Spie batignolles supports the transformation of the Adolphe de Rothschild Foundation Hospital

This major project, designed to modernize hospital infrastructure and meet growing needs for specialized care, represents a major advance for the fields of neuroscience and ophthalmology.

February 12 marks a key milestone with the official laying of the first stone of this operation launched to respond to public health issues.

For Gianni Angelosanto from Spie batignolles ile-de-france: "Spie batignolles, which has multiple hospital references throughout France (American Hospital of Paris, SAMU de la Timone in Marseille, etc.), proves the ability of its entities to meet very demanding specifications in terms of medical infrastructure."

A transformation project to serve the health of tomorrow

The Adolphe de Rothschild Foundation Hospital is a private healthcare institution of collective interest. This university hospital is recognized worldwide for its expertise in neuroscience, ENT and ophthalmology, in the fields of care, training, research and innovation. It carries out nearly 460.000 consultations and technical procedures each year, as well as more than 50.000 emergency room visits. Its Foundation has been recognized as being of public utility since 1909.

Launched in 2023, its “Hospital 2030” expansion and restructuring program aims to anticipate changes in medical practices as well as technical and organizational innovations, to respond with excellence to the growth of pathologies such as neurodegenerative diseases, strokes, deafness, AMD, glaucoma and myopia. This profound transformation of care pathways will be accompanied by an increase in the number of hospital beds and outpatient places, as well as significant improvements in the living environment of hospitalized patients and care teams.

For Julien Gottsmann, Director General of the Adolphe de Rothschild Foundation Hospital: "Today is a milestone in the history of our hospital. By laying this first stone together, we are taking a decisive step: moving from design to construction, from project to concrete realization. This first stone symbolizes much more than an architectural act: it embodies our vision, our commitment and our audacity."

A synergy of expertise from different entities of the Spie Batignolles group

All of the various works to be carried out as part of the extension project of the Adolphe de Rothschild Foundation Hospital have been entrusted to a group led by Spie batignolles ile-de-france (agent), Spie batignolles présance ile-de-france, Spie batignolles fondations, Spie batignolles énergie and Hervé Thermique.

The project, with a total cost of 45,7 million euros for its "extension" component, will take place in two major phases to have as little impact as possible on the continuation of the hospital's activities.

• The first phase, entitled "Adaptations of Existing Facilities". It includes major network diversions, the demolition and cleaning of the future extension's right-of-way, the creation of a buried technical gallery under the Moreau wing, as well as the commissioning of new technical and care equipment. This includes a temporary building installed at 58, avenue Mathurin Moreau, generators, refrigeration units, a medical fluid platform and an interventional neuroradiology room, etc.

This new equipment replaces old devices that were removed, thus allowing the emergence of the future building at the heart of the hospital's main site, located at 25-29 rue Manin in the 19th arrondissement, opposite the Parc des Buttes Chaumont.
This work was carried out on an occupied and constrained site, with particular attention paid to minimizing disruption to hospital activities.

Constructive methodologies have been adapted as part of an extensive dialogue with all teams to limit their impact by prioritizing periods of lower activity at the Foundation.

The success of this phase was made possible thanks to the expertise of the teams and the organization of weekly coordination meetings with the various technical departments of the hospital, in order to best manage the interfaces between the work and the continuation of hospital activities in conditions of hygiene and safety.

• The second phase, called “New construction of an extension”.

It is planned for a duration of 28 months, will include the construction of an extension in the heart of the block, connected to the existing facades, as well as the restructuring of the Pavillon Moreau. Several key stages of the project have already been completed, including structural demolitions, the creation of new technical and care equipment to replace the existing ones, as well as the commissioning of a temporary building located at 58 avenue Mathurin Moreau.

The latter made it possible to relocate certain hospital activities, including access to outpatient units, and to ensure continuity of services during the works.

To do this, the Spie batignolles présance ile-de-france teams carried out the structural demolition of the connecting footbridges, the R+2 gallery and the auditorium in the Moreau inner courtyard, in order to allow the construction of the foundations of the future building.

• Basement recovery required

Between December 2023 and August 2024, in the second basement of the existing building, the Spie batignolles fondations teams worked on the construction of the foundations of an underground technical gallery allowing the diversion of existing networks, in particular a high-voltage electrical network, associated technical premises and the temporary building with the underpinning and maintenance of existing structures.

For this work, they used a Beretta T28 type drill with a reduced mast whose height is less than 3 m, to adapt to the dimensional constraints of the site.

It enabled the construction of 26 micropiles of 13 to 19 m in length, depending on the areas treated.

• Between December 2024 and May 2025, major deep foundation works and backfilling of underground quarries

As of December 2024, Spie batignolles fondations has begun construction of the deep foundations and the retaining wall in Lutetian wall of the new building. 70 single bored piles 25 m deep are on the program.

The company is currently executing the first 38 piles up to 30 m deep (with an average of 25 m), with diameters of 600/800/1000 mm.

After this first phase of deep foundations, 1 m³ of cement-based grout will be injected during February to fill in the underground quarry.

Finally, in April 2025, the teams will resume work on special foundations to build the last 32 piles with an average depth of around 20 m.

The choice of the simple bored pile responds to two major challenges which are the composition of the soil and the search for techniques with lower acoustic levels taking into account the constraints of the site and its environment. The use of an SR40 drill guarantees more limited nuisances compared to other equipment.

At the end of this phase of foundations and quarry filling, the Spie batignolles ile-de-france teams will launch the infrastructure work for the new building.

Spie batignolles énergie was commissioned to design new HV/LV cables as well as a new autonomous safety source for the existing site. A temporary HVA power supply was set up for the HVA delivery station, as the current Enedis arrivals are located within the footprint of the future building.

The entire project, due for delivery at the end of December 2026, aims to increase hospital capacity by 30% over a total surface area of ​​9.034 m². The removal of the construction site facilities is scheduled for March 2027.

Particular attention paid to local residents and nuisance management

Aware of the challenges associated with a construction site of this scale in a dense urban environment, Spie batignolles ITM+ (an entity of Spie batignolles fondations) has set up a system for continuous monitoring of noise and vibration pollution in order to limit the impact of the work on the neighbourhood.

Since the start of the work and for a total duration of 38 months, measuring stations equipped with microphones and class 1 accelerometers have been analyzing noise levels and vibrations in real time. Weekly monitoring is provided via the Argos® platform, with automatic alerts in the event that the thresholds set by the acoustic design office are exceeded.

A project that respects heritage and the environment

Located in the heart of the 19th arrondissement of Paris, opposite the Parc des Buttes-Chaumont, the Adolphe de Rothschild Foundation Hospital is a protected site with a strong architectural identity, which will be preserved in the new building to be constructed.

The project includes the renovation of historic facades and the development of landscaped areas in keeping with the original Anglo-Norman setting and the location of the establishment opposite the large wooded park of Buttes-Chaumont. This greening contributes to improving the quality of life of patients, visitors and hospital staff.

In an eco-responsible approach, the Adolphe de Rothschild Foundation Hospital was keen to include the operation in the requirements of low-carbon construction, notably integrating advanced energy management systems and bio-sourced materials, guaranteeing energy efficiency and sustainability.

This technically complex extension project, carried out in an urban environment, while preserving the continuation of the hospital's activity and therefore access to the highly specialized care offered by the Foundation, constitutes a collective feat in the service of a major advance for specialized medicine in France and the strong symbol of a lasting commitment to patients and health professionals.
