So, steps are being taken to strengthen these houses to prevent any untoward incident as there will be heavy vibration during the tunnel digging process. Steel props, tilt meters, settlement markers and other monitoring equipment are being used in the exercise. The props are meant to support the structures from the inside as well as the outside. “The strengthening work will continue side by side as tunnel boring machine (TBM) Chandi will be digging the tunnel,” a senior KMRCL official said.

The residents can return to their respective houses once the tunnel-boring machines have passed under their residences. The Anadi Cabin, known for its lip smacking Moglai Paratha, will be closed for four days sometime by the end of this week. Regal Cinema and the Shalimar Hotel will also be closed for a few days when tunnel-boring machines will cut underneath the buildings. “The last lap of the tunneling from Esplanade to Sealdah will require around 14 months to complete,” the official said. A similar exercise of evacuating residents and strengthening buildings had taken place when the tunnels were built along Brabourne Road as part of the project.
