Bouygues Immobilier becomes the first developer to develop all of its projects in 100% BIM

The objective initially set was for 25% of housing projects in 2022, 80% of projects in 2023 and 100% of projects under design in 2024. It was achieved, one year in advance, in 2023, illustrating the dynamism of the company in terms of innovation.

BIM is based on work tools and methodologies which allow the design and operation of a digital model by modeling all the plans of a future project thanks to an innovative collaborative approach. This allows the project to evolve based on the chosen data.

Bouygues Immobilier's transition to this model reflects the company's desire to respond relevantly to market requirements through a solution combining speed, efficiency and precision in the management of design data.

An evolution of the promoter profession which supports its entire ecosystem

Thanks to the generalization of this method, Bouygues Immobilier simplifies and unifies these processes, which allows for better productivity and more qualitative production in design. All stakeholders involved in a project (architects, project managers, construction companies, etc.) are now required to work together and in a coordinated manner using common software. This collaborative approach has the advantage of better quantifying the interventions of the different trades throughout the project and therefore reducing the associated costs, while guaranteeing quality.

“The evolution of the promoter profession is also accompanied by the evolution of its ecosystem. This is why we are proud to have succeeded in getting all of our partners on board in adopting this new working method,” explains Annalisa De Maestri, Director of the Digital Production Environment at Bouygues Immobilier. “In three years, we have trained more than 150 architects in this method,” she adds.

Technology at the service of environmental performance

From an environmental point of view, BIM also provides global visibility regarding the different performance indicators specific to each project. It is an effective tool to help manage the carbon trajectory of projects in the design phase because its use allows – among other things – to determine/optimize the choice of the most relevant components and materials to be integrated from one point from an economic and environmental point of view.

In the future, at each of the design stages, it will be possible to retrieve, with much more ease and fluidity, all the data to ensure that the CSR objectives set are achieved and/or to optimize them if necessary. So many elements which make it possible to certify the viability of a project and even to calculate its life cycle in the long term.

An approach that meets the requirements of communities and users

Thanks to BIM, Bouygues Immobilier is strengthening its agility and its ability to provide even more tailored responses to the requests made by the regions, thereby promoting the acceptability of its projects. This new approach is inspired by the working and data organization methods used in the industrial sector since, in practice, it allows Bouygues Immobilier to offer dozens of uses from a single modelization.

This process is facilitated by the provision of an internal library, updated daily, which allows architects to integrate design products designed to be adapted to the majority of projects. “The latter are designed like Tetris, which fit together with precision, which allows us to respond accurately to the requests addressed to us, despite the realities on the ground which sometimes require that the plans be reviewed/modified on request. last minute ! » confides Annalisa de Maestri.

In the era of customization and modularity, the generalization of BIM stands out as a major advance. It allows customers to project themselves by providing differentiation. “For a T3 it is now possible to offer up to 30 different configurations! Without BIM, this could not have been made possible without causing an explosion in costs and delays,” concludes the Director of the Digital Production Environment at Bouygues Immobilier.
