Monday Metro mishap: Norms overlooked?
The Inquiry Report of October 2008 Laxmi Nagar incident had made it mandatory for the presence of one engineer from DMRC at every construction site, where heavy cranes and excavators or girders were being used, but DMRC failed to follow the norm
THE MONDAY mishap happened despite the presence of a heavy contingent of DMRC officials at the Zamrudpur construction site. Most importantly the DMRC MD E Shreedharan had himself visited the spot an hour before the incident that left six people injured after a mechanical fault in a heavy-duty crane.
It might be noted that the Inquiry Report of October 2008 Laxmi Nagar incident had made it mandatory for the presence of one engineer from DMRC at every construction site, where heavy cranes and excavators or girders were being used. But how such a qualified person failed to assess the situation and allowed to continue the work is still a mystery.
Sever senior officials and engineers of DMRC including Chief Project Manager SK Gupta, who is incharge of the Central Secretariat - Badarpur track, was present at the time of the accident. The incident happened when four heavy duty cranes — two of 250 tonne each, one crane of 350 tonne and another of 450 tonne were trying to bring down the remaining portion of the collapsed girder.
During the operation, one 250 tonne capacity crane developed mechanical failure as its boom developed cracks and snapped. Consequently, the boom of adjacent crane snapped and one crane toppled down. The Gammon India is also constructing New Ashok Nagar to Noida City Centre Metro line.
The DMRC officials and contractor Gammon India Ltd were directed to follow extra precautions after the accident on Sunday. In the accident, six people were dead and over a dozen were hospitalised in different hospitals of the city.
The Metro chief himself visited the site on Monday and inspected the rescue operation going on. From there he came to Metro Bhawan to attend a meeting but meanwhile heard about second mishap and rushed back to the accident site.
The DMRC has brought six new cranes to the accident site to removes the debris of the cranes that collapsed. “The cranes are brought to the site and are in the process of clearing the debris,” the official said. Metro Spokesperson Anuj Dayal said Monday’s accident took place when one of the high capacity cranes developed mechanical failure as its boom developed cracks and snapped. “As a consequence, extra weight came on the booms of the other adjoining cranes leading to snapping of booms of two other cranes and the toppling over of one of the cranes,” he said.
Dayal said the weight of the portion of launching girder that was being lifted by the cranes was about 200 tonnes and that the three crane operators involved were unharmed in the incident.
“About 80 per cent of the damaged launching girder has fallen to the ground while about 20 per cent is still on the concrete span,” he said, adding that the launcher is now being cut into pieces with the help of gas cutters.
The residents of the vicinity, who witnessed the accident blamed the rescue operation officials for the incident.
After the accident, the DMRC has decided to cut the damaged launcher which is to be removed into pieces with the help of gas cutters. “The decision to remove such a heavy structure in such a congested place was too risky. If the officials could have taken the decision to cut the launcher and remove it in pieces the incident would have been averted,” said Desh Raj Choudhary, a resident of the area.
