Imperia, Italy

Imperia Italy Expansion and upgrading of the rail system in Northern Western Italy is a huge commitment to providing reliable public transport for the future.
Construction of any new railway line is always a difficult process, but when this involves such rugged coastline and requires multiple rock tunnels and viaducts across river valleys, the scale of the task is a real challenge.

Ferrovial Agroman will construct the new coastal railway section between San Lorenzo and Andora. The task consists of 18.8 km of line with 7 viaducts and 8 tunnels cut through the mountains, 1.4 km of the line is supported on viaducts, the remaining 17.4 km constructed as galleries and tunnels.
Artists imperssion of the New station and Viaduct at Imperia Nestled between the steep faces of the Maritime Alps and the Mediterranean Sea in North West Italy, is the province and city of Imperia. Founded in 1932.

The winding narrow access roads through the villages of Imperia made the small amount of materials needed for bi-directional testing a positive advantage over other methods of load testing.

Testing at Impero The testing requirements of the overall project were comprehensive with numerous tests required on piles as small as 1 m and up to 2 m in diameter. Bi-directional load testing was employed on three of the large diameter piles with the highest loads. Two of the auger bored piles were 1.4 m in diameter and bored to lengths of 12 m and 14 m respectively. The third test pile was 2 m in diameter and 24 m in length.
All the piles were socketed into the Limestone rock to a length of three diameters. The O-cell arrangements for each pile were placed 0.5 m to 0.7 m from the pile toe.
Successful testing of the limestone rock sockets on these three piles was achieved. In addition, the loading and unloading behaviour of the piles was required as if loaded from the pile head and this modelled successfully using the measured components.
