Álvaro Siza, Santo Tirso, Portugal, 2011
The facilities of the volunteer fireman of Santo Tirso come from the need to address the lack of functionality that had the old fireman headquarters. Opened in 2011, is a work authored by Alvaro Siza Vieira, estimated at 1,1 million euros. It has an area of implementation of 3800 m2.
The Headquarters consist of three bodies: the first body has three floors and one is buried. The second body is intended to workshops and the last body, corresponds to the tower (Home School) of firefighters. From the standpoint of implementation, has a circular shape and has a height of about 8.30 meters above the ground floor slab. The majority of walls and concrete slabs have a 20cm thickness each; except for those who are buried with 25cm and those that support the roof slab of the car park which has 30cm.
In car park we had to use the mixed slabs solutions with sections of HEB 700, embedded in a section of traditional concrete to protect them from the corrosion and fire.
In the body that corresponde to the training stairs it was adopted a solution of concrete slabs 35cm thick, Encastradas in the center (circular with 20cm thick) and supported in the outside in amounts of the some material
