On the occasion of Republic Day, the Delhi Metro Rail Corporation Limited (DMRC) achieved a major feat in its priority corridor work by erecting the first ever U-girder between two pillars near Bhootnath Station in the Patna Metro Project. Rail tracks can be placed on the U-girders which are precast and pre-tensioned structures as per the timeline. It will play a major role in the timely construction of the project which is slated to be completed by 2026.
The precast structure will ensure better quality and help in saving time in construction, which will be set up at the site with the assistance of high-capacity cranes. Construction of U-Girder is essential as it needs to clear all the initial testing before it is installed.
According to DMRC, a total of 308 U-Girders which weigh around 160 tonnes has been planned to be constructed in the priority corridor. The priority corridor where the Girders is slated to be erected is 7.4km long in stretch from Malahi Pakri to Patliputra Bus Terminal.
