Complete Rehabilitation of the building of ‘Bank Of Spain’ former branch In Pamplona

The Directorate General of Heritage (under the Ministry of Finance) promoted the rehabilitation of the building that until the early years of this century housed the Pamplona’s branch of the Bank of Spain. The building, which had been built around 1925, in the future will be used to house offi ces of the Ministry of Labor. This has one basement, ground fl oor, 1st to 4th fl oors and gabled roof.

Such rehabilitation involved large architectural changes inside of that building, but kept the hallmarks of it, such as the external façade (towards Paseo de Sarasate and San Ignacio Av.) and cover material. These changes in the interior, combined with adapting to the current standards and greater live loads to be resisted, forced in most of floor slabs (executed at the time with metal profiles and infill ceramic) to add mullions beams (section IPE).

The new floors are composite, with 60-mm-height steel decking (plus 60 mm of compression layer) and are supported by the mullions and existing beams and girders, some of which also had to be reinforced. As a matter of gauge, on the 3rd floor ceiling, preexisting joists had to be removed.

Likewise and for the same reason that the floors, almost all existing pillars (metal, double channels tied together) were reinforced by metal fasteners (UPN, plates, in some cases more clips, etc.) transforming them into closed sections.

The new architecture also forced to open some passing-holes in loadbearing walls. To do this, it was necessary to lo introduce cap beams (double IPEs). Also, there are new elevators, skylights, canopies, ramps, etc., each with its associated metal structure.

The roof structure had to be reformulated in its entirety, although this keeps the exact previous geometry and fi nish. The new structure has been executed with tubular profiles and UPNs, except for a special frame that had to be designed with especially light profi les (HEA sections).
