France Outdoor Works:

• 18 km of High-Speed Rail Line.
• 2 flyovers.
• 42 Structures including 4 viaducts: over rivers, A9 Motorway and RN9 Highway.
• Punched Tunnel entrance to minimize « Sonic Boom » effect.

Tunnels:

Twin-Tube tunnel 8,3 km long, 2 x 50 m² finished cross-section with cross-passages every 200 m.

This stadium has a capacity of 20.000 covered seats, and stands in the inner city (in the middle of a park), as it is replacing the former Charles Berty stadium. This
stadium is multipurpose-capable: football, rugby as well as events. Supported by a metallic frame, the transparent and round shapes of the roof have been built with wood purlins and glass. It minimizes the visual impact of the building and smoothes its integration in the urban landscape.

Thanks to an inner technical ring and an outer architectural one, all the functional units are laid under the stands.  Included in the design is the possible extension of 10.000 more covered seats. It will be feasible, with the addition of a balcony. The stadium includes a 1000 places buried parking lot which allows preserving the external planted area.

Designed per High Environmental Quality standards, the stadium benefits special treatment regarding sound quality and noise protection, and features environmentally selected building products including 1000 m² photovoltaic roof panels. Finally, this project includes specific urban facilities such as service roads and the extension of the C tramway line.

The project includes a total floor area of 85,400 m², of which 26,500 m² are in superstructure and 58,900 m² in infrastructure and a car park of 550 places.

The structure required 34,400 m3 of concrete, 12,200 m² of masonry and 3,200 t of metal framework. The structure of the museum consists of two sloping ceilings and mezzanine floors of about 40 m wide and 250 m long, supported by bi-articulated metal “stilts”. The stability of both blocks of the museum is ensured by the concrete cores placed at the ends and the central metal pears. A 20 cm central expansion joint allows maximum non-throttled movement in case of emergency.

The roof of the museum, housing the restaurant and the library, consists of a deactivated concrete slab, accessible, of 10.000m² near the Seine and the Eiffel Tower.

The structure is protected against water ingress from the basement by a perimeter diaphragm wall with a maximum height of 30 m, recessed at its base in the sands of Bracheux and through a plastic clay layer thus forming a waterproof cap. All around, a clay merlon integrated into the landscape as well as the perimeter walls provide protection against a hundred-year flood of the Seine (with a security guard of 30cm).

A large 80,000 seat Stadium built in Saint-Denis Paris area. A large metallic cablestayed structure weighing 8,500 t. with 65 m. long cantilevers covers a 62,000 m² surface 10,000 m² of which are made of glass.

Ingerop is in charge of the BIM project management of lots 2 and 4 within an engineering grouping, for a 25% share of the fees.

The missions handled by Ingérop are:

• Design (feasibility studies, final design, assistance to the client at work contract phase)
• Supervision of the works
• Preparation of the environmental authorisation dossier
• Eco-design
• Project management (management of interfaces, costs, deadlines and risks, consultation)

The technical subjects handled directly by Ingérop concern:

• Layout of the canal and the restorations
• Earthworks (large earthworks) and related earth movement (problems of large earth surpluses)
• Engineering structures (canal bridges, bowstring bridges, double girders, PICF, etc.)
• Network re-establishment

BIM coordination

The city of Lille launched in 2007 a stadium project which would match the UEFA demands and which could also host various cultural and sports events.

Structure engineering of special structure: roofing, sliding roof.

Characteristics
Flexible performance venue,
The full stadium level reaches a height of 31m (101 feet) and has a total capacity of 50,186 seats including 4,965 business seats, 1,842 luxury-box seats, 448 protocol seats and 326 reserved for the journalists,
Enveloped by a translucent shell with rounded angles, the stadium has an immense luminous screen that forms its urban façade,
A movable roof consisting of two sliding panels enables the open-air stadium to be converted into an immense covered hall in 15 minutes,
HQE building with its solar panels and two windmills to ensure electrical supply,
Another arena, located under the movable playing field, appears as a prolongation of the stands.

Description

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.

Long of 13.9 km, 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.

As part of the road tunnel Safety measures, in accordance with Circular 2000-63, DIRIF has entrusted INGEROP for design and work supervision for the safety of the Champigny sur Marne cut-and-cover tunnel. This mission follows the definition of the improvement programme and elements of the Safety Dossier in 2003-2004.

CHARACTERISTICS

• Urban tunnel with 2 unidirectional tubes of 750 m and 780 m, with 4 lanes and high traffic, on the A4 motorway
• Works with maintenance of the operation
• Co-activity with 4 other transverse construction management on the site (supervision overhaul, DAI video and physical closures, self-evacuation, radio, etc.)

Civil engineering works:

• Emergency exits and new safety and fire niches creation
• Facilities for disabled people
• N2 or N3 fire protection of structures and networks
• Redevelopment of technical rooms and ventilation plants

Equipment works:

Sensitive environmental context (Gulf of Morbihan) requiring special monitoring by the Water Police and the Maritime Works Directorate.

The project consists in constructing a toll way that doubles up the existing congested A9 freeway over 19km near Montpellier. The main characteristics are:

• 3 lane divided carriageway running parallel to the existing A9 freeway over 10 km at the eastern and western ends of the project and running parallel to the proposed high-speed railway line over 8km,
• 1 system interchange at each end of the project with widening of the existing freeway (over 4km at each end),
• upgrade of Vendargues interchange,
• grade separation of local roads,
• rest areas,
• modification of the existing tell facilities.
