Building Information Modeling (BIM)
As project management assistant (AMO), Equans Digital, an Equans France entity, has been supporting Société des grands projets since 2021 in strengthening the maturity of all Building Information Modeling (BIM) players.
In addition to this strategic oversight mission, the entity is also actively contributing to the implementation and operation of BIM at 15 stations and 24 ancillary structures on the Grand Paris Express.
The stations concerned include Roissy CDG Airport (+7 ancillary structures), Triangle de Gonesse (+5 ancillary structures), Saint-Maur - Créteil, Saint Denis Pleyel (+4 ancillary structures), Champigny Centre, Bagneux, Fort d'Issy Vanves Clamart, Gare d'Issy RER de la L15 sud, Noisy - Champs (+2 ancillary structures) and 5 metro stations on line 14 south, including Gare du Kremlin Bicêtre, Chevilly 3 communes, Porte de Thiais, Maison Blanche Paris XIII, Pont de Rungis (+11 ancillary structures).
BIM, an innovative approach to project management
BIM (Building Information Modeling) stands out as an innovative approach to project management based on the use of intelligent digital models for the entire life cycle of a building or infrastructure.
As part of the Grand Paris Express project, it is an invaluable ally for Société des grands projets in optimizing the design, construction and management of the new metro lines. The GPE is a technically complex project, due in particular to the urban density and geological constraints of the Paris region.
BIM makes it possible to centralize all technical information in a 3D digital model, facilitating coordination between the various players involved in the project. This scalable model integrates precise data on each element of the infrastructure, making it possible to anticipate potential problems and better plan interventions.
With BIM, the client can ensure optimum collaboration between the various trades involved in the project. Engineers, architects, project managers and other partners can access the necessary information in real time via a common platform, reducing the risk of errors, delays and additional costs.
It also enables information to be continuously updated, ensuring consistency throughout the project. By facilitating more precise management of both human and material resources, BIM enables rigorous work planning. Simulations based on digital models help to assess the impact of each decision, optimize construction times and reduce inefficiencies.
During the construction phase, BIM continues to be used to improve efficiency, coordination and monitoring, enabling Equans France to keep to schedule while guaranteeing the quality of the work.
When it comes to on-site coordination, digital BIM drawings can be consulted on site via tablets or laptops, facilitating communication between field crews and design teams.
The BIM model is regularly updated to reflect the actual progress of the work.
This makes it possible to track deviations from the planned schedule (4D modeling) and adjust plans accordingly.
Finally, changes occurring during construction can be integrated directly into the BIM model, enabling plans and quantities to be updated instantly.
Once the infrastructure is in place, the BIM model continues to play a crucial role in operation and maintenance.
It incorporates all modifications made during construction and becomes a digital mock-up of the building's actual state, useful for facilities management.
Information on materials, installed equipment and maintenance manuals is integrated into the BIM model, facilitating the management of repairs, interventions and replacements.
And when a building needs to be modified or extended, the BIM model serves as a reliable basis for simulating future work, facilitating the integration of new elements into the existing project.
BIM contributes to project sustainability by enabling better resource management and energy optimization.
For example, energy simulations based on BIM models make it possible to design infrastructures that are more respectful of the environment, by reducing the carbon footprint of construction and operation operations.
In short, Equans France's use of BIM for the Grand Paris Express and Société des grands projets represents a significant step forward in the management of large-scale infrastructure projects.
In summary, Equans France's use of BIM for the Grand Paris Express and Société des grands projets represents a significant advance in the management of large-scale infrastructure projects. This innovative approach not only enables more efficient execution of the work, but also ensures optimum long-term management of the infrastructure, in line with the project's performance and sustainability objectives.
