Digital Modelling:BIM for a Better Managed Site
An indispensable tool in the construction sector
In the early 2000s, convinced of the necessity of designing, building, and operating buildings more reliably, faster, and at a lower cost, we started giving serious consideration to BIM (Building Information Modelling), which provides digital modelling and the management of the data within it. The principle is to use 3D technology to show all of the information that is useful for the design and construction of a building, and to simulate its behaviour. Soon, digital modelling will be 100% integrated, so that all participants in a project can work on the same model in real time..
We have already noticed the immediate benefits of this system by using it on many projects, including the Surrey Hospital in Canada, the Paris Philharmonic, the Abidjan Bridge and the Singapore Sports Hub. For the Sports Hub, we used digital modelling to model every element of this vast complex, such as the framing and the structure of the aquatic centre. All of the digital models were then assembled to obtain a general model for optimal coordination of the project.
A better understanding of each site
The concrete visualization of future buildings that digital modelling permits provides a better vision of the tasks to accomplish, and ensures good coordination between participants inside and outside of the company. In the end, sites are better organized, so construction times are shorter and less costly. Very concretely, 3D modelling makes it possible to anticipate and resolve increasingly complex construction issues that are hybrid, modular, and changing. For example, in developing the Paris Philharmonic, using digital modelling was a way to avoid 90% of phasing problems before work began on the site, such as the order in which the beams were to be installed. Likewise, during the design process for the Singapore Sports Hub, digital modelling allowed us to coordinate technical networks with structures provided by architects and design offices, revealing interferences that would not have been detected in 2D.
Advantages for everyone
Whether it be for customers, future residents, or site workers, digital modelling is an exceptional chance to better visualize the future building and get an overall understanding of the project, during the entire lifespan of the building. On sites whose organization is completely planned, the exact cost is known ahead of time, and the information necessary to its production is guaranteed to be consistent. After the building is delivered, BIM is a valuable tool for optimizing the management of an asset and facilitating the future development of the building. With its augmented reality and virtual reality features, BIM is now automatically included in all of our sales offers.

BIM has considerable benefits for everyone, enabling buildings that of a better quality, are more environmentally friendly, and are easier to operate, for the same cost or less. Everyone who has put in the effort to use it has continued to do so.
