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.

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.

Our Approach

The city of tomorrow cannot be designed ex nihilo. Its engineering is based on the shared identification of its strengths and weaknesses, on an adapted and adaptable, integrated and reasonable design, and on an achievement that meets the ambitions and resources of our customers.

For each of your projects, we are committed to supporting you in an approach that is both tailor-made and multidisciplinary.

A design and construction techniques adapted to local specificities, whether environmental, financial, economic, social, cultural or regulatory.

We mobilize a team with a fair balance between local know-how and expertise and

International thanks to a judicious selection of our partners.

Our difference comes from our ability to use our skills in engineering, project set-up and operation to define urban projects including transport infrastructure and urban services.

Our key principles

Anchored in adapting to local issues and mobilizing good expertise, we design urban projects based on 5 key principles.

Optimizing the attractiveness of a project from three angles:

  • economic, to attract investors and businesses
  • social, to bring in new inhabitants, visitors, tourists, etc.
  • environmental, to develop biodiversity, ensure sustainability and limit negative impacts

Innovate in all components and all phases of the project:

  • project set-up: search for the best arrangements in terms of governance, risk and contractual strategy
  • design, construction and operation: use of design methods and innovative technical solutions (3D design, BIM, mobility models, energy models, participatory studies of the living environment, etc.), new mobility and sustainable energy services

In particular, new information and communication technologies are giving rise to new services and new uses in cities. All the actors are concerned: inhabitants, visitors, companies, public services and private operators… The developers of such solutions speak of smart city orsmart city.

Minimize the carbon footprint of the project and its impact on the environment in general. Following the paris agreement during COP21, the objective of limiting the increase in temperatures to 2 ° C and ensuring, at the level of states, “net zero emissions” by 2050, implies immediately including mechanisms reduction or compensation of emissions during the design of our projects. More generally, evaluating the cost / benefit impact of solutions limiting GHG emissions and the consumption of resources or space is at the heart of our approach to urban projects.

IDCG emissions, the consumption of resources or space, is at the heart of our approach to urban projects.
