The construction of the first phase of the Chennai Metro project in India is scheduled to be completed by spring 2015. During the construction cracks were detected in more than 200 buildings in Chennai. Though the apparent cause seems to be the tunnel boring machines, investigation has not yet confirmed it.
Although the necessary precautionary measures for weak buildings were taken, according to Federal Minister for Urban Development Kamal Nath, and careful, detailed instructions for tunneling work were proposed in project’s brief, the fact that 70% of the buildings were cracks appeared are very old cannot be neglected. “Incidents of cracks are largely unavoidable in such large-scale construction, particularly in congested areas where known methods of strengthening cannot be carried out", said S. R. Gandhi head of the Dept. of Civil Engineering at the Indian Institute of Technology (IIT) Chennai. The project consists of two corridors in total length of 45km from which the 24km will be underground and is administered by Chennai Metro Rail Ltd (CMRL) a joint venture of Government of India and Government of Tamil Nadu.
