On March 13, 2025, Rail Baltic Estonia OÜ, the company in charge by the state-owned, to manage the construction and development of Rail Baltica in Estonia, announced two alliance groups as the winners of the largest public procurement in Estonia’s history – tasked with building the railway line running through the country.

Rail Baltica is a high-speed rail project partially funded by the European Union, involving Estonia, Latvia, Lithuania, Poland, and Finland via a maritime connection. The project aims to connect the Baltic countries with Central and Western Europe.

Ingerop is part of the alliance responsible for the full design and build of the mainline from Pärnu to the Latvian border in Ikla, spanning 58.08 km. The consortium also includes the construction companies Bouygues Travaux Publics (France), Budimex SA (Poland) and KMG Infra OÜ (Estonia), as well as the engineering firm WSP Finland Oy (Finland). The total contract value is estimated at €332 million, with options bringing the potential total to approximately €392 million.

Futerro, Belgian company specialised in the production of lactic acid, lactide (two platform molecules) and PLA (polylactic acid), has launched the engineering and the Front End Engineering Design (FEED) – called “Avant-Projet Détaillé” in French – for its future European biorefinery to be located at Saint-Jean-de-Folleville between Rouen and Le Havre (76).

The company has called upon the French technical expertise of the Ingerop Group to finalise the environmental and construction authorisations, which should be submitted to the French government within the next few months.

Through combining various technologies (fermentation, polymerisation and recycling), Futerro aims to develop a green chemistry and a renewable polymers sector, reducing the carbon footprint of French industry with an objective not just of decarbonisation, but also of defossilation.

Ingerop has been appointed by the joint venture of Eiffage Génie Civil SAS (France), Budimex S.A. and Rizzani de Eccher S.p.A (ERB Rail) as the design coordinator on the civil engineering and track-laying contract for the construction of the Latvian section of Rail Baltica. ERB Rail was awarded the FIDIC contract by Eiropas Dzelzcela Linijas (EDZL), the national executive agent of Rail Baltica in Latvia on 21st December 2023.

The 3.7 billion euro, 230-kilometre-long Latvian section incorporates 175 engineering structures and 11 wildlife crossings. It is aimed at integrating the Baltic States into the European rail network, linking Helsinki in Finland with Warsaw in Poland. The track design will allow passenger trains to travel at 249 kilometres per hour and for freight trains to travel at 120 kilometres per hour.

“We look forward to working with Eiffage again, having worked closely together on HS2 and the Bretagne-Pays de la Loire HSR in France. The Rail Baltica project will strengthen our relationship with Eiffage as well as Rizzani de Eccher and Budimex”, Yves Metz, President of Ingerop said.

In its “Vision 2027” strategic plan, Ingerop has set itself the ambition of developing new services in the industrial sector in order to play an active part in the reindustrialisation of France.

As part of France 2030 investment plan, worth more than €50 billion, the French government is aiming to recover France’s position at the forefront in certain industrial sectors and invest in sustainable development for a green, low-carbon industry.

As an engineering and consultancy company, Ingerop helps its industrial clients to be more efficient, in particular by developing low-carbon industrial processes and products.

An acquisition in line with Ingerop’s development strategy

The integration of Deltaedre Engineering in the Ingerop Group will contribute to Ingerop’s development strategy. It will enable the Group to consolidate its skills in the process engineering sector, but also to benefit from its expertise in the use of industrial software.

By joining the Ingerop Grand Ouest regional team of 160 employees, Deltaedre Engineering will strengthen the industrial process team from Ingerop’s offices in Bordeaux.

Founded in 2008 near Toulouse, DeltaEdre Engineering specialises in the engineering of material transformation processes, from design to validation of the industrial process.

Deltaedre Engineering has worked with several major players in the fine chemicals, agri-food, green energy and pharmaceutical industries, including Michelin at its Bassens site, which specialises in the manufacture of synthetic elastomers, Guerbet, a pioneer in diagnostic imaging, and Euralis, an agricultural cooperative group

For the past four years, Ingérop, a major player in engineering and consulting, has been working with SIRRA (Syndicat Isérois des Rivières Rhône Aval) on a project to restore the environment and protect against flooding in the Sanne and Dolon watersheds in Isère. Thanks to an innovative collaborative method involving all stakeholders, a development scenario for the two watersheds achieved general consensus. On the strength of its expertise and the support of the stakeholders for the approach, Ingérop will now carry out the preliminary design for this scenario.

SIRRA, A SYNDICATE FOR AQUATIC ENVIRONMENT MANAGEMENT AND FLOOD PREVENTION

Located in the Isère region of France, SIRRA’s objectives include preserving and restoring the proper functioning of aquatic environments, as well as preventing and protecting human interests from the impact of flooding. Within this framework, the syndicate is managing and coordinating a Flood Prevention Action Program (PAPI) for the Sanne and Dolon watersheds, as part of their development plan. The program focuses on a number of areas: raising public awareness of the risks, taking account of flood risk in urban planning, and reducing vulnerability.

In 2019, SIRRA launched a call for tenders to carry out a comprehensive study of the territory’s flooding potential, knowledge of how rivers function and knowledge of aquatic environments (state of rivers and surrounding environments). Ingérop won the tender, thanks to its technical expertise and in-depth knowledge of the area.

DEVELOPMENT SCENARIOS

To carry out this mission, Ingérop joined forces with two partners: its subsidiary Géos, for the geotechnical component, and Ginger Burgeap, a consulting firm specializing in environmental studies.

Three phases were carried out:

• Diagnosis of the area: Ingérop and its two partners collected and analyzed existing data to understand how the environment functions (flood history, environmental degradation, etc.). They also carried out a detailed analysis of the hydraulic functioning in the event of flooding. The group carried out hydraulic modelling (computerized flood simulations) based on very precise topographical data and land-use characteristics. An inventory of the current situation and a list of existing structures were thus drawn up.
• Vulnerability study of the territory: this study enabled us to highlight sensitive areas, where property and people are particularly exposed to the risk of flooding. The aim of this phase was to provide a summary of the area’s vulnerabilities (exposure to flooding and environmental degradation), in order to define preservation/restoration and flood protection objectives.
• Analysis of development solutions: the analysis of multiple solutions assessed their contribution to achieving the set objectives (flood reduction, improvement and restoration of environmental conditions). The effectiveness of development solutions was quantified using models (local, generalized effects, etc.). This numerical technique was used to select several combined development scenarios.

In June 2023, 4 combined development scenarios were presented to the steering committee partners (elected representatives, associative members, economic partners, etc.) to present the results of this analysis and enable collective reflection, through workshops. At the end of this collaborative process, a development scenario was selected. Ingérop is assisting SIRRA in the next stages of refining the characteristics of the selected project.
