There has been a long delay in the tunnel construction for the proposed underground metro line from close to Mandi House to ITO in Delhi. The project executing firms – Shanghai Urban Construction Group (SUCG) and Larsen and Toubro (LandT) – have already received approval from the Delhi Metro Rail Corporation (DMRC) for the tunnel project.
Now they are awaiting permissions from the Railways for the project. The work is stuck for over two months as it crossed the Metro line above ground and reached till before the railway line. This tunnel crosses two major train crossings above the ground – a metro line and a railway line. So, the 350-tonne heavy tunnel machine is stuck underground, near the pillars of a railway line in crowded ITO. According to standard procedure, any tunnelling below a railway line requires the approval from the Commissioner for Metro Railway Safety which has been obtained.
