Like every winter, as the Air Quality Index rose to disturbing heights this November, the Delhi government formulated an intensified response plan and banned construction activities. This included not only banning cement, plaster/other coatings, cutting/grinding and fixing of tiles, stones, water proofing work, road construction activities, and major repairs, etc., from the earlier Graded Response Action Plan (GRAP) III but also added banning of construction activity in linear public projects such as highways, roads, flyovers, overbridges, power transmission, pipelines, telecommunications, etc. in GRAP IV.
