Fifteen workers were rescued after a metal slab collapsed at a construction site in Gandhinagar’s Kudasan area on Wednesday night.
The collapse occurred at the Bosky The Empire site during slab-casting work between two existing structures, with no casualties reported.
Twelve of the rescued workers were hospitalised and remain stable, while three others with minor injuries were discharged.
Officials believe a crane may have struck part of the ceiling during the slab-casting process, causing the collapse.
Teams from the Municipal Corporation, police, SDRF and NDRF worked overnight, deploying specialised cranes and cutting equipment to clear the site.
The Kudasan area of Gandhinagar has seen rapid commercial construction activity in recent years as the city has expanded its business and retail footprint.
State authorities said a detailed structural assessment of the remaining portions of the Bosky The Empire site would be carried out before construction work resumes.
Labour rights groups have periodically called for stricter enforcement of on-site safety supervision at construction projects involving simultaneous heavy-machinery operation and manual work.
The accident occurred around 9 pm on Wednesday at the Bosky The Empire construction site, where workers were casting a concrete slab between two existing structures.
Preliminary reports suggest a crane may have struck a portion of the ceiling while slab-casting work was underway, triggering the collapse.
Teams from the Municipal Corporation, district police, district administration, State Disaster Response Force and National Disaster Response Force were deployed to the site.
Rescue teams used concrete and metal cutters along with specialised cranes with lifting capacities of more than 300 tonnes to clear debris.
Three of the rescued workers who did not suffer major injuries were discharged after treatment, while the remaining 12 were kept under observation.
The debris-clearing operation continued through the night to ensure no workers remained trapped beneath the collapsed slab.
