The docks of Saint-Ouen are an old industrial complex developed around a port basin connected to the Seine river in the French town of Saint-Ouen-sur-Seine. Today, ‘Les Docks de Saint-Ouen’ refers to the 100 hectares eco-neighbourhoud being developed on the same site. Once completed, the Docks neighbourhood with its vast public spaces and extensive planting will offer housing to 10,000 people and is expected to create the same amount of jobs.
As part of the larger redevelopment scheme, two new commercial buildings offering various services such as office spaces, auditoriums, showrooms and gyms, are being erected in the Docks ZAC business area.
Because of line 13 of the Paris metro running underneath the two future buildings, the acoustical consultant advised to have them acoustically decoupled from the substructure by means of Stravibase Spring bearings.
The double nested structural spring bearings are designed to cope with a deflection variation during construction and deliver the required natural frequency of 3.5Hz, thereby guaranteeing proper noise and vibration isolation.
Given that the building stands on the banks of the Seine river, the risk of occasional flooding exists. The rise in water levels would put great pressure on the outer walls. To limit the horizontal displacement of the retaining pre-compressed horizontal Stravibase SpringBox bearings were installed as well.
