Minor cracks have developed on 18 piers on three corridors of the Delhi Metro and the DMRC has asked a consultant firm to examine the locations to take "corrective measures", taking no chance after the July 12 mishap that killed six persons.
Describing the cracks as "hairline" ones, the DMRC said these were noticed by DMRC engineers and Shirish Patel and Associates, who conducted a structural audit on all the Metro corridors which are under-construction now.
"They found hairline cracks on eight piers of the Central Secretariat–Gurgaon corridor, two piers of the NOIDA corridor and eight piers of the Central Secretariat–Badarpur corridor. All appear to be minor in nature," DMRC Chief Public Relations Officer Anuj Dayal said.
"DMRC will carry out further corrective action if required and take necessary remedial measures after Shirish Patel and Associates have examined these locations," Dayal said.
Meanwhile, DMRC Chief Sreedharan visited several of the sites where the piers have developed cracks and inspected it personally. He has been visiting the sites from Saturday.
The developments came on a day when a meeting of the board of directors discussed the report submitted by Prof A K Nagpal panel that went into the Zamrudpur incident.
There were reports that some officials have faced action after the board meeting, but there was no official word.
