It is an important milestone in construction of Bengaluru suburban Rail Project, the BSRP said in a statement. The “Mallige’ line or Corridor-2 includes construction of around 8 km viaduct or elevated section, from Hebbal to Yeshvantpura, using such U-girders.
U-girders are U-shaped pre-tensioned precast girders that allow track to be laid right away. U-girders are widely used in metro projects all over the world since they not only ensure superior quality but also save construction time.
“So far, 28-metre-long U-girders have been used in other metros. These girders are cast in the yards and will be transported to the location and launched over piers using high capacity cranes/launchers,” the BSRP said. It requires careful planning and accuracy to cast these U-girders in casting yards, away from the cities, it added.
