ingerop operates. Within the Group, there is genuine recognition of individual merit and supportive guidance that allows everyone to develop according to their abilities, whether technical or interpersonal. It was therefore only natural that the Foundation was created to strengthen and structure existing individual initiatives within Ingerop, enabling everyone to find their place and thrive in a sustainable world.
