The horror of the Jamrudpur Metro collapse came alive again on Saturday when fresh cracks were noticed on two piers with cantilevers on the under-construction Noida line. Trial runs on this Metro line, slated to open to the public by August-end, started only on Saturday. The piers were inspected by Delhi Metro Rail Corporation managing director E Sreedharan, who has ordered a detailed inspection of one of the cracks. The other, he observed, is superficial.
The pier which collapsed leading to the Jamrudpur tragedy also had a cantilever, which is a horizontal projection jutting out of the pillar. Cantilever piers are used at curves on the Metro line. Both the Badarpur line, where the mishap took place, and the Noida stretch have the same contractor, Gammon India. The matter came to light when the consultant — M/s Shirish Patel and Associates — appointed to check other Metro structures, especially cantilevers, on all the under construction Phase II lines noticed the cracks and informed DMRC of this. The consultant was appointed soon after the Jamrudpur mishap. The cracks were spotted on Piers 10 and 14 located near the Indian Oil building near Sector 14, Noida. After a thorough inspection, it was concluded that the crack on Pier 14 was superficial and not a matter of concern. But a further investigation was ordered into the one on Pier 10.
