Last U-girder launched in presence of Metro chief, others

The Delhi Metro Rail Corporation on Tuesday launched the last girder of the Noida-Greater Noida corridor in the presence of DMRC managing director Mangu Singh, Noida Metro Rail Corporation (NMRC) MD and Noida Authority CEO Alok Tandon and other senior Metro officials.

30-km-long corridor

With the launch of the last girder between Sector 143 and Sector 144 stations, the viaduct of this approximately 30-km-long corridor has been completed. Civil work on this corridor began in May 2015 and the first girder was launched in December 2015. Within a span of 22 months, the DMRC has put up a total of 2,830 girders (2,035 U-girders and 795 I-girders).

The DMRC had successfully executed the task of launching 200 U-girders – the maximum number of U-girders launched in any metro corridor in India within a month — on the Noida-Greater Noida corridor in May 2016. The DMRC used six special trailers to transport the girders and six special cranes of around 350/400 tonnes capacity to launch the 27-m-long and 5.05-m-wide U-girders.

World record

The DMRC also entered the Limca Book of Records with this feat and Mr. Singh was formally handed over the certificate in March.

“The viaduct on the Noida-Greater Noida corridor was constructed by a specialised technique of precast pier caps and precast U-girders. The main challenge was precision in casting and launching U-girders which required specialised cranes of 350/400 tonnes capacity,” said a senior official of DMRC. All the girders were pre-fabricated at two casting yards located in Noida Sector 149 and Depot Station in Greater Noida, and each weighed approx. 153 tonnes.
