n/a IDCG has twenty-two (22) years of leadership in the road sector in Southern and Eastern Africa and internationally. It is the group’s leading business in terms of volume of activity. The group provides you with all the skills on all road-related themes, from setting up projects to operating networks. Its size allows it to tackle large projects and adapt to increasingly tight deadlines. Thanks to its level of expertise, IDCG has the capacity to carry out exceptional works, such as the New Highway from Kampala-Busega to Mpigi in Uganda. The road is one of the areas where IDCG innovates the most and develops unique tools to help you achieve the objectives expected today on infrastructure projects: these must be safer, more readable, more respectful of the environment, particularly in Southern Africa where upgrading the aging road network is a major challenge. In the ten or so countries where IDCG is established, the modernization of networks or the creation of new infrastructures are also essential steps for the development of a large number of regions. For all the projects that you entrust to us, the group relies on its permanent capacity to innovate to reduce the ecological footprint of the routes, promote their landscape integration, take into account societal issues, develop inter-modality, improve service to users and road safety, without forgetting the essential issue of safety on construction sites. The digital model at the service of infrastructure projects. In order to optimize the execution times and the quality of projects, in the studies and works phase, IDCG is a pioneer of concurrent engineering in infrastructure projects. He actively participates in research projects for the development of BIM in infrastructures at the African level, two driving projects in the development of the interoperability of the data necessary for the multiplication of digital exchange platforms.
The last decades have seen the rapid development of information and communication technologies and their application to transport (ITS), opening up new perspectives in terms of mobility. IDCG closely follows these developments and is part of various working groups bringing together construction and transport stakeholders to define priority research axes, intended to maximize research and innovation within the African Union.

Road safety has long been a major concern for the group.

Recently, within a PIARC (World Road Association) technical committee bringing together road safety experts, IDCG participated in the development of a best practice guide for the design of safer roads.

This guide takes the human factor into account in its recommendations: useful for understanding difficult design areas, this study is intended for interurban roads where the most accidents occur, but also for highways and urban roads.

IDCG is also competent in the field of road operation and maintenance: the group operates and maintains roads or highways in 15 different countries across Africa.

In recent years, the taking into account of sustainable development has been approached in a global manner on all our road projects, whether it concerns design or work monitoring. Guidelines as important as the preservation of the resource, biodiversity, the overall cost of construction with its use and the influence on the economy of the territory or the intermodality of transport modes are at the center of our concerns. 

For more than 20 years, IDCG has provided its expertise throughout the life cycle of the project to operate and maintain major structures, road infrastructures and tunnels. IDCG has also developed a unique experience in the operation of motorway tolls integrating all means of payment: cash, bank card, and especially electronic toll (electronic toll), with or without barrier (“free flow”). These infrastructures are operated through long-term contracts, either as part of a PPP or concession, or as part of service contracts with a public authority. IDCG deploys innovative services in ecology, asset management and digital technology in order to optimize the management of infrastructures, the sustainable development of territories and the common interest. IDCG operates and maintains 44 roads and highways in 20 different countries, or nearly 4,400 km traveled daily by 3,500,000 vehicles. The group has a strong expertise in tunnel operation with a total of 81 km of tunnels operated. Our expertise in road operation and maintenance Our subsidiaries bring together more than 80 people, including many experts, working in the various fields of road operations:
    • Complete toll management (manual, automatic and electronic)
    • Development and implementation of trade policies
    • Management of electronic toll customers
    • Security and traffic management (24/24 supervision, patrols, incident response)
    • Tunnel operation
    • Management of major works
    • Viability, including winter

n/a

IDCG has set up with its operating subsidiaries a network for exchanging expertise and best practices (through its “Exploitation Club”).

The quality and performance of operations are regularly audited to ensure safety, optimal service levels and good management of the infrastructure.

A company policy is deployed in the subsidiaries in terms of health and safety, human resources development, environmental performance, operational excellence, innovation and risk management to share best practices.

Our Solution

A complete range of dedicated solutions is developed with the operating companies in order to continuously optimize the operation of the infrastructures.

  • IDCG Africa’s services in urban development are carried out on several scales of development, from regions, cities, to rural areas.
  • IDCG’s multidisciplinary teams in Africa are mobilized within the framework of urban development projects, and include road engineers, civil and building engineering, environmentalists, topographers, hydrologists, geotechnicians, socio-economists, etc. IDCG has at its disposal all the skills necessary for urban and regional planning.
  • Urban planning is at the heart of development strategies in Africa. IDCG supports public order givers, urban communities, organizations under supervision, etc.) and institutions.

Our teams ensure smart designs and manage all aspects of the layout and planning of urban spaces.

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 masterpieces, 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.

The structures are designed to reduce the impacts on the natural, physical and human environments (crossing a valley, covered trench in an urban environment, etc.). If they consume resources and energy, we implement an eco-design approach based on research, LCA (life cycle analyzes), experiences in various contexts. This approach makes it possible to reduce the ecological footprint of structures, while maintaining their functionality and relevance.

The geotechnical study also makes it possible to optimize the project in terms of material consumption and thus contributes to the achievement of one of the major objectives of the profession by 2020: to re-employ or recover 100% of the natural geological materials excavated on the sites, without any external contribution.

Environmental and social impact study

IDCG is approved in Africa by different Ministries of the Environment, Nature Protection and Sustainable Development (MINEPDED) to carry out Environmental and Social Impact Studies (ESIA).
The ESIA is a systematic process intended to identify, predict and assess the effects of projects on their biological, physical and social environment.
In the practice of ESIA, the focus is on preventing, reducing or compensating for the adverse effects of the project. The ESIA therefore aims to propose corrective actions to avoid, mitigate or compensate for these harmful effects on the environment.

Thus, all the ESIAs carried out by IDCG consider the specific context of each project and take into account the nature of the work to be carried out. With this in mind, when carrying out the ESIA, our experts deploy a rigorous methodology to:

  • Identify the elements of the biological, physical and social environment that will be affected by the project and for which an ecological and / or public concern is manifested;
  • Analyze mitigation measures, monitoring, budget requirements and possibly capacity building requirements;
  • Propose measures to improve, reduce and eliminate these impacts;
  • Propose accompanying measures with a view to improving the living environment of neighboring populations;
  • Identify the people affected through their private or socio-collective properties and propose a Compensation and Resettlement Plan if necessary.

This whole process makes it possible to:

  • Provide decision-makers with information on the consequences of the planned activities for the environment;
  • Promote sustainable development by taking appropriate reduction or enhancement measures.

To make development sustainable, the burden of environmental impacts must be reduced. These impacts are more complex, more important by their scale and have heavier potential effects depending on the complexity / specificity of the project and the sensitivity of its setting.

This is why the ESIA is of fundamental importance in development decision-making.

In many projects, this process also serves as a planning tool to promote sustainable development by integrating environmental considerations.
