Despite several constraints induced by the second wave of the Covid–19 pandemic in the last few months, the Delhi Metro Rail Corporation (DMRC) continued with the construction work of its Phase-4 corridors and achieved important construction landmarks as well.
A senior DMRC official said some of the important works including the tunneling work between Janakpuri West and Krishna Park Extension on the Janakpuri West – RK Ashram Marg corridor for DMRC’s first underground section of Phase-4 achieved during this period, he said. During these months, theb DMRC completed the tunneling of 500 metres of one of the 2.8 kilometre long twin tunnels and casting of over 50 per cent of tunnel segments in the casting yard.
The official said in the same stretch, DMRC achieved another major milestone by erecting Phase 4’s first ever T-girder at Mukarba Chowk last month. “These T-girders are pre-tensioned and are cast at the casting yard in Mundka. After casting, these girders are brought to the site and launched with the help of two mammoth 400 MT capacity cranes. The length of each girder is 37 metres and weight is around 90 MT,” he said.
On the Tughalakabad — Aerocity corridor, the casting yard at Panchsheel Park was prepared for casting with installation of all necessary equipment such as the erection of gantry cranes, he said.
The Aerocity — Tughlakabad Metro corridor, colour coded silver will connect the Kashmere Gate — Raja Nahar Singh Violet Line with the Airport Express Line. During this period, all Covid related guidelines given by the government from time to time were also stringently followed. After the lifting of Covid related restrictions, now there is a gradual increase in the manpower available at DMRC’s sites, he said.
