Ambitious design tests Rizzani
By Sarah Ann McCay26 August 2012
Italian contractor Rizzani de Eccher is using three Terex luffing jib tower cranes to carry out construction on a 166 m tall tower in Turin.
Challenges presented by the jobsite include overhanging floors and a cantilevered auditorium that will overhang from the main structure, as well as a narrow jobsite footprint due to two main roads on either side of the building and a public park.
Rizzani de Eccher is working with two 32 tonnes capacity Terex CTL 630s, one will have a final height of 184 m and the other 168 m, both with 4 collar supports and 12 climbing operations. The other luffer is a CTL 430, with a maximum capacity of 24 tonnes. Maximum height is 177 m with 4 collar supports and 12 climbing operations.
The 18-month build project includes the construction of underground floors and floor slabs using reinforced concrete, while the above-ground structures will feature three nuclei in reinforced concrete and a large steel structure positioned at a height of 35 m capable of bearing all vertical loads from the seventh to the 37th floor.
The new tower, which will house the group headquarters of one of Italy's leading banks, San Paolo IMI, will be Turin's second tallest building after the Mole Antonelliano, the city's major landmark. Designed by architect Renzo Piano, the new tower will house 2,000 staff and a centre for customer service operations.
