An old concrete brutalist warehose

Abstract In 1975, an industrial warehouse was built near Madrid, designed by three of the most prestigious Spanish architects of the time. The warehouse was intended for the storage of products for a large commercial company. The building, covering approximately 40,000 m 2 with a symmetric, almost square floor plan, is a remarkable example of functional rationalist brutalist architecture. It was constructed using beamless reinforced concrete slabs and precast prestressed elements, addressing around 700 linear meters of loading docks around the perimeter. It features two large internal storage courtyards surrounded by internal access roads distributed across five levels. The building was constructed during a period of technological innovation in structural concrete, with the development of new calculation methods and materials, such as high‐strength steel (cold‐drawn and naturally hardened) and precast prestressed steel elements. However, as was common at the time, durability was not a key factor in the design or construction of the structure. This, combined with the fact that the building went out of use in the mid‐1990s, never underwent significant rehabilitation work, and suffered from severe degradation of the roof's waterproofing, led to a series of deterioration processes that now affect its remaining service life. The assessment of the building's structural capacity was hampered by the lack of descriptive documentation regarding the structure and its reinforcement schemes. Therefore, an extensive investigation campaign was necessary to analyze the structure and its constituent materials.
