"La cité Musicale"

At the end of 2015, ACFT Bureau d'Études took part in a major architectural project: the opening of the Seine Musicale on Île Seguin.

At the beginning of the 20th century, Seguin Island was the symbol of the Renault car manufacturer with a state-of-the-art plant that produced the brand's iconic models: the 4CV, the Dauphine, the R4, R5, ...

L'usine Renault dans les années 50/60

In the 1990s, the plant was no longer adapted to competition and closed on March 31, 1992.

In 2010, the Departmental Council of Hauts-de-Seine bought for symbolic 1 € the third of the island to build La Seine Musicale.

The objective of this project is to accommodate all types of music with: an auditorium, a large auditorium, recording studios, ...

The overall silhouette of the project is reminiscent of a liner whose base tilts to let emerge the auditorium, a wooden nest woven with curved shapes. It is on this part of the building that the knowledge of ACFT Bureau d'Études was put to use.

The objective was to study the glassware of the auditorium and metal racks
to maintain them. This building has 14 rows of 42 hexagonal windows and 84 triangular windows. In addition, an additional difficulty is added to this project: each piece must be unique to give the desired appearance to the structure.

The challenge was successfully and quickly achieved thanks to a system for automatic generation of 2D models and 3D modification developed within ACFT Bureau d'Études. In order to make this system work, a 3D reference model had to be created first, and the system could then generate and modify new models according to the customer's wishes from this reference.

The project ended in June 2016 for ACFT Bureau d'Études.
The glassworks were laid in the second half of 2016 and the beginning of 2017.
As for La Seine Musicale, it opened its doors to the public on Saturday, April 22, 2017 with an inaugural concert of the Insula Orchestra, held in the auditorium, object of the performance of ACFT Bureau d ' Studies.
