25 years after the machinery of the Renault factories at Boulogne-Billancourt was forever muted, the music comes back to the Seguin Island. La Seine Municale, the new cultural facility of the Hauts-de-Seine district opens with Bob Dylan’s inauguration concert on the 22nd of April 2017.
Executed as a PPP (public-private partnership) between the Hauts-de-Seine local authority and the JV led by Bâtiment Île-de- France, the Seine Musicale’s objective is to become an internationally renowned cultural stage.
Built in the tip of the Seguin island, the main building was designed by the Japanese architect Shigeru Ban, Pritzker Award 2014, is 280m long and hosts two concert halls.
The entire structure is founded over 800 piles, up to 22m deep.
The auditorium with 1,000 seats is destined for classical music. Its façade comprises a timber free-standing mess, covered by 4,000m2 of glass with a 1,000m2 “veil” made out of solar photovoltaic panels rotating on top of it, chasing the sun.
The bigger music hall is destined to the modern amplified music. Thanks to its retractable terraces, its capacity ranges between 4,000 to 6,000 seats. It is covered by 60m span steel frame with a weight of 2,500 T, that at same time bears a Japanese garden. From the tallest accessible point, you can enjoy a panoramic view 36m over the Seine river.
Member of the Design and Construction Full Project Management JV in charge of the structures design: preliminary and detailed design and works supervision.
Setec undertakes additional services for the counter-calculation of the timber mesh as part of the validation of the contractor’s sub-consultant’s works execution design (SJB). The initial geometry designed by the architects is exported by the 3D software Rhinocéros© and imported in the finite elements analysis software Pythagore©, in-house developed by setec tpi. The geometry is then loaded, including the results from the wind-tunnel tests undertaken in the CSTB in Nantes.
