A compilation of the engineering challenges encountered during the construction of Delhi Metro’s Phase 3 titled, “Delhi Metro – Phase 3 Challenges” was unveiled on March 4 by Delhi Metro’s Managing Director, Dr. Mangu Singh and other senior officials.
The book written by DMRC’s Executive Director (Corporate Communication), Anuj Dayal focuses on the major civil engineering challenges that were encountered during the construction of the three main corridors under the third phase of expansion – the Majlis Park – Shiv Vihar Pink Line, the Janakpuri West – Botanical Garden Magenta Line and the Central Secretariat – Kashmere Gate Violet Line.
All these corridors were constructed through extremely congested residential as well as commercial areas. While the Pink Line passed through the Ring Road, the Magenta Line was constructed along the Outer Ring Road and the Violet corridor entered the congested old Delhi localities which had centuries old buildings as well as innumerable structures of historical importance.
Many unexpected engineering challenges were encountered while constructing these sections and DMRC’s engineers had to come up with out of the box solutions. At many locations, stations had to be redesigned while at many other sites, the movement of the gigantic Tunnel Boring Machines (TBMs) had to be re-planned.
The Delhi Metro has always laid great emphasis on compiling and archiving its activities so that the future generations can benefit. After the completion of Phase 2 also, a compendium of the major engineering challenges was released and was sent to all the major academic institutions and libraries.
Apart from the book, DMRC had also made a documentary film on its Phase 2 challenges. The film had received a national award (Rajat Kamal) back in 2011 in the ‘Best Promotional Film – Non-Feature films’ category. Audio video documentation of Phase 3 construction has also been done so that a similar film can be produced in the days to come.
