Delhi Metro Suspends All Excavation, Backfilling, Concrete Dismantling Works in View of Thick Smog in the City
In view of the thick smog in Delhi and adjoining areas since the last few days, the Delhi Metro management has decided to take the following measures at its construction sites with immediate effect:
Excavation/ Backfilling work to be suspended for five days.
Dry dismantling of concrete/ Brick likely to cause dust pollution and dry stone cutting to be suspended for five days.
DG sets to be stopped except those required for safety and security
Any other activity causing dust to be suspended for five days.
Additional Water sprinkling at all sites
These steps have been taken as compliance of the instructions given by the Delhi government regarding construction sites. As part of its work culture, the Delhi Metro accords very high priority to the issue of the preservation of environment, especially challenges such as dust control.
Water is sprinkled regularly to avoid soil erosion and dust pollution. Grass paving and tree plantation are also quick and effective means of dust control as grass covers and protects exposed loose soil when winds kick up as the soil stays put. The muck/soil generated from excavation is disposed off at designated areas using dumpers with tarpaulin cover on top. Wheels of trucks exiting construction sites are thoroughly washed before they enter public roads.
Motorized vehicles at sites are restricted to a maximum speed of 10-15 kilometers/hr. This results in less dust emission and improved safety. Toe dust accumulated on barricade boards is cleaned regularly to minimize road side dust pollution. This helps in keeping the road clean.
All construction activities are carried out in accordance with DMRC’s Environmental Policy. Implementation of this policy ensures compliance to all environmental legislations and regulations that may be applicable during construction. A number of environmental initiatives have been taken by the organisation under this policy.
All waste is segregated before disposal. To prevent land and water contamination, hazardous liquid wastes such as used oil and chemicals are disposed off only through government approved recyclers of such waste.
