A portion of a balcony slab above a third-floor window collapsed from a 40-year-old CIDCO building in Navi Mumbai’s Vashi area on Sunday, prompting all 16 resident families to begin shifting to alternative accommodation. No casualties or injuries were reported, officials said.
The incident occurred on Vashi-Koparkhairane Road in Sector 15. Rescue services were alerted after the slab fell from the G3 building, according to information cited by officials.
The affected building was constructed by the City and Industrial Development Corporation, or CIDCO, and is around four decades old. The collapse involved the slab above a window on the third floor, raising immediate concerns about the safety of residents living in the ageing structure.
Sixteen families currently live in the building. Following the incident, residents began vacating their homes in a phased manner. The families are making their own arrangements for alternative accommodation and are shifting gradually rather than leaving the building at the same time.
Officials confirmed that there was no loss of life in the incident and that no one was injured. The available information did not indicate whether any further portions of the building had been declared unsafe or whether residents had been provided with temporary accommodation by the authorities.
The incident has brought renewed attention to the condition of older residential buildings in Navi Mumbai, particularly structures built several decades ago. In this case, the immediate response has been led by residents, who have started moving to safer locations after the slab collapse.
The next steps will depend on the assessment of the building and the authorities’ response to the residents’ relocation. Further information on structural inspection, the building’s safety status and any official rehabilitation or accommodation arrangements was not available in the report.
