K-RIDE successfully installed the first 31-metre-long single-span precast U-girder — the longest in India — on the Mallige Line of the Bengaluru Suburban Railway Project (BSRP).

K-RIDE officials stated that the U-girder, cast at Gollahalli in January 2024, was launched between 9.45 p.m. and 10 p.m. on Tuesday at Yeshwantpur as part of the construction work for the Baiyappanahalli-Chikkabanavara line.

“U-girders are U-shaped, pre-tensioned, and precast structures commonly used in rail-based public transport projects. Their design enhances quality and expedites construction by reducing the need for multiple foundations and piers due to their extended length. The U-Girder is a critical structural component of the elevated track. It forms the base for laying the tracks and other systems component such as traction and signaling,” a official explained.

The installation was carried out using two high-capacity cranes, ensuring precision and safety throughout the process, according to officials. K-RIDE has stated that 450 U-girders will be installed on the 8 km elevated section of the Mallige Line between Hebbal and Yeshwantpur. To date, nearly 60 U-girders have been cast at Gollahalli.

Rail Infrastructure Development Company (Karnataka) Ltd. (K-RIDE) is the government agency responsible for executing the 149-km BSRP.
