Banco Popular New Headquarters

Madrid, Spain


The building occupies a built-up area of 103,000 m2 for office use and more than 20,000 m2 for services, with 1,600 parking spaces in a four-storey underground car park.

It consists of 4 large office blocks joined together by the roof floors and the floors below ground level. The base and crowning of the building serve as elements to grant visual unity, allowing for the interpretation of the whole set of buildings as one single element. The underground structure occupies the entire plot. These floors are dedicated to the uses of parking, access and control. The flooring in these areas has been solved by means of bespoke pre stressed reinforced slabs.

Four office modules of six floors each with reinforced concrete structures are raised above ground level. At one end there is also a module corresponding to the commercial area. Above ground, the slabs were made with 30 cm thick post-tensioned slabs, with spans of 10.40 m.

Large metal lattices have been placed on the roof floor. From these lattices the areas of mixed decking slabs of the penultimate floor are suspended. Part of these lattices constitute the bridges connecting the office modules together. The lifting of these bridges from the ground was performed by means of hydraulic jacks and is one of the most important challenges in the execution of this building, given the space constraints which conditioned the collection of materials and the auxiliary means to be used in operations requiring very high precision.

The supports of the structure are mainly reinforced concrete, except for some mixed support in the lower floors and the metallic supports of the facade. Coinciding with the vertical communications facilities of the office modules, the concrete walls that constitute the resistant cores have been executed to endure horizontal actions (wind and uneven earth pressure).
