Vidago Palace, property of Unicer, is one of the most famous historic luxury hotels in Portugal. 100 years after it opened (1910) was target of a recovering of 48 million euros and the architecture designed by Ávaro Siza.
The building consists of six floors. The floor -1 for storage, changing rooms, the restaurant is on floor 0 with double height and the remaining floors are intended for the accommodation.
In the southern wing, the presence of the dining room, forced the adoption, in the upper floors of structure with function façade / façade having approximatdly 12m of span. Mixed beams are used with slabs of 15 cm thickness and HEB 300 profiles.
The coverage structure was executed in wood, using, in part, the existing (top) roof trusses and using the roof slab of the roof to eliminate lower risers. As far as the foundations are concerned two types of situations occur: progression in depth below the foundation levels and detection of pathologies related to settlement of the foundation soil that requires consolidation, in depth, using “jet grouting” columns in localized areas. In the general situation the ground floor and lintels proposed, connected to the base of the existing walls, ensure its proper performance.
The Project of Álvaro Siza only covers the reabilitation of the Palace exterior, the implementation of the new SPA and the recovery and adaptation to a new program of the Club House, the interior of the building and the park are not included in this project.
