Today's construction industry is facing a true paradox. Project owners are being asked to construct buildings that are increasingly complex and with higher performance levels. The apartment block, factory, warehouse, hospital, school or stadium of the future must be "smart", digital and fully connected. Yet, it must also be practical, completely safe, environmentally friendly, or even self-sufficient in terms of energy. Though, in the construction industry, traditional tools such as 2D drawings and hard copies are still widely used.

However, there is a very efficient tool, BIM (Building Information Modelling), which can optimise building design, modelling, construction, operation and upgrades. This high-performance tool is operational throughout the life cycle of your building, and will provide you a digital avatar, updated in real time. The avatar, which is based on the 3D model of the building, will be the tool that assists you for all the engineering processes. The use of a digitalised baseline is a true paradigm shift. Project owners now have a simulation tool they can use to anticipate their operational requirements, offering precious decision-making assistance.

10% of public organisations use BIM (Building Information Modeling) and 35% of building companies already use it (Building Information Modeling) Source - 14/03/2018

Our approach

Assystem is one of the pioneers that has made inventive use of BIM part of its daily work. Our approach is based on a BIM model and a BIM protocol. Data is centralised and shared in a single collaborative work tool.

Assystem uses the BIM approach throughout the life cycle of infrastructures:

  • in the design phase for preliminary detailed design and pre-overview, concurrent engineering and advanced functions (cost modelling, simulations, etc.)
  • in the construction and test phase for work phase overview, clash management and worksite planning
  • in the operational & maintenance phase for asset management and reverse engineering

The initial 3D model may be supplemented by scheduling (4D), construction costs (5D), sustainable development (6D) and building life cycle (7D) models.
