Delhi opens a Shastri Park room that watches 700 construction sites for dust

Chief Minister Rekha Gupta opened an Integrated Command and Control Centre for the Delhi Pollution Control Committee on Thursday 1 October. The room is at the Delhi Metro Rail Corporation's IT Park in Shastri Park. Environment Minister Manjinder Singh Sirsa said more than 700 construction sites, each larger than 500 square metres, are on AI-assisted CCTV, and that a rise in PM10 at a watched site will trigger an alert to the department and to the site owner.

Gupta described the job as more than collecting readings. She said the point was to turn the data into field action with a result that can be checked. The government phrase for the loop is detect, analyse, act, verify. In winter the centre is supposed to task 78 teams at subdivision level. Pollution teams called Vayudoot will wear body cameras when they move against road dust, open burning and construction breaches. The centre will also watch the city's air-quality stations, compare them with earlier years, and track where the road-sweeping machines actually are.

The 500-square-metre cut is the operational choice that decides who feels this. Delhi's dust problem is not only large towers. It is also small plots, debris trucks and roads that are dug and left. A system aimed at sites above 500 square metres can see the big contractors. It does not, on Sirsa's description, automatically see the one-plot job. The alert he described is a PM10 rise at the monitored site, sent to the owner and the department. That is a sensor threshold, not a lab case. How high the rise has to be, and how fast someone has to answer, is not in the launch remarks.

Body cameras on the Vayudoot teams are the part that changes the inspection, not the dashboard. A reading in Shastri Park is a number. A clip from a site visit is evidence an owner can contest or a court can watch. Making the cameras mandatory for industrial inspections, as the government has said, also creates a record of what the inspector did. Delhi's pollution enforcement has often failed in the gap between a notice and a follow-up. A camera does not close that gap by itself. It makes the gap harder to deny.

Winter is the test the launch is built for. From October the city's air is a mix of local dust, vehicles, industry and the farm fires that arrive from outside the capital. A command centre in Shastri Park cannot see a field in Punjab. It can see whether a listed construction site in Delhi is throwing dust on a day the regional load is already high, and it can send one of 78 teams. That is a narrower promise than a clean-air announcement, and it is the promise that can be checked in a month: how many of the 700 sites produced an alert, how many alerts produced a visit, how many visits produced a stop-work order.

Sirsa's figure of more than 700 sites is the baseline. If the number of watched sites does not rise, and if the PM10 alerts are not published, the centre is a room with screens. Gupta's launch line, that technology has to become field action, is the standard the same government set for itself on 1 October. The first winter under that standard has just started.
