The hospitals of the future are digitised, innovative, and process-optimised, in some cases through the growing use of artificial intelligence. Accordingly, the energy distribution systems in hospitals are subject to high requirements. A large number of components, switching systems, and power distribution systems need to be housed and carefully protected.

That was the case in this project. The available space in the entryway area was ideal to store a large number of data distributors.

Therefore, a “room in room” solution was planned with a back wall and ceiling, incl. multiple cable bulkheads. The existing system partition wall could not be used in a structural solution since it was designed without a fire protection classification (F0). Therefore, only a four-sided room solution was considered.

Three large-format, dual-leaf inspection closures were used to ensure optimal access to the data distributors. The modular design allowed for quick and almost dust-free installation during ongoing operations.

The existing tile floor inside the room was then filled and smoothed on site.

Another bonus of the room-in-room solution was the finished, easy to care for surface, which required no filling, painting, or wallpapering work.
