The Joint Union for Dedicated Lane Public Transport in Martinique and the Martinique Region have decided to implement a public transport system throughout the urban area of Fort-de-France.

13.9 km long, the BRT line will include 18 stations, 2 hubs with park and ride facilities, and a maintenance workshop. At commissioning, the rolling stock fleet will consist of fourteen, 24 m long bi-articulated hybrid vehicles.

Assignment

• Diagnosis and audit of the project
• Assisting in cost control, budget monitoring, funding issues, including the Grand European Project
• Assisting in financial engineering and legal advising
• Assisting in deadline management
• Proposing the legal and financial set-up for the studies, work and operation contacts.
• Assisting in communication activities
• Advising on the selection of rolling stock, intermodal hubs and operating principles
• Technical assistance during design and construction phases up to the BRT commissioning: supervision of contractors, engineers and service providers, follow-up reports, technical expertise
• Assistance during the award of a Public-Private Partnership contract for the design, construction and maintenance: drafting the contract, tendering procedure, negotiation, preferred bidder award.
• PPP contract management up to commissioning

The BRT is inserted in an area where several public transport networks coexist without a common organizing authority (urban buses, intercity buses and taxis). Issues of urban integration and intermodal hubs are mostly complex.

Crossing Nimes along the east-west axis, the future line T2 Tram-Bus represents a major stake for the town. As a backbone for the transport network with 26 stations, 13 hybrid buses and a busway that lengths 11.5km, the line improves the existing urban landscape, promotes social and urban cohesion between the districts and the heart of the town, and helps to develop new ways of living in public spaces. Ingerop leads the operations study, traffic flows and handles hydraulic modelling, regarding the historical constraint of Nîmes with high flood risks.

The 9th tram line in Paris, T9, has the role to replace the bus line 183, which is today one of the most used in Paris area. With a linear of 10.3 km, the T9 line will connect the Door of Choisy (Paris) to the downtown area of Orly, while crossing or skirting the cities of Ivry-sur-Seine, Vitry-sur-Seine, Thiais and Choisy-le-Roi and by mainly borrowing the road RD5.

Features :

• tramway on tyres
• 19 stations
• Frequency of 4 minutes during rush hours

Missions

The project management mission includes:

• systems and the operation and maintenance center: platform, railway, overhead contact airline, energy, low voltage distribution, signaling
• urban developments: various public spaces, roadway systems, utilities, public lighting, traffic lights, urban furniture and landscape
• operation studies and equipment of the operation center: under-floor lathe, lifting columns, painting cabin, maintenance engines as rail-road, …
• development of the administrative files,
• general coordination with the other engineering companies
• scheduling, Piloting & Coordinating and interfaces piloting

The SYTRAL tram network is expanding and requires a new tram maintenance center. The former Fagor industrial zone, located in the immediate vicinity of the heart of the Lyon metropolitan area and connected to the T6 line, will accommodate 66 trams.

Nearly 11,600 m² of storage space and more than 7,000 m² of maintenance workshops, combined with a service station, are planned across various buildings. Nearly 11,600 m² of storage space and more than 7,000 m² of maintenance workshops, combined with a service station, are planned across various buildings designed to meet high environmental and bioclimatic standards. The reinterpreted industrial architecture gives way to bio-sourced materials in a combination of wood, metal, and terracotta. The future operation of the site is being designed with a focus on functionality and ergonomics, as well as natural light. The development of a landscaped strip to the north of the site and extensive work on the facades and noise reduction measures will help to integrate the site into this dense urban environment, while maintaining its industrial character.

The main purpose of the building is to serve as a tram maintenance center, for which Ingerop’s expertise is being mobilized in all its dimensions: layout and track, tram platform, road and utility networks, SLT, hydraulics, LAC, GIS-f, energy/CFO, CFa, depot equipment, etc.

Special features

Following a project management competition, Ingerop was awarded the contract within a multidisciplinary consortium for the technical studies for the buildings, infrastructure, depot equipment and the tramway system as a whole. The acoustic/vibration aspects are being handled by the group’s specialists. Close collaboration with architects, landscape architects and experts in contaminated sites and soils.

Characteristics of the structure

• Tramway service station (sand pits, washing machine), 66 covered storage positions, pit tower, large washing track, tracks on slabs and pits with walkways, etc.
• Parking, landscaping, levelling and hydraulic management.
• Phasing of works with early commissioning of storage.
• Workshop and tertiary premises.

The backbone of Nice Urban Transport System is two tramlines. Line 1, which was opened in 2007 with the support of Ingerop, was one of the first trams to carry an onboard battery in order to cross place Garibaldi and place Massena without any overhead wire. The line is 10km long with 22 stations.

