The new C.A.P.I., to be built inside the Regional Civil Protection Centre of the Umbria Region, will consist of 2 distinct, adjacent buildings, with different planimetric dimensions but of equal height; one for functions such as offices and dormitory of 500 square metres, the other for warehouse use, for a total area of 3700 square metres. They will be provided with independent accesses, pedestrian areas (pavements) and an area for systems (including an underground water storage tank for the fire-fighting system and a dedicated technical room on the surface). Finally, an artificial reservoir is planned for the temporary collection of rainwater from the warehouse roof, to be located in a peripheral position with respect to the intervention site. The structure of the entire building will be of the prefabricated reinforced concrete / prestressed concrete type, except for the foundation works, the body housing the stairway / lift shaft and the underground fire-fighting basin, in reinforced concrete to be cast in situ. In accordance with the provisions of the C.A.M., the permeability of the soil was taken into account, i.e. external draining cement slab paving was adopted, to be laid dry on a special foundation. In order to give the entire building a pleasant external appearance, despite its industrial and purely functional vocation, and in consideration of its rather low cost, it was decided to use fibre-reinforced cement slabs to be painted in different colours. Finally, the interior spaces of the office/dormitory building have been designed to communicate in a simple and intuitive manner the succession of spaces that will be located there, through the use of iconography and signs that will also decorate the spaces. Access to the office/dormitory building will be on the north/west corner of the building. Here, a glass wall will welcome the user into the entrance reception area, from which a large double-height connective space, illuminated by skylights on the roof of the office/dormitory building, will also function as a refectory. The connective space will flank the double rooms on the ground floor, with a dedicated bathroom and generous windows facing outwards, some of which are equipped with drop-down window modules, the workshop room, also with windows, and the changing rooms (one for each sex) with attached floor bathrooms, also for the disabled. The sorting corridor ends by accessing the staircase/elevator block. Here a hallway, with two exits to the outside to facilitate the outflow of users in the event of an emergency, will face the staircase ramp, the lift shaft and the laundry room on one side, and two storerooms and the floor technical room on the other. Access to the first floor will be via both the staircase with cantilevered steps and glass parapet located at the main entrance near the reception area and via the staircase/elevator shaft. Thus, the cantilevered staircase will accompany the user towards the relaxation area located above the entrance reception area and then along the gallery overlooking the dining room located on the ground floor. The gallery will be the connective space from which to access the offices, each equipped with 4 workstations and generous windows with views to the outside, some of which are fitted with drop-down windows.
