The MMRDA squad will see to it that the barricades of Metro projects meet the mandated 25ft height requirement and that no debris is seen outside these barricades. Its task also involves ensuring removal of debris from the sites immediately and sprinkling of water at regular intervals when excavation works are undertaken.
To ensure that the areas are not rendered unattractive by construction work, these officials will see to it that the median stones are painted in yellow and black strips. Metropolitan commissioner Sanjay Mukherjee has also directed that all areas where projects have been completed or are underway are properly lit.
Another team will visit these project sites every week to assess compliance and submit their reports to the development authority.
More than two dozen projects, including seven Metro corridors, the Mumbai Trans-Harbour Link, the Sewri-Worli connector and the Santacruz-Chembur Link Road, are under execution. Apart from this, MMRDA also maintains the Bandra-Kurla Complex area, where underground terminus work for the Mumbai-Ahmedabad high-speed corridor aka bullet train line is in progress. There are projects in satellite townships of Mumbai like Mira-Bhayander, Kalyan and Airoli where road works have been undertaken by the MMRDA.
As per the BMC’s guidelines issued on October 25, 25ft-high barricades must be erected at Metro project sites to keep construction debris in and the sites have to also be covered with tarpaulin/green cloth/jute sheets. Additionally, smog guns or water sprinklers have to be used during construction work. The BMC’s norms are applicable for other agencies like the Slum Rehabilitation Authority, the Maharashtra Housing and Area Development Authority, the Maharashtra Industrial Development Corporation and the Maharashtra State Road Development Corporation, too.
MMRDA said that it is implementing dust mitigation measures at construction sites with the use of water sprinklers. It has also asked contractors to ensure that vehicles carrying loose excavated earth are covered with tarpaulin and the debris is stacked in a way that minimizes dust emission. MMRDA said the debris is disposed of at designated locations regularly.
