'DMRC will carry out further corrective action if required and take necessary remedial measures after Shirish Patel and Associates have examined these locations,' Dayal added.

While residents in Noida have expressed fear that DMRC is in a hurry to conduct trial runs on the nearly finished stretch, the company said that surface cracks in concrete structures are not uncommon and trials are likely to continue along with the investigation.

'There is no need for panic in the matter. In fact, Indian standard codes for design of reinforced concrete structures allows and permits tension cracks within limits,' a DMRC statement said.

For further investigation, ultrasonic and rebound hammer testing will be carried out to check the integrity and quality of the concrete.

'DMRC will get load testing done wherever considered necessary,' Dayal said.

'Similar testing was done during phase I of the construction also as a precautionary measure whenever required.'

Meanwhile, the DMRC is expected to make public the report about the July 12 accident at a press conference Sreedharan is to hold Tuesday.

An expert committee led by Indian Institute for Technology's (IIT) A.K. Nagpal prepared and submitted the report last week which delved into design or construction material inefficiency as the cause for the mishap, said to be the worst in Delhi Metro history.
