In Aubervilliers, the Hôpital Européen de Paris underwent an extension and restructuring; again, this was a complex project on a constrained site in a densely populated urban area.
The liquid oxygen that supplied the hospital before the works was replaced by two containers equipped with oxygen generators and positioned on the roof of the building.
These containers now supply medical oxygen to all departments and 265 beds. The space previously taken up by the slab dedicated to the liquid oxygen tank was thus reclaimed for the construction of a new building.
