When reflecting about the City of Tomorrow, we often see images of hi-tech buildings, hi-tech infrastructure in a new city. However usually we do not start from scratch. We often start from existing cities that will evolve through a transition process to more sustainable and smarter cities.

Technology is an important enabler in this process, though not the driving force.

Our modern cities are characterized by growing diversity. The individual needs and priorities of people, living and working in those cities, will be the driving force in this transition. The city of tomorrow will thus be defined by individual needs and priorities; by choices related to living and working, need for open space, fresh air, health, services, recreation,…  

Only by realising quality projects, usually with a high degree of participation of the different stakeholders, our cities can evolve towards more sustainable and smarter cities.

Quality projects are those projects that are seeking and respecting a correct balance between social, economic and environmental parameters. 

A modern, international engineering & consultancy office, like Tractebel Engineering, needs to have specialists in all these fields to address to the complexity related to the realisation of projects in today’s context.

Therefore Tractebel Engineering values the diversity of education of her collaborators. Between our collaborators we have engineers, but also urbanists, architects, sociologists, economists, policy advisors, mobility specialists, water consultants, biologists, geologists,… who make the difference.

Another trump of Tractebel Engineering is the unique combination of an in-depth expertise in Infrastructure with an outstanding expertise in Energy. In a future where energy production and storage will become more and more decentralised, thus integrated in infrastructure, the combination of both expertises might appear to be a real asset.  

In the City of Tomorrow different themes play an important role.   




  • Governance


    The public sector has an important role in matching good governance with the individual needs and priorities of the people living and working in the city. It also has the important task to bringing the different stakeholders in this process (investors, architects, urbanists, engineers, consultants, civilians,…) together to come via a participation process to supported quality projects.

  • Mobility


    To organise sustainable mobility a number of disciplines are called upon. The areas of activity of our traffic management experts include town-planning, policy-making, traffic technology and traffic management design, multimodal transport models and operational micro-models. It involves an intensive process of interactions.

  • Environment


    It goes without saying that water plays a vital role in our daily lives. The ecology of seas, estuaries and rivers is extremely vulnerable. Technum call upon its 30 years of expertise in the water and environment sector in areas such as assessing flood risks, hydraulic modelling, coastal protection, risks of silting up etc.

  • Buildings


    In close collaboration with architects and our customers, we develop buildings that are conceived to satisfy their current and future requirements. We focus on the complete lifecycle: building and operating costs, energy consumption, as well as recycling at the end of the installations’. This approach complies with the most stringent regulatory and environmental provisions. 

  • Energy


    Globally we are facing the dillema of soaring global energy demand and the need to preserve precarious resources. Consequently, our goal is to achieve a sustainable energy solution that meets both our client's need and the environment's, well into the long term.

  • Communicatie


    Across all sectors, be this engineering, communication, media, healthcare, retail and manufacturing, we are increasingly seeing the use of digital technology. It is important to understand and appreciate the factors that are ushering in such changes and how these are impacting the modern day business.

    Mobil2040 is a visionary study Technum did at the request of the Brussels Capital Region. Rather than seeing mobility simply as a technical problem, it should be considered as a lever for change. Mobil2040 is thus about more than just roads, cars and metro lines. It also considers walking and cycling, work patterns, mental shift, new technologies, urban planning, citizen participation, our relationship with time and our living environment.

    AG Real Estate and GDF SUEZ Group are building the new GDF SUEZ headquarters right next to Brussels North railway station. They will provide a workplace for more than 3,100 staff currently working at various sites. The new building will become a benchmark for sustainable development and energy efficiency (E62 and K38 levels for the Pole Star building). The new headquarters, designed to comply with HQE and BREEAM certification, will provide office space of 75,000 m², an auditorium accommodating 300 and a restaurant catering for 700 people.

    The purpose of the project which involves resizing the River Lys crossing through the city of Courtrai (Belgium) (“Leiewerken – Doortocht Kortrijk”) is to expand and deepen the Lys, and also raise its bridges and make three major adjustments to the river’s course. Technum is carrying out the study on the various bridges, the development of the surrounding area and the quay walls.
