They were several interventions in the “Mutua de Terrassa” Headquarters building: the renovation and consolidation of the historical building, the enlargement of the vertical communications, the metal emergency staircase and the extension of the underground with three extra floors.
The structural design was with enamelled steel plate over a metal structure, stabilized by the nucleus concrete walls.
The evacuation staircase hangs from the roof by means of steel trusses.
