Fifteen workers were rescued following a construction accident at a Gandhinagar site, with no casualties reported.
The metal slab collapse occurred at the Bosky The Empire site in Kudasan on Wednesday night during slab-casting work.
Twelve workers were hospitalised and remain stable, while three others with minor injuries were discharged from care.
Preliminary reports indicate a crane may have struck part of the ceiling during the slab-casting process, causing the collapse.
Rescue operations involving the Municipal Corporation, police, SDRF and NDRF continued overnight, using heavy cranes and cutting equipment.
The incident adds to a string of recent construction-related accidents reported across Indian cities this year, prompting renewed scrutiny of site safety standards.
Officials confirmed that all 15 workers involved in the incident have been accounted for, with none reported missing as of the latest update.
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.
