Technical Data


The German real estate asset manager, TRIUVA, promoted in 2016 the development of a rehabilitation project for the building of its property located in Serrano 90 (Madrid). MC2 is then incorporated into the design team, led by RCCyP Arquitectura y Planeamiento, for the design of the rehabilitation of the structural part.

The building, at the beginning of the 70s, under ground consists of three parking floors with bidirectional waffle slabs. Above ground, the slabs are formed by solid 0.16 and 0.20 m thick concrete slabs resting on mixed alveolar beams (Boyle type), this structure being one of the first composite building structures executed in Spain. Between the second and third floors, there is a structural steel lattice girder on the façade that allows for the felling and consequent elimination of the supports at the entrance of the building.

The architectural program includes the elimination of a plant (mezzanine), and the demolition and subsequent reconstruction of the slabs of the basement to new levels, giving commercial use to the first of the new slabs below ground, and parking to the rest. On ground level, there are several actions that include rehabilitation: adaptation of the structure to the current regulations (CTE), elimination of one of the stairwells, closing and opening of new holes, etc.

The study of preexisting showed the need to reinforce some of the columns under ground (reinforced concrete) and with less range in the above ground (steel columns).

The demolition and emptying of the ground level was carried out under the shelter of a provisional support system for the perimeter walls.
