SPIE will carry out the low-voltage and low-current works on the metro line South


Paris, 23 February 2021SPIE CityNetworks, a French subsidiary of the SPIE group, the independent European leader in multi-technical services in the areas of energy and communications, has been selected by RATP to carry out the low-voltage and low-current works on the transport infrastructure of the automatic metro line 14 South. The 14-kilometre underground extension will connect the current terminus of line 14, Olympiades, to the Orly airport station to be constructed.

Recognised expertise in the area of public transport

As a key player in mobility, SPIE benefits from proven expertise in the area of transport and mobility engineering, particularly when it comes to rail. As well as being rooted firmly in the Ile-de-France region, SPIE CityNetworks draws on a Transport & Mobility division that strives to support the projects of tomorrow.

In the light of this, SPIE CityNetworks has positioned itself perfectly and has been entrusted with carrying out all the high and low current works on line 14 South, in partnership with Semeru-Fayat. This is a sign of trust on the part of RATP, which was given overall responsibility to head up this operation, under the external direction of ELIOS, by Société du Grand Paris. SPIE will be responsible for project management, studies and works. The Group will provide the services associated with the power supply, the line infrastructure, all the lighting facilities, and all the operational and security equipment (cameras, information boards, telephone equipment, sound systems, etc.). SPIE will also take responsibility for the various auxiliary equipment and installations required at the stations (HVAC, lifts, mechanical escalators, etc.). All of these services will be done for the five stations to be constructed, the 12 ancillary structures allocated and the 14 kilometres of tunnel making up the extension.

Logistic requirements and a tight schedule

SPIE stands out for its ability to offer robust, efficient and tailored solutions, enabling projects to be completed within the set deadlines. Above and beyond the technical requirements, the Transport & Mobility experts at SPIE CityNetworks were able to foresee many other aspects such as equipment storage or mobilising their network of subcontractors to manage the peaks in activity. Their collaborative approach and flexibility will be essential for a project that involves a huge number of stakeholders.

BIM, a novel method in the transport sector

While coordinating and summarising the various technical lots involved, a 3D model was created. “BIM may be becoming commonplace in the building sector, but it’s still very much an innovation in transport. The realisation of line 14 South is one of the first RATP projects where BIM has really come into its own in the studies and summaries carried out between the various sectors”, explains Guillaume Bouvatier, Department Head at SPIE CityNetworks and Project Manager.

Work on site will begin at the end of 2021, following a very short and ambitious study and summary phase of around nine months. The peaks of activity on site will involve up to 80 staff members. A major contract for SPIE CityNetworks, providing an opportunity to face new challenges and offer our expertise to Ile-de-France citizens.
