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.

Ingerop group, is pleased to present the 10 projects selected for the fourth season of its IN3 intrapreneurship programme.

The project leaders, all employees of the group, will receive support for nearly a year to transform their ideas into a structured offering that creates value for its customers.

Engineering consultancies Rendel Ingerop Pty Ltd and Aspec Engineering have opened a joint office on Grenfell Street, in the heart of Adelaide’s central business district. The new Adelaide office puts Rendel Ingerop and Aspec Engineering in close contact to key clients and comes in response to several large contracts and investment in South Australian mining, infrastructure and maritime projects.

The Adelaide office will be led by Director Antonio Perez, a Chartered Professional Engineer with over 25 years’ experience. Antonio commenced his career in Sydney and later moved to Perth where he spent several years working in the mining, maritime and industrial sectors; in particular on Rio Tinto’s port expansion at Cape Lambert and BHP’s Southflank Mine

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.

On the occasion of the World Nuclear Exhibition, the Ingerop Group reaffirmed its position as a major player in engineering for energy transition projects and presented three of its ongoing assignments.

Ingerop: A Key Player in Nuclear Engineering

Whether for EPRs, Small Modular Reactors (SMRs) or facilities related to the industry (research, fuel cycle, waste management, etc.), Ingerop supports its clients throughout the entire project lifecycle: feasibility studies, environmental and impact assessments, detailed design, client consulting services, supervision of construction, testing and commissioning. The Ingerop Group combines methodology, rigour, innovation, technical expertise and safety assurance to guarantee the performance and regulatory compliance of these installations. The ISO 19443 certification obtained by our nuclear teams since 2022, and more recently by our Scientific Calculation Department in Rueil-Malmaison, reflects this commitment.

Ingerop’s Expertise Supporting the French State’s EPR2 Plan

With its EPR2 plan, France is entering a new era for civil nuclear power. The plan aims to build six new reactors – with eight more as an option – across three sites in France: Penly (Seine-Maritime), Gravelines (Nord) and Bugey (Ain).

Less expensive and faster to build and commission, these EPR2 reactors are designed to improve the performance and safety of existing reactors while accelerating the revival of the national nuclear fleet.

In this context, Ingerop and its subsidiaries — including Actierra, a specialist in ecological issues and biodiversity protection — are supporting the design and construction of the facilities associated with these new reactors. More than 100 engineers and technicians from the Group’s nuclear infrastructure teams will be mobilised.

International engineering consultancy Rendel Limited, subsidiary of the French-owned Ingerop Group, is excited to announce its expansion into Ireland, with the creation of a new Irish subsidiary company, Rendel Ingerop Ireland Limited, and the opening of a new office in Dublin.

Rendel has a long history of delivering successful projects across Ireland, having previously worked on Dublin Metro North, Limerick Southern Ring Road, Dublin Port Tunnel, Mulroy Bay Bridge, Foyle Bridge, Campus Ireland stadium, East Wall Road Bridge, Pearse Bridge, Waterford Bridge, Athlone Bypass and Lower Lee Crossing.

As part of a major development project for the Lyon metropolitan area, the second most populous metropolitan area in France, Sytral Mobilités has entrusted Ingérop with the construction of the T8 tram line.

Recognised expertise in mobility

Ingérop specialises in the design, construction and implementation of transport infrastructure in operational environments, expertise that is essential for this large-scale project. The connections to existing lines (T2, T5), which present major technical challenges, will be carried out in a dense urban environment, with significant geometric and phasing constraints.

With its team of experienced consultants, Axfer supports major players in the sector, including SNCF and RATP, and is continuing to grow to meet the increasing needs of this market throughout France.

Keeping pace with the railway industry

The railway sector has been experiencing strong growth in recent years, as confirmed by the Transport Regulatory Authority in a recently published report. This growth is accompanied by an increased need for technical and engineering expertise in the fields of electrical engineering, civil engineering and, more generally, railway project management. Axfer was born out of this need, a dedicated engineering company that draws on the group’s recognised expertise to support its long-standing clients and the major players in this industry – SNCF Réseau, SNCF Gares & Connexions and RATP – in their strategic projects. With several framework agreements dedicated to these activities, the Ingérop group confirms the relevance of this positioning.

Ingérop announces the acquisition of Auxitec Técnica y Control, a Spanish company specialising in systems engineering for railway infrastructure, particularly in the field of railway signalling for conventional and high-speed lines.

This transaction marks a new stage in Ingerop’s development in Spain, enabling it not only to strengthen its position there but also to consolidate its expertise in transport automation and systems engineering for railway infrastructure.

For Auxitec’s employees, this integration represents an opportunity for international development and the chance to contribute to major structural projects led by the Ingerop group, as well as access to new key customers.

Auxitec Técnica y Control: international leader in services, consulting and engineering for transport automation

Based in Madrid, Auxitec has a team of 25 people and has solid experience in international projects (Mexico, Egypt, Azerbaijan, etc.), while also having a strong presence in the Spanish national rail market. Auxitec has been recognised as an innovative company (PYME Innovadora label) by the Spanish Ministry of Science and Innovation, in recognition of its research and development efforts in the railway sector, notably with projects developed to improve the safety of people working in the railway sector.
