Lait Parakh, a resident of Hauz Khas B1 block, says he can feel the vibration every time a Metro train passes through the tunnel beneath their homes. Despite several complaints to the Delhi Metro Rail Corporation (DMRC), Parakh said the problem hasn’t been resolved.

“Ever since the Metro started operations in the area, we have been facing the problem. We have made several complaints to the DMRC. It is a very unsettling feeling. We fear that the constant vibration might compromise the structural safety of our buildings,” Parakh said.

Less than a kilometre away is Sarvpriya Vihar, where residents have made similar complaints. Swati Mirza, a homemaker, said the problem has aggravated after the Magenta Line (Botanical Garden to Janakpuri West) was opened last year.

“There is a rumbling noise when a train passes through the tunnel. Sometimes, we get the feeling that there is an earthquake. The problem started after the Magenta Line was made operational. Last week, DMRC officials had visited our area. Since then, the noise has reduced,” Mirza said.

AAP MLA Somnath Bharti had raised the matter with the DMRC. Bharti said he had asked the DMRC to check the vibration levels at Sarvpriya Vihar and Begumpur village. “In Begumpur village, people complain of cracks in the building and constant vibration. People have complained of vibrations from other parts of my constituency as well,” he said.

DMRC officials said buildings cannot develop cracks from vibrations induced by train movement. Anuj Dayal, executive director, corporate communication, DMRC, said, “Vibrations and noise are a normal phenomenon whenever trucks/cars/airplanes or rail-based systems, including Metros, pass near any structure. The level of vibrations caused by the DMRC trains does not cause damage to the foundations or structural integrity of the buildings near the Metro tracks.”

Experts at CSIR-Central Road Research Institute (CSIR-CRRI) said 72VdB (vibration decibel)and above is when humans can feel the sound waves.

“Buildings or structures feel the effects of vibration only at 95-100 VdB and above. That is when buildings starts developing cracks. But there could be other reasons for cracks in buildings, such as the age of the structure,” Dr Nasim Akhtar, principal scientist, transportation planning and environment, CSIR-CRRI, said.

Dayal said, “Whenever complaints are received regarding vibrations, the DMRC examines the same technically and takes necessary mitigation measures to reduce the level of vibrations and noise by installing special elastomeric pads, noise barriers, wheel grinding of trains etc as needed.”
