Buildings & Infrastructures


Globally, urbanisation of our population is increasing at the rate of 200,000 people per day placing huge demands on housing and city infrastructures. In the next 100 years, urban populations are predicted to double in size. With a population of around 8-9 billion, the future of the way in which we live will be heavily influenced by what we build today and how it is designed.

With the advent of smart city thinking, buildings must be designed to fit into a larger and more coordinated vision in terms of energy consumption, workplace optimization and security. The design and content of tomorrow’s buildings will be just as important as systems engineering and traditional building construction.

Operation of buildings

Adopting smarter working to reduce construction costs and improve the operating performance

The operation of buildings needs to be integrated and anticipated to ensure optimum performance is achieved. Developing digital tools to evaluate the impact on the operation phase is a major challenge. As 70% of the operating costs of a technical building are set in the conception choices defined during the design phase (regardless of the quality of operation), it is crucial to foster installations which are easy to pilot with reliable control systems to serve the performance analysis of the building.

Buildings and infrastructures BIM

Adopt a cooperative approach for more effective and user-focused project management

The wide variety and highly technical nature of requirements for buildings and infrastructure projects, whether it be regulatory or functional, means that effective management is vital. This ensures that complex projects are focused on the user and the needs of the project owners. Building Information Modelling (BIM) tools for digital design and coordination, act as both a database and interface, making project management a cooperative process between teams working towards the goal of optimised construction and operational performance.

construction safety

Rising to the challenge of security issues to ensure site protection and personal safety

In a climate of constantly tighter regulatory constraints (personnel safety and environmental protection) as well as increasing exposure to physical threats, security has become a key issue in building design and construction. Systems must be designed to incorporate adequate protection to safeguard the buildings integrity and that of its users in the event of malicious attacks or extreme natural events.


As an international engineering group and one of the leading engineering consultancies in Europe, Assystem has over 50 years of experience of working in complex and regulated industries.

At the high end of infrastructure development, using its track record in project management, industrial information systems and design, Assystem supports both private or public sector owners and contractors including Defense, Education, Retail, Governments, Healthcare Industries.

Assystem examines and integrates all the specific features of each infrastructure, using its multidisciplinary and multi-sector skills:

  • A built-to-requirement design and construction phase for buildings and infrastructures, in particular with utilities for the specific processes and interface of each infrastructure.
  • Operational requirements and the associated regulatory compliance taken into account, analysis of risks, containment, explosion, fire.
  • Highly-specialised technical skills required in certain sectors, high-voltage electricity, HVAC and confinement, seismology and structures, lightning protection, safety notices.
  • Work projects completed at occupied and operational sites, in particular for heavy industries with high safety risks or establishments open to the public (service, rail transport).
  • Environmental concerns taken into account for industrial and defence sites, in terms of safety, access and protection against malicious acts.
  • Digital and robotics service solutions deployed to meet the new needs of Operators of Vital Importance (OIV), in particular for hospital structures, by guaranteeing security for people, assets and information.
