The cracks have been noticed at a time when the DMRC has begun trial runs on the much-awaited Yamuna Bank-Noida line, which is set to be opened for public by the end of August.
Shirish Patel and Associates, a consultant appointed to check Metro structures especially cantilevers on all the under construction Phase II lines, noticed the cracks.
Following the consultant's report, DMRC Managing Director E Sreedharan visited the site.
The cracks were spotted on Piers 10 and 14, which are located near the Indian Oil building in Sector 14 of Noida. Sreedharan said the crack on Pillar 14 was superficial, while he ordered a thorough inspection into the Pier 10.
The Noida stretch was constructed by Gammon India, which is also contractor of the Central Secretariat-Badarpur where the mishap occurred.
The trial runs on the 13.1-km-long Noida line have only been started on the Yamuna Bank-New Ashok Nagar stretch for now and will be extended to Noida City Centre Sector 32 after 10 days.
