Metro construction works are spread all over India. Apart from the design of permanent works there are several enabling/temporary structures required during construction of permanent works.

Er. Swaroop Maiti and Er. Vivek Abhyankar discuss the various types of temporary works used in the underground metro construction projects and in elevated metro projects, and also address queries by both budding and senior engineers.
