FCC will be building the Torre Zero Zero skyscraper on Calle Diagonal for the Zona Franca -Free Zone- of Barcelona, for 21 million euro in a 15-month completion period.

The contract is for the structure and the above-ground architecture of a 24-story building with 34,000 m2 of floor area for office use.

Standing 118 metres tall, the building has a structural scheme based on a double vertical system of pipes. There is the inner core made of concrete, which will absorb horizontal thrust and will contain the communications systems (stairways, lifts, yards for machinery and services). Then there is the façade's structure, comprising a double set of parts: the vertical supports for the inner façade and the tilted components of the outer façade, which act together through the unions expertly arrayed along the floor levels.
