A day after the a part of a staircase of an Eastern Express Highway subway near Ramabai Colony at Ghatkopar collapsed, the civic body has started repair work of the pipeline that burst due to the cave-in.
Sources in Brihanmumbai Municipal Corporation (BMC) said the ground that was dug to lay the pipeline sometime ago, was not levelled properly after the work was complete.
The cavity that was created after the rains resulted in the collapse, they added.
The BMC started the repair work of the 450mm pipe that burst. One side of the subway, which leads towards Mulund, has been barricaded, but the pedestrians will not be inconvinienced, confirmed an official.
“The BMC has undertaken the work of repairing the pipeline. The Public Works Department said that the repair work of the subway will be undertaken once the pipeline is repaired,” said Assistant engineer of Ghatkoper (East), S N Dwivedi.
The pipeline that burst was a part of the project undertaken by the Water Supply Projects of the civic body to bring in additional water to the city.
The Vibhag Pramukh, Bhalchandra Shirsat, said, “The subway was leaking although it was built in 2003. Now at least some fabricated skywalk should be built for the residents’ convenience.”
The BMC is trying to ascertain the cause of the cave-in. Sources said negligence of contractors and careless trenching work could have led to the cave-in.
