Cities & territorial development


Assystem accompanies public and private actors in the adaptation of urban and territorial infrastructures facing demographic growth and new ways of living.

Assystem accompanies public and private actors in the adaptation of urban and territorial infrastructures facing demographic growth and new ways of living.

Context and challenges


All over the world, numerous developments of urban areas or territories are necessary, whether to adapt to demographic growth, to improve the living standards or to develop new economic, tourist and heritage areas.

Our future living conditions will be strongly impacted by infrastructures built today and the way we design them. These changes are key to our territories’ future. They also need to be designed considering their significant impact on the environment and daily needs like water, transportation, sanitation, recycling, etc.

Supporting the growth of large urban projects

Over the next 100 years, the worldwide urban population is expected to double. Many large urban programs are being initiated around the world: these urban infrastructure and facilities development projects can be launched either as part of the renovation of existing towns or neighbourhoods or as part of the construction of new smart cities on undeveloped sites. These mega-projects require strong skills in urban planning and zoning to develop the required infrastructure, while respecting client expectations, the interests of all stakeholders, technical and environmental constraints, and local codes and regulations.

Supporting territorial development through the construction of sustainable infrastructures

Major territorial projects consist of a multitude of integrated sub-projects like the development of large infrastructures, public facilities, public utility networks, roads, bridges and many others. All these complex infrastructures must be anticipated and adapted to the specific characteristics of each region, according to local environmental, social and economic requirements and the objectives of the clients. Advanced expertise in feasibility studies, master planning, engineering and project management is a requirement for coordinating the development of infrastructures that will drive growth in the region.

Our expertise in Cities & territorial development


As part of a leading international engineering group in Europe, Assystem Stup has more than 60 years of experience in complex and highly regulated sectors. Assystem Stup’s skills in project management, industrial information systems and design are major assets for its clients (private and public sector) in territorial and urban development. Assystem Stup analyses and integrates all the specificities of each infrastructure, by leaning on its multidisciplinary and cross-sectoral expertise:

Cities and urban development: Redevelopment of the public space or conception of new urban zones, Assystem Stup emphasises at the same time the quality of the conception and a rigorous planning to assure the technical feasibility of the projects and their achievement in respect of the imposed requirements. The success of these multidimensional urban projects resides in the complementary nature of the teams’ abilities: analysis and preliminary study of the site, master planning, design, engineering, review and upgrade of norms/standards, management of the entire life cycle of the project… It is the combination of all these solutions that will guarantee the success of the project, while respecting the environment, society and the client’s specifications.

Territorial infrastructures: Thanks to its global Owner Engineer offer, Assystem Stup takes charge of large complex projects of territorial infrastructures on the whole life cycle. Thanks to the many years of experience of its teams, Assystem Stup supports owners, BOT operators and EPC contractors in the development of rural and urban road networks, motorway and expressways networks, large road and rail bridges (over rivers or air bridges in congested urban areas) or port infrastructures. To coordinate these types of complex projects, Assystem Stup can count on major assets in socio-techno-economic feasibility, traffic studies, prioritisation and master plans, detailed design, construction supervision and PMO.

Industrial and complex buildings:  Assystem Stup also supports many complex building projects such as hospitals, defence infrastructures, manufacturing sites, logistic or retail centres, and even stadiums.

Whatever the mission, Assystem Stup offers its customers a variety of solutions: site characterisation, environmental and impact studies or geosciences to assess local regulations and ensure that projects are brought into conformity. Additionally, Assystem Stup manages projects using cutting-edge digital solutions, making it possible to anticipate decisions during the design phase and to ensure the performance of the architectural and technical design of infrastructure and public equipment.

In a constant search for solutions that favour sustainability, Assystem Stup also participates in territorial development by promoting the utilisation of low-carbon energy options: nuclear, renewables,  and hydrogen.
