Gurugram, June 25 -- The Municipal Corporation of Gurugram (MCG) on Wednesday mandated corrugated galvanised iron (GI) or metal sheet barricading at all construction, reconstruction, demolition and excavation sites to curb dust pollution and improve air quality. The order, issued by MCG commissioner Pradeep Dahiya, follows directions from the Commission for Air Quality Management and provisions under the Environment (Construction and Demolition) Waste Management Rules, 2025. Officials said dust and fugitive emissions from construction activities are among the major contributors to air pollution in Gurugram and the National Capital Region (NCR). The order states, no construction or demolition activity can begin or continue unless the entire site perimeter is enclosed with corrugated GI or metal sheet barricading before work starts and throughout the project period. Temporary fencing, tarpaulin, cloth, tin sheets or mesh screens cannot be used as substitutes. Barricading must be made of opaque galvanised iron or colour-coated corrugated metal sheets with a minimum thickness of 0.50mm, fixed to a rigid steel framework, officials said. "Construction sites with a plot area of 500 square metres and above must have barricades at least three metres high, while other sites must maintain a minimum height of 2.4 metres. Along boundaries adjoining occupied buildings, schools, hospitals or busy roads, barricades must be 3.6 metres high or higher, depending on pollution-control norms," said Dahiya. MCG has also mandated full-height dust screening for structures under construction or demolition, with dust-screening fabric or green netting required on all exposed sides. No structure taller than one storey can continue construction without such screening, and demolition work can begin only after the structure is fully covered. Site operators must maintain barricades properly, prevent encroachment on public roads and display project details, including the builder's name, building plan sanction number and contact details of the person responsible for dust control. MCG will form a dedicated cell headed by a nodal officer, with a complaint mechanism requiring authorities to act within 24 hours, officials said. Violators may face stop-work notices, environmental compensation, penalties, sealing of premises, disconnection of water and electricity connections and blacklisting of contractors. Ongoing projects have 15 days to comply....
