Structures, underground works and geotechnical engineering are areas of construction where risk control requires calling on the best specialists.

Geological studies and prescriptions and geotechnical, to the design and management of master pieces, of tunnels or dams, IDCG favors a global and multidisciplinary approach to the project in a constant optimization of its technical, economic and environmental performance.

Our numerous establishments in Africa and abroad guarantee an effective proximity with our customers and an understanding of local issues, particularly in the environmental field.

For 20 years, IDCG has been developing its know-how in all disciplines of geology, geotechnics and materials, in the fields of linear infrastructures and complex civil engineering and building works.

More than 30 specialists are involved in the following services:

• Geology and hydrogeology
• Design of structures
• Soil / structure of earthworks
• Earthworks geotechnics
• Materials engineering and laboratory testing
• Instrumentation of structures and sites
• Pathology of structures
• Natural hazards
• Geophysics

IDCG’s expertise in soil and material mechanics is reinforced by its high-performance technical means in calculations (3D finite elements in soil and rock mechanics), from a laboratory accredited by ISO / IEC 17025: 2017 (E) for tests on soils, rocks, concrete, cements and pavement materials and on means of instrumentation and auscultation methods (sensors, static or dynamic measurements).

The reputation of IDCG’s Structures teams has grown over the years and benefits from the capitalization of significant experience (more than 100 m² of structures studied) and the involvement and motivation of its new generations (more than 30 experts).

IDCG is involved in all phases from design to operation of structures, with an integrated and multidisciplinary approach to projects (geotechnics, environment, structures, expertise, etc.). The group relies on teams of engineers and experts passionate about their profession and keen to serve its customers.

IDCG designs both current works and exceptional works.

The current structures are bridges of relatively modest size and of usual technicality which mainly fulfill functional objectives. Their large number has enabled IDCG to standardize their design and develop suitable and economical industrial processes.

Over the centuries, and particularly in the 19th and 20th centuries, the daring of achievements has often gone hand in hand with the mastery of new materials. From a purely utilitarian structure, the bridge is increasingly becoming a work of art and a work of architecture marking the environment and the landscape.

Yesterday like today, the IDCG teams have designed many structures that are the source of major innovations that have changed bridge design techniques.

IDCG works on all types and types of structures: reinforced concrete, prestressed, steel, composite, wooden or composite structures; girder bridges, box bridges, arch bridges, bridges with extradosed prestressing, cable-stayed or suspension bridges, movable bridges. Its missions focus on

• The design and execution phases of new structures
• Expertise, repairs and maintenance of existing structures

• Tunnels and underground structures: IDCG among the world leaders

• Safety in tunnels requires an increasingly complex “system” approach, with a very strong interaction between geology, civil engineering, equipment, ventilation, safety and operation.

• Their design requires a great deal of experience in each of these specialties and an ability to manage, with a transversal approach, all the technical and temporal interfaces.

• IDCG supports you for all your underground works projects (drilled tunnels, covered trenches, underground cavities), whether they are located in urban or rural areas, whether they are road, rail, metro, ‘sanitation, underground storage or underground parking lots.

• The missions carried out by the IDCG teams cover issues of equipment, safety / operation, fire, renovation, and tunnel ventilation.

Why choose a general practitioner or a specialist when you can have both?

The Council by IDCG puts the diversity of its talents at the service of your projects, excellence in addition.

Our commitment is made of creativity to overcome all challenges and innovation to build together a bright future.

All the expertise in mobility and the sustainable city:

An ecosystem of specific and complementary skills to master with agility the major challenges of tomorrow.

Our 30 consultants are proud to support and bring to fruition unique projects that have meaning for them, for you, for everyone.

IDCG designs, supplies, integrates and puts into service equipment and turnkey operating systems for the optimized management of its infrastructures.

Thanks to its experience as an operator and the technical know-how of its engineering companies, IDCG designs tailor-made solutions optimized for each turnkey project by committing to the price, lead times and performance of systems.

Motorway operating equipment more particularly includes: toll, telecommunications, traffic management and user information equipment and systems, signaling, emergency call networks and tunnel equipment.

Airport equipment includes, in particular, security and access control equipment, information systems and airport baggage handling systems.

IDCG also offers turnkey solutions in the energy field: production of renewable energies, smart electricity grids, rural electrification and district heating networks.

Urban transport

IDCG, a unique know-how at the service of urban transport projects

IDCG brings together all the skills in the service of various modes of guided urban transport: heavy metro, light metro, high-capacity tram, economical tram for medium-sized cities, people mover, urban cable transport, etc.

IDCG has unique know-how for the development of transport systems: from design to construction, we work as an assembler for the realization of your urban transport projects.

Recognized skills in studies, civil engineering and systems, brought together in multidisciplinary teams that contribute to our added value.

For IDCG, each city is unique and has a different relationship to its transport. Our teams support your decision-making by offering you tailor-made solutions.

Urban transport is an important lever for Climate Plans and regional sustainable development projects. At-Beyond the public transport aspect, they encourage the requalification of major axes, the improvement of the quality of public spaces and soft modes, thus contributing to the revitalization of local shops.

This is why IDCG integrates eco-design at the heart of its projects, from the upstream phases.

IDCG has expertise in a wide range of urban transport : Bus Rapid Transit, vice (BHNS), Rails, Taxis Mini buses etc.

For all types of urban transport designed and implemented, we integrate all of our skills in the service of your projects from upstream, for the choice of the most suitable mode, until their completion. IDCG masters the different trades involved in your projects: systems, building through viaducts.

IDCG is developing numerous urban transport networks in project management and project management assistance by recommending suitable modes.

The city of tomorrow, as we conceive it, is a city that integrates the challenges of the triple demographic, energy-ecological and digital transition that the world is currently experiencing.

Through its size, its history, its multiple skills, IDCG provides its public and private clients with value-creating solutions up to this triple transition.

In developing and emerging countries, more than two billion additional inhabitants are expected in cities by 2050, with the aim of improving living conditions for all. In developed countries, the aging of the population is another major phenomenon of the 21st century which also impacts city life.  

The scarcity of natural resources, transport congestion and global warming are all phenomena that raise many challenges on an urban scale. The need to design, manage and renew sustainable and resilient cities that minimize carbon footprints and adapt to climate events is emerging at all latitudes.

Digital technologies and connected objects are giving rise to new services and new uses in cities. All stakeholders are concerned : residents, visitors, businesses, public services and private operators.