The first stage of Line 2 was opened in June 2018. This new line has three distinctive attributes:

– It operates the next generation of Alstom Citadis tramway

– It uses an innovative energy system consisting of an onboard battery that recharges in 20 seconds when the tram stops at a station. The tramway system does not need any overhead power-charging system

– The line has an underground section of 4km which crosses the historic district of Nice. This specific section includes four “metro-like” underground station

Line 15 South of the Grand Paris Express will connect Pont de Sèvres station to Noisy-Champs, passing through 22 municipalities. With over 300,000 daily users, this automated metro line will ease congestion on the wider metropolitan public transport network.

Ingerop is responsible for the preliminary and detailed design, design check, and construction supervision of the Pont de Sèvres and Issy RER stations, the tunnel, and associated ancillary structures.

As a key player in the Grand Paris Express metro project, Ingerop is namely the lead contractor for the future Line 18, which will extend 34 km from Orly to Versailles. In addition to underground sections and buried stations, the alignment includes a maintenance center and a 13 km elevated section crossing a strategically important area of the Greater Paris region.

Line 18 will serve Paris-Saclay, one of the world’s leading research and development hubs. Through the various urban development projects linked to the line, Ingerop demonstrates the full range of its expertise.

Following an initial first framework agreement aimed at outsourcing the complete project management for certain overhead line rehabilitation and underground line construction projects, RTE, the operator of France’s electricity transmission network, is once again placing its trust in Ingerop’s teams by awarding them two new framework agreements:

• research and processing of declarations of public utility and agreements for HTB1 overhead lines, in partnership with SEGAT (subcontractor),
• complete outsourcing of project management for the construction or extension of certain Very High Voltage substations. Our mission notably includes civil engineering, high voltage/low voltage studies, and telecommunications networks.

This ambitious programme enables us to support RTE in the development and modernisation of its power grid for at least the next three years.

The project involves a dual extension of the Marseille tram network: 7.1 km to the north and 1.4 km to the south. This is a flagship project for the region, as it is set to provide high-capacity public transport to some of the most isolated and disadvantaged neighbourhoods in the northern part of Marseille. This project is part of the metropolitan area’s Urban Mobility Plan and aims to connect the tram network with several major traffic-generating hubs in the northern part of the city, as well as the future Saint-André railway stop planned as part of the new Provence–Côte d’Azur line (LNPCA).

With 60,000 m² of surfaces paved, over 2,300 trees planted along the route and the creation of 8 km of cycling paths, the project will also enhance the quality of life for Marseille residents by 2030. The project also includes the creation of 11 new stations in the north and three in the south.

As part of the project management consortium, Ingerop is responsible for part of the overall project management, as well as the engineering of the stations, road integration, mobility, road signage, low-voltage systems, and civil engineering structures.

Within the Bordeaux metropolitan area, home to over 800,000 inhabitants and with a limited number of bridges crossing the Garonne in its northern half, the creation of a cable connection would provide an effective solution to daily travel needs. An additional connection between tram lines A and B would thus be established. This mode of transport would guarantee users a high-performance service, with optimised investment and operating costs on this route, while minimising its environmental impact.

Since December 2024, the Ingerop teams have been supporting Bordeaux Métropole on this ambitious project with multiple challenges: climbing the hills on the right bank, crossing railway tracks, and spanning the Garonne River. It is on this last point that a technical challenge must be met to maintain the 53-metre clearance above the river; some pylons could reach heights of nearly 85 metres.

Ingerop’s mission begins with the feasibility study and is expected to continue through to commissioning and monitoring the start of operations (targeted for 2032).

In collaboration with Agence TER, Ingerop is designing the redevelopment of the Aire des Vents (seven hectares dedicated to Dionysian events) to provide Seine-Saint-Denis with its ninth departmental park, covering 27 hectares.

This project transforms the Aire des Vents into a large park focused primarily on sports and recreation, incorporating an ambitious depaving strategy. 57% of the seven hectares are being restored to
natural conditions, with a goal of zero rainwater discharge into the drainage systems. Biodiversity is enhanced through the planting of 8,200 trees and the creation of compensatory meadows to complement the existing woodlands. The developments include a 1.5 km cycling loop, a climbing block utilising the existing earth-reinforced noise barrier wall, as well as cooling areas combining water features, shading and natural meadows.

The project is based on a circular and efficient management of resources. Actierra supports this approach to circular economy and environmental resilience. The partial inauguration is scheduled for spring 2027.

Since 2022, in partnership with the Jacqueline Osty et Associés agency, Ingerop has been responsible for the design and implementation of the public spaces at the heart of the Part-Dieu district in Lyon.

The team designs the developments from a pedestrian’s perspective to create human-scaled public spaces. This second phase of the project also aims to create new rest areas and to develop livable public spaces in a sector with very high pedestrian and traffic flow.

The urban redevelopment studies incorporate a strong commitment to sustainable city principles, addressing depaving, heat island mitigation, circular economy, biodiversity, resource efficiency and urban nature in an integrated manner. The project involves complex construction phasing management with significant interfaces and very dense soft-mobility traffic.

By the end of 2025, the Bois de la Part-Dieu and the place des Martyrs de la Résistance will be delivered, providing a concrete example of the neighbourhood’s “landscape revolution.”
