The vertical connections of the building are guaranteed by two inner stairs bodies at the side of the room and by some stairs mostly for the service of workers and artists, situated in an autonomous space on the east front. The first two ones, symmetrical except for the adoption of the lift only for the stairs on the right, are realized in reinforced concrete with covering of natural stone treated with skidproof bushhammering. The lift is oil-pressured and suitable for disabled transport. The third stair, inserted in an autonomous stucture, as we've already said, is always in concrete, with covering in skidproof ceramic material, and it serves the levels of the changing rooms, of the stage, in addition to the dance hall and to the flies, also guaranting the access to the covering, where the main mechanical installations are situated.
The material of flooring and covering using for the services destinated for the public, will be in mosaic with tesseras cm. 2x2.
