With Richard Meier he designed in cooperation with Arup, one of the world’s largest multinational Ponte Cittadella in Alessandria, . Benini has won engineering firms. The construction was completed by Torno competitions all over the world. In 1997 he founded the DOBP, Internazionale Spa, a major Italian civil engineering company Dante O.

Such are the “Piazza Valtellina” buildings: a large glass and steel sail provides continuity and roundness to the structure overlooking Via Valtellina, thanks to the glass walls that allow a view of the inside gardens, completely integrated with the outside sidewalk. It is located in the Scalo Farini area in Milan, behind the Monumentale cemetery and the Garibaldi railroad station. With strong industrial culture, this area of the city has long been trying to create its new urban role, which has recently undergone a deep transformation through the emergence of a high quality office development, “Piazza Valtellina.”

The building complex is located near the Garibaldi-Repubblica district, headed to become a new focal point for city life with its Città della Moda, Townhall, the new offices of Regione , and a 100,000 sq m park, the Giardini di Porta Nuova.
